Xue Yu Tan血余炭
Crinis carbonisatus · Carbonized Hair · Charred Human Hair
Overview
Human hair, cleaned and carbonized until it crumbles — a preparation the materia medica has carried since antiquity. Bitter and neutral, it restrains bleeding without holding stasis in place, which is what makes it usable for nosebleed, coughed or vomited blood, blood in the stool or urine and uterine bleeding; it also promotes urination in painful, bloody dribbling urination. It is given in decoction and, more often, ground and swallowed as a powder.

Cautions
Only properly carbonized, pharmacy-grade material is used — hair that has not been prepared correctly is not medicine, and this is not something to make at home. Its rich, greasy quality can unsettle a weak stomach, so use it cautiously with poor appetite and loose stool. Any unexplained or heavy bleeding needs a medical diagnosis first.
