Stop bleeding (zhi xue)

Herbs that stop abnormal bleeding, both externally and internally. This can include nosebleeds, coughing or vomiting blood, finding blood in the urine or the stool, or abnormal uterine bleeding. Some restrain the blood from leaking with their astringent properties, like bai ji (hyacinth orchid, Bletilla striata) and xian he cao (Agrimonia pilosa).

Others invigorate the blood to disperse stasis, like san qi (Sanchi ginseng, Panax notoginseng). Some cool the blood like da ji (Japanese thistle, Cirsium japonicum) and bai mao gen (Cogongrass rhizome, Imperata cylindrica).

Others warm the body like ai ye (Chinese mugwort, Artemisia argyi), which can dispel cold from the uterus that leads to abnormal bleeding.
