In addition, CBD oil can be extracted and manufactured through “supercritical CO2 extraction.” This process involves using carbon dioxide under high pressure in an extremely cold environment. Supercritical CO2 extraction requires expensive equipment, more complex refinement process and production expertise, but it ensures that CBD oil maintains its purity all through the process.
Cannabidiol (CBD) is one of dozens of non-psychoactive cannabinoids found in the hemp plant. Cannabidiol, and all the other cannabinoids, were patented by the United States Government in 2003 as neuroprotectants and antioxidants (Patent No. 6,630,507). Cannabinoids are characterized by their ability to act on the cannabinoid receptors that are found throughout the body. CBD and other cannabinoids are naturally occurring compounds that display potent anti-inflammatory and pain-relieving properties. They can promote the body’s healthy regulation of the central nervous, immune, and endocannabinoid systems.
