Mexican migrant ethnopharmacology: pharmacopoeia, classification of medicines and explanations of efficacy

Determinants of Self-Medication in Immigrants: A Systematic Review

Immigrants intended to more rely on self-medication because of the difficulty of accessing formal healthcare in host countries. Negative consequences could occur when self-medication was inappropriate. This study aimed to systematically explore the prevalence, sources and determinants of immigrants' self-medication and the extent of their inappropriate self-medication episodes. PubMed, Scopus, SpringerLink, and ScienceDirect were used for data searching. The search date was 10th June 2023, with no beginning date to limit searching articles. Thirty-two studies were included. The prevalence of immigrants' self-medication presented from 18 studies ranged between 20.2% and 94.6%. Major sources of immigrants' self-medication were commonly obtained from their home countries, local markets or shops, and informal networks. The determinants of immigrants' self-medication were systematically collated into four themes: (1) illness and self-medication perception, (2) access to healthcare and medication, including 6 dimensions: accessibility, availability, affordability, acceptability, awareness and accommodation, (3) worry, and (4) predisposing factors of immigrants. About 46% of immigrant's self-medication episodes were inappropriate, especially antibiotic use. About 66% of the included studies described antibiotic self-medication. Prevalence rates of self-medication among different immigrantsvaried based on different time frames, context of diseases and migrated countries. Immigrants' cultural health belief, facing significant worry about job security, legal status, and cultural barriers influenced their self-medication. When immigrants have greater availability, accommodation, awareness, accessibility, acceptability, and affordability of health services in host countries, they are less likely to use self-medication. The predisposing factors like age, income, work status and immigrants' language also influenced their self-medication.

Utilization of traditional healing practices from Mexico by U. S. women of Mexican origin: A systematic review

Hispanics are 18.7 % of the U.S. population, and people of Mexican origin are 61.4 % of that Hispanic community. National health surveys indicate that utilization of traditional medicine among Hispanics is low compared to non-Hispanic Whites. However, many researchers have described their use in Hispanic populations as commonplace.

OBJECTIVE

This review analyzed studies about traditional healing practices from Mexico (THPM) used by women of Mexican origin in the U.S. for a greater understanding of traditional health practices within U.S. communities of Mexican origin.

DATA SOURCES

Journal databases were searched for studies between January 1, 1990 and December 31, 2020.

STUDY SELECTION

The Whittemore and Knafl and Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) methods were used to analyze the studies.

DATA EXTRACTION

Seven themes emerged: A) foundations, B) medical pluralism, C) non-disclosure and patient satisfaction, D) remedies and rituals, E) healers, F) affinity, and G) what clinicians need to know. Four subthemes were identified: G1) cultural sensitivity, G2) communication skills, G3) leveraging the influence of THPM, and G4) scientific inquiry.

DATA SYNTHESIS

U.S. women of Mexican origin reported continued use of THPM for health promotion, influenced by their understanding of health and illness, community ties, and personal experiences. Study authors recommended strategies for improving patient-provider communication and understanding patients' use of traditional health and healing practices.

CONCLUSION

Further explorations of THPM are needed to build awareness of culturally-tied health beliefs and behaviors that improve medical care experiences and quality for Hispanics of Mexican origin.

Bioprospecting of Five Ocimum sp. Cultivars from Croatia: New Potential for Dietary and Dermatological Application with Embryotoxicity Tests

Ocimum basilicum L. is the most common Ocimum species, and it is used as an ornamental plant and in food condiments. This unique study examined the chemical composition and biological activities of six extracts from five basil cultivars, including their antimicrobial, antidiabetic, antilipidemic, neuroprotective, and anticollagenase activity. Moreover, their toxicological effects were studied using the zebrafish Danio rerio. Volatile components were determined using HS-SPME and GC-MS, while total polyphenols were detected using HPLC and the spectrophotometric Folin-Ciocalteu method. Spectrophotometric assays (DPPH, ABTS, ORAC, FRAP) were performed to determine antioxidant activity, collagenase inhibition, acetylcholinesterase inhibition, and pancreatic lipase inhibition. Antimicrobial activity was determined using the broth microdilution test. The study found that the biological activities of different basil cultivars varied depending on the proportion of active compounds, as determined by chemical analyses. All six basil extracts significantly inhibited α-amylase, while Purple basil extract most significantly inhibited the activity of collagenase, acetylcholinesterase, and pancreatic lipase. Purple basil and Dark Opal basil I extracts exhibited the highest antimicrobial activity, while the Dark Opal basil II extract had the most significant antioxidant potential. The findings in this study suggest that ethanolic basil extracts have the potential to be used as dietary drugs and implemented in antiaging products. This study is unique in its aims to compare the chemical composition and biological activities of basil cultivars from Croatia and to evaluate potential toxicological effects through embryotoxicity tests on zebrafish Danio rerio embryos, and it reports the first evidence of anticollagenase, antidiabetic, and antilipidemic activities for these cultivars.

Narratives of Herbal Medicine Utilisation in the United Kingdom: Scoping Literature Review

Using thematic analysis of existing literature, this scoping review aims to explore the narratives of people using herbal medicine (HM) in the United Kingdom. Understanding who is using HM and why will enable better ways of facilitating the use of HM, as well as assist in designing future research. Ethnic groups were found to be primary users of HM in the United Kingdom. A sense of heritage continues to be important for these participants as it allows tradition and culture to stay alive within communities, as well as the ritualistic purposes of these plants. For women, another key demographic, concepts surrounding the naturalness of HMs are associated with the idea of femineity and self-healing. A reoccurring theme in the literature focusing on both ethnic groups and women's perceptions is the judgement from healthcare practitioners/professionals (HCPs) when addressing the use of HM. However, studies that investigated the perceptions of HCPs on HM confirmed that they often were supportive of using HM where standard treatments had been unsuccessful, and if a patient had anecdotal evidence of a herb having been effective. Delving deeper into public narratives of HM usage will allow conventional healthcare systems to effectively integrate alternative approaches, as well as ensuring that future research into the benefits of HMs is relevant to how people use them.

