Healthcare providers' role regarding the safe and appropriate use of herbal products by breastfeeding mothers: A systematic literature review

Attitudes and counselling of healthcare professionals on increasing breast milk: cross-sectional study

OBJECTIVE

To determine the breast milk-increasing practices healthcare professionals used with their children and their recommendations to mothers.

METHOD

A descriptive cross-sectional study in a Mediterranean region of Turkey. It was carried out with 301 healthcare professionals working in 64 Family Health Centers between January and June 2018. The data were collected by the researchers with a questionnaire including 28 questions.

RESULTS

The mean age of healthcare professionals was 36.89 ± 8.5. All the healthcare professionals encountered mothers with the perception of insufficient breast milk. 73.7% of those with children had breast milk-increasing practices. Increased age negatively affected these practices (OR: 0.923), and increased education positively affected the practices (OR: 3.489). Having received training on breastfeeding and breast milk-increasing measures positively affected the use of practices (OR: 2.118). The use of breast milk-increasing practices by healthcare professionals positively affected their recommendations to mothers (OR: 2.506).

CONCLUSIONS

Health professionals had their own breast milk boosting practices that they recommended to women as well. This result is especially significant in terms of guiding mothers who wish to increase breast milk supply and seek reliable information and contributes to the protection of maternal and newborn health.

Towards defining and supporting pharmacists' professional role associated with traditional and complementary medicines - A systematic literature review

BACKGROUND

A review conducted in 2015 reported community pharmacists are willing to adopt a professional role in counselling consumers about the appropriate and safe use of traditional and complementary medicines (T&CM) but faced multiple barriers in doing so; including the role being poorly defined. This current review aimed to update and extend these findings, by identifying studies published since 2015 that reported on pharmacists across any setting.

METHODS

Eligible studies published between January 01, 2016 and December 31, 2021 were identified across six databases (PubMed, Scopus, Web of Science, EMBASE, ScienceDirect and MEDLINE). A grounded theory approach was used to thematically synthesize the data extracted.

FINDINGS

A total 64 studies representing pharmacists across 30 countries were included for review. Study designs varied including cross-sectional surveys (n = 36), qualitative studies (n = 14), and pseudo-patient studies (n = 3). Eight studies reported on practice and/or bioethical responsibilities and 19 studies reported on factors that would enable pharmacists to fulfill these responsibilities, while 37 studies reported about both.

CONCLUSION

These findings indicate research about pharmacists' responsibilities associated with T&CM is evolving from gap analysis towards research that is proactive in advocating for change in multiple areas. These findings can be used to inform a consensus discussion among pharmacists and key stakeholders regarding a set of professional responsibilities that would serve in the development of: a clearly defined role and associated practice standards, and competency requirements that inform educational learning objectives for inclusion in undergraduate, post-graduate and continuing professional pharmacy education.

Use of Herbal Medicines Among Breastfeeding Mothers in Tanzania: A Cross-Sectional Study

Background: There are limited data on the use of herbal medicines (HM) among breastfeeding mothers, despite the fact that knowledge of the possible benefits or harms of HM use has a direct relationship with the health of infants, especially in resource-limited countries. The study aims to determine the prevalence and factors associated with HM use among breastfeeding mothers in Tanzania. Methods: The study followed a cross-sectional design using a structured survey questionnaire. Survey participants were recruited from the reproductive and child health clinic at Uhuru health center in Morogoro, Tanzania. The survey instrument comprised of 34 questions, including demographic information, the pattern of HM use during breastfeeding, and women's perceptions of HM. Chi-square test and logistic regression were used for data analysis using SPSS ver. 24.0. Results: The majority of the respondents (53.8%) used HM during breastfeeding. The most commonly used HM was black pepper (Piper nigrum L.; 80.0%), followed by pumpkin seeds (Cucurbita pepo L.; 18.0%). About one-third (27.5%) of HM users discussed their use with their healthcare providers. In addition, higher education levels and low breastmilk supply were identified as potential predictors of HM use. Conclusion: The practice of HM use among breastfeeding mothers in Tanzania is popular to ease breastfeeding difficulties. However, the issue of the safety or effectiveness of HM is still an unknown agenda. This awakens the need to evaluate HM's safety, efficacy, and quality through pharmacological studies for scientific evidence. Lastly, a clinical guideline should be developed in healthcare settings to promote open dialogues between the healthcare providers and mothers to ensure the safe use of HM.

