Properties of Cannabidiol

Cannabidiol (CBD) is a major active component of the Cannabis plant, which, unlike tetrahydrocannabinol (THC), is devoid of euphoria-inducing properties. During the last 10 years, there has been increasing interest in the use of CBD-enriched products for the treatment of epilepsy. In 2018, an oil-based highly purified liquid formulation of CBD (Epidiolex) derived from Cannabis sativa was approved by the US Food and Drug Administration for the treatment of seizures associated with Dravet syndrome (DS) and Lennox-Gastaut syndrome (LGS). The mechanisms underlying the antiseizure effects of CBD are unclear but may involve, among others, antagonism of G protein-coupled receptor 55 (GPR55), desensitization of transient receptor potential of vanilloid type 1 (TRPV1) channels, and inhibition of adenosine reuptake. CBD has complex and variable pharmacokinetics, with a prominent first-pass effect and a low oral bioavailability that increases fourfold when CBD is taken with a high-fat/high-calorie meal. https://www.ncbi.nlm.nih.gov/m/pubmed/31372958/?i=3&from=cbd%20oil
