Camphor is a powder that originally came from the bark and wood of the camphor tree.
Today, most camphor is synthetic. It's in some products that are applied to the skin, including FDA-approved treatments. It's a common ingredient in remedies applied to the skin for cough and skin irritation.
Emu oil comes from the fat of the emu, a large, flightless, Australian bird. People farm emu in the U.S. for their meat, leather, and oil. Aboriginal Australians used emu oil as a treatment for pain and injuries.
There's some evidence that a cream containing camphor as well as two other ingredients may help with osteoarthritis symptoms.
