Bái Zhú (白术) is the principal herb for strengthening the Spleen and drying dampness in Chinese medicine. The name means "white atractylodes" — 白 (Bái, white) distinguishes it from the related Cāng Zhú (苍术, Atractylodes lancea). The Spleen in TCM is responsible for transforming food and fluids into usable Qì and blood; when the Spleen is weak, dampness accumulates, digestion suffers, and fatigue sets in. Bái Zhú addresses this foundational dysfunction.

Botanical name: Atractylodes macrocephala Koidz. (Family: Asteraceae)

Part used: Rhizome

Nature: Warm

Flavor: Sweet, bitter

Meridians entered: Spleen, Stomach

Traditional Actions

Bái Zhú tonifies Spleen Qì, dries dampness, promotes urination, stabilizes the exterior to stop sweating, and calms the fetus during pregnancy. Its core function is strengthening the Spleen's capacity to transform and transport — the TCM equivalent of improving digestive efficiency and fluid metabolism.

The combination of tonifying and drying makes Bái Zhú uniquely suited for the common clinical scenario of Spleen Qì deficiency with dampness: fatigue, bloating, loose stools, poor appetite, and a heavy sensation in the limbs.

Relevance to Martial Arts

Strong digestion is the foundation of training capacity. In TCM, the Spleen and Stomach are the "acquired foundation" (后天之本) — the source of all postnatal Qì and blood. A practitioner with weak Spleen function cannot efficiently convert food into the energy and strength that training demands. Bái Zhú supports this fundamental process.

Cautions

Bái Zhú is contraindicated in conditions of Yīn deficiency with heat and extreme thirst. Its drying nature can aggravate fluid-deficient conditions. This article describes traditional uses and does not constitute medical advice.
