Camphor is extracted from the trunk of camphor tree. The longer the tree is, the more camphor it is rich in. The refining method is to cut the trunk into small pieces and distill it with water. When camphor oil is heated, it will rise with water vapor, and then contact with the earthenware pot placed on it, and form camphor after cooling.
