Wood betony is a little known plant that is good for the urinary tract, gall bladder, and as a sedative for nervous conditions. In fact, at one time it had hundreds of uses as “cures” and was one of the most popular herbs around. It was a part of the official pharmacopeia-that list of medicinal herbs used by doctors, pharmacists and ordinary people to treat health problems. Knowledge of this plant is resurfacing and rightly so. You can buy wood betony products and you can grow the plants from seed (avaiable on-line). It is a short (12″) perennial hardy as far north as zone 4.
