Calcined Gypsum Classic Formulas — Natural Herb Library

Primary Actions

Generates flesh and heals sores - the processed form is classically dusted on ulcers, difficult wounds, and erosive lesions that need drying plus tissue regeneration.
Dries Dampness and closes weeping skin lesions - used externally for eczema, damp erosions, and moist lesions where raw Shi Gao would be the wrong preparation.
Relieves pain and protects damaged tissue in burns and scalds - applied as an external powder when heat injury has damaged the skin surface and a cooling-drying protective mineral is needed.

Duan Shi Gao with Qing Dai and Huang Bai - external powder style for damp-hot eczema and weeping lesions.
Duan Shi Gao with Bing Pian or sesame oil - topical burn and scald applications aimed at pain relief and surface protection.
Duan Shi Gao with Er Cha and related astringent wound powders - used when chronic ulcer beds need both drying and flesh-generation support.

Me & Qi explicitly states that the 'generates flesh and heals sores' action belongs only to the calcined form, Duan Shi Gao, which is applied externally to wounds, burns, eczema, and chronic ulcers.
The same Me & Qi monograph strongly warns that calcined Shi Gao must not be used internally because it no longer behaves like the raw heat-clearing mineral.
PREPARATION NOTE: this file is intentionally separate from raw Shi Gao because calcination changes both the therapeutic target and the safety profile.
