Cannabidiol or CBD is a naturally occurring component of cannabis extracted from the cannabis plant. CBD is not psychoactive and does not produce the ‘high’ of THC (tetrahydrocannabinol). All cannabinoids, including CBD, produce effects in the body by attaching to receptors in the brain or immune system. The human body has an endocannabinoid system (ECS) that produces some cannabinoids of its own and receives and translates signals from cannabinoids. The ECS helps to regulate functions such as sleep, immune-system responses and pain. CBD directs the body to use more of its own cannabinoids to produce the therapeutic effects associated with CBD.
