- Betony has been regarded as a cure-all by many societies including Greece, Italy, Spain, and Britain, as far back as 2,000 years ago. Its constituents include tannins, alkaloids and glycosides, which are typically the active ingredients in herbal remedies.
- Its most commonly reported use is as a nervine (sedative or relaxing agent); the validity of this application has not been confirmed with clinical research.