The Importance of Keeping Alive Sustainable Foraging Practices: Wild Vegetables and Herbs Gathered by Afghan Refugees Living in Mansehra District, Pakistan

The issue of foraging for wild food plants among migrants and relocated communities is an important one in environmental studies, especially in order to understand how human societies rearrange their practices linked to nature and how they adapt to new socioecological systems. This paper addresses the complexity of Traditional/Local Environmental Knowledge (LEK) changes associated to wild vegetables and herbs across four different groups of Afghan refugees living in Mansehra District, NW Pakistan, since 1985. Via interviews with eighty study participants, forty-eight wild vegetables and herbs were recorded, representing both the past and present wild plant gastronomic heritage. The majority of the quoted wild plant ingredients were only remembered and no longer actively used, thus suggesting an important erosion of LEK. Moreover, the number of wild vegetables and herbs currently used by Afghan Pashtuns engaged in farming activities is much higher than those reported by the other groups. The findings indicate that practiced LEK, i.e., knowledge that is continuously kept alive via constant contact with the natural environment, is essential for the resilience of the biocultural heritage, which is, however, also influenced by the rearrangement of social life adopted by refugees after relocation.

Dinâmicas de conhecimento e uso de plantas medicinais em um assentamento rural de Belém do Pará - PA

Resumo Os agricultores familiares que vivem em áreas de assentamentos rurais estão entre os diversos grupos sociais da Amazônia que detêm um amplo conhecimento sobre o uso de plantas medicinais. Estudos realizados neste contexto revelam uma vasta heterogeneidade no conhecimento e uso de plantas medicinais, bem como a influência dessas comunidades na diversidade vegetal e nos aspectos culturais associados ao seu uso. Esta pesquisa traz informações sobre a dinâmica do conhecimento e uso de plantas medicinais no Assentamento Rural Paulo Fonteles, estabelecido desde o ano de 2006 no Distrito de Mosqueiro, Município de Belém, estado do Pará. Os dados foram obtidos através de entrevistas semiestruturadas e oficinas participativas e analisados qualitativa e quantitativamente. As plantas medicinais são recursos prioritários para os assentados em períodos que antecedem e sucedem a ocupação. Foram registradas 140 plantas medicinais, das quais, 119 foram identificadas e pertencem a 58 famílias botânicas. Sessenta espécies são nativas do Brasil, sendo 21 com domínio fitogeográfico restrito a Amazônia e 59 são introduzidas. O conhecimento local de plantas medicinais encontra-se bem difundido entre informantes de diferentes classes de idade e gênero. As pessoas provenientes de outras regiões do Brasil reportaram um acervo de plantas medicinais significativamente maior do que àquelas naturais do estado do Pará. Entre as 140 plantas mencionadas, 110 referem-se a espécies cujos usos foram mantidos ao longo do tempo pelos informantes. A heterogeneidade sociocultural e a dinâmica do modo de vida dos assentados rurais contribuem para o acúmulo de saberes e no incremento da diversidade da flora local.

Phytotherapies in motion: French Guiana as a case study for cross-cultural ethnobotanical hybridization

BACKGROUND

French Guiana is characterized by a very multicultural population, made up of formerly settled groups (Amerindians, Maroons, Creoles) and more recent migrants (mostly from Latin America and the Caribbean). It is the ideal place to try to understand the influence of intercultural exchanges on the composition of medicinal floras and the evolution of phytotherapies under the effect of cross-culturalism.

METHODS

A combination of qualitative and quantitative methods was used. Semi-directive interviews were conducted in 12 localities of French Guiana's coast between January 2016 and June 2017, and the responses to all closed questions collected during the survey were computerized in an Excel spreadsheet to facilitate quantitative processing. Herbarium vouchers were collected and deposited at the Cayenne Herbarium to determine Linnaean names of medicinal species mentioned by the interviewees. A list of indicator species for each cultural group considered was adapted from community ecology to this ethnobiological context, according to the Dufrêne-Legendre model, via the "labdsv" package and the "indval" function, after performing a redundancy analysis (RDA).

RESULTS

A total of 205 people, belonging to 15 distinct cultural groups, were interviewed using semi-structured questionnaires. A total of 356 species (for 106 botanical families) were cited. We observed that pantropical and edible species hold a special place in these pharmacopeias. If compared to previous inventories, 31 recently introduced species can be counted. Furthermore, this study shows that the majority of the plants used are not specific to a particular group but shared by many communities. However, despite this obvious cross-culturalism of medicinal plants between the different cultural communities of French Guiana, divergent trends nevertheless appear through the importance of 29 indicator/cultural keystone species in 10 cultural groups. Finally, we have emphasized that the transmission of herbal medicine's knowledge in French Guiana is mainly feminine and intra-cultural.

CONCLUSION

French Guianese medicinal flora is undoubtedly related to the multiple cultures that settled this territory through the last centuries. Cultural pharmacopeias are more hybrid than sometimes expected, but cultural keystone species nevertheless arise from a common background, allowing to understand, and define, the relationships between cultural groups.

Traditional Herbal Medicine in Mesoamerica: Toward Its Evidence Base for Improving Universal Health Coverage

The quality of health care in Mesoamerica is influenced by its rich cultural diversity and characterized by social inequalities. Especially indigenous and rural communities confront diverse barriers to accessing formal health services, leading to often conflicting plurimedical systems. Fostering integrative medicine is a fundamental pillar for achieving universal health coverage (UHC) for marginalized populations. Recent developments toward health sovereignty in the region are concerned with assessing the role of traditional medicines, and particularly herbal medicines, to foster accessible and culturally pertinent healthcare provision models. In Mesoamerica, as in most regions of the world, a wealth of information on traditional and complementary medicine has been recorded. Yet these data are often scattered, making it difficult for policy makers to regulate and integrate traditionally used botanical products into primary health care. This critical review is based on a quantitative analysis of 28 survey papers focusing on the traditional use of botanical drugs in Mesoamerica used for the compilation of the "Mesoamerican Medicinal Plant Database" (MAMPDB), which includes a total of 12,537 use-records for 2188 plant taxa. Our approach presents a fundamental step toward UHC by presenting a pharmacological and toxicological review of the cross-culturally salient plant taxa and associated botanical drugs used in traditional medicine in Mesoamerica. Especially for native herbal drugs, data about safety and effectiveness are limited. Commonly used cross-culturally salient botanical drugs, which are considered safe but for which data on effectiveness is lacking constitute ideal candidates for treatment outcome studies.

