Ku Fan (Calcined Alum) — Dried Mineral Herb for External & Traditional Use, 500g

Ku Fan (煅白矾), also known as Calcined Alum or Bái Fán (白矾), is the dried mineral product obtained by calcining alum, a substance long recorded in Traditional Chinese Medicine (TCM) materia medica. In TCM it is classified as a mineral herb with a sour, astringent, and cold nature, traditionally associated with the Lung, Liver, and Spleen channels. It has been prized for centuries as an astringent, drying, and phlegm-transforming agent used in external washes, topical preparations, and traditional formulas.

Quality & Sensory

Each batch of Ku Fan is calcined to produce a light, porous, white to off-white mass with a chalky, brittle texture that crumbles easily. It has a faint mineral aroma and a mild astringent taste. When dissolved or decocted, it yields a clear, slightly mineral-tasting liquid, and when ground, it becomes a fine, smooth powder suitable for blending into external preparations.
