Fo-Ti (He Shou Wu): The ancient herb for modern wellness

Traditional Chinese medicine setup featuring herbs, also Fo-Ti, acupuncture needles, a glass cupping jar, and a book with Chinese text, evoking calmness.

In the world of herbal medicine, few plants are as steeped in legend and tradition as Fo-Ti (scientific name: Polygonum multiflorum, also called He Shou Wu). For centuries, Fo-Ti has been used in Traditional Chinese Medicine (TCM) as a revered tonic for promoting longevity, youthful energy, and vibrant hair.

But what does modern science say? Can this ancient root really live up to its legendary reputation? Let’s dive into the history, potential benefits, scientific studies, and important safety information you need to know about Fo-Ti.


A brief history of Fo-Ti

Fo-Ti’s story dates back over 1,000 years to a Chinese legend about an old man named He Shou Wu. According to folklore, he discovered the root and experienced dramatic improvements in his health — reversing his aging, restoring his black hair, and even fathering many children in his later years. Ever since, He Shou Wu has been associated with vitality, longevity, and vigor.

In TCM, Fo-Ti is categorized as a "yin tonic", traditionally used to:

  • Nourish the blood and liver

  • Strengthen the kidneys

  • Promote hair growth and color

  • Boost reproductive health

  • Enhance general vitality and lifespan


Potential health benefits of Fo-Ti (backed by science)

While much of Fo-Ti’s fame stems from traditional use, modern research has begun to explore its health-promoting properties. Here are some of the key benefits that have been studied:


  1. Supports hair growth and restores hair color

One of Fo-Ti’s most famous claims is its ability to promote hair growth and reverse graying. In a 2015 animal study published in BMC Complementary and Alternative Medicine, researchers found that extracts of Polygonum multiflorum promoted hair growth in mice by stimulating the anagen phase (active growth phase) of hair follicles.

Lin, W. H., et al. (2015). "Polygonum multiflorum extract promotes hair growth through inducing the anagen phase in telogen mouse skin." BMC Complementary and Alternative Medicine.

Although human studies are still limited, Fo-Ti remains a popular ingredient in hair tonics and supplements targeting hair vitality.



  1. May enhance liver and kidney health

In TCM, the liver and kidneys are vital organs tied to aging and vitality. Modern studies have shown that processed Fo-Ti (known as Zhi He Shou Wu) may have hepatoprotective effects. A 2012 study in Phytotherapy Research demonstrated that properly prepared Fo-Ti had antioxidant properties that protected liver cells from damage in rats exposed to oxidative stress.

Zhu, Y., et al. (2012). "Protective effects of processed Polygonum multiflorum on oxidative stress injury in rat liver." Phytotherapy Research.

⚠️ However, unprocessed or improperly processed Fo-Ti has been associated with liver toxicity in some cases (more on safety below).


  1. Boosts antioxidant activity

Fo-Ti is rich in stilbenes, flavonoids, and other antioxidant compounds that help combat oxidative stress — a major contributor to aging and chronic diseases.A 2006 study in Archives of Pharmacal Research identified Fo-Ti’s strong antioxidant capacity, suggesting its potential role in anti-aging therapy.

  1. Potential anti-inflammatory properties

Chronic inflammation is at the root of many health issues, including arthritis, cardiovascular disease, and neurodegeneration.Research published in the Journal of Ethnopharmacology (2010) showed that Fo-Ti extracts could significantly reduce markers of inflammation in animal models.

Reference:

Zhou, Y. X., et al. (2010). "Anti-inflammatory effects of a processed form of Polygonum multiflorum in rats." Journal of Ethnopharmacology.

How to use Fo-Ti

Fo-Ti is available in several forms:

  • Capsules and tablets (e.g., NOW Fo-Ti)

  • Powdered root (for teas or smoothies)

  • Tinctures

  • Topical preparations (for scalp or hair care)

In TCM, Fo-Ti is often "prepared" by steaming it with black beans, which is believed to enhance its tonic properties and reduce potential toxicity.

Typical Dosage: While dosage recommendations can vary, common amounts range from 250mg to 1.000mg daily when using capsules. Always follow the manufacturer's guidelines or consult a qualified health professional.


Safety and side effects

While Fo-Ti offers exciting potential benefits, safety is a major consideration.Unprocessed Fo-Ti, or excessive intake, has been linked to serious liver damage, including cases of hepatitis and liver failure.

A review in Frontiers in Pharmacology (2019) highlighted several case reports of Fo-Ti-induced liver toxicity, especially when unprocessed products were consumed at high doses.

Reference:

Zhou, X., et al. (2019). "A comprehensive review on hepatotoxicity of herbal medicines: Clinical characteristics, mechanisms and current challenges." Frontiers in Pharmacology.

Tips for safe use:

  • Choose prepared or processed Fo-Ti from reputable brands (like NOW Foods).

  • Stick to recommended dosages.

  • Avoid use if you have pre-existing liver issues.

  • Consult a healthcare provider before starting, especially if you’re on medications or have chronic conditions.



Final thoughts: Is Fo-Ti right for you?

Fo-Ti remains one of the most fascinating herbs in the wellness world — offering potential benefits for hair health, energy, longevity, and vital organ support. Backed by both tradition and growing scientific interest, it’s an herbal powerhouse worth considering.

However, because of potential safety risks, especially regarding liver health, it’s crucial to choose high-quality, properly prepared supplements and consult your healthcare provider before beginning any new regimen.

Nature’s wisdom is powerful — but it’s even better when balanced with informed choices!
