The best way to describe the smell of camphene is fir needles, musky earth, and damp woodlands. Camphene aroma is often mistaken with myrcene, which is that trademark marijuana smell as most of us know it. From the medical point of view, camphene has great potential. When mixed with vitamin C, it becomes a powerful antioxidant. It is widely used in conventional medicine as a topical for skin issues like eczema and psoriasis.
Camphene is a bicyclic organic compound. It is one of the most pervasive monoterpenes. As with other terpenes, it is insoluble in water, flammable, colorless, and has a pungent smell. It is a minor constituent of many essential oils such as turpentine, cypress oil, camphor oil, citronella oil, neroli, ginger oil, valerian, and mango. It is produced industrially by isomerization of the more common alpha-pinene using a solid acid catalyst such as titanium dioxide.
