Caribbean medicinal plant Argemone mexicana L.: Metabolomic analysis and in vitro effect on the vaginal microbiota

ETHNOPHARMACOLOGICAL RELEVANCE

Medicinal plants are frequently used in Caribbean traditional medicine as low-cost, culturally relevant treatments for women's health concerns, such as gynecological infections. These plants are typically applied topically, potentially affecting both pathogenic bacteria (e.g., Gardnerella vaginalis) and beneficial vaginal microbes (Lactobacillus spp.). However, few studies have examined the impact of these plants on both beneficial and pathogenic vaginal bacteria.

AIM OF THE STUDY

Argemone mexicana, available in New York City and commonly used to treat gynecological infections by immigrants from the Dominican Republic, was investigated for its chemical variation and effects on the vaginal microbiota. We hypothesized that variations in the bioactivity of Argemone mexicana on Gardnerella vaginalis and Lactobacillus spp. are due to differences in antimicrobial compounds across different preparations.

MATERIALS AND METHODS

Untargeted and targeted metabolomic analysis using UPLC-qToF-MS and UPLC-TQD-MS were conducted on Argemone mexicana samples collected in New York City. Antimicrobial assays were used to assess the effects of Argemone mexicana samples on beneficial and pathogenic vaginal bacteria. ProGenesis QI and EZinfo were used for metabolomic analysis to link bioactivity with chemometric data.

RESULTS

UPLC-qToF-MS and statistical analyses showed that chemical variation correlated with plant tissue type and processing (dry or fresh samples). These differences were evident in antimicrobial screenings, where active plant samples were antimicrobial against pathogenic bacteria only, with no effect on beneficial Lactobacillus. Known antimicrobial benzoquinone alkaloids, such as berberine, were partly responsible for the observed microbiological activity. Berberine exhibited similar inhibition patterns, reduced biofilm formation, and trended towards higher concentration in active samples.

CONCLUSIONS

Extracts of Argemone mexicana, a plant used in Caribbean women's health, did not have an effect on beneficial vaginal microbes, but did inhibit pathogenic Gardnerella vaginalis. This antimicrobial activity correlated with the chemical variation of berberine and other related alkaloids across traditional preparations of Argemone mexicana. These results may be relevant for treating gynecological infections, not only with this plant, but other berberine-containing taxa.

The Folkloric Practices of Dominican Women in Managing Bacterial Vaginosis

Bacterial vaginosis (BV) is characterized by changes in the vaginal flora caused by an elevated pH, resulting in symptoms of vaginal discharge, odor, and irritation. BV affects all women, including Dominican women who have specific cultural beliefs regarding vaginal health hygiene. Due to the prevalence of this condition and cultural norms that may influence how women respond to the diagnosis of BV, it is important to understand the factors that may promote the development of BV and that may influence women's choices of treatment options. Amsel's criteria are the most commonly used clinical approach for the diagnosis of BV. Recurrent BV is common and affects women's lives to varying degrees. Discussion about cultural norms and hygienic practices may provide information that may decrease the recurrence of BV. Nurses can provide support and evidence-based information in a culturally sensitive manner to help Dominican women manage BV.

Haitian women in New York City use global food plants for women's health

BACKGROUND

Despite the availability of mainstream biomedical healthcare in New York City (NYC), community-based ethnomedicine practices remain a low-cost, culturally relevant treatment for many immigrants. Previous urban ethnobotany research in NYC has established that several Caribbean communities continue using medicinal plants for women's health after immigration. This study sought to address to what extent: (1) NYC Haitian women continue using medicinal plants for women's health after migration; (2) their plants and the conditions treated were similar to those identified in an earlier survey with NYC immigrants from the Dominican Republic.

METHODS

Through an ethnobotanical survey, 100 Haitian women living in NYC and born in Haiti were interviewed about their knowledge of medicinal plants for women's health conditions. Reported species were purchased based on local names in NYC Haitian stores and markets, vouchered, and identified.

RESULTS

Nearly all Haitian women (97%) reported using medicinal plants while living in Haiti. Most Haitian women continued using medicinal plants after coming to the USA (83%). The 14% decrease, although significant (z = 3.3; p = 0.001), was mainly due to logistical difficulties with sourcing plants after recent immigration. Popular medicinal plant species reported were primarily global food plants, re-emphasizing the intertwined food-medicine relationship in Caribbean diasporas. Comparison with data from NYC Dominicans identified childbirth and puerperium, gynecological infections, and vaginal cleansing as priority Haitian women's health concerns treated with plants.

