Uses

Camphor is a rubefacient -- it relieves mild pain and itching, and creates inflammation and redness when rubbed into the skin. It has a cooling effect when applied to the skin, much like menthol.

Camphor is used in acne medications, cough remedies, ear drops, and other medications where its ability to soothe the skin helps it to undo the effects of other ingredients that might otherwise be irritants.
