What does the research say?

Traditional use

These are traditional uses, not proven treatments.

  • Bai zhi is described as pungent and warm, and has been used in China for centuries, alone or in formulas, for:

    • Colds and fever, headache and forehead pain
    • Blocked nose, sinusitis and nosebleeds
    • Toothache
    • Aches from "cold and damp"
    • Vaginal discharge

    On the skin it's used for boils, sores and painful swellings. In Korea and Japan it's used for colds, headache and rhinitis, and in Japan also for acne and skin rashes. It's also made into teas.[1]

Laboratory & animal research

Lab and animal results show what might be worth studying in people. They don't show that the herb has these effects in humans.

  • In lab and animal studies, the root and its coumarins (especially imperatorin) relieved pain, may help reduce inflammation, slowed tumours, killed microbes and protected nerves and the liver. These haven't been confirmed in people.[1]

In short

Toxicity studies are lacking.
