Gypsum fibrosum (Shi Gao), a Traditional Chinese Medicine, is a kind of mineral substance containing calcium sulphate. Unprocessed Shi Gao can strongly clear excessive heat in the lung, while processed Shi Gao can be applied topically to moisturise the skin and also to treat skin diseases or wounds. It is clearly seen that gypsum has a slew of benefits to skin.
It is good at maintaining cutaneous water content, which means it deeply moisturises your skin and more importantly, reduces the chance of any skin problems such as acne and wrinkles. Besides, it is also effective in repairing and restoring the damaged tissue, thereby creating a smoother skin.
Lastly, to make it clear, gypsum used in TCM is totally different from the industrial gypsum which is used in treatment of bone fractures.
