Growing and Saving the Seed Of Betony

Latin name Stachys officinalis is a perennial member of the mint family. Its astringency and mild bitterness have made it a valued wound and digestive remedy, but its most popular modern use is in treating tension and pain-inducing migraines. Perennial in USDA zones 5-10.



This perennial herb was highly prized in the Middle Ages for its medicinal properties, and even an old Italian proverb says “sell your coat and buy Betony.” It is still found growing around ancient physic gardens and monasteries, where it was traditionally used to treat arthritis and gout.
