Description: Cannabidiol, also know as CBD, is discontinued (DEA controlled substance). It is a major phytocannabinoid, accounting for up to 40% of the plant's extract. CBD is considered to have a wider scope of potential medical applications than tetrahydrocannabinol (THC). Cannabidiol has been listed in the European Commission Cosmetics Ingredient Database with four functional claims: antioxidant, antiseborroeic, skin conditioning, and skin protecting.
