By acting on the ECS, CBD may have many different effects on the body. Examples include: balancing the body’s overall physical functions (homeostasis), reducing pain sensation, and lessening the body’s reaction to injury or infection (inflammation).
Early research on CBD for the treatment of insomnia suggests that it may be effective. Additional studies are needed.
What Are the Medical Uses of CBD?
The National Academies of Sciences (NAS) found significant evidence that cannabis was an effective treatment for long-term (chronic) pain. However, much of the research was done outside of the U.S. And the forms of cannabis studied in the U.S. were not the same as those commonly used.
CBD may also increase the risk of side effects of certain medicines if used with them. Speak to your doctor or pharmacist before taking CBD with any other medication.
CBD should be used according to the manufacturer’s instructions. A person should read and follow the label carefully. Use no more than instructed. Using more may increase the chance of side effects or it may cause other problems.
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.
Ultimately, the primary reasons why people use CBD is because it tends to have calming, relaxing, pain-reducing effects. It has been used to alleviate joint pain and nerve pain, reduce anxiety and stress, treat insomnia, improve migraines, and address nausea.
She adds, “[Another difference is that] CBD is derived from hemp and has been classified as a legal substance. Hemp has <0.3% THC. Conversely, cannabis plants such as marijuana are grown to have much higher levels of THC and are still illegal according to the FDA, although individual states vary as to their use.”
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.
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 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.
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.
Here are a few tips to help you find the best CBD oil:
Remember, because CBD oils are largely unregulated, there is no guarantee that a product is either safe or effective.
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.
