CBD oil or cannabidiol oil is a substance derived from the hemp or cannabis plant containing high amounts of the cannabinoid cannabidiol.
Most CBD oil comes from industrial hemp rather than psychoactive marijuana strains; while the two plants are related, industrial hemp does not contain nearly as much psychoactive tetrahydrocannabiol, another cannabinoid better known as THC. In fact, according to the 2014 Farm Bill, industrial hemp cannot contain more than .3 percent THC on a dry weight basis – a nearly negligible amount.
To answer this, we need to take a step back to address the endocannabinoid system, a system within the body whose receptors (CB1 and CB2) have an enormous impact on our health and well-being.
"CB1 receptors in the brain are associated with emotions, mood, appetite, coordination, movement, and pain," explains Stormy Simon, the former president of Overstock.com who recently left the corporate world to become an advocate for cannabis. "CB2 receptors are found in the immune system and throughout tissues of the spleen and tonsils."
The endocannabinoid system is a relatively new discovery. In fact, Simon notes, it was actually discovered and named after the cannabinoids in the cannabis plant. Seeing as cannabinoids are the compounds that activate this system, many have posited that cannabinoids like THC or CBD could help improve endocannabinoid function.
Before adding CBD oil to your regimen, as with any supplement, be sure to check with your doctor to make sure that it's a good choice for you. This is especially true if you are taking certain anti-seizure medications.
CBD oil can be consumed in a myriad of ways: tinctures, oil vaping, capsules, sublinguals, or even topicals. When taking CBD, always follow the instructions on the package of the product you have purchased.
The same growing techniques apply to CBD-rich cannabis and high-THC cannabis. Much like growing high-THC strains, harvesting earlier or later can impact the cannabinoid levels as well as the terpenoid profile of the plant. For somewhat higher CBD content, try harvesting CBD plants a couple weeks earlier than one would typically harvest a high THC strain.
