Safety Notes

It is likely safe for most adults to take a small amount of myrrh for a short time and use it on the skin, but it may make your skin dry.B1 Large amounts may be unsafe. Not enough studies have been done to say whether it is safe to use for a long period. Myrrh should not be taken during pregnancy or when breastfeeding.


Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse.
