Largehead Atractylodes Rhizome / Bai Zhu

【Benefits】

In traditional Chinese medicine, Atractylodes macrocephala (Bai Zhu) is renowned for its effects of invigorating spleen qi, drying dampness and promoting diuresis, arresting sweating, and preventing miscarriage. It effectively alleviates symptoms like poor appetite, loose stools due to spleen deficiency, edema caused by dampness retention, spontaneous sweating from qi deficiency, and threatened miscarriage due to spleen-kidney weakness. From a modern research perspective, it contains bioactive components such as Atractylodes polysaccharides, volatile oils (e.g., atractylon), and flavonoids, which have immunomodulatory, antioxidant, and digestive function-regulating effects, helping to enhance the body's resistance and improve gastrointestinal motility.

【Properties and Tastes】

Tastes sweet, bitter; warm in nature; enters the Spleen and Stomach meridians

【Medicinal Components & Effects】

Atractylodes macrocephala is rich in active components. Atractylodes polysaccharides are the key, exerting immunomodulatory, anti-fatigue, and antioxidant effects. Volatile oils (main component: atractylon) can dry dampness, invigorate spleen qi, and regulate gastrointestinal peristalsis, relieving abdominal distension and loose stools. Flavonoids contribute to its anti-inflammatory and free-radical scavenging abilities. These components work together to strengthen the spleen, eliminate dampness, and maintain the body's digestive and metabolic balance.

【Storage Methods】

• Store in a cool, dry, and well-ventilated place, away from direct sunlight and high humidity to prevent mold, insect infestation, or loss of potency. Its volatile oils are prone to volatilization, so sealed storage is crucial.
• Use airtight containers like glass jars or vacuum-sealed bags. Ensure the container is sealed tightly after each use to avoid moisture absorption and volatilization of active components.
• Regularly check for signs of spoilage, such as mold, softening, or unusual odor (e.g., sourness). Discard any spoiled Atractylodes macrocephala immediately.
