Processing (simplified Chinese: 炮制; traditional Chinese: 炮製; pinyin: páozhì, or Chinese: 炮炙; pinyin: páozhì) in Chinese materia medica (Chinese herbology) is the technique of altering the properties of crude medicines by processing using heat and combination with various materials in a kind of alchemical approach to preparation.

Methods[edit]

Pao Zhi processing may involve such means as roasting, honey frying, wine frying, earth frying, vinegar frying, calcining, or other means. This is a kind of alchemical processing used in everyday preparation of herbal, mineral and animal medicinals.

There are also more esoteric traditions of processing, including those involving mercury, but the term is used to refer to the more common preparations. For instance, frying with wine is believed to enhance the circulatory properties of herbs. Frying with salt is believed to draw the herbal actions to the kidneys. Otherwise cooling herbs may be warmed up by heated techniques.[1][2][3] These techniques have been applied to Western herbal medicine in the David Winston Center for Herbal Studies for the last 20 years.[4]
