Botanical Description
Hong Fen, also called Hong Sheng Dan, is a refined mineral substance composed primarily of mercurous chloride (Hg2Cl2, calomel) and mercuric oxide (HgO), produced historically by sublimation from mercury, alum, and nitre. The product appears as bright red to orange crystalline scales or powder. In classical TCM it was used externally only, applied to chronic ulcers, abscesses, syphilitic chancres, and non-healing sores to remove necrotic tissue and promote granulation. Owing to its severe mercury toxicity and risk of systemic poisoning through skin and mucosal absorption, modern clinical practice strictly discourages internal use and limits external application to very small quantities in carefully formulated topical preparations. It is regulated as a toxic substance in the Chinese Pharmacopoeia.
