CBD oil contains CBD mixed with an inert carrier oil, such as coconut oil or hemp seed oil. The bottled oil, called a tincture, is sold in various concentrations. There are also CBD capsules, CBD gummies, and under-the-tongue CBD sprays.
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.
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. Both are exceptionally rare genetic disorders causing lifelong catastrophic seizures that begin during the first year of life.
CBD oil may also increase liver enzymes (a marker of liver inflammation). People with liver disease should use CBD oil with caution, ideally under the care of a doctor who can regularly check blood liver enzyme levels.
There have also been suggestions that CBD may aid in the treatment of cannabis and nicotine addiction. Further research is needed.
That said, CBD isolate is still a useful option for people who must refrain from having any THC in their system, or for those who do not need a full-spectrum CBD product.
While CBD isolate may provide pain relief, research indicates that a full-spectrum CBD product may be even more effective because cannabidiol acts synergistically with THC to boost its analgesic effects.
Pain and inflammation relief
Another 2019 study suggests that CBD significantly decreased anxiety in teenagers with social anxiety.
CBD isolate is a good option for those who would like to try CBD, but who cannot or do not want to ingest any tetrahydrocannabinol (THC), which is the active ingredient in cannabis. Most other CBD products contain at least a small percentage of THC.
A 2019 study , for example, explored whether CBD improves sleep or anxiety, or both. The researchers reviewed the charts of 72 adults who had anxiety or sleeping problems at a psychiatric clinic.
