Raw Gypsum (Shi Gao) — Dried Mineral Herb Pieces for TCM Decoction & Food Use

Raw Gypsum (Gypsum fibrosum) is the naturally mined mineral long revered in Traditional Chinese Medicine (TCM) as Shēng Gāo (生石膏). For centuries, Sheng Gao has been prized as a heat-clearing, fire-purging mineral herb, traditionally used to cool the Stomach, quench thirst, and calm restlessness associated with excess internal heat. Its nature is sweet, pungent, and markedly cold, making it a powerful yet focused mineral for clearing heat while preserving fluids. This food-herb (药食同源) grade material is sourced from mainland China and offered as dried block, granule, and powder forms.

Quality & Sensory

Each batch is sun-dried to preserve its characteristic pale white to slightly greyish color, dense fibrous texture, and cool, mineral feel. In block form it is firm and layered; as granules it is coarse and free-flowing; milled powder is fine and chalky. It carries little to no aroma. When decocted, it releases a neutral, faintly mineral taste that does not overpower companion herbs, and the decoction is typically taken warm.

Traditional Uses

In folk herbal practice, Sheng Gao is decocted into cooling soups and heat-clearing formulas, often paired with herbs such as Zhi Mu, Gan Cao, or Mai Dong to support fluid balance during hot seasons. It is a classic ingredient in traditional summer decoctions and is sometimes added to medicinal food soups where a cooling, mineral quality is desired. As a daily preparation, it is brewed in combination with other gentle herbs rather than used alone.
