Scullcap taken by mouth has been used to treat arthritis, lung problems, hay fever, seizures, HIV or AIDS, and hepatitis. Scullcap applied to the skin has been used to treat psoriasis, sores or swelling, and hemorrhoids. However, scullcap has not been proven with research to be effective in treating these conditions.

Scullcap is often sold as an herbal supplement. There are no regulated manufacturing standards in place for many herbal compounds and some marketed supplements have been found to be contaminated with toxic metals or other drugs.
