CBD hemp oil, such as that taken in CBD oil soft gels, fits better into the last category. Plenty of research has been done to establish that, although taken from a plant that is a member of the cannabis family, it has no psychoactive effects such as its relative marijuana.
In fact, numerous studies have been done to show that it actually can reverse some of the effects that THC has on the body, and may promote calmness.
In addition, CBD oil does not fit well into the pharmaceutical category as it does not require a prescription to purchase. Some doctors may recommend its use, but are unable to formally write a prescription for it. It is important to note that the FDA has approved one cannabidiol drug, known as Epidiolex, for use with patients with epilepsy.
CBD hemp oil, in general, however, is actually more akin to other superfoods such as berries, kale, or green tea. It is a concentrated extract of the hemp plant and is often diluted with oil and taken as CBD oil gel caps. CBD oil contains high amounts of essential fatty acids such as omega 3 and omega 6 which are both difficult to come by in the typical American diet.
