Cannabis extracts and methods of preparing and using same
The invention relates to the extraction of pharmaceutically active components from plant materials, and more particularly to the preparation of a botanical drug substance (BDS) for incorporation in to a medicament. It also relates to a BDS, for use in pharmaceutical formulations. In particular it relates to BDS comprising cannabinoids obtained by extraction from cannabis.

b. a formulation wherein at least 95% of the total cannabinoids in the formulation is tetrahydrocannabinol (THC);
c. a formulation wherein at least 95% of the total cannabinoids in the formulation is cannabidiol (CBD);
d. a formulation wherein at least 95% of the total cannabinoids in the formulation are THCa and cannabidiolic acid (CBDa);
e. a formulation wherein at least 95% of the total cannabinoids in the formulation are THC and CBD;
f. a formulation wherein at least 95% of the total cannabinoids in the formulation are CBD, cannabinol (CBN) and THC;
g. a formulation wherein at least 95% of the total cannabinoids in the formulation is cannabidiol (CBDa);
h. a formulation wherein at least 95% of the total cannabinoids in the formulation is cannabichromene (CBC);

j. a formulation comprising at least 95% tetrahydrocannabinol (THC) as the only cannabinoid in the formulation; and
k. a formulation wherein at least 95% of the total cannabinoids in the formulation is tetrahydrocannabinol (THC) from cannabis indica or cannabis ruderalis.
2. The method of claim 1 , wherein the cannabinoid formulation further comprises least one terpene and/or flavonoid.
3. The method of claim 2 , wherein the cannabinoid formulation comprises no more than 4% terpene.
4. The method of claim 1 , wherein at least 95% of the total cannabinoids in the formulation is cannabidiol (CBD) and the formulation comprises less than 1% THC.
5. The method of claim 1 , wherein at least 95% of the total cannabinoids in the formulation are CBD, cannabinol (CBN) and THC, wherein the formulation comprises less than 9% THC.
6. The method of claim 1 , wherein at least 95% of the total cannabinoids in the formulation is tetrahydrocannabinolic acid (THCa), and the formulation comprises no more that 4% terpene.
7. The method of claim 1 , wherein at least 95% of the total cannabinoids in the formulation is tetrahydrocannabinol.
8. The method of claim 6 or 7 , wherein the terpene in the formulation comprises a mixture of myrcene, caryophyllene, and limonene.
9. The method of claim 1 , wherein at least 95% of the total cannabinoids in the formulation is cannabidiol (CBD), and the formulation comprises no more than 4% terpene.
10. The method of claim 9 , wherein the terpene in the formulation comprises a mixture of myrcene, caryophyllene, and limonene.
11. The method of claim 1 , wherein at least 95% of the total cannabinoids in the formulation are THCa and cannabidiolic acid (CBDa) and the formulation comprises no more than 4% terpene.
12. The method of claim 1 , wherein at least 95% of the total cannabinoids in the formulation are THC and CBD and the formulation comprises no more than 4% terpene.
13. The method of claim 11 or 12 , wherein the terpene in the formulation comprises a mixture of limonene, pinene, and caryophyllene.
14. The method of claim 11 or 12 , wherein the terpene in the formulation comprises a mixture of myrcene, limonene, pinene, and caryophyllene.
15. The method of claim 1 , wherein at least 95% of the total cannabinoids in the formulation are CBD, cannabinol (CBN) and THC and the formulation comprises no more than 4% terpene.
16. The method of claim 15 , wherein the terpene in the formulation comprises a mixture of myrcene, pinene and caryophyllene.
17. The method of claim 1 , wherein the cannabinoid formulation is infused in a medium chain triglyceride.
18. The method of claim 1 , wherein the pH of the cannabinoid formulation is at least pH 8.0.
19. The method of claim 1 , wherein the formulation is administered in the morning; the afternoon; evening and at bedtime.
