The roots of the goldenseal plant (Hydrastis canadensis) are used to make products that are widely consumed as medicines. Goldenseal products are promoted as a means to self-treat respiratory tract infections, digestive issues, and skin irritation like rashes. Research on the plant’s medicinal use is limited, but some studies suggest that goldenseal can interact with certain pharmaceutical medications and produce unintended effects.
