ETHNOPHARMACOLOGICAL RELEVANCE: Ocotea guianensis Aubl. leaves, in Creole fey darjan ("silver leaves") are frequently cited by women in French Guiana for childbirth related practices. Although this use has been described in several ethnographic studies, the frequency of use of this plant has not been quantified yet. Moreover, beyond alarming anecdotes, the profile of users, the ways in which leaves are used during pregnancy, and its influence on childbirth and the immediate postpartum period remained to be determined. Our main objective was thus to estimate the frequency of O. guianensis use among women giving birth.
MATERIAL AND METHODS: A descriptive cross-sectional study was conducted in the maternity wards of Cayenne and Kourou in the immediate postpartum period. Data were collected from 332 women between March 21 and July 10, 2023. Women willing to participate were invited by multilingual health workers to answer a 10-min structured quantitative questionnaire. Qualitative individual interviews were also conducted with some caregivers and patients.
RESULTS: The frequency of use in the sample was 10 %. The leaves were generally used in the form of a sitz bath. Users were generally women born in French Guiana, with a relatively high level of education and social status. The study found no evidence of an increase in fetal distress or obstetrical complications in women who used O.guianensis compared with those who did not.
CONCLUSION: The study did not reveal any significant influence of O. guianensis use on pregnancy outcomes. Due to the small sample size of users and potential underreporting, this study may not have highlighted all user profiles in French Guiana. Even so, the study showed that the use of this herbal medicine concerned at least one in 10 women giving birth in Cayenne and Kourou, thus almost 484 deliveries per year. A complementary study conducted on a larger sample beyond maternity wards would refine usage frequency estimates and O. guianensis user profiles.
