Fo-ti

Also known as: Polygonum multiflorum, he shou wu

Fo-ti is the root of Polygonum multiflorum, used in traditional Chinese medicine for "rejuvenation" and against greying hair. Reliable evidence is lacking and there are repeated reports of liver injury.

What it is used for

  • slowing greying and supporting hair growth – no reliable evidence
  • longevity and vitality – no human evidence

Forms and how they differ

processed root

traditionally prepared root; processing does not rule out liver risk

raw root and extracts

laxative effect, risk of liver injury

When to take it

If you take it anyway, only short term with food and as the label says.

Pairs well with

For hair, rather proven steps: check iron, thyroid, B12 and vitamin D.

Do not combine / separate

Do not combine with other liver-burdening substances (alcohol, high-dose paracetamol, other herbal extracts) or with blood thinners and diabetes medicines.

Watch out for

Not suitable in pregnancy, breastfeeding, with liver disease or for children. If you take medicines, consult your doctor; seek medical help for jaundice, dark urine or nausea.

Safety

Liver injury has been reported even at usual doses; do not exceed the label dose.

Practical tip

With this supplement the risk probably outweighs the benefit – consider whether you really need it.
