The root of rhatany comes to market in cylindrical pieces of various lengths, and in diameters from an eighth of an inch to two inches. The bark is reddish-brown, brittle, and easily separable from the yellowish-red center. The chief medicinal strength lies in the bark, which contains about forty percent of tannic acid.

Rhatany is a powerful astringent that was retained in the official pharmacopea until recently.  It may be used wherever an astringent is indicated, that is, in diarrhea, hemorrhoids, hemorrhages or as a styptic.  Rhatany is often found in herbal toothpastes and powders as it is especially good for bleeding gums. It can be used as a snuff with bloodroot to treat nasal polyps.  The plant’s astringency makes it effective when used in the form of an ointment, suppository, or wash for treating hemorrhoids.  Rhatany may also be applied to wounds to help staunch blood flow, to varicose veins, and over areas of capillary fragility that may be prone to easy bruising.   Gargle the tea or diluted tincture for acute or lingering sore throat.  It can be combined for this purpose with Yerba Mansa or Echinacea.  For diarrhea, combine with Silk Tassel (for cramps) and Echinacea (immunostimulant), and with either Trumpet Creeper, Desert Willow or Tonadora (for Candida) and Chaparro Amargosa (Protozoas).  For a hemorrhoidal salve and rectal fissure ointment, use either alone or with Echinacea flowers as a salve.
