Patent number: 11207292Abstract: Cannabidiol (CBD) is a cannabinoid designated chemically as 2-[(1R,6R)-3-Methyl-6-(1-methylethenyl)-2-cyclohexen-1-yl]-5-pentyl-1,3-benzenediol. Its empirical formula is C21H30O2 and its molecular weight is 314.46. CBD is a cannabinoid that naturally occurs in the Cannabis sativa L. plant. CBD is a white to pale yellow crystalline solid which is insoluble in water and soluble in organic solvents. The present invention encompasses the surprising recognition that certain CBD preparations which are prepared from a botanical origin are more effective in treating diseases or disorders than preparations of CBD which are synthetic or purified to the extent no other impurities in the form of other cannabinoids are present. Prior CBD compositions have been prepared such that no psychoactive components, e.g., tetrahydrocannabinol (THC), remain in the final CBD preparation. Surprisingly, the absence of such minor impurities reduces the efficacy of CBD treatment.Type: GrantFiled: September 3, 2020Date of Patent: December 28, 2021Assignee: GW Research LimitedInventors: Geoffrey Guy, Volker Knappertz, Benjamin Whalley, Marie Woolley-Roberts, James Brodie, Katarzyna Lach-Falcone, Alan Sutton, Royston Gray, Rohini Rajyalaxmi Rana
