Cannabidiol (CBD) is one of at least 113 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 wide scope of potential medical applications, due to clinical reports showing the lack of side effects, particularly its low psychoactivity (as is typically associated with ?9-THC), and non-interference with several psychomotor learning and psychological functions.
All cannabinoids, including cannabidiol (CBD), attach themselves to certain receptors in the body to produce their effects. The human body produces certain cannabinoids on its own. It has two receptors for cannabinoids, called CB1 receptors and CB2 receptors. CB1 receptors are found all around the body, but many of them are in the brain.
The CB1 receptors in the brain deal with coordination and movement, pain, emotions and mood, thinking, appetite, and memories, among others. THC attaches to these receptors. CB2 receptors are more common in the immune system. They have an effect on inflammation and pain. It used to be thought that CBD acts on these CB2 receptors, but it appears now that CBD does not act on either receptor directly. Instead, it seems to influence the body to use more of its own cannabinoids.
