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: CBD shows promise for improving the quality of life in people with Parkinson’s disease but larger trials are needed.
CBD has also been investigated for use in other forms of treatment-resistant epilepsy, usually in addition to conventional epilepsy medications. Results varied, but several trials showed CBD significantly reduced seizure frequency by almost 44% in most people. 3

Beneficial effects on anxiety after taking CBD were reported in an observational study where 21 patients out of 400 had anxiety. 8
Conclusion: CBD does not appear to interfere with sleep and may help people sleep better.
Other trials of 300 mg of CBD in people with anxiety or depression showed that CBD appeared to preserve sleep architecture, meaning it was unlikely to have any negative effects on sleep quality. 10
Nerve pain arises from damaged, irritated, or dysfunctional nerves. When confused and damaged, the nerve will send mixed signals to the brain as well as other bodily systems. Everyone reacts differently to pain.
Hence, CBD has an anti-inflammatory effect because when Cannabinoids engage with the Endocannabinoid system present in most organs throughout the body, inflammation is reduced systematically. Seeing as inflammation is involved in many diseases, the therapeutic potential of CBD is impressively wide-ranging.

CBD has neuroprotective properties that help reduce damage to the brain  as well as the nervous system and helps encourage the growth and development of new neurons. Traumatic blows, ischemia, or genetic and autoimmune disorder can result in permanent or temporary neural damage.
Hence, people already suffering from opioid addiction could benefit from CBD  because it will help them reduce cravings as well as opioid withdrawal symptoms.
CBD oil may reduce the risk of heart disease by alleviating hypertension (high blood pressure) in certain people, suggests a 2017 study in JCI Insight.
Clinical research has shown that CBD oil can trigger side effects. Severity and type can vary from one person to the next.
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.
Among the few human trials evaluating CBD’s anxiolytic effects was one published in the Brazilian Journal of Psychiatry in 2019. For this study, 57 men were given either CBD oil or a placebo before a public-speaking event. Anxiety was evaluated using physiological measures (such as blood pressure, heart rate, etc.) and a relatively reliable test for mood states known as the Visual Analog Mood Scale (VAMS).
Since some CBD oils contain trace amounts of THC, you should avoid driving or using heavy machinery when taking CBD oil, particularly when first starting treatment or using a new brand.
