"There are two types of chamomile: German chamomile and Roman chamomile. This fact sheet focuses on German chamomile. Chamomile was described in ancient medical writings and was an important medicinal herb in ancient Egypt, Greece, and Rome. Today, chamomile is used as a dietary supplement for sleeplessness, anxiety, and gastrointestinal conditions such as upset stomach, gas, and diarrhea. It is also used topically for skin conditions and for mouth sores resulting from cancer treatment. The flowering tops of the chamomile plant are used to make teas, liquid extracts, capsules, or tablets. The herb can also be applied to the skin as a cream or an ointment, or used as a mouth rinse."