Prevalence and the Determinants of Traditional, Complementary, and Integrative Medicine Use Among Breastfeeding Mothers: A Cross-Sectional Study

Objectives: Breastfeeding is highly important for a child's health, and the widespread use of herbal medicines as galactagogues has been reported. The present study was conducted to evaluate the use of traditional, complementary, and integrative medicine (TCIM) and its determinants among breastfeeding mothers in Shiraz, Iran. Design: Cross-sectional study. Setting/Location: Neonatal clinics affiliated to Shiraz University of Medical Sciences. Subjects: Mothers elder than 18 years old. Interventions: Nothing. Outcome Measures: Prevalence and of the use of TCIM products and its associated factors. Methods: In this cross-sectional study, mothers older than 18 years who referred to neonatal clinics affiliated to Shiraz University of Medical Sciences were enrolled. Using a structured interview, the authors explored the prevalence and of the use of TCIM products and its associated factors. Results: Of 625 mothers who were approached, 483 agreed to participate (response rate: 77.3%). The average age was 27.3 ± 5.9 years. The prevalence of using TCIM products during current breastfeeding was 97.1%. There were 168 working mothers (44.9%); 163 mothers (34.1%) complaining of postpartum breastfeeding problems, and 327 mothers (68%) had no history of breastfeeding. Recommendations of medical staff or relatives were the most frequent reasons for the consumption of TCIM products (64.9%). Only 27% of mothers disclosed the use of TCIM products to their doctor or health care provider, although 62% of mothers were asked about the use of such products. Notably, 438 mothers (95.8%) considered TCIM to increase their milk. Based on multivariable logistic regression, literacy and past use of TCIM galactagogues were independently associated with TCIM products use. Conclusions: The use of TCIM galactagogues is highly common among breastfeeding mothers in south of Iran, showing a diverse range of determinants. It is necessary to evaluate the safety and efficacy of common herbal galactagogues, and evidence-based studies must be designed to achieve standardized complementary medicine approaches in this regard.

Traditional plant use during lactation and postpartum recovery: Infant development and maternal health roles

ETHNOPHARMACOLOGICAL RELEVANCE

Evidence of phytochemical roles in infant development and maternal recovery offers insights into beneficial functions of traditional plant use during lactation and the postpartum period. Ethnopharmacological research has relevance to global priorities on maternal and child health, to understanding origins and determinants of human self-medication, and for reconciling traditional postpartum practices and mainstream healthcare.

AIM OF THE STUDY

Present emerging evidence, within evolutionary and socio-cultural contexts, on the role of maternal consumption on transfer of phytochemicals into breast milk with impacts on maternal and child health, and on infant development. Establish current state of knowledge and an ethnopharmacological research agenda that is attentive to cross-cultural and regional differences in postpartum plant use.

MATERIALS AND METHODS

An extensive literature review using Medline, Scopus, and Web of Science focused on traditional and contemporary use and socio-cultural context, as well as physiological, pharmacological, toxicological, and behavioral activities of plants used medicinally by women during postpartum recovery and lactation.

RESULTS

The most widely reported postpartum plants show antimicrobial, anti-inflammatory, immunological, and neurophysiological activities, with low toxicity. Phytochemicals transfer from maternal consumption into breast milk in physiological concentrations, while animal studies demonstrate immunomodulation and other actions of medicinal plants during lactation. Reporting on the use and diverse traditional knowledge of women about plants during the postpartum period is obscured by the marginal place of obstetric issues and by gender biases in ethnobotanical research. In many contemporary contexts use is prejudiced by precautionary risk warnings in health literature and practice that confound lactation with pregnancy.

CONCLUSIONS

Although systematic investigation of postpartum plant use is lacking, known pharmacological activities support potential benefits on infant development and maternal health with immediate and long-term consequences in relation to allergic, inflammatory, autoimmune, and other diseases. An ethnopharmacological agenda focused on the perinatal period requires directed methodologies and a regional approach in relation to culturally-specific knowledge and practices, traditional plant use, and local health needs. Testing the hypothesis that phytochemicals transferred from medicinal plants into breast milk impact the human immune system and other aspects of infant development requires extended analysis of phytochemicals in human milk and infant lumen and plasma, as well as effects on gastrointestinal and milk microbiome.