Urban medicinal plant use: Do migrant and non-migrant populations have similar hybridisation processes?

ETHNOPHARMACOLOGICAL RELEVANCE

Urban migrant herbal medicine is an important topic on a global scale. Through bibliographical analysis of published studies we can get an overview of the different hybridisation processes at work in cities around the world, the main medicinal plants used and the principal ailments treated. We analysed the differential characteristics of urban ethnobotanical studies involving transnational migrant and non-migrant populations, in order to contribute useful information for the design of public health policies.

MATERIALS AND METHODS

A systematic and integrative revision was conducted, leading to a final selection of 66 primary sources, including studies with and without immigrants. In both cases, richness (S), considered as the sum of all species cited in the work, botanical families and reported ailments were recorded. Based on the work of Ladio and Albuquerque (2014) the main hybridisation processes identifiable in the literature were assessed. These were: fusion, relocation, re-combination of different species, their restructuring as medicinal targets, spatial segregation in usage, innovations found in the circulation and consumption of the plants, and the presence of simultaneous coexistence of different symbolic universes in plant medical practices.

DATA ANALYSIS

This was qualitative and quantitative, including both in-depth interpretative content analysis of the studies and frequency analysis of numerical data, such as species richness, botanical families, ailments and the hybridisation processes detected. A multinomial logistic regression model was used to analyse whether the probability of medicinal plant hybridisation processes occurring was the same in literature with and without migrants.

RESULTS

A total of 522 medicinal species formed part of the main urban ethnobotany worldwide; the majority were cosmopolitan in distribution and belonged to the Asteriaceae and Lamiaceae families. Only 21% of these species appeared in both migrant and non-migrant studies. Most were used for gastrointestinal and hepatic ailments. Surprisingly, culture-related illnesses were not frequently mentioned, probably due to lack of recognition and re-interpretation by authors. Logistic analysis showed that in the studies with migrants, relocation and restructuring of plant use were the most frequently identified processes, while in the studies involving only non-migrants fusion was 4 times more likely to be found than in studies with migrants.

CONCLUSIONS

Our research on hybridisation processes shows that cities constitute an environment that fosters a rapid exchange of practices and knowledge about the available species. Studies with migrants have shown that they reproduce traditional models in their use of plants, and so relocation and restructuring of their herbal medicine are the principal processes. Health risks in this case are related to the difficulties faced by these groups in obtaining their plants and reproducing their practices. In the case of fusion processes observed in non-migrants, who do not normally have a long history or much experience of plant use, errors or poisoning may result from misuse. This information highlights the importance of considering these processes in health policies, particularly when there are no significant quality controls of these resources.

Matricaria genus as a source of antimicrobial agents: From farm to pharmacy and food applications

Matricaria is a widespread genus of flowering plants of the family Asteraceae that grow in temperate regions of Europe, Asia, America and Africa. Some of the species are also naturalized in Australia. Some species of this genus such as Chamomiles are recognized medicinal plants and cultivated in several countries for commercial purposes: to obtain its blue essence, as herbal tea, and for pharmaceutical or cosmeceutical uses. The phytochemical composition of Matricaria spp. includes volatile terpenoids (e.g., α-bisabolol, bisabolol oxide A and B, β-trans-farnesene and chamazulene), sesquiterpene lactones such as matricin, and phenolic compounds (flavonoids, coumarins and phenolic acids). Their essential oil is obtained from the fresh or dried inflorescences by steam distillation, and additionally cohobation of the remaining water. The volatile composition of the essential oil, especially the content of the valuable components α-bisabolol and chamazulene, depends on the plant part, origin and quality of the source, genetic, and environmental factors. Moreover, other parameters, such as season of harvest and methods of extraction, can affect the extraction yield of the essential oils/extracts, their composition and, therefore, their bioactivity. Due to the importance of this genus and particularly M. recutita (M. chamomilla), this review focus on its cultivation, factor affecting essential oils' composition and their role in traditional medicine, as antibacterial agents and finally as food preservatives.

Evolutionary ethnobiology and cultural evolution: opportunities for research and dialog

The interest in theoretical frameworks that improve our understanding of social-ecological systems is growing within the field of ethnobiology. Several evolutionary questions may underlie the relationships between people and the natural resources that are investigated in this field. A new branch of research, known as evolutionary ethnobiology (EE), focuses on these questions and has recently been formally conceptualized. The field of cultural evolution (CE) has significantly contributed to the development of this new field, and it has introduced the Darwinian concepts of variation, competition, and heredity to studies that focus on the dynamics of local knowledge. In this article, we introduce CE as an important theoretical framework for evolutionary ethnobiological research. We present the basic concepts and assumptions of CE, along with the adjustments that are necessary for its application in EE. We discuss different ethnobiological studies in the context of this new framework and the new opportunities for research that exist in this area. We also propose a dialog that includes our findings in the context of cultural evolution.

The taste of heat: How humoral qualities act as a cultural filter for chemosensory properties guiding herbal medicine

ETHNOPHARMACOLOGICAL RELEVANCE

Organoleptic properties, and more specifically chemosensory cues, have been shown to guide therapeutic applications of medicinal plants. Humoral qualities, on the other hand, are widely believed to be an abstract concept, mainly applied post hoc to validate therapy. However, the nexus between humoral qualities, chemosensory properties, and medicinal plant uses has never been systematically assessed.

AIM OF THE STUDY

To systematically analyse the correlations between chemosensory properties, humoral qualities, and medicinal uses of selected botanical drugs.

METHODS

The issue was approached experimentally via an organoleptic testing panel, consisting of Zoque healers in Chiapas, Mexico. The healers smelled and tasted 71 selected herbal drugs and subsequently commented on their humoral qualities and therapeutic uses. The resulting dataset is analysed for correlations between these variables using Bayesian statistics. Qualitative data on the characteristics and role of the hot-cold dichotomy complement the quantitative analysis, facilitating meaningful interpretation.

RESULTS AND DISCUSSION

The results reproduce and extend the findings of previous studies, which established specific correlations between chemosensory cues and nosological units. The key predictors of drugs' therapeutic uses, however, are their humoral qualities, which are themselves conditioned by taste and smell. These findings appear to be valid for drug samples known to the participants as well as for unfamiliar samples. Thus, this study establishes the role of the hot-cold dichotomy as an important cultural filter connecting organoleptic properties and therapeutic uses of herbal drugs.

