CBD, or cannabidiol, is one of the molecules found in cannabis compounds. Unlike the more known THC molecule, CBD does not cause a high. It is a type of a cannabinoid, a chemical that binds to neuroreceptors in the body’s endocannabinoid system (ECS).

Research is still being done to find how effective CBD is for treating mental illnesses, but the findings show potential for treating conditions like OCD, anxiety, and even post-traumatic stress disorder. It has been used successfully in controlling the frequency and severity of convulsive epileptic seizures. It may even help sufferers of autoimmune disorders by suppressing the immune system.

Cannabidiol can be extracted from two plants: marijuana and hemp. While these plants are closely related, hemp does not have anywhere near as much THC as marijuana, even though it can have similar levels of CBD. Cannabis can be bred in order to lower THC and have much higher levels of CBD.
