In June 2018, the U.S. Food and Drug Administration (FDA) approved Epidiolex, a CBD oral solution used for the treatment of certain rare forms of epilepsy in children under 2—Dravet syndrome and Lennox-Gastaut syndrome.

Scientists believe that CBD reduces nerve pain by binding to glycine receptors in the brain that regulate the speed at which nerve signals pass between nerve cells.
As CBD grows in popularity, so does the research on it but there are currently few clinical studies on the effects of CBD oil. As such, some of these claims are better supported by studies than others.
In all but a few studies, lower doses of CBD (10 milligrams per kilogram, mg/kg, or less) improved some symptoms of anxiety. Higher doses (100 mg/kg or more) exhibited virtually no effect.
There is currently no known “correct” dose of CBD oil. Depending on individual needs and what is being treated, the daily dose may range between 5 and 25 mg.
To avoid interactions, tell your doctor and pharmacist about all prescription, over-the-counter, herbal, or recreational drugs you are taking.
If you are thinking about using CBD oil to treat a health condition, be sure to speak with your healthcare provider to ensure that it is the right option for you.

Animal studies have shown that CBD has a positive effect on serotonin levels in the brain, and serotonin. Low levels of serotonin are thought to play a key role in mood as well as pain. 11

It is the second most prevalent active compound found in cannabis, behind THC (tetrahydrocannabinol), which is the compound in cannabis that has psychoactive properties and gives people a high. 2
A laboratory study found that CBD prevented human sebocytes from creating too much sebum in addition to having an anti-inflammatory effect, preventing inflammatory cytokines from activating. Because excessive sebum and inflammation are characteristic of acne, topical CBD could be an effective treatment for acne and may prevent or reduce future breakouts. 12,13
Conclusion: CBD shows promise for improving the quality of life in people with Parkinson’s disease but larger trials are needed.