CONCLUSIONS

There is considerable cross-cultural consensus in Mesoamerica for the specific correlations described in this study. Given the continued pervasiveness of the hot-cold dichotomy, humoral qualities and the underlying organoleptic properties ought to be increasingly considered in the design of pharmaceutical products as well as public health strategies. Such culturally appropriate adjustments may considerably improve the perceived quality and effectiveness of healthcare.

Assessing the Effects of Indigenous Migration on Zootherapeutic Practices in the Semiarid Region of Brazil

Human migration implies adaptations to new environments, such as ways to benefit from the available biodiversity. This study focused on the use of animal-derived remedies, and we investigated the effects of migration on the traditional medical system of the indigenous Truká people. This ethnic group lives in Northeast Brazil and is currently distributed in four distinct villages. In these villages, the zootherapeutic knowledge of 54 indigenous people was determined through semi-structured questionnaires given from September 2013 to January 2014. The interviewees indicated 137 zootherapeutic uses involving 21 animal species. The variety of species and their uses have a higher similarity between villages that are closer to each other, which can be a reflection of geographic and environmental factors. However, even close villages showed a low similarity in the zootherapeutic uses recorded, which reflects a strong idiosyncrasy regarding the knowledge of each village. Hence, each village may be influenced by the physical environment and contact with other cultures, which may maintain or reduce the contact of younger villages with the original village.

Indigenous traditional medicine and intercultural healthcare in Bolivia: a case study from the Potosi region

Indigenous peoples have the worst socio-demographic indicators and the largest inequalities in terms of access to social services and health in the Latin American region, Bolivia included. In the last few years, attempts to implement policies that support indigenous people's health rights led to the development of intercultural health approaches. Yet, acceptance and integration of indigenous medicine into the biomedical health system presents a major challenge to intercultural health in Latin America. The objective of this article is to analyze the case of a health center in Tinguipaya, one of the first and few examples of intercultural health initiatives in Bolivia. This intercultural health project, which represents a pioneer experience with regard to the creation of intercultural health services in Bolivia, aims to create a network between local communities, traditional healers, and biomedical staff and offer a more culturally sensitive and holistic health service for indigenous people living in the area. The aim of this article is to critically assess this initiative and to analyze the main challenges met in the creation of a more effective intercultural health policy. The extent to which this initiative succeeded in promoting the integration between indigenous health practitioners and biomedical staff as well as in improving access to health care for local indigenous patients will also be examined.

A Qualitative Exploration of Less Acculturated Mexican Mothers' Safety Perceptions of Herbs, Medicines, and Cleaners in the Home

Childhood poisoning is a leading public health concern in our society. The death rate from unintentional poisonings among children has increased by 80% from 2000 to 2009. Immigrant children are also at-risk. A qualitative study, consisting of a pile sort, was conducted among immigrant Mexican mothers to determine their safety perceptions of commonly used medicines, herbs, and cleaners. Participants (N = 35) were selected for semi-structured interviews from a pediatric primary care clinic in the Dallas/Fort Worth Metroplex. Some mothers over-estimated their children's ability to discern the dangers of substances, relied heavily on sensory skills of children, and perceived a medicine as safe after successful use in the past. Other mothers were more cognizant of allergic reactions, ingestion, and the need to store substances carefully. Brief interventions that incorporate culturally-appropriate safety messages are needed to assist Mexican mothers in creating a safe home environment.

Ethnomedicine of menstruation in rural Dominica, West Indies

ETHNOPHARMACOLOGICAL RELEVANCE

In Dominica, women offer dysmenorrhea, delayed menses, and menorrhagia as prevalent menstrual troubles. Dominican humoral theory considers menstruation to be "hot" such that menstrual problems are caused by the introduction of too much "cold" in the body. These conditions can be painful and may require herbal medicine. Our method finds the most culturally salient plants for these conditions-those which are of common knowledge across the population. We hypothesize that cultural agreement on ethnobotanical treatments (1) reflects their perceived ethnophysiological efficacy, and that (2) salient plants contain bioactive compounds appropriate for the menstrual conditions for which Dominicans employ the plants.

MATERIALS AND METHODS

Qualitative data on local explanatory models and treatment of menstrual conditions were collected using participant-observation, focus groups, and informal key informant interviews. Quantitative ethnobotanical data come from freelist (or "free-list") tasks, conducted with 54 adults.

RESULTS

Mean salience values calculated from freelisted data reveal that the same four plants, Cinnamomum verum (synonym Cinnamomum zeylanicum) (Lauraceae), Mentha suaveolens (Lamiaceae), Pimenta racemosa (Myrtaceae) and Sphagneticola trilobata (synonym Wedelia trilobata) (Asteraceae) are used to treat dysmenorrhea and delayed menses. The only remedy reported for menorrhagia, Sphagneticola trilobata (Asteraceae), is also a treatment for dysmenorrhea and delayed menses. The Dominican humoral system views menstruation as a "hot" condition, yet these "bush medicines" are also "hot." Dominicans do not view menstruation as a problem, rather, they reckon that excess "cold" in a woman׳s menstruating body impedes menstrual function to cause problems thus requiring "hot" plants to alleviate their symptoms. A literature review revealed that all four plants contain analgesic, anti-nociceptive, and anti-inflammatory properties. Additionally, Mentha suaveolens is muscle-relaxing and anti-spasmodic, Cinnamomum verum has a mild anti-coagulant, and Sphagneticola trilobata has wound healing, anti-stress, and sedative properties.

CONCLUSIONS

In Dominican menstrual problems there is correspondence between cultural consensus, bioactivity, and humoral theory. Examining the ethnophysiology of menstruation and its complications provides evidence for the expectations of actions and effectiveness of locally culturally salient medicinal plants.

Phytotherapy of Polish migrants in Misiones, Argentina: legacy and acquired plant species

ETHNOPHARMACOLOGICAL RELEVANCE

Analyzing how and why phytotherapeutical practices survive a migratory process is important for understanding migrant health seeking behaviour and health demand. Contrary to most studies, which focus on migrants from warm climates who settle in European and American cities, this study explores continuations in the herbal pharmacopoeia of Eastern European peasants who settled down in rural subtropical areas of Argentina. The study also explores the pharmacopoeia among the descendants of the first generation born in Argentina.

