Did you know? Its name comes from a legend about a man named He whose hair turned black after he took the root.

What it may help, and how strong the proof is

  • Hair & nails. Traditional use for graying hair. Some lab and cell studies exist. No good human trials show darker hair.
    Traditional proof
  • Cholesterol. Lab and animal studies suggest lower cholesterol. Human proof is limited, and the liver risk is serious.
    Traditional proof
  • Liver. The popular claim that it protects the liver is not supported. The herb is more often linked to liver injury.

Chinese medicine
何首乌 Tonify blood. Nature: warm. Flavour: bitter, sweet, astringent. Enters the Liver, Heart and Kidney channels.

How people take it

Traditional use calls for steamed (processed) root. Commercial doses vary widely and are not standardized. No dose has been shown to be safe, and the liver injury does not clearly follow a set dose.

Decoction, powder, capsule and tincture.

Where to get it

Grows wild and is cultivated in China, Korea and Japan. Sold as raw or steamed root slices, powder, capsules and tinctures. Raw root is considered more toxic than steamed root in traditional texts, which is not a reason to use it.

Be careful

Serious liver injury has been reported, including deaths and some cases needing liver transplant. Symptoms can start days to months after use: dark urine, yellow skin or eyes, nausea, fatigue and belly pain. Stop it at once if these appear and get medical care.

Avoid if: liver disease; pregnancy; breastfeeding; heavy alcohol use.

Mixing with other things

  • Don't mix
    Alcohol (beer, wine, spirits)

    Alcohol adds to liver stress. Together, the two raise the risk of serious liver damage.

  • Use caution
    Statins (Lipitor, Zocor, Crestor)

    Both can stress the liver. Combining them may add risk, so check with a clinician and get liver tests.

The honest take

Fo-ti is one of the most important herb-related causes of liver injury in Chinese reports. Its claims for darker hair and lower cholesterol have little human proof. Given the liver risk, the honest choice is to avoid it.
