2.8.1. Benefits of chamomile

Chamomile is used as a mild sedative and to aid digestion [32]. It has been used for the treatment of morning sickness [54]. German chamomile is the type used most often as a medicinal herb, extracts of which have been reported to increase the tone of uterus muscle [53]. Chamomile does not contain caffeine, which makes it safer for pregnant women, but there is some controversy over the safety of certain herbs not fully described by the Food and Drug Administration. There is insufficient information to say for sure whether chamomile can cause harm during pregnancy. As with many other herbs, the full effect of chamomile, especially in association with other medicines and herbs, has not been studied conclusively [55].