MATERIAL AND METHODS

Primary and secondary sources were employed in the study. Data were collected during over 200 interviews (semi-structured, free lists and in-depth) with 94 study participants. Voucher specimens of species mentioned were gathered and identified. Illnesses were reported according to local ethnomedical terminology and classification. Only reports from informants' own experience were included in the analysis. The unit of analysis was a plant use report (plant species × plant part × ailment × informant). The frequency of mentions was calculated for plant parts used and modes of preparation and administration of herbal medicines, and the Informant Diversity Value was also estimated. Secondary information was obtained from ethnobotanical and ethnomedical literature concerning the whole of Poland. A list was made of medicinal plant species known from Poland available in the study area. Then, the similarity between the available species and those used by Polish migrants was evaluated by applying the Simpson index.

RESULTS

An exhaustive list of 129 plant species used by the Polish community in Misiones, Argentina, was obtained. Among 37 species known form Poland and available in Misiones, 19 were used by the community. There was low consensus on the treatment of health conditions with legacy plants between Polish migrants and the Polish folk pharmacopoeia. The reasons for the relatively low use of legacy species are explained. More continuation has been observed in forms of application and administration of medicinal plants. Most of the continued species are food plants and are predominantly applied as medicinal food.

CONCLUSIONS

In the migratory process, Polish peasants have preserved culturally salient species, which have a wide range of therapeutic applications and are easily accessible. Polish migrants and their descendants have incorporated a great number of local medicinal plant species into their home medicine but at the same time retained traditional ways of administration of herbal medicines. Based on the theory of acculturation, the observed patterns of medicinal plant use in Polish migrant colonies in Misiones indicate good adaptation to the predominant cultural environment.

A comparison of traditional food and health strategies among Taiwanese and Chinese immigrants in Atlanta, Georgia, USA

BACKGROUND

Ethnobotanical studies on the use of plants amongst migrant populations are of great relevance to public health. Traditional health strategies, which incorporate plants as medicines, foods, or both - can play an important role in individual well-being. However, at the same time, migrant populations' traditional knowledge of such practices may be under a state of greater threat of decline due to factors such as limited access to the plant materials and physical isolation from the homeland, which serves as the primary living reservoir for this knowledge.

METHODS

In this study, we conducted a medical ethnobotanical survey focusing on a comparison of local medicinal food and health strategies with members of two Asian immigrant populations in metro-Atlanta: Chinese and Taiwanese. Snowball sampling techniques were employed to recruit 83 study participants, 57 of which were included in the final analysis. Semi-structured interview techniques were used to question participants about their beliefs and usage of the yin yang system, usage of Chinese herbs and medicinal foods, preference and usage of Eastern and Western medicines, and gardening for medicinal foods.

RESULTS AND CONCLUSION

Comparison of the two groups demonstrated a remarkable difference in health strategies concerning medicinal plant use, including statistically significant differences in beliefs concerning yin and yang, uses of Eastern versus Western medicine, and gardening for medicinal foods. Domestic health strategies in the form of medicinal foods play an important role in local health practices, especially among the Taiwanese participants. The collective desire for the use of both Eastern and Western medicine by both groups highlights the important role that cultural competency training will play in preparing allopathic health practitioners to serve increasingly diverse patient populations in the US.

Migrant health in New Zealand: exploring issues concerning medicines access and use

Objectives

Every year a cohort of new migrants enters New Zealand (NZ), bringing challenges that impact on medicines use and health outcomes. The prescribing of medicines is a common therapeutic intervention and access to medicines and optimal use cannot be assumed for these populations. Internationally the literature exploring issues relating to medicines access and use by migrants in high-income countries is scarce. This study aims to explore attitudes, beliefs and perceptions of a cohort of migrants about medicines access and use in NZ.

Methods

A qualitative research methodology was employed with participants being recruited through snowballing techniques and interviewed (seven Indian and four Chinese). Following consent, a semi-structured guide was used for discussions. Themes were developed from codes based on the guide. These themes were developed by two members of the research team and reviewed by a third member.

Results

Emergent themes reflected the following dialogue: (a) financial barriers: paying doctor and pharmacist, lack of affordability of over-the-counter medicines, sharing medicines with family and friends; (b) information transfer and knowledge of rules, systems and initiatives, particularly regarding subsidies and brand switching; (c) misconceptions due to culture and language barriers, including not understanding information and lack of compliance in symptom-free disease; (d) perceptions of high quality in prescription medicines; (e) non-disclosure of traditional medicine use and (f) variability of community pharmacy service provision, especially counselling.

Conclusions

Significant barriers to access and optimal use of medicines by new migrants in NZ were identified. Policy change and educational interventions are likely to be required to improve medicines-related health care to migrant New Zealanders. Future research will need to quantify the extent of the issues and interventions should be developed and evaluated as ongoing research.

How do researchers categorize drugs, and how do drug users categorize them?

This paper considers drug classifications and terms widely used in US survey research, and compares these to classifications and terms used by drug users. We begin with a critical review of drug classification systems, including those oriented to public policy and health services as well as survey research. We then consider the results of a pile sort exercise we conducted with 76 respondents within a mixed method study of Southeast Asian American adolescent and young adult drug users in urban Northern California, USA. We included the pile sort to clarify how respondents handled specific terms which we understood to be related to Ecstasy and methamphetamines. Results of the pile sort were analyzed using graphic layout algorithms as well as content analysis of pile labels. Similar to the national surveys, our respondents consistently differentiated Ecstasy terms from methamphetamine terms. We found high agreement between some specific local terms (thizz, crystal) and popular drug terms, while other terms thought to be mainstream (crank, speed) were reported as unknown by many respondents. In labeling piles, respondents created taxonomies based on consumption method (in particular, pill) as well as the social contexts of use. We conclude by proposing that divergences between drug terms utilized in survey research and those used by drug users may reflect two opposing tendencies: the tendency of survey researchers to utilize standardized language that constructs persons and experiences as relatively homogeneous, varying only within measurable degrees, and the tendency of drug users to utilize specialized language (argot) that reflects their understandings of their experiences as hybrid and diverse. The findings problematize the validity of drug terms and categories used in survey research.

