Description

People use camphor topically to relieve pain and reduce itching. It has also been used to treat fungal infections of the toenail, warts, cold sores, hemorrhoids, andosteoarthritis. Camphor is used topically to increase local blood flow and as a “counterirritant,” which reduces pain and swelling by causing irritation. It is important not to apply camphor to broken skin, because it can enter the body quickly and reach concentrations that are high enough to cause poisoning.
