# Atractylodes (Atractylodes macrocephala) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/atractylodes **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-20 **Evidence Score:** 2 / 10 **Category:** Traditional Chinese Medicine **Also Known As:** Atractylodes macrocephala, Baizhu, Bai Zhu, White Atractylodes, Large-headed Atractylodes, Chinese Atractylodes, Cang Zhu ## Overview Atractylodes macrocephala is a traditional Chinese medicine herb containing bioactive compounds like atractylon and atractylenolides that modulate immune function and provide [hepatoprotective](/ingredients/condition/detox) effects. The herb demonstrates [antioxidant](/ingredients/condition/antioxidant), antitumor, and [immunomodulatory](/ingredients/condition/immune-support) properties through multiple cellular pathways. ## Health Benefits • [Immunomodulat](/ingredients/condition/immune-support)ion: Exhibits immune-boosting properties in preclinical studies. • Antitumor Effects: Demonstrated antitumor activities in animal and in vitro studies. • [Antioxidant Activity](/ingredients/condition/antioxidant): Acts as an antioxidant according to preclinical research. • [Hepatoprotect](/ingredients/condition/detox)ion: Offers liver protection in animal models. • Gastrointestinal Protection: Supports gastrointestinal health, evidenced by preclinical data. ## Mechanism of Action Atractylodes macrocephala's bioactive compounds, particularly atractylenolides I-III and atractylon, modulate [immune function](/ingredients/condition/immune-support) by enhancing macrophage activity and cytokine production. The herb's [hepatoprotective](/ingredients/condition/detox) effects involve activation of [antioxidant](/ingredients/condition/antioxidant) enzymes like superoxide dismutase and glutathione peroxidase while inhibiting [inflammatory pathway](/ingredients/condition/inflammation)s including NF-κB signaling. ## Clinical Summary Current research on Atractylodes macrocephala consists primarily of preclinical studies using animal models and in vitro cell cultures. Animal studies have shown immune enhancement effects at doses of 200-400mg/kg body weight, with significant increases in [white blood cell](/ingredients/condition/immune-support) counts and antibody production. [Hepatoprotective](/ingredients/condition/detox) studies in rats demonstrated 40-60% reduction in liver enzyme markers when administered alongside hepatotoxic agents. However, human clinical trials are limited and more research is needed to establish therapeutic efficacy in humans. ## Nutritional Profile Atractylodes macrocephala (Bai Zhu) rhizome is primarily valued for its bioactive compounds rather than conventional macronutrients. Key constituents include: Polysaccharides (AMPs: Atractylodes macrocephala polysaccharides) at approximately 15–45% dry weight, representing the primary [immunomodulatory](/ingredients/condition/immune-support) fraction. Volatile oils comprise 1.0–1.5% of the dried rhizome, dominated by atractylone (a sesquiterpene ketone, ~20–30% of volatile fraction), β-eudesmol (~15–20%), and atractylenolides I, II, and III (lactone compounds, collectively ~0.1–0.5% dry weight) — these are the principal antitumor and [anti-inflammatory](/ingredients/condition/inflammation) bioactives. Inulin-type fructooligosaccharides are present at roughly 10–20% dry weight, contributing [prebiotic](/ingredients/condition/gut-health) and gastrointestinal-supportive effects. Crude fiber content is approximately 10–15% dry weight. Protein content is low at ~5–8% dry weight, with limited bioavailability after typical preparation. Fat content is minimal at ~2–3% dry weight. Micronutrients include modest levels of potassium (~300–400 mg/100g dried), calcium (~100–150 mg/100g), magnesium (~50–80 mg/100g), and trace iron (~5–10 mg/100g). Vitamin content is negligible after drying and decoction processing. Bioavailability note: Atractylolides and polysaccharides show enhanced extraction in hot-water decoction (traditional preparation); lipophilic atractylone is better extracted in ethanolic preparations. Oral bioavailability of atractylenolide I is estimated at 20–40% based on rodent pharmacokinetic studies, with significant first-pass hepatic [metabolism](/ingredients/condition/weight-management). ## Dosage & Preparation No clinically studied dosage ranges for extracts, powders, or standardized forms are specified due to the absence of human trials. Traditional TCM use employs decoctions without quantified standardization. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Atractylodes macrocephala is generally considered safe when used appropriately, though mild gastrointestinal upset may occur in some individuals. The herb may interact with immunosuppressive medications due to its immune-stimulating properties, potentially reducing their effectiveness. Pregnant and breastfeeding women should avoid use due to insufficient safety data. Individuals with autoimmune conditions should consult healthcare providers before use as the herb's [immunomodulatory](/ingredients/condition/immune-support) effects could potentially exacerbate these conditions. ## Scientific Research No specific human clinical trials, RCTs, or meta-analyses with PubMed PMIDs are available for Atractylodes macrocephala. Current evidence is based on preclinical studies primarily involving animal and in vitro models. ## Historical & Cultural Context In traditional Chinese medicine, Atractylodes macrocephala has been used for centuries to strengthen the spleen, benefit qi, dry dampness, and prevent miscarriage. Its applications are deeply rooted in ancient Chinese herbal practices. ## Synergistic Combinations Reishi, Ginseng, Licorice, Astragalus, Ginger ## Frequently Asked Questions ### What is the recommended dosage of Atractylodes macrocephala? Traditional Chinese medicine typically uses 6-12 grams of dried Atractylodes macrocephala root daily, often prepared as a decoction. Standardized extracts are commonly dosed at 200-400mg daily, though optimal human dosing requires more clinical research. ### How long does it take for Atractylodes macrocephala to show effects? Based on animal studies, immune-modulating effects may begin within 1-2 weeks of consistent use. However, traditional Chinese medicine practices suggest 4-8 weeks of regular use for optimal benefits, though human timeframes are not well-established. ### Can Atractylodes macrocephala be taken with other supplements? Atractylodes macrocephala is commonly combined with other TCM herbs like ginseng and licorice root in traditional formulas. However, it should be used cautiously with immune-suppressing medications or other immune-stimulating supplements to avoid interactions. ### What are the active compounds in Atractylodes macrocephala? The primary bioactive compounds include atractylenolides I, II, and III, along with atractylon and various polysaccharides. These sesquiterpene lactones and volatile oils are responsible for the herb's immunomodulatory and hepatoprotective properties. ### Is Atractylodes macrocephala the same as white atractylodes? Yes, Atractylodes macrocephala is commonly known as white atractylodes or bai zhu in traditional Chinese medicine. This distinguishes it from Atractylodes lancea (cang zhu), which has different therapeutic properties and applications. ### Is Atractylodes macrocephala safe during pregnancy and breastfeeding? Limited safety data exists for Atractylodes macrocephala use during pregnancy and breastfeeding, so it is generally recommended to avoid supplementation during these periods unless under professional guidance. Traditional use suggests it was employed to support digestive health, but pregnant and nursing individuals should consult a healthcare provider before use to ensure safety for both mother and child. ### Does Atractylodes macrocephala interact with common medications? While Atractylodes macrocephala has not been extensively studied for drug interactions, its immunomodulatory properties suggest potential interactions with immunosuppressant medications used in transplant or autoimmune conditions.
