What is it used for?
Few plants have as widespread a history as betony. Its use has been known since the Roman Empire, when it was considered a remedy for a wide variety of diseases. During the Middle Ages, the plant was ascribed magical powers. Today the plant continues to be used in traditional medicine. A weak infusion sometimes is taken as a tea. It is used as an astringent to treat diarrhea and as a gargle or tea for irritations of the mouth and throat. It has been used to treat anxiety and has been given as a tincture or smoked for the treatment of headache. The name "betony" may derive from the Celtic form of bew (a head) and ton (good).
Experimental or clinical studies to support the many traditional uses of betony are limited. Antioxidant, antimicrobial, and anti-inflammatory effects have been demonstrated in animal or in vitro studies only.
