With that being said, let’s discuss the wonderful thing we call CBD oil. CBD, cannabidiol, is one of over 85 active cannabinoids identified in hemp and other cannabis plants. CBD oil is derived from hemp, due to its abundance naturally occurring in the plant. CBD oil is extracted using the whole plant, stalks or flowers. Since hemp contains only trace amounts of THC, CBD oil products are non-intoxicating. 
Dr. Devinsky’s research, which was recently published in The New England Journal of Medicine, is beginning to provide that much-needed data in the field of epilepsy research. In a landmark multinational randomized double-blind study for a treatment-resistant form of the condition, subjects taking an oral solution of 20 mg CBD per kilogram of body weight for 14 weeks, along with standard treatment, experienced a 42 percent reduction in drop seizures (the muscles go limp). Those taking a 10 mg CBD per kilogram of body weight saw a 37 percent decrease; patients who got a placebo saw a 17.2 percent decrease. The mechanism hasn’t quite been worked out yet, Dr. Devinsky says, though there’s some evidence that a receptor known as GPR55 may be critical for the anti-seizure effect.

When looking at isolate, it is important to verify the purity. While many are in the 99.9+% range with no identifiable amounts of THC, there are lower purity ones (such as 99.5% or lower) that may still have trace amounts that show up on the labs. This small amount is typically negligible, and is nowhere near the amount usually found in full spectrum products. But it’s still something to be aware of for those seeking the purest they can find.
Dosage is important, because CBD can have side effects—the most common are tiredness, diarrhea, and changes in appetite and weight—so it’s best not to take more than you need. As CBD becomes more prevalent, says J. Michael Bostwick, M.D., a psychiatrist at Mayo Clinic in Rochester, MN, “I’m reasonably certain new kinds of side effects will emerge.”

Another major reason why CBD oil has been positively received in some parts of the medical community is its apparent effect on cancer and tumor growth.A study done by the researchers of the Institute of Toxicology and Pharmacology, University of Rostock, Germany recommends the use of CBD oil (even direct injection into tumors) to eliminate or reduce the size of the tumors. The antioxidants in CBD hemp oil also provide anti-mutagenic properties and lower users’ risk of cancer.


The appeal? Proponents claim CBD can help ease pain, anxiety, depression and stress, boost focus and productivity, improve the immune system, reduce inflammation and more. And – unlike its psychoactive cousin THC – CBD, they say, is harmless, legal and can't get you high. "The known is it's good for you, it helps a lot of people and a lot of things, and you can't hurt yourself," says Phil Asquith, a farmer and producer of extra-virgin olive oil in California, who founded one of the first companies in the CBD space. "The unknown is all the details."
Success stories like Oliver’s are everywhere, but there’s not a lot of data to back up those results. That’s because CBD comes from cannabis and, like nearly all other parts of the plant, is categorized by the Drug Enforcement Agency (DEA) as a Schedule 1 drug—the most restrictive classification. (Others on that list: heroin, Ecstasy, and peyote.) This classification, which cannabis advocates have tried for years to change, keeps cannabis-derived products, including CBD, from being properly studied in the U.S.

“What is CBD oil” may be your first question, but the real question we have to answer is, “What does CBD oil do?” CBD interacts with the body through the endogenous cannabinoid system (ECS) or endocannabinoid system. First discovered in the late 1980’s, the endocannabinoid system regulates the body’s homeostasis, or general state of balance, impacting such functions as mood, sleep, appetite, hormone regulation, and pain and immune response. Like an acrobat on a highwire, as the environment around us impacts our normal balance, the endocannabinoid system “corrects” by mediating our body’s reaction to keep us level.