Predictors of self-medication with herbal remedies during pregnancy based on the theory of planned behavior in Kashan, Iran

BACKGROUND

The incidence of application of medicinal herbs during pregnancy has increased significantly among women over the past years; however, the safety and efficacy of medicinal herbs during pregnancy are still unclear. The aim of the present study was to categorize the predictors of self-medication with herbal remedies during pregnancy based on the theory of planned behavior (TPB).

METHODS

The present descriptive-analytical study was conducted on 300 pregnant women referred to Kashan health center to receive prenatal care services in 2020. The study participants were randomly selected using stratified random sampling with proportional allocation. The data collection tool was a two-part researcher made questionnaire. The first part of the questionnaire included demographic information, midwifery information, and questions related to women's awareness about herbal medicine. The second part of the questionnaire was designed based on the theory of planned behavior including attitudes, perceived behavioral control, subjective norms, intention, and behavior performance. Data were analyzed using descriptive statistics, regression analysis, and SPSS version 18.0.

RESULTS

The mean age of participants was 28. 7±5.4 years (range, 15-45 years), the majority were housewives (88.3%) and had secondary education (39.3%). A total of 164 women (57. 1%) used medicinal herbs during pregnancy. The individual's attitude towards herbal medicines consumption, subjective norm, and perceived behavioral control was correlated with behavioral intention (P < 0.05). Similarly, subjective norms were the most predictor of using herbal medicine among pregnant women (P < 0.05).

CONCLUSION

The findings revealed that more than 50 % of pregnant women used medicinal herbs during pregnancy. The present study showed that the individual's attitude towards herbal medicines consumption, subjective norm, and perceived behavioral control was correlated with intention of herbal medicine use among pregnant women. Likewise, subjective norms were the most predictor of herbal medicine use among pregnant women. The TPB should be addressed in planning health education programs and modifying health behaviors, including self-medication, especially during pregnancy.

How does scientific information reach the consumer? A case study among students into providing verbal information on dietary supplements at point of purchase

Consumers of dietary supplements should be made aware of the benefits and risks of these products. This case study therefore aimed to identify the content of the risk-benefit information provided during the purchase of St. John's wort supplements and how consumers perceive this information. Fifteen participants visited a shop to purchase St. John's wort supplements after which they were interviewed on the provided information during the visit. This case study shows that the spontaneous information provision is not consistent in Dutch drugstores and health food shops. The provided information was either very detailed, or no information was given at all. The perceived reliability of information was mainly determined by the authority of the employee and the type of shop where the product was purchased. Information consistency at the moment of purchase is of influence in the perceived value of it.

Oral galactagogues (natural therapies or drugs) for increasing breast milk production in mothers of non-hospitalised term infants

BACKGROUND

Many women express concern about their ability to produce enough milk, and insufficient milk is frequently cited as the reason for supplementation and early termination of breastfeeding. When addressing this concern, it is important first to consider the influence of maternal and neonatal health, infant suck, proper latch, and feeding frequency on milk production, and that steps be taken to correct or compensate for any contributing issues. Oral galactagogues are substances that stimulate milk production. They may be pharmacological or non-pharmacological (natural). Natural galactagogues are usually botanical or other food agents. The choice between pharmacological or natural galactagogues is often influenced by familiarity and local customs. Evidence for the possible benefits and harms of galactagogues is important for making an informed decision on their use.

OBJECTIVES

To assess the effect of oral galactagogues for increasing milk production in non-hospitalised breastfeeding mother-term infant pairs.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register, ClinicalTrials.gov, the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP), Health Research and Development Network - Phillippines (HERDIN), Natural Products Alert (Napralert), the personal reference collection of author LM, and reference lists of retrieved studies (4 November 2019).

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and quasi-RCTs (including published abstracts) comparing oral galactagogues with placebo, no treatment, or another oral galactagogue in mothers breastfeeding healthy term infants. We also included cluster-randomised trials but excluded cross-over trials.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane Pregnancy and Childbirth methods for data collection and analysis. Two to four review authors independently selected the studies, assessed the risk of bias, extracted data for analysis and checked accuracy. Where necessary, we contacted the study authors for clarification.

