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.
CBD oil is an extract of Cannabis indica or Cannabis sativa—the same plants that, when dried, make marijuana. CBD oil is believed by some to treat pain, reduce anxiety, and stimulate appetite in the same way that marijuana does, but without its psychoactive effects. CBD has also shown promise in treating certain types of seizures.
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.
CBD is the short name for cannabidiol, one of the two chemicals—among the dozens in cannabis—that have the most health benefits. The other, tetrahydrocannabinol (THC), produces the psychoactive effects described as being “high.” CBD oil generally does not contain THC, although some trace amounts may be present in products sold in certain states.

It’s important to point out that CBD is not regulated by the FDA and therefore dosages might not be accurate. It’s also difficult to know what an appropriate dose is the first time you try a new product.
In some cases, those who ingest CBD supplements might experience nausea, says Dr. Matharu-Daley. This depends on how sensitive the person is to CBD, as well as the amount they ingest.
CBD is one of the many chemical compounds that is found in the cannabis plant—referred to as cannabis sativa. There are two primary parts of the plant that humans use. One is THC, or Delta-9-Tetrahydrocannabinol, and the other is CBD. Though they’re from the same plant, THC and CBD are quite different from each other.
Are There Any Benefits Associated With Using CBD?
“If the CBD is from a reputable source and one that has been inspected by a third-party independent lab, the content of CBD is more reliable,” notes Dr. Matharu-Daley. “The CBD should be organically grown, free of pesticides and heavy metals, and not sourced in food which can affect absorption. Generally, CBD is safe and side effects are few at low doses.”
CBD might interfere with the other medications you take. Dr. Matharu-Daley says it’s important to talk to your doctor about whether CBD could affect your existing prescriptions.
Some people may get diarrhea or liver problems [when using CBD]. This is dependent on the individual and their medical history, so monitoring is important,” says Dr. Matharu-Daley.
CBD is technically an unregulated substance in the United States and therefore it ought to be used with caution. This is especially important for those taking additional medications and/or those with ongoing medical issues. That said, preliminary research on CBD and its benefits are promising in relation to helping with mild to moderate health concerns and it is generally considered a safe substance. Health professionals do not consider CBD a cure-all for serious medical issues, including cancer.
