Dried alum is called calcined alum (Kufan). Licorice root (Gancao) serves as a guiding herb; it is incompatible with oyster shell (Muli) and fears Ephedra (Mahuang) and other substances.
It tastes sour, is cold in nature, and is non-toxic. It dries dampness, directs rebellious phlegm downward, detoxifies, generates fluids, removes lice, kills parasites, stops bleeding, and alleviates pain. It promotes the unblocking of both bowel and bladder movements, cauterizes foul flesh, treats various sores, and stops white dysentery. It clears deep-seated heat from the bones, flattens nasal polyps, stops bleeding from the gum spaces, and treats aphonia caused by wind-stroke. It treats all kinds of carbuncles, furuncles, malignant sores, scrofula, tinea, rat sores, throat obstruction, epistaxis, epilepsy, and injuries from toxic substances.
Alum stone initially forms as rock; after being crushed, roasted, and refined, it becomes alum. There are five colors: white, yellow, green, black, and crimson. Currently, white alum is produced in Cizhou and Jinzhou; it is widely used by dyers but rarely used in medical prescriptions.
