Everything you Need to Know about CBD Oil The use of CBD oils may be increasingly in vogue when it comes to everything from anxiety relief to anti-inflammatory healing, the use of cannabis in medicine is no new phenomenon. Cannabis is a plant-based or botanical product with a history dating back to the ancient world. The first convincing evidence that it was used as a medicine is from AD400 and in the US cannabis was extensively used as a medicine in the 19th and early 20th century. However, in 1937 federal restriction on both the use and sale of cannabis was put in place and its use in medicine came to an end around 1942. Fast forward half a decade and in 1996, California was the first state to legalise the use of botanical cannabis under physician supervision. As of 2019, more than 20 countries have legalised the use of medical cannabis and more than 30 states in the US alone. How does CBD oil work? In order to understand this, we first have to understand where these drugs work. Endocannabinoids (eCBs) and their receptors are found throughout the human body in places such as the nervous system, internal organs, connective tissues, glands and immune cells. The eCB system has a role better known as "eat, sleep, relax, forget and protect". There are two main components in cannabis- and cannabinoid-related products, the psychoactive component THC (tetrahydrocannabinol) and the non-psychoactive component CBD (cannabidiol). Due to CBD’s non-psychoactive effects, it has gained significant interest in the medical community and has shown a high potential for therapeutic use, including as an antiepileptic (treat epilepsy), anxiolytic (treat anxiety), antipsychotic (treat psychosis and mental health-related problems) and anti-inflammatory (treat pain and arthritis).
