Goldenseal is widely used in many herbal salves and ointments as a disinfectant. The root contains berberine and hydrastine which give goldenseal a broad-spectrum antibacterial action. Goldenseal is often thought of in the same vein as echinachea, an immune booster to take at the onset of a cold, but this is mistaken. The herb's real value is as a topical antibioctic in skin infections sore throats, and other applications where it comes in direct contact witht the affected areas.
