Apart from the cannabinoids CBD, CBC, and CBG, terpenes also show promise to kill fungi. The terpene Beta-caryophyllene is very effective against a toenail fungus that could be very resistant to other treatments. When the fungus lies under the toenail surface between the nail layers, it can be very hard to control and destroy it. Beta-caryophyllene works very much like other anti-fungus treatments, but with less harm done. The treatment period is also shorter as it reaches deeply into the affected areas. Conventional creams do not succeed in this.
