Derived from a wood, Camphor crystals are acrid and hot in energy, and are only to be used externally. This herb interacts with the Heart meridian. Its strong scent is pleasing to some and offensive to others.
Being one of the primary ingredients in a variety of commercial analgesic balms, camphor invigorates the Blood and reduces inflammation. It is used in certain recipes for topical application to traumatic injury and stagnation of Blood. While it is naturally ocurring in a number of trees, it can also be produced via the oxidation of Borneol in a laboratory setting.
