Harvesting and processing

Harvest
Autumn (October-November), 2-3 year old plants

Rhizomes harvested when the aerial parts turn yellow. The soil is cleaned, secondary roots are removed and dried. The larger rhizomes are called 大白术 (dà bái zhú) and are of better quality.

Raw (生白术 Shēng Bái Zhú)

Rhizome cleaned, boiled briefly to facilitate cutting, cut into 3-5 mm slices and dried in the sun or with gentle heat. Brief boiling inactivates enzymes but preserves polysaccharides.

Fried with bran (麸炒白术 Fū Chǎo Bái Zhú)

Slices mixed with hot wheat bran (10 g bran per 100 g of grass) in a pan, fried, stirring until the bran is smoking and the slices are golden brown. The bran is removed with a sieve.

Fried with earth (土炒白术 Tǔ Chǎo Bái Zhú)

Fried slices with heated oven soil (灶心土 Zào Xīn Tǔ). The earth acts as a heat intermediary and adds astringent properties that strengthen the Spleen.