MAIN RESULTS

Forty-one RCTs involving 3005 mothers and 3006 infants from at least 17 countries met the inclusion criteria. Studies were conducted either in hospitals immediately postpartum or in the community. There was considerable variation in mothers, particularly in parity and whether or not they had lactation insufficiency. Infants' ages at commencement of the studies ranged from newborn to 6 months. The overall certainty of evidence was low to very low because of high risk of biases (mainly due to lack of blinding), substantial clinical and statistical heterogeneity, and imprecision of measurements. Pharmacological galactagogues Nine studies compared a pharmacological galactagogue (domperidone, metoclopramide, sulpiride, thyrotropin-releasing hormone) with placebo or no treatment. The primary outcome of proportion of mothers who continued breastfeeding at 3, 4 and 6 months was not reported. Only one study (metoclopramide) reported on the outcome of infant weight, finding little or no difference (mean difference (MD) 23.0 grams, 95% confidence interval (CI) -47.71 to 93.71; 1 study, 20 participants; low-certainty evidence). Three studies (metoclopramide, domperidone, sulpiride) reported on milk volume, finding pharmacological galactagogues may increase milk volume (MD 63.82 mL, 95% CI 25.91 to 101.72; I² = 34%; 3 studies, 151 participants; low-certainty evidence). Subgroup analysis indicates there may be increased milk volume with each drug, but with varying CIs. There was limited reporting of adverse effects, none of which could be meta-analysed. Where reported, they were limited to minor complaints, such as tiredness, nausea, headache and dry mouth (very low-certainty evidence). No adverse effects were reported for infants. Natural galactagogues Twenty-seven studies compared natural oral galactagogues (banana flower, fennel, fenugreek, ginger, ixbut, levant cotton, moringa, palm dates, pork knuckle, shatavari, silymarin, torbangun leaves or other natural mixtures) with placebo or no treatment. One study (Mother's Milk Tea) reported breastfeeding rates at six months with a concluding statement of "no significant difference" (no data and no measure of significance provided, 60 participants, very low-certainty evidence). Three studies (fennel, fenugreek, moringa, mixed botanical tea) reported infant weight but could not be meta-analysed due to substantial clinical and statistical heterogeneity (I² = 60%, 275 participants, very low-certainty evidence). Subgroup analysis shows we are very uncertain whether fennel or fenugreek improves infant weight, whereas moringa and mixed botanical tea may increase infant weight compared to placebo. Thirteen studies (Bu Xue Sheng Ru, Chanbao, Cui Ru, banana flower, fenugreek, ginger, moringa, fenugreek, ginger and turmeric mix, ixbut, mixed botanical tea, Sheng Ru He Ji, silymarin, Xian Tong Ru, palm dates; 962 participants) reported on milk volume, but meta-analysis was not possible due to substantial heterogeneity (I² = 99%). The subgroup analysis for each intervention suggested either benefit or little or no difference (very low-certainty evidence). There was limited reporting of adverse effects, none of which could be meta-analysed. Where reported, they were limited to minor complaints such as mothers with urine that smelled like maple syrup and urticaria in infants (very low-certainty evidence). Galactagogue versus galactagogue Eight studies (Chanbao; Bue Xue Sheng Ru, domperidone, moringa, fenugreek, palm dates, torbangun, moloco, Mu Er Wu You, Kun Yuan Tong Ru) compared one oral galactagogue with another. We were unable to perform meta-analysis because there was only one small study for each match-up, so we do not know if one galactagogue is better than another for any outcome.

AUTHORS' CONCLUSIONS

Due to extremely limited, very low certainty evidence, we do not know whether galactagogues have any effect on proportion of mothers who continued breastfeeding at 3, 4 and 6 months. There is low-certainty evidence that pharmacological galactagogues may increase milk volume. There is some evidence from subgroup analyses that natural galactagogues may benefit infant weight and milk volume in mothers with healthy, term infants, but due to substantial heterogeneity of the studies, imprecision of measurements and incomplete reporting, we are very uncertain about the magnitude of the effect. We are also uncertain if one galactagogue performs better than another. With limited data on adverse effects, we are uncertain if there are any concerning adverse effects with any particular galactagogue; those reported were minor complaints. High-quality RCTs on the efficacy and safety of galactagogues are urgently needed. A set of core outcomes to standardise infant weight and milk volume measurement is also needed, as well as a strong basis for the dose and dosage form used.