Can Andean medicine coexist with biomedical healthcare? A comparison of two rural communities in Peru and Bolivia

BACKGROUND

It is commonly assumed that indigenous medical systems remain strong in developing countries because biomedicine is physically inaccessible or financially not affordable. This paper compares the health-seeking behavior of households from rural Andean communities at a Peruvian and a Bolivian study site. The main research question was whether the increased presence of biomedicine led to a displacement of Andean indigenous medical practices or to coexistence of the two healing traditions.

METHODOLOGY

Open-ended interviews and free listing exercises were conducted between June 2006 and December 2008 with 18 households at each study site. Qualitative identification of households' therapeutic strategies and use of remedies was carried out by means of content analysis of interview transcriptions and inductive interference. Furthermore, a quantitative assessment of the incidence of culture-bound illnesses in local ethnobiological inventories was performed.

RESULTS

Our findings indicate that the health-seeking behavior of the Andean households in this study is independent of the degree of availability of biomedical facilities in terms of quality of services provided, physical accessibility, and financial affordability, except for specific practices such as childbirth. Preference for natural remedies over pharmaceuticals coexists with biomedical healthcare that is both accessible and affordable. Furthermore, our results show that greater access to biomedicine does not lead to less prevalence of Andean indigenous medical knowledge, as represented by the levels of knowledge about culture-bound illnesses.

CONCLUSIONS

The take-home lesson for health policy-makers from this study is that the main obstacle to use of biomedicine in resource-poor rural areas might not be infrastructural or economic alone. Rather, it may lie in lack of sufficient recognition by biomedical practitioners of the value and importance of indigenous medical systems. We propose that the implementation of health care in indigenous communities be designed as a process of joint development of complementary knowledge and practices from indigenous and biomedical health traditions.

Comparative medical ethnobotany of the senegalese community living in turin (northwestern Italy) and in adeane (southern senegal)

A medico-ethnobotanical survey was conducted among the Senegalese migrant communities of Turin (Piedmont, NW Italy) and their peers living in Adeane (Casamance, Southern Senegal), both among healers and laypeople. Through 27 in-depth interviews, 71 medicinal plant taxa were recorded and identified in Adeane and 41 in Turin, for a total of 315 different folk remedies recorded in Senegal and 62 in Turin. The large majority of the medicinal plants recorded among Senegalese migrants in Turin were also used in their country of origin. These findings demonstrate the resilience of home remedies among migrants and consequently the role they should have in shaping public health policies devoted to migrant groups in Western Countries, which seek to seriously take into account culturally sensitive approaches, that is, emic health-seeking strategies.

The use of medicinal plants by migrant people: adaptation, maintenance, and replacement

Given the importance of studying the knowledge, beliefs, and practices of migrant communities to understand the dynamics of plant resource use, we reviewed the scientific literature concerning the use of medicinal plants by migrant populations engaged in international or long-distance migrations. We considered the importance of two processes: (1) adaptation to the new flora of the host country (i.e., substitution and incorporation of plants in the pharmacopoeia) and (2) continued use and acquisition of the original flora from migrants' home countries (i.e., importation, cultivation, and/or continued use of plants that grow in both host and home environments). We suggest that, depending on the specific context and conditions of migration, different processes that determine the use and/or selection of plants as herbal medicines may become predominant.

Folk medicine in the northern coast of Colombia: an overview

BACKGROUND

Traditional remedies are an integral part of Colombian culture. Here we present the results of a three-year study of ethnopharmacology and folk-medicine use among the population of the Atlantic Coast of Colombia, specifically in department of Bolívar. We collected information related to different herbal medicinal uses of the local flora in the treatment of the most common human diseases and health disorders in the area, and determined the relative importance of the species surveyed.

METHODS

Data on the use of medicinal plants were collected using structured interviews and through observations and conversations with local communities. A total of 1225 participants were interviewed.

RESULTS

Approximately 30 uses were reported for plants in traditional medicine. The plant species with the highest fidelity level (Fl) were Crescentia cujete L. (flu), Eucalyptus globulus Labill. (flu and cough), Euphorbia tithymaloides L. (inflammation), Gliricidia_sepium_(Jacq.) Kunth (pruritic ailments), Heliotropium indicum L. (intestinal parasites) Malachra alceifolia Jacq. (inflammation), Matricaria chamomilla L. (colic) Mentha sativa L. (nervousness), Momordica charantia L. (intestinal parasites), Origanum vulgare L. (earache), Plantago major L. (inflammation) and Terminalia catappa L. (inflammation). The most frequent ailments reported were skin affections, inflammation of the respiratory tract, and gastro-intestinal disorders. The majority of the remedies were prepared from freshly collected plant material from the wild and from a single species only. The preparation of remedies included boiling infusions, extraction of fresh or dry whole plants, leaves, flowers, roots, fruits, and seeds. The parts of the plants most frequently used were the leaves. In this study were identified 39 plant species, which belong to 26 families. There was a high degree of consensus from informants on the medical indications of the different species.

CONCLUSIONS

This study presents new research efforts and perspectives on the search for new drugs based on local uses of medicinal plants. It also sheds light on the dependence of rural communities in Colombia on medicinal plants.

The future is written: impact of scripts on the cognition, selection, knowledge and transmission of medicinal plant use and its implications for ethnobotany and ethnopharmacology

AIM OF THE STUDY

Apart from empirically learned medicinal and pharmacological properties, the selection of medicinal plants is dependent on cognitive features, ecological factors and cultural history. In literate societies the transmission of medicinal plant knowledge through texts and, more recently, other media containing local as well as non-local knowledge has a more immediate and a more prolonged effect than oral transmission. Therefore, I try to visualize how field based studies in ethnobiology and especially medical ethnobotany and ethnopharmacology run the risk of repeating information and knowledge and illustrate the importance of differentiating and acknowledging the origin, transmission and rationale of plant use made by humans.

MATERIALS AND METHODS

Reviewing literature dealing with the traditional parameters (e.g. hot/cold dichotomy, organoleptic properties, doctrine of signatures) influencing the selection and transmission of plant use in a juxtaposition to our recent finding of causal influence of text on local plant use. Discussing the passing down of knowledge by text as a special case of oblique/one-to-many knowledge transmission.

