CO2 extraction is one of the most common ways CBD is extracted from the hemp or cannabis plants. This method uses expensive equipment that adjusts temperature and pressure to extract the cannabinoids from the plant material, without damaging them. The other common method is to use solvents like ethanol or butane to extract the plant material. These solvents have to be burned off the final product which may damage the cannabinoids or terpenes in the process. There is also a risk that these solvents may not have burned off completely and could end up in your end product.
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.
