Survey of Raspberry Leaf Tea in pregnancy

Abstract

Background Raspberry leaf tea (RLT) is a traditional herb purported to help with many pregnancy-related outcomes including reducing the duration of labour. No experimental data exist to support these claims. Aims This study aims to determine how common use and knowledge of RLT are during pregnancy. It also aims to explore whether it would be possible to recruit women for a trial of raspberry leaf in the future. Materials and methods Postnatal women were asked to fill in a survey about their use of RLT during pregnancy, and their knowledge of its purported benefits. They were asked whether they would consider being part of a randomised controlled trial of raspberry leaf in the future. Results One hundred and twenty-one women completed the survey. Of these, 88 (73%) were aware of herbal tea use in pregnancy and 46 (38%) reported using raspberry leaf during pregnancy. Of all women surveyed, 79% indicated they would be happy to participate in a trial of RLT in pregnancy if they were asked. Conclusions Despite no scientific evidence of the efficacy of RLT in pregnancy, 38% of women surveyed used it during pregnancy. Further studies are required to determine whether the claims made about RLT are correct. Clinicians should base their advice on available evidence.
