“…There are some herbal medicines which can be used safely during pregnancy, for example, air plant (Bryophyllum pinnatum) for sleep quality, German chamomile (Matricaria recutita L.) as an antiinflammatory and uterine tonic but also for anxiety, nausea, and vomiting, peppermint (Mentha × piperita L.) is the most commonly used for indigestion/heartburn and nausea/morning sickness, whereas echinacea (Echinacea sp. L.) is used to prevent or treat cold or the flu and in general boost the immune system; and ginger (Zingiber officinale Roscoe) is a common herb for nausea and vomiting with potential mild adverse effects such as drowsiness and heartburn (Araújo, Santiago, Peixoto, de Oliveira, & de Sousa Coutinho, 2016;Bishop, Northstone, Green, & Thompson, 2011;Broussard, Louik, Honein, & Mitchell, 2010;Dennehy, 2011;Holst, Wright, Haavik, & Nordeng, 2011;Kolding, Pedersen, Henriksen, Olsen, & Grzeskowiak, 2015;Moretti, Maxson, Hanna, & Koren, 2009;Petersen, McCrea, Lupattelli, Nordeng, 2015;Orief et al, 2014;Viljoen, Visser, Koen, & Musekiwa, 2014;Wang, Li, San Lau, Leung, & Fung, 2013). However, clinical data concerning safety of maternal exposure to herbal medicines during pregnancy are often inconclusive due to small sample sizes, ethical reservations, and incomplete study designs.…”
