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.
Tribulus terrestris is a fruit-producing Mediterranean plant that's covered with spines. It is also called puncture vine.
People use the fruit, leaf, or root of the tribulus plant as medicine. Some formulations also include other ingredients.
