The Short Answer
He Shou Wu (Polygonum multiflorum) contains stilbene glycosides that enhance blood circulation and liver antioxidant activity. The compound 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside (TSG) primarily drives its hair growth and hepatoprotective effects.

Health Benefits
Supports hair health by promoting hair follicle growth, potentially reducing hair loss. This is due to its ability to enhance blood circulation in the scalp. - Boosts liver function by increasing antioxidant levels, which help detoxify the liver. This is essential for maintaining overall metabolic health. - Enhances kidney health by reducing oxidative stress, which can improve renal function. This is crucial for filtering waste from the body effectively. - Improves cardiovascular health by lowering cholesterol levels, reducing the risk of heart disease. Studies show a 15% decrease in LDL cholesterol. - Increases energy levels by improving mitochondrial function, which enhances cellular energy production. This is beneficial for combating fatigue. - Supports cognitive function by preventing neurodegeneration, which can enhance memory and learning. This is vital for maintaining mental acuity. - Boosts immune response by modulating cytokine production, which helps the body fight infections more effectively.
Origin & History
Natural habitat
He Shou Wu is a root of the Polygonum multiflorum plant, native to China. It is traditionally prepared by steaming with black beans to reduce toxicity.
“Traditionally used in Chinese medicine, He Shou Wu is famed for its ability to restore hair color and promote longevity. It is named after a legendary figure who supposedly regained his youthfulness and vitality by using it.”Traditional Medicine
Scientific Research
Some studies suggest He Shou Wu may have antioxidant and anti-aging properties, but more research, including clinical trials, is needed to confirm its efficacy.
Preparation & Dosage
Traditional preparation
Dosage ranges from 3-12 grams per day. Consult a healthcare provider before use.
Nutritional Profile
He Shou Wu (Polygonum multiflorum) root is not a significant source of macronutrients in typical supplemental doses (3–9g dried root/day), but contains notable bioactive compounds. Stilbenes: trans-resveratrol (~0.02–0.1mg/g dried root) and its glycoside polydatin (~1–5mg/g). Anthraquinones: emodin (~0.5–2mg/g) and physcion (~0.3–1.5mg/g), with emodin being hepatotoxically relevant at high doses; processing (Zhi He Shou Wu, prepared with black bean soup) significantly reduces free anthraquinone content by ~50–70% compared to raw root. Stilbene glycosides: 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside (THSG, the primary bioactive marker compound) at approximately 1.0–2.5mg/g in raw root, often standardized to ≥1.0% in commercial extracts. Phospholipids: lecithin-type compounds (~3–5mg/g). Tannins and proanthocyanidins: catechin and epicatechin derivatives (~5–15mg/g). Minerals: iron (~12–18mg/100g dried root), zinc (~2–4mg/100g), manganese (~3–6mg/100g), calcium (~80–120mg/100g). Fiber: crude fiber approximately 8–12% of dried root weight, primarily insoluble. Protein: approximately 4–7% of dried weight, nutritionally insignificant at supplemental doses. Bioavailability notes: THSG has moderate oral bioavailability (~20–40%), enhanced by gut microbiota conversion to aglycone forms; anthraquinones are poorly absorbed but active in the colon; fat-soluble stilbenes benefit from co-administration with dietary fats; prepared (Zhi) form alters the phytochemical ratio, reducing hepatotoxic anthraquinone fractions while retaining THSG levels.
How It Works
Mechanism of Action
TSG and emodin increase superoxide dismutase and catalase activity in liver cells, reducing oxidative stress. The stilbene compounds enhance microcirculation by promoting nitric oxide release in blood vessels. These mechanisms improve nutrient delivery to hair follicles and support hepatic detoxification pathways.
Clinical Evidence
Limited human studies exist for He Shou Wu, with most research conducted in animal models. A 12-week study in 60 participants showed modest improvements in hair density compared to placebo. Animal studies demonstrate significant increases in antioxidant enzyme levels and hair follicle proliferation. Clinical evidence remains preliminary and requires larger human trials for definitive efficacy claims.
Safety & Interactions
He Shou Wu may cause hepatotoxicity in sensitive individuals, particularly with long-term use or high doses. It can interact with warfarin and other anticoagulants due to its blood-thinning properties. Gastrointestinal upset, including nausea and diarrhea, occurs in some users. Pregnant and breastfeeding women should avoid use due to insufficient safety data.

Frequently Asked Questions
How much He Shou Wu should I take daily?
Traditional dosing ranges from 3-6 grams of raw root daily or 1-3 grams of prepared extract. Start with lower doses to assess tolerance, as higher amounts may cause digestive upset or liver stress.
How long does He Shou Wu take to work for hair growth?
Visible hair improvements typically require 3-6 months of consistent use, as hair follicle cycles are naturally slow. Clinical studies showing hair density improvements used treatment periods of at least 12 weeks.
Can He Shou Wu cause liver damage?
Yes, He Shou Wu has been associated with hepatotoxicity in some cases, particularly with prolonged use or poor-quality preparations. Regular liver function monitoring is recommended during extended supplementation periods.
What's the difference between raw and prepared He Shou Wu?
Raw He Shou Wu is more likely to cause digestive upset and liver toxicity, while prepared (processed with black bean juice) forms are considered safer and more tonifying. Traditional Chinese medicine typically uses the prepared form for health benefits.
Does He Shou Wu interact with blood thinning medications?
He Shou Wu may enhance anticoagulant effects of warfarin and similar medications, potentially increasing bleeding risk. Consult healthcare providers before combining with any blood-thinning drugs or before surgical procedures.
Is He Shou Wu safe during pregnancy and breastfeeding?
He Shou Wu is traditionally not recommended during pregnancy due to limited safety data and its potent effects on circulation and hormonal balance. Pregnant and breastfeeding women should consult their healthcare provider before using this ingredient, as it may affect fetal development or pass into breast milk. It is best to avoid supplementation during these critical periods.
What does scientific research show about He Shou Wu's effectiveness for hair loss?
While He Shou Wu has been used in Traditional Chinese Medicine for centuries to support hair health, most clinical evidence remains limited to small-scale or animal studies. Research suggests its antioxidant and blood circulation-enhancing properties may support hair follicle function, but large-scale human trials are needed to confirm efficacy. Current evidence supports its traditional use, though results vary individually.
Who should avoid He Shou Wu supplementation?
People with liver disease, those taking anticoagulant medications, pregnant or breastfeeding women, and individuals with known allergies to Polygonaceae family plants should avoid He Shou Wu. Children and the elderly should only use this ingredient under professional guidance due to its potent effects on liver and kidney function. Those with gastrointestinal sensitivity may experience digestive upset and should start with lower doses.
