Cannabidiol (CBD) is one of at least 85 active cannabinoids identified in cannabis. It is a major phytocannabinoid, accounting for up to 40% of the plant’s extract. CBD is considered to have a wider scope of medical applications than tetrahydrocannabinol (THC). An orally-administered liquid containing CBD has received orphan drug status in the US, for use as a treatment for Dravet syndrome, under the brand name Epidiolex.