The prevalence, perceptions and behaviors associated with traditional/complementary medicine use by breastfeeding women living in Macau: a cross-sectional survey study

BACKGROUND

There is a long history of traditional/complementary medicine (T/CM) use by women during lactation. While it is important to evaluate such use within a scientific paradigm to ensure efficacy and safety, knowledge about the prevalence and characteristics of T/CM use during lactation is limited. This study aimed to generate preliminary data on the prevalence, perceptions and behaviors related to T/CM use by women living in Macau during lactation.

METHODS

Between April to June 2018, women aged 18 years or above who had breastfed within the previous 12 months were invited to complete a questionnaire which asked about their perceptions and behaviors related to the use of T/CM while breastfeeding. Chi-square analysis and logistic regressions were used to conduct data analysis.

RESULTS

A total of 500 women completed the survey with 62.6% (95% CI 58.37-66.83) reporting use of at least 1 T/CM while breastfeeding. Of these 48.9% (95% CI 44.67 to 53.13) believed T/CM were safe to take during lactation and 55.6% (95% CI 51.37 to 59.83) suggested there were inadequate resources to assist making an informed decision. Working status, monthly family income and the presence of a breastfeeding-related health problems were associated with T/CM use (all p < 0.05). The most commonly used T/CM were Tetrapanax papyriferus, lecithin, Vaccaria segetalis, docosahexaenoic acid and Trigonella foenum-graecum commonly referred to as Fenugreek. The most common reasons for using T/CM were "to unblock milk ducts", "to increase milk supply" and "to improve baby development". Women were recommended to use T/CM from multiple sources; 15.0% from health personnel (HP) only, 40.0% received recommendations from non-HP only; and 42.2% from both.

CONCLUSIONS

The use of T/CM by women during lactation is common in Macau. The current support and resources available to women during the breastfeeding period to make informed decisions about T/CM use is not standardized nor integrated. The gaps identified in this study provide an opportunity to develop resources and a more defined role for HPs to ensure the appropriate and safe use of T/CM in this population.

Integrating traditional Chinese medicines into professional community pharmacy practice in China - Key stakeholder perspectives

Introduction

In China, Traditional Chinese Medicine (TCM) is an integral part of the health system in parallel with Western medicine (WM). However, pharmacists’ duty of care at this interface has not been fully explored. This qualitative study aimed to explore key stakeholders’ perceptions about the challenges and enablers to pharmacists’ adopting a professional role in patient care associated with the concurrent use of herbal medicines (HMs).

Methods

Participants were recruited from the expert pool of the National Research Center for Licensed Pharmacist Development using purposive sampling and snowballing. Participants targeted included government, academics and practicing pharmacists. An interview guide was developed following a literature review and face-to-face, audiotaped interviews conducted with key stakeholders.

Results

Fourteen semi-structured interviews with both practicing pharmacists and key stakeholder representatives were conducted in China in 2017. Thematic analysis identified 6 main themes which focused on how TCM was integrated with WM in China. Participants agreed that pharmacists should at least assume a role in drug safety associated with concurrent use of TCM and WM. However, barriers were identified within the government, education, pharmacy, pharmacist and research sectors, indicating a lack of coordinated strategies to improve this area of healthcare. A lack of clarity in defining the pharmacists’ role in this area and a disconnect between current regulatory standards and education/training system were the prominent themes. Participants looked towards the government to facilitate actions in the development of policies that support pharmacy practice and practice guidelines, and the review of competency standards, and registration criteria as being the most important enablers.

Conclusion

Guiding principles that outline standards for pharmacy practice regarding HMs in an integrated healthcare system are considered a priority, requiring a joint effort from the government, professional organizations and universities.

Current Resources for Evidence-Based Practice, November 2019

A review of new resources to support the provision of evidence-based care for women and infants.
