Astringents are substances that have a constricting or binding effect. They are commonly used to check hemorrhages and secretions, and to treat swollen tonsils and hemorrhoids. The main herbal astringents contain tannins, which are found most plants, especially in tree barks.
Important astringents include: bayberry bark, white oak bark, yellow dock, uva ursi, calendula, myrrh, horsetail, juniper berries, prince's pine, stoneroot, squawvine, and witch hazel.
