Botanical Description

Yu Liang Shi (็ฆน้ค˜็ณง) is the Chinese materia medica name for limonite, a yellow-brown to dark brown mineral consisting principally of hydrated iron oxides (chiefly goethite, FeO(OH), with admixed clay and other earthy components). The medicinal-grade material is gathered as concretionary or earthy lumps, often hollow or kidney-shaped, traditionally said to occur near the legendary tomb of Yu the Great. Pieces are calcined and quenched in vinegar, then powdered for use. In TCM, Yu Liang Shi is classified as sweet, astringent, and neutral, entering the Stomach and Large Intestine channels, and is used to bind the intestines and stop diarrhea, stop uterine bleeding, and arrest leukorrhea. Classical indications include chronic diarrhea, dysentery, prolonged uterine bleeding, and abnormal vaginal discharge.
