It is also used for treating sore throat and mouth, menstrual cramps, cancer and stomach and duodenal ulcers.
In one small study of about 250 women undergoing radiation therapy after surgery for breast cancer, a commercial calendula ointment reduced the amount of skin irritation better than another commonly-used commercial preparation. Women who used the calendula ointment also reported less pain from the radiation. Investigations into anti-cancer and anti-viral actions continue.