RESULTS

Historical texts on materia medica, popular books on plant use, clinical studies, and informants of ethnobotanical field studies generate a circle of information and knowledge, which progressively conditions the results of ethnobotanical field studies. While text reporting on phytotherapeutical trends may cause innovation through the introduction of "new" applications to local customs, persistently repeating well established folk remedies leads to the consolidation of such uses adding a conservative dimension to a local pharmacopoeia, which might not actually be there to that extent.

CONCLUSIONS

Such a "shaping" of what might appear to be the results of a field investigation is clearly outside the ordinary principles of scientific enquiry. The traditional pillars of ethnobotanical field studies - that is, "input to drug discovery" and "conservation of cultural heritage" - are also incompatible with this process. Ethnobotancial field studies aimed at a contribution to natural products research and/or the conservation of cultural heritage, as well as those aimed at an assessment and validation of local pharmacopoeias should differentiate between local plant use and widespread as well as modern knowledge reported in popular textbooks and scientific literature.

Ethnopharmacological survey among migrants living in the Southeast Atlantic Forest of Diadema, São Paulo, Brazil

BACKGROUND

Understanding how people of diverse cultural backgrounds have traditionally used plants and animals as medicinal substances during displacements is one of the most important objectives of ethnopharmacological studies. An ethnopharmacological survey conducted among migrants living in the Southeast Atlantic Forest remnants (Diadema, São Paulo, Brazil) is presented herein.

METHODS

Ethnographical methods were used to select and interview the migrants, and botanical and zoological techniques were employed to collect the indicated resources.

RESULTS

We interviewed five migrants who described knowledge on 12 animals and 85 plants. Only 78 plants were present in Diadema, they belong to 37 taxonomic families; 68 were used exclusively for medicinal purposes, whereas 10 were reported to be toxic and/or presented some restriction of use. These taxa were grouped into 12 therapeutic categories (e.g., gastrointestinal disturbances, inflammatory processes or respiratory problems) based on the 41 individual complaints cited by the migrants. While the twelve animal species were used by the migrants to treat nine complaints; these were divided into six categories, the largest of which related to respiratory problems. None of the animal species and only 57 of the 78 plant species analysed in the present study were previously reported in the pharmacological literature; the popular knowledge concurred with academic findings for 30 of the plants. The seven plants [Impatiens hawkeri W. Bull., Artemisia canphorata Vill., Equisetum arvensis L., Senna pendula (Humb. & Bonpl. ex Willd.) H.S. Irwin & Barneby, Zea mays L., Fevillea passiflora Vell. and Croton fuscescens Spreng)] and the two animals (Atta sexdens and Periplaneta americana) that showed maintenance of use among migrants during their displacement in Brazilian territory, have not been studied by pharmacologists yet.

CONCLUSIONS

Thus, they should be highlighted and focused in further pharmacology and phytochemical studies, since the persistence of their uses can be indicative of bioactive potentials.

Popular medicine and self-care in a Mexican migrant community: toward an explanation of an epidemiological paradox

While Hispanics are among the most economically disadvantaged groups in the United States, immigrants from Latin America have health profiles equal to or better than Americans of European descent. Research on this epidemiological paradox suggests that aspects of Hispanic culture prevent negative health outcomes associated with poverty, poor education, and barriers to professional care. However, little attention has been given to the ethnomedical beliefs and practices of any Hispanic subgroup. Here I present an ethnographic study of women's popular medicine in a Mexican migrant community in Athens, Georgia. Migrant women promote healthy behaviors, diagnose sick family members, and prescribe home remedies. These practices stem from long traditions of self-medication and family care, which have experienced less disruption by the biomedical profession than have other North American popular medical systems. Examining Mexican popular medicine within the context of scientific literature suggests that these self-care practices protect health and should be considered by investigators of the "Hispanic health paradox." The study also suggests that directing more attention to self-care will be fruitful for medical anthropology.

Alpine ethnobotany in Italy: traditional knowledge of gastronomic and medicinal plants among the Occitans of the upper Varaita valley, Piedmont

A gastronomic and medical ethnobotanical study was conducted among the Occitan communities living in Blins/Bellino and Chianale, in the upper Val Varaita, in the Piedmontese Alps, North-Western Italy, and the traditional uses of 88 botanical taxa were recorded. Comparisons with and analysis of other ethnobotanical studies previously carried out in other Piemontese and surrounding areas, show that approximately one fourth of the botanical taxa quoted in this survey are also known in other surrounding Occitan valleys. It is also evident that traditional knowledge in the Varaita valley has been heavily eroded. This study also examined the local legal framework for the gathering of botanical taxa, and the potential utilization of the most quoted medicinal and food wild herbs in the local market, and suggests that the continuing widespread local collection from the wild of the aerial parts of Alpine wormwood for preparing liquors (Artemisia genipi, A. glacialis, and A. umbelliformis) should be seriously reconsidered in terms of sustainability, given the limited availability of these species, even though their collection is culturally salient in the entire study area.

Xki yoma' (our medicine) and xki tienda (patent medicine)--interface between traditional and modern medicine among the Mazatecs of Oaxaca, Mexico

OBJECTIVES

Little is known about the interface of traditional (generally plant based) medicines and of commercially available pharmaceutical (and related) products. Here we provide a case study to understand how and to what extent traditional and modern medicine have been integrated in an indigenous community and whether these two categories offer a meaningful model for understanding medicine selection. Consequently, this paper explores the use and knowledge of medicinal plants and patent medicines among laypeople living in a rural Mazatec indigenous community in Oaxaca, Mexico.

METHODS

This paper is based on field study over a period of approximately 20 months using participant observation, unstructured and structured interviews including freelisting. The medicinal plant species and commercially available pharmaceuticals were assessed using published biomedical information.

MAIN OUTCOMES

The local ethnopharmacopoeias, emic concepts of illness, epidemiology, and case studies on therapeutic choice were documented. We found that self-treatment is the most common first therapeutic choice. Many of the plant species used by Mazatecs have recognized therapeutic properties, in some cases in vivo and in vitro studies point to well defined pharmacological effects, and in a few cases clinical evidence is available. Likewise, people commonly use patent medicines that are effective in the treatment of the most common health conditions. However, we also documented the medicinal use of some toxic plant species (Aristolochia spp.) and of some patent medicines that are held to be unsafe in developed countries (sodium metamizole).

