Does It Matter Which Part Of the Marijuana Plant My CBD Oil Comes From
“CBD is CBD—It doesn’t matter where it comes from.” Yes it does matter. The flower-tops and leaves of some industrial hemp strains may be a viable source of CBD (legal issues notwithstanding), but hemp Flowers and Leaves is by no means an optimal source of cannabidiol. Industrial hemp typically contains far less cannabidiol than CBD-rich cannabis. Huge amounts of industrial hemp are required to extract a small amount of CBD, thereby raising the risk of toxic contaminants because hemp is a “bio-accumulator” that draws heavy metals from the soil. Single-molecule CBD synthesized in a lab or extracted and refined from industrial hemp lacks critical medicinal terpenes and secondary cannabinoids found in cannabis strains. These compounds interact with CBD and THC to enhance their therapeutic benefits.
When looking at CBD and Hemp Oil Label Look for “Cannabis Sativa (Hemp seed Oil)”
Safe and effective ways to extract and produce CBD-rich cannabis oil.
To extract CBD-rich cannabis oil, one must start with CBD-rich plant material. There are many ways to extract oil from the cannabis plant, each has its pros and cons. Some methods are safer and more effective than others. Cannabis oil made with neurotoxic solvents like butane and hexane may leave unsafe residues that compromise immune function and impede healing.
- CO2 extraction. The supercritical (or subcritical) CO2 method uses carbon dioxide under high pressure and extremely low temperatures to isolate, preserve, and maintain the purity of the medicinal oil. This process requires expensive equipment and a steep operational learning curve. But, when done well the end product is safe, potent, and free of chlorophyll.
- Ethanol. High grade grain alcohol can be used to create high quality cannabis oil appropriate for vape pen cartridges and other products. But this extraction method destroys the plant waxes, which may have health benefits that are favored by some product-makers.
- Olive oil. Extra virgin or otherwise, olive oil can also be used to extract cannabis oil. Dr. Arno Hazekamp, director of phytochemical research at Bedrocan BV, which supplies medical cannabis for the Dutch Health Ministry, reports this method is both safe and inexpensive, “You won’t blow yourself up making cannabis-infused olive oil.” However, cannabis-infused olive oil—whether CBD-rich or THC-dominant—is perishable and should be stored in a cool, dark place.
