How Is CBD Oil Made?

The two most common ways to make CBD oil are alcohol extraction and CO2 extraction.

Alcohol extraction involves soaking the hemp plant in a solvent such as ethanol: the solvent leeches out the CBD and other cannabinoids from the plant.

The alcohol solution is then heated, which causes evaporation. The heat doesn’t damage the cannabinoids. So, the residue after evaporation is an oil rich in cannabinoids.

The CO2 method involves forcing carbon dioxide (CO2) through the hemp plant. This action, done through temperature and pressure changes within chambers of
specialized equipment. The CO2 causes the cannabinoids to separated from the plant and allow collection in the various chambers of the equipment.

Both methods can produce high -quality CBD oil. But some people believe the CO2 method can improve purity. Because of the way different cannabinoids are capture in separate chambers. That, in turn, makes it easier to control the ratio of CBD to other cannabinoids.

How CBD works

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.

Researchers once believed that CBD attached to these CB2 receptors, but it now appears that CBD does not attach directly to either receptor.

Instead, it seems to direct the body to use more of its own cannabinoids.
