@petertheo I copied this from a post about it, Known by many other names (yellow pucoon, golden root…) goldenseal root has long been a favored medicine of North America. It has been used for countless generations by many indigenous people for a wide variety of conditions. Goldenseal has been primarily known for its antibiotic, antifungal, anti-inflammatory and anti cancer activities. Scientific studies have linked these effects to the presence of berberine and hyrdrastine.
Goldenseal has been used externally as an antiseptic wound cleaner, mouthwash, eyewash and to treat a variety of skin ailments including eczema and poison ivy. Internally, it has been used primarily to treat infections of mucus membranes; sinuses, respiratory tract, throat, mouth and urinary tract. Goldenseal is considered a bitter tonic, and therefore stimulates the flow of bile and has been used for digestive upsets, ulcers, diarrhea, and colitis.
