How it works
Bitter tradition: Goldenseal has traditionally been used in measured digestive preparations. Herbal meaning: Herbalists associate it with the mucous membranes—the moist linings of areas such as the mouth and digestive tract. Its concentrated bitter character makes it a specialist ingredient within that tradition.
In the tradition
Associated with North American herbal practice.
