After harvesting, it is cleaned, dried, and often sliced for herbal use. Good-quality material is dense, dry, low in fibrous tissue, and free from mold.

Scientific name: Atractylodes macrocephala

The name Bạch truật distinguishes this herb from Cang Zhu. Although related, they are not interchangeable. Bai Zhu mainly tonifies the Spleen, while Cang Zhu has a stronger Dampness-drying action.

3. Flavors, Nature – Meridian

According to TCM theory, Bai Zhu has Sweet and Bitter flavors and a Warm nature. The Sweet flavor is associated with nourishment and tonification. The Bitter flavor helps dry Dampness, while the Warm nature supports Spleen Yang and the movement of fluids.

It mainly enters two Meridians:

• Spleen Meridian: Traditionally used to strengthen digestion, support the production of Qi and Blood, reduce loose stools, and improve energy when Spleen Qi is weak.
• Stomach Meridian: Traditionally used to support appetite, relieve abdominal fullness, and improve the processing of food and fluids.

Because it is warming and drying, it may not suit people with Yin deficiency, internal Heat, severe dryness, or constipation.

4. Benefits of White Atractylodes in TCM

White atractylodes is commonly used in TCM formulas for digestive weakness and fatigue. Its main traditional benefits include:

• Strengthening the Spleen: May be considered when poor appetite, abdominal heaviness, or low energy is linked to Spleen Qi deficiency.
• Supporting digestion: Traditionally used for slow digestion, abdominal fullness, mild nausea, or discomfort after eating.
• Reducing loose stools: Frequently included in formulas for recurrent or chronic loose stools associated with digestive weakness.
• Supporting fluid metabolism: Traditionally used to help the body manage excess Dampness and mild swelling associated with weak Spleen function.
• Improving physical strength: Often combined with other Qi-tonifying herbs for older adults, people recovering from illness, or those experiencing persistent tiredness.
• Supporting selected pregnancy formulas: Classical TCM may include Bai Zhu when Spleen Qi deficiency is present, but only under qualified supervision.

These traditional uses do not replace medical care. Persistent diarrhea, weight loss, severe abdominal pain, vomiting, swelling, or prolonged fatigue requires professional assessment.

5. How to use and dosage

The usual reference dosage is 6–12 g per day in a decoction. The amount depends on constitution, symptoms, preparation, and accompanying herbs.
