For centuries, women have coveted lustrous, healthy black hair. However, the stresses of modern life have led to an increase in hair-related issues such as premature greying and hair loss. Today, I’d like to share a traditional folk remedy for these concerns: the herb Fallopia multiflora, commonly known as Chinese climbing knotweed or he shou wu.
He Shou Wu: Nature’s Treasure
According to TS.BS Nguyen Thi Bay of Ho Chi Minh City University of Medicine and Pharmacy, he shou wu (scientific name: Polygonum multiflorum) is a valuable medicinal herb that has been used for thousands of years in traditional medicine. This climbing plant has heart-shaped leaves and small white flowers. Its distinctive feature is its brown-red tuber, which is the part used for medicinal purposes.
In Vietnam, he shou wu is predominantly found in the northern mountainous provinces of Lao Cai, Yen Bai, and Son La. For generations, Vietnamese have utilized he shou wu to enhance overall health, promote hair growth, and prevent hair loss. Traditional doctors often combine he shou wu with Rehmannia glutinosa and wolfberries to create a renowned tonic for blood and kidney health.

The Amazing Benefits of He Shou Wu
When it comes to hair care, he shou wu contains anthraquinone, which stimulates blood circulation in the scalp, providing essential nutrients to hair follicles. Research by the Institute of Medicinal Materials has also shown that he shou wu promotes melanin production, influencing hair color.
Beyond its benefits for hair, he shou wu is renowned for its liver and kidney-supportive properties. ThS.BS Hoang Khanh Toan of the 108 Military Central Hospital states, “He shou wu enhances liver function, aids in detoxifying the body, and improves kidney function effectively.”
Additionally, modern studies indicate that he shou wu can lower bad cholesterol and triglyceride levels in the blood, contributing to cardiovascular health. However, optimal results are achieved when combined with a healthy diet and regular exercise.
Safe and Effective Usage
He shou wu is available in two main varieties: red and white. The red variety is considered more potent medicinally. It can be consumed fresh, dried, powdered, or infused in alcohol. The typical dosage is 10-20g per day, preferably taken after meals.
Here are a few simple recipes:
- He shou wu alcohol infusion: Soak 500g of dried roots in 2 liters of 40% alcohol for 3 months.
- Decoction: Simmer 20g of he shou wu in 1 liter of water until reduced to 300ml.

Precautions
Despite being a natural herb, he shou wu may not be suitable for everyone. Pregnant and breastfeeding women, as well as individuals with autoimmune conditions, should exercise caution. Some possible side effects include diarrhea and indigestion.
TS.BS Pham Hung Cung advises, “It is important to select high-quality he shou wu from a reputable source. Store it in a cool, dry place to preserve its medicinal properties.”
Conclusion
He shou wu is indeed a precious gift from nature for health and beauty. However, to maximize its benefits, it should be used appropriately and under the guidance of a healthcare professional. Listen to your body and always consult with experts before incorporating new herbs into your routine.
