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.
Remember, because CBD oils are largely unregulated, there is no guarantee that a product is either safe or effective.
This cannabis extract may help treat nerve pain, anxiety, and epilepsy
Many of these interactions are mild and require no adjustment to treatment. Others may require a drug substitution or the separation of doses by several hours.
CBD oil should be avoided during pregnancy and breastfeeding. A 2018 study from the American Academy of Pediatrics warned women to avoid marijuana during pregnancy due to the potential risks to a baby’s development. Although it is unclear how CBD contributes, CBD is known to pass through the placental barrier.
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 is said that CBD may provide some benefits for those who have neurological disorders, such as multiple sclerosis and epilepsy. Studies have found that cannabis oil can reduce spasms in up to 75% of multiple sclerosis sufferers. Another study gave people with epilepsy CBD oil after which their seizures reduced by 36.5%.
Many people who live with anxiety and depression have become interested in cannabis oil’s natural approach as it has shown to treat these disorders without the side effects experienced when using other conventional drugs. It has been shown that CBD reduces anxiety, speech performance and cognitive impairment. This is because CBD is believed to act on the receptors of the brain for serotonin (the neurotransmitter that regulates social behavior and mood).
In plain terms, this means that cannabis and THC products may have to be combined together to help the body relax. By relaxing the body and mind, and inducing a lower energy level, it will be easier to get your heart rate down and clear your head before a long night of peaceful sleep.
For people who suffer from insomnia, constant anxiety during the night or simply struggle to get a sound, restful night of undisturbed sleep, cannabis sativa essential oil may work like a charm. However, according to a research report published by Dr. Ethan Russo, Director of Research for the International Cannabis and Cannabinoids Institute, t erpenoids produce an “entourage effect”. 
CBD oil is made by mixing the extracted CBD or cannabidiol from the cannabis or marijuana plant (Cannabis Sativa) with coconut or hemp seed oil. CBD oil possesses cannabidiol; while THC is psychoactive, CBD is not, thereby helping relieve pain and depression, fighting cancer, and reducing anxiety. It also improves the quality of sleep, boosts appetite, and optimizes digestion.
Promotes Heart Health
In a statement released in June of 2018 by FDA, it states, “the FDA approved a purified form of the drug cannabidiol (CBD). The new product was approved to treat seizures associated with two rare, severe forms of epilepsy in patients two years of age and older”. 
CBD oil has become very popular and famous in the recent years due to the movement for legalized marijuana in certain countries.
In terms of eye health, cannabis and cannabis essential oil have been linked to a reduction in glaucoma and prevention of macular degeneration, according to a report published by Dr. John Merritt, Department of Ophthalmology School of Medicine, University of North Carolina. Eye health is one of the major reasons why people turn to cannabis essential oil as they age. 
Although there is some controversy over this and with a great deal of research still ongoing, early reports have shown that the active ingredients in cannabis essential oil can have preventive effects on cancer. It can also cause a reduction in tumor size, thereby making it easier to effectively fight cancer (more research required on this).
