Overview
Camphor is a chemical that used to be made by distilling the bark and wood of the camphor tree. Today, camphor is usually made from turpentine oil.
Camphor has a very distinct smell. It seems to stimulate nerves and help with symptoms such as pain and itching. In the nose, camphor seems to create a cold sensation so that breathing feels easier. It's used in products such as Vicks VapoRub.
People use camphor for cough, pain, and itching. It is also used for insect bites, acne, and many other conditions, but there is no good scientific evidence to support most of these uses.
Taking camphor by mouth is unsafe. Camphor products include camphorated oil or camphorated spirits. Camphorated oil was removed from the US market in the 1980s due to accidental poisonings.

When applied to the skin: Camphor is possibly safe when used in a cream or ointment in concentrations ranging from 0.1% to 11%, short-term. Side effects might include skin redness and irritation. But camphor is likely unsafe when used on broken skin. Camphor is easily absorbed through broken skin and can reach toxic levels.
