Safety Notes

It is likely safe for most adults to use dong quai on the skin and to take it orally in small doses for a short time. Dong quai may not be safe for pregnant women. Not enough studies have been done to say whether it is safe to use for a long period or by women who are breastfeeding.

Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse such as:
  • People taking medicine for anxiety should talk to their doctor before taking dong quai. It may interact with the medicine.
