Myrrh is a yellow, fragrant, sap-like resin that comes out of cuts in the bark of certain Commiphora trees, including the Commiphora myrrham tree.

Myrrh contains chemicals that might reduce pain and kill bacteria. It's used worldwide but is especially popular in China and Egypt.

People use myrrh for back pain, diarrhea, parasite infections, wound healing, and many other conditions, but there is no good scientific evidence to support these uses. There is also no good evidence to support using myrrh for COVID-19.

Don't confuse myrrh with guggul. These are related but not the same.
When taken by mouth: Myrrh is commonly consumed in foods as a flavoring agent. Myrrh is possibly safe when used as medicine in doses of 400 mg three times daily for up to 12 months. It's usually well-tolerated. But taking large doses of myrrh is possibly unsafe. Doses greater than 2-4 grams can cause kidney problems and heart rate changes.

When applied to the skin: Myrrh is possibly safe for most people. It's been used safely in a diluted bath for up to 7 days. It might cause a skin rash in some people.

Special Precautions & Warnings:

Pregnancy: Myrrh is likely unsafe when taken by mouth during pregnancy. Myrrh can stimulate the uterus and might cause a miscarriage. There isn't enough reliable information to know if myrrh is safe to use on the skin when pregnant. Stay on the safe side and avoid use.

Breast-feeding: There isn't enough reliable information to know if myrrh is safe to use when breast-feeding. Stay on the safe side and avoid use.

Surgery: Myrrh might affect blood sugar levels. This might interfere with blood sugar control during and after surgery. Stop using myrrh at least 2 weeks before a scheduled surgery.
