What is the purpose and significance of Rhizoma Atractylodis processing?

Prepare herbs by frying.

1. Brand system

Take bran, sprinkle it in a hot pot, heat it until it smokes, add Atractylodes lancea, turn it quickly, fry it until the surface is dark yellow, take it out, sieve off the bran and let it cool. Atractylodes rhizome 100kg, bran 10kg (Pharmacopoeia 85).

fried dishes

(1) fry yellow

Slice Rhizoma Atractylodis, put it in a pot, fry it with slow fire until it is slightly yellow, take it out and let it cool (Pharmacopoeia).

(2) frying

Slice Rhizoma Atractylodis, put it in a pot, bake it with strong fire sand, take it out, and sift out the dust (Hubei). Build a system

Slice Rhizoma Atractylodis, spray it with rice swill, put it in a pot and fry it with slow fire until it is slightly yellow; Or wash Rhizoma Atractylodis, soak it in rice swill, take it out, put it in a steamer, steam it thoroughly, take it out and dry it (Pharmacopoeia 63).

4. homemade

Stir-fry the center of the stove in a hot pot, pour in Rhizoma Atractylodis slices, stir-fry over medium heat until you smell the inherent fragrance of Rhizoma Atractylodis, take it out, remove the soil and let it cool. Rhizoma Atractylodis slices each 500g, boiled soil 150g (Henan).

Make with salt

Stir-fry Rhizoma Atractylodis with strong fire until the epidermis is brown, add salt water, stir-fry and take out. Atractylodes rhizome 1kg, salt 0.05kg, and appropriate amount of water (integrated).

Make charcoal

Wash Rhizoma Atractylodis, heat it in a pot, stir-fry it evenly with an iron rake until it is dark brown, spray clean water in time, take it out, put it in a container, stir to dissipate heat, and let it cool after the smoke is exhausted.

Modern research

1. The volatile oil content of Rhizoma Atractylodis soaked in rice bran is indeed lower than the original medicinal material, which proves that Li Shizhen's statement of "controlling its dryness" is correct to remove its oil.

2. The effects of different processing methods on the volatile oil content of Atractylodes lancea were compared and studied. The results showed that the content of volatile oil in Rhizoma Atractylodis decreased after frying, bran frying and rice washing, among which bran frying and rice washing had the best degreasing effect, with degreasing rates of 39% and 47% respectively. The decoction pieces have good appearance quality and simple operation. It is suggested that these two methods be used in the processing of Atractylodes lancea in the future.
