Abstract:
1. A botanical drug substance (BDS) derived from cannabis plants having a tetrahydrocannabivarin (THCV) content of greater than 70% of total cannabinoids with delta 9 tetrahydrocannabinol (delta 9 THC) being reduced to a level of a minor constituent, which BDS has been obtained by extraction with carbon dioxide followed by a secondary extraction to remove a substantial proportion of non-cannabinoid materials including a substantial proportion of waxes, wax esters and glycerides, unsaturated fatty acid residues, terpenes, carotenes, and flavonoids, and in which the THCV content has been further enriched by separation or fractionation of cannabinoids other than THC, and wherein the delta 9 THC content is less than 2.0% of total cannabinoids.
