Where does CBD come from?
The least processed form of the cannabis plant is hemp. Hemp contains most of the CBD that people use medicinally. Hemp and marijuana come from the same plant, Cannabis sativa, but the two are very different.
Over the years, marijuana farmers have selectively bred their plants to contain high levels of THC and other compounds that interested them, often because the compounds produced a smell or had another effect on the plant’s flowers.
However, hemp farmers have rarely modified the plant. These hemp plants are used to create CBD oil.
How does CBD work?
All cannabinoids, including CBD, produce effects in the body by attaching to certain receptors.
The human body produces certain cannabinoids on its own. It also has two receptors for cannabinoids, called the CB1 receptors and CB2 receptors.
CB1 receptors are present throughout the body, but many are in the brain.
The CB1 receptors in the brain deal with coordination and movement, pain, emotions, and mood, thinking, appetite, and memories, and other functions. THC attaches to these receptors.
CB2 receptors are more common in the immune system. They affect inflammation and pain.