CONCLUSION

Our findings support the global nature of Caribbean migrant plant pharmacopeia, predominantly centered around food plants and adapted to transnational urban settings. They underscore cultural diversity, dispelling the notion of one uniform traditional knowledge system labeled "Caribbean." The importance of preventative medicine for women's health, particularly the regular consumption of "healthy" foods or teas highlights the role food plants play in maintaining health without seeking treatment for a particular condition. Cross-cultural comparisons with other NYC Caribbean immigrants emphasize the importance of conducting ethnobotanical surveys to ground-truth plant use in the community. Such surveys can also identify culture-specific health priorities treated with these plants. Healthcare providers can leverage these insights to formulate culturally relevant and community-tailored healthcare strategies aligned with Haitian women's health beliefs and needs.

Local and traditional knowledge systems, resistance, and socioenvironmental justice

In this essay, for the debate series of Journal of Ethnobiology and Ethnomedicine, I argue against the oversimplified causal argument that the maintenance of local and traditional knowledge systems is related to less advantaged circumstances. This statement is based on a colonialist perspective of what a less advantageous circumstance is, which is being questioned by several authors. It also ignores the struggles and resistance of traditional knowledge holders and the urgent call for socioenvironmental justice. As an ethnobiologist, I argue that we must face this reality to build science with justice and inclusiveness.

Women's wellness in the mountains: An exploration of medicinal plants among tibeto-burman groups in Thailand

Ethnopharmacological relevance

This study offers valuable insight into the traditional healing practices of women's healthcare within four Tibeto-Burman groups. By focusing on women's wellness, the research sheds light on the often-neglected yet significant contributions made by women in the field of traditional medicine.

Aims of the study

The study seeks to address the gap of studies on the ethnobotany of women healthcare of the Tibeto-Burman groups in Thailand and to analyst the factors that could affect the diversity of ethnobotanical knowledge.

Materials and methods

The study compiled data from 15 group-informants residing in 12 different villages. The information gathering process involved a combination of free-listing, semi-structured interviews, group discussion, and the walk-to-the-wood method. To analyze the data, the researchers used various methods such as use-reports, Relative Frequency of Citation (RFC), Relative Importance Index (RI), and Cluster analysis.

Results

This study identified 200 plant species used in traditional women's healthcare practices, with leaves being the most frequently used part. Drinking was the most common method for internal use, while bathing and steam were the most emphasized for external use. Blumea balsamifera and Buddleja asiatica had high RI and RFC. Cluster analysis revealed that group-informants were divided by ethnicity and geographical location.

Conclusion

This study contributes to the understanding of traditional healthcare practices among Tibeto-Burman groups in Thailand, with a particular focus on women's wellness. The results provide insight into the ethnobotanical knowledge of these communities and highlight the important role played by women in traditional medicine. The study underscores the need for continued research in this field to preserve and utilize this valuable knowledge.

[Andean women: Attitudes towards the use of plants for the treatment of gynecological eventsMulheres andinas: atitudes em relajo ao uso de plantas para o tratamento de eventos ginecológicos]

Introduction

Diseases often represent physiological changes that require immediate action depending on the severity. Faced with these changes, Andean women put into practice their ancestral knowledge and attitudes to find a solution, as they are the most immediate means at their disposal.

Objective

To interpret the attitudes of Andean women in the province of Hualgayoc, Peru, towards using plants for treating some gynecological events.

Materials and Methods

A qualitative, exploratory, hermeneutic phenomenological design study was conducted with 16 Andean women through a semi-structured interview based on an interview guide with optimal content validity. The results emerged from open, axial, and selective coding and were organized into subcategories and categories.

Results

The categories obtained were favorable attitudes towards using plants and gynecological situations for using plants. The subcategories include satisfaction with the results achieved, safety to continue using plants, aptitude to advise on the use of plants, knowledge of plant's therapeutic effects, events for using plants, and methods of preparing them.

Discussion

Several international studies converge on similar attitudes, manifested in greater trust in traditional medicine, favorable acceptance behavior, belief in its effects, a mental projection of getting well, and willingness to continue its use.

Conclusion

The women were satisfied with the results obtained from the use of medicinal plants because they were beneficial, indigenous to their region, and did not involve any expense. The frequent use of plants was to alleviate pain during menstruation, vaginal infections, and labor.
