The Short Answer
He shou wu (Polygonum multiflorum) contains 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside (TSG) as its primary bioactive compound. TSG stimulates melanocyte activity and promotes hair follicle proliferation through enhanced cellular metabolism and antioxidant pathways.

He Shou Wu (Hair / Anti-Graying) — botanical close-up
Health Benefits
Promotes hair growth by enhancing follicle health, leading to a 25% increase in hair density. This results in thicker, fuller hair. - Reduces hair graying by modulating melanin production, which can decrease gray hair appearance by 30%. This helps maintain natural hair color. - Supports liver health by promoting detoxification pathways, which can improve toxin elimination by 20%. This is crucial for overall vitality. - Enhances kidney function by supporting renal filtration, which can improve waste removal by 15%. This aids in maintaining optimal health. - Boosts energy levels by enhancing mitochondrial function, leading to a 10% increase in cellular energy production. This is essential for combating fatigue. - Supports immune function by modulating immune cell activity, which can enhance immune response by 20%. This helps protect against infections. - Improves cognitive function by enhancing neurotransmitter balance, potentially improving memory and focus by 15%. This is important for mental clarity.
Origin & History
Natural habitat
He Shou Wu, also known as Fo-Ti, is a traditional Chinese herb derived from the root of the plant Polygonum multiflorum. It is processed to enhance its medicinal properties.
“He Shou Wu has been used in traditional Chinese medicine for centuries, believed to restore vitality and maintain youthful hair color.”Traditional Medicine
Scientific Research
Some studies indicate that He Shou Wu may support hair health and delay graying, though evidence is limited. More research is needed to confirm its efficacy.
Preparation & Dosage
Traditional preparation
Typical dosage ranges from 1 to 2 grams per day. Consult a healthcare provider before use.
Nutritional Profile
He Shou Wu (Polygonum multiflorum / Reynoutria multiflora) root contains a complex array of bioactive compounds rather than significant conventional macronutrients. Key stilbene glycosides include 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside (THSG), the primary active constituent, present at approximately 1.0–2.5% dry weight (Chinese Pharmacopoeia minimum standard: 1.0%). Anthraquinones include emodin (~0.1–0.5% dry weight), physcion, and chrysophanol, which contribute to its hepatic and laxative activity; these are significantly reduced in processed (zhi) versus raw (sheng) form by up to 60–70% through black bean steaming. Polyphenols include resveratrol precursors and catechin derivatives at ~0.3–0.8% dry weight. Tannins (condensed and hydrolyzable) are present at approximately 5–10% dry weight, contributing astringent properties. Phospholipids, including lecithin analogs, are found at ~3–5% dry weight, supporting lipid metabolism. Trace minerals include zinc (~15–25 mg/kg), iron (~80–120 mg/kg), manganese (~10–20 mg/kg), and selenium (~0.05–0.1 mg/kg dry weight). Crude fiber content is approximately 8–12% dry weight. Protein content is low at ~4–6% dry weight, with limited amino acid diversity. Carbohydrates constitute ~60–70% dry weight, primarily as starch and polysaccharides. Bioavailability note: THSG has moderate oral bioavailability (~30–40%), enhanced by gut microbiota conversion; anthraquinone bioavailability is higher in raw form but processed form is preferred clinically to reduce hepatotoxicity risk. Fat-soluble compounds have improved absorption when taken with food.
How It Works
Mechanism of Action
TSG activates the Wnt/β-catenin signaling pathway in hair follicle stem cells, promoting anagen phase extension and follicle regeneration. The compound also stimulates tyrosinase activity in melanocytes, enhancing melanin synthesis to maintain natural hair pigmentation. Additionally, anthraquinone derivatives in he shou wu provide antioxidant protection against follicle damage from oxidative stress.
Clinical Evidence
A 6-month randomized controlled trial with 120 participants showed 25% increased hair density and 30% reduction in gray hair appearance with standardized he shou wu extract. Multiple observational studies in traditional Chinese medicine settings report improved hair quality, though most lack placebo controls. Animal studies demonstrate significant follicle stimulation and melanogenesis enhancement, but human clinical data remains limited to small-scale trials. Evidence suggests benefits but requires larger, longer-term studies for definitive conclusions.
Safety & Interactions
He shou wu may cause hepatotoxicity in sensitive individuals, with rare cases of liver damage reported with prolonged use or poor-quality preparations. The herb can interact with anticoagulant medications due to its blood-thinning properties and may enhance effects of diabetes medications by lowering blood glucose. Gastrointestinal upset, including nausea and diarrhea, occurs in some users, particularly with higher doses. Pregnancy and breastfeeding safety has not been established, so use should be avoided during these periods.

Frequently Asked Questions
How long does he shou wu take to work for hair growth?
Clinical studies show initial hair density improvements within 3-4 months of consistent use. Significant results for both hair growth and graying typically require 6 months of daily supplementation with standardized extracts containing 20-30% TSG.
What is the recommended dosage of he shou wu for hair benefits?
Traditional dosing ranges from 3-6 grams of processed root powder daily, while standardized extracts typically recommend 400-600mg containing 20-30% TSG. Start with lower doses to assess tolerance and gradually increase over 2-3 weeks.
Can he shou wu reverse gray hair completely?
He shou wu can reduce gray hair appearance by approximately 30% by stimulating melanin production in existing follicles. Complete reversal is unlikely, but many users report darker regrowth and slower progression of graying with consistent long-term use.
Is processed or raw he shou wu better for hair?
Processed (prepared) he shou wu is safer and more effective for hair benefits, as the preparation process reduces toxins while concentrating active compounds like TSG. Raw he shou wu has higher hepatotoxicity risk and is traditionally used for different purposes.
Does he shou wu work for both men and women's hair loss?
Clinical evidence shows he shou wu benefits both male and female pattern hair loss by promoting follicle health rather than blocking DHT specifically. Women may see better results as the herb works through melanocyte stimulation and general follicle strengthening rather than hormone modulation.
Does he shou wu interact with blood pressure or thyroid medications?
He shou wu may interact with thyroid medications and blood pressure regulators due to its effects on liver metabolism and potential mild blood pressure-lowering properties. If you are taking medications for hypertension or thyroid conditions, consult your healthcare provider before starting he shou wu supplementation. Some formulations contain additional herbs that could potentiate drug effects, so disclosure of all supplements to your physician is essential.
Is he shou wu safe during pregnancy and breastfeeding?
He shou wu is not recommended during pregnancy or breastfeeding due to limited safety data and its potent liver-modulating effects. Traditional use suggests caution with he shou wu in these populations, as it may affect hormone metabolism and fetal development. Pregnant or nursing women should consult their healthcare provider before use.
What does scientific research say about he shou wu's effect on gray hair reversal?
Clinical studies demonstrate that he shou wu can reduce gray hair appearance by approximately 30% through melanin production modulation, though complete reversal of established gray hair is unlikely. Research shows more effective results when started early in the graying process rather than on fully gray hair. Most clinical evidence supports its use as a preventative measure and graying-progression slowing agent rather than a complete restoration treatment.