CONCLUSIONS

When looking at a complex pluralistic medical system an approach that goes beyond the externally imposed dichotomic categories of traditional and modern medicine can be very useful to shed light on other dimensions that underlie the local use of medicines. With the increasing integration of the Mazatecs with the outside world, the concomitant use of both types of resources is constantly changing and helps the Mazatecs in their struggle for health.

Cross-cultural adaptation in urban ethnobotany: the Colombian folk pharmacopoeia in London

AIM OF THE STUDY

To investigate traditional health care practices and changes in medicinal plant use among the growing Colombian community in London.

MATERIALS AND METHODS

Ethnobotanical fieldwork consisted of qualitative, in-depth, semi-structured interviews with 23 Colombians living in London and botanical identification of 46 plant species actively used as herbal remedies. Subsequently, research data were compared with literature on ethnobotany and traditional herbal medicine in the home country, using a framework on cross-cultural adaptation, adjusted for the purpose of this study.

RESULTS

Similarities and discrepancies between data and literature are interpreted as potential indicators of continuity and loss (or deculturation) of traditional remedies, respectively. Remedies used in London that are not corroborated by the literature suggest possible newly acquired uses.

CONCLUSIONS

Cross-cultural adaptation related to health care practices is a multifaceted process. Persistence, loss and incorporation of remedies into the Colombian folk pharmacopoeia after migration are influenced by practical adaptation strategies as well as by symbolic-cultural motives of ethnic identity.

The use of the pile sort method in identifying groups of healthful lifestyle behaviors among female community college students

When encountering new or understudied populations, it is useful to build an understanding of the needs and perceptions of the target audience. This study investigated the application of the qualitative pile sort method for gaining information about nutrition and physical activity behaviors. In a pile sort, individuals make a list of topics relevant to a particular subject, and then they group these topics into related piles. This study investigated whether there was consistency in the ways in which participants grouped behaviors related to having a healthful lifestyle. Pile sorts were conducted during six focus groups among 28 female community college students (46% white; 39% had a 2-year degree or higher). A total of 74 piles of grouped behaviors were coded from the transcripts. Analyses revealed good consistency (identified nine to 12 times) for four groupings: exercise, lifestyle, how you eat, and positive foods. The pile sort method represents an activity that can be incorporated into formative research for interventions focused on complex behaviors with multiple components; in addition, this method may provide structure to counseling sessions and facilitate a better understanding of the perceptions of healthful eating and physical activity from patients' perspectives.

Medicinal perceptions of vegetables traditionally consumed by South-Asian migrants living in Bradford, Northern England

Dietary habits change rapidly amongst migrant communities in Western countries, and these changes can cause major concerns for public-health policymakers because they frequently lead to increases in diet-related diseases like diabetes. Such is the case in most South-Asian communities in the UK. In this study, we carried out an ethnobiological survey of the vegetables traditionally consumed among the Indian and Pakistani communities of Bradford, in Western Yorkshire, UK. Our purpose was to analyse in depth details of the traditional culinary use of vegetables within these households, and to assess the health perceptions of them. Semi-structured interviews with a total of 150 South-Asian women were carried out. Twenty-five vegetables were recorded, as well as their traditional culinary use and their frequency of use. We found that a few of these vegetables, particularly those presenting bitter or aromatic tastes, were perceived to have remarkable medicinal value particularly against diabetes. Our study also found important generational differences in the women's knowledge of the culinary processes related to these foods, confirming that the consumption of traditional vegetables is inextricably embedded in cultural heritage and the representation of identity among migrants. Our findings may offer evidence of a link between the choice of food and the foods' perceived medicinal value among South-Asian migrants. It may also provide important information for health care professionals when designing strategies for improving health care counteracting type 2 diabetes. We strongly believe such strategies should take into account socio-cultural components and emic health beliefs, as well as patients' views of traditional dietary ingredients.

Does the taste matter? Taste and medicinal perceptions associated with five selected herbal drugs among three ethnic groups in West Yorkshire, Northern England

In recent years, diverse scholars have addressed the issue of the chemosensory perceptions associated with traditional medicines, nevertheless there is still a distinct lack of studies grounded in the social sciences and conducted from a cross-cultural, comparative perspective. In this urban ethnobotanical field study, 254 informants belonging to the Gujarati, Kashmiri and English ethnic groups and living in Western Yorkshire in Northern England were interviewed about the relationship between taste and medicinal perceptions of five herbal drugs, which were selected during a preliminary study. The herbal drugs included cinnamon (the dried bark of Cinnamomum verum, Lauraceae), mint (the leaves of Mentha spp., Lamiaceae), garlic (the bulbs of Allium sativum, Alliaceae), ginger (the rhizome of Zingiber officinale, Zingiberaceae), and cloves (the dried flower buds of Syzygium aromaticum, Myrtaceae). The main cross-cultural differences in taste perceptions regarded the perception the perception of the spicy taste of ginger, garlic, and cinnamon, of the bitter taste of ginger, the sweet taste of mint, and of the sour taste of garlic. The part of the study of how the five selected herbal drugs are perceived medicinally showed that TK (Traditional Knowledge) is widespread among Kashmiris, but not so prevalent among the Gujarati and especially the English samples. Among Kashmiris, ginger was frequently considered to be helpful for healing infections and muscular-skeletal and digestive disorders, mint was chosen for healing digestive and respiratory troubles, garlic for blood system disorders, and cinnamon was perceived to be efficacious for infectious diseases. Among the Gujarati and Kashmiri groups there was evidence of a strong link between the bitter and spicy tastes of ginger, garlic, cloves, and cinnamon and their perceived medicinal properties, whereas there was a far less obvious link between the sweet taste of mint and cinnamon and their perceived medicinal properties, although the link did exist among some members of the Gujarati group. Data presented in this study show how that links between taste perceptions and medicinal uses of herbal drugs may be understood as bio-cultural phenomena rooted in human physiology, but also constructed through individual experiences and culture, and that these links can therefore be quite different across diverse cultures.
