Self-heal is an herb. The parts that grow above the ground are used to make medicine.

Self-heal is used for inflammatory bowel disease such as Crohn disease and ulcerative colitis, rheumatoid arthritis, problems in the stomach and intestines, sore throat, and other conditions, but there is no good scientific evidence to support these uses.

Be careful not to confuse self-heal with another plant called sanicle. Sanicle is sometimes referred to as self-heal, but it's different.
When taken by mouth: There isn't enough reliable information to know if self-heal is safe. It might cause upset stomach and diarrhea.
