Herbal medicine use by pregnant women in Bangladesh: a cross-sectional study

BACKGROUND: Herbal medicines in pregnancy are increasingly used worldwide with prevalence of up to 67%. Although this popularity is mainly because of the common belief that these medicines are safe, recent reports suggest that several herbal medicines are potentially harmful to mother and fetus if used in pregnancy. METHODS: This cross-sectional study was conducted in July and August of year 2017, at maternity wards of two public hospitals in Dhaka, Bangladesh. Postpartum women were interviewed via the structured questionnaire to collect information regarding socio-demographic and health characteristics, patterns of herbal medicines used in the previous pregnancy, and outcome of pregnancy. RESULTS: Two hundred forty-three postpartum women participated in the study, with 70% of them using at least one modality of herbal medicines in previous pregnancy. Ginger, black seed, lemon tea, prune, and mustard oil were most commonly used herbal medicines. Herbal medicines were mostly used for pregnancy-related symptoms such as nausea, vomiting, and cold. Fifteen (8.8%) herbal medicine users reported side effects. CONCLUSIONS: This study highlights popularity of herbal medicines during pregnancy in Bangladesh. Previous herbal medicine users and unemployed women turned significantly more to herbal medicines during pregnancy. Reports of side effects and use of some potentially harmful modalities warrant awareness regarding proper use of herbal medicines in pregnancy and its pharmacovigilance.
