  • Patent number: 11207292
    Abstract: 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.

  • Patent number: 11147783
    Abstract: The present invention relates to the use of a therapeutically effective amount of cannabidiolic acid (CBDA) in the treatment of epilepsy. In one embodiment the CBDA is used in the treatment of generalised seizures, preferably tonic-clonic seizures. Preferably the CBDA used is in the form of a botanical drug substance in which the CBDA content is greater than 60%, and most preferably, it is a highly purified extract of cannabis such that the CBDA is present at greater than 95%, through 96% and 97% to most preferably, greater than 98% of the total extract (w/w) and the other components of the extract are characterised. In particular the cannabinoids tetrahydrocannabinol (THC) or tetrahydrocannabinol acid (THCA) have been substantially removed. Alternatively, the CBDA may be synthetically produced.

  • Publication number: 20210308072
    Abstract: The present invention relates to the use of a combination of two different cannabinoids in the treatment of leukaemia. The combination of CBD with THC appears to be particularly effective in reducing cell number in this disease. Preferably the cannabinoids are used in the form of an extract of cannabis such that many of the naturally occurring compounds are co-extracted with the THC or CBD. Alternatively, the cannabinoids are present in the form of a highly purified extract of cannabis, wherein the CBD or THC are present at greater than 98% of the total extract (w/w) and the other components of the extract are characterized. Alternatively, the CBD and THC may be synthetically produced. A specific ratio of CBD and THC such as 10:1 to 1:10 (CBD:THC) or more preferably between 2:1 to 1:2 (CBD:THC) may be used.

  • Publication number: 20210077455
    Abstract: The present invention relates to the use of cannabinoids in the treatment of a neurodegenerative disease or disorder. In particular the cannabinoids cannabidiolic acid (CBDA) and cannabidivarin (CBDV) were able to produce neuroprotective effects in a mouse model of neurodegenerative disease. In particular these effects were associated with the symptoms associated with amyotrophic lateral sclerosis (ALS). Furthermore, the combination of the cannabinoid tetrahydrocannabinol (THC) with the drug olexisome provided a synergistic disease modifying effect in a mouse model of neurodegenerative disease. In particular these effects were associated with the symptoms associated with ALS.
