The cannabis plant contains many phyto-cannabinoids including the two most abundant, cannabidiol (CBD) and delta-9-tetrahydrocannbinol (THC). There are distinguishable differences in their effects, but when combined they have the potential to enhance the plant’s therapeutic benefits. CBD is also believed to balance out many undesired psychoactive activities of THC.

For different conditions, the ratio of the respective phyto-cannabinoids in the CBMP required to achieve a pharmacologic effect may differ drastically, and therefore clinical research exploring this has been slow to emerge.
