Chamomile
Chamomile has been used as a traditional medicine for thousands of years to calm anxiety and settle stomachs. In the U.S., chamomile is best known as an ingredient in herbal tea. Chamomile is considered a safe plant and has been used in many cultures for stomach ailments and as a mild sedative. Some studies, primarily using combinations of chamomile with other plants, show it may have health benefits. However, as with any combination product, it is hard to say that a benefit comes from any one plant.
