NOTE:
1. Two separate medicines come under the heading of Atractylodes: White (Bai Zhu) and Dark (Cang Zhu). The White is stronger to increase Qi and tonify the Spleen, for weakness and fatigue. The Red is stronger to alleviate Damp and also promotes sweat due to its warm and aromatic nature. They are combined for cases with both marked deficiency and damp. In cases where Bai Zhu is required but the person has significant Damp but less debility, Cang Zhu may replace Bai Zhu. In formulas requesting Cang Zhu, Bai Zhu may be used if there is marked debility.
2. The two Atractylodes are similar to the Inula (Elecampane) and Costus combination often used in Tibet and India. Inula is stronger to tonfy the Qi, Costus is stronger to move Qi and is more drying and aromatic. The two together more strongly strengthen the Spleen, tonfy Qi and clear Damp and Stagnation. The same can be said of the combination of White and Dark Atractylodes.

PREPARATION:
Bai Zhu:
1. Washed White Atractylodes (Piao Bai Zhu):
  The root or sliced root is soaked in Rice-rinse water, steamed until black, then sun-dried. This lessens its drying effect. It is better for Spleen weakness with Diarrhea.
2. Dry-fried White Atractylodes (Chao Bai Zhu):
  The root is dry-fried with Bran to enhance its Spleen tonifying effect. It may also be stir-fried with earth to enhance its effect against Diarrhea associated with Spleen weakness.
3, Scorched White Atractylodes (Jiao Bai Zhu):
  The sliced root is dry-fried until scorched, then sprayed with water and dried in the sun. This lessens its drying effect, but is better to strengthen the Spleen and Stomach and improve appetite and digestion.

Cang Zhu:
1. Prepared Dark Atractylodes (Zhi Cang Zhu):
  The root is soaked in Rice-rinse water, steamed until black, then sun-dried. This lessens its drying and dispersing effect and stops its diaphoretic effect. It is better for weak patients with excess Damp.
2. Dry-fried Dark Atractylodes (Chao Cang Zhu):
  The herb is either dry fried alone until darkened, or else dry-fried with bran or earth until yellowish-brown. This makes it more drying while reducing its drying and dispersing nature. That fried alone is better for Diarrhea; that fried with Bran is better to harmonise the Stomach; dry-frying with earth enhances the Spleen-tonifying effect.

DOSE:
The prepared types are used in the same doses as the unprepared root.
Bai Zhu (White Atractylodes): 6–15 grams in Decoction; 1.5–4 grams in powder
Cang Zhu (Dark Atractylodes): 3–9 grams; 1–3 grams in Powder
