Camphor

Description

Camphor is a powder that originally came from the bark and wood of the camphor tree. Camphor is commonly applied as a topical medication as a skin cream or ointment to relieve itching from insect bites, minor skin irritation, or joint pain. It is absorbed in the skin epidermis, where it stimulates nerve endings sensitive to heat and cold, producing a warm sensation when vigorously applied, or a cool sensation when applied gently. The action on nerve endings also induces a slight local analgesia.
