Most studies investigating if CBD is beneficial at relieving nausea or vomiting, have used a combination of CBD and THC, rather than just CBD alone. A 2016 review found the combination to be either more effective or as effective as a placebo. 14
Conclusion: Topical CBD may help relieve inflammation and excessive sebum production associated with acne but more trials are needed.
Many other studies, both on animals and humans, have overwhelmingly concluded that CBD has immunosuppressive and anti-inflammatory properties which may make it a good choice for some autoimmune conditions or inflammation-related complaints. 16
8. Parkinson’s Disease
CBD (short for cannabidiol) is one of over 200 chemical compounds known as cannabinoids that are found in cannabis. 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
Conclusion: CBD shows promise for improving the quality of life in people with Parkinson’s disease but larger trials are needed.
In addition, more trials are needed to investigate its use for numerous other conditions, such as muscle-spasticity in multiple sclerosis, Alzheimer’s disease, substance-abuse treatment, and diabetes protection.
CBD can interact with other medications used for epilepsy and some serious side effects have been reported, notably, a decrease in liver function when given to people already taking valproate.

Cannabidiol and THC are just two of the plant’s more than 100 cannabinoids. THC is psychoactive, and CBD may or may not be, which is a matter of debate. THC can increase anxiety; it is not clear what effect CBD is having, if any, in reducing it. THC can lead to addiction and cravings; CBD is being studied to help those in recovery.
“If you take pure CBD, it’s pretty safe,” said Marcel Bonn-Miller, an adjunct assistant professor at the University of Pennsylvania’s Perelman School of Medicine. Side effects in the Epidiolex trial included diarrhea, sleepiness, fatigue, weakness, rash, decreased appetite and elevated liver enzymes. Also, the safe amount to consume in a day, or at all during pregnancy, is still not known.
Does CBD work?
Up in the wee hours of the night, stuck watching videos of puppies? CBD may be promising as a sleep aid; one of the side effects of the Epidiolex trials for epilepsy was drowsiness, according to Mr. MacKillop, a co-author of a review on cannabinoids and sleep. “If you are looking for new treatments for sleep, that may be a clue,” he said.
A recent chart review of 72 psychiatric patients treated with CBD found that anxiety improved, but not sleep. “Over all, we did not find that it panned out as a useful treatment for sleep,” said Dr. Scott Shannon, assistant clinical professor of psychiatry at the University of Colorado, Denver and the lead author of the review in The Permanente Journal.
More than 60 percent of CBD users were taking it for anxiety, according to a survey of 5,000 people. Does it help?
Cannabidiol, or CBD, is the lesser-known child of the cannabis sativa plant; its more famous sibling, tetrahydrocannabinol, or THC, is the active ingredient in pot that catapults users’ “high.” With roots in Central Asia, the plant is believed to have been first used medicinally — or for rituals — around 750 B.C., though there are other estimates too.
