Medical models of cannabis can be divided into two basic types. Those with the predominance of cannabis indica, which have rather sedative, soothing effects. The second less used species is cannabis sativa, which has rather stimulating effects and is used more for psychiatric disease. In some species, a substance called CBD, one of 60 cannabis in cannabis, appears in greater quantities.

New to the last let are high C speciesBD-toanabidiol.

CBD is produced by THC conversion and has stronger effects for medical use. It is these species that are the best of medical marijuana models. CBD is more prominent than THC, especially against pain, epilepsy, schizophrenia, stomach pain, cancer.

CBD sin most cannabis species represented by up to 1% (at THC from 10 to 20%). For specially bred species, mostly with the "CBD" in the name, we can usually find a cannabidiol content of around 5%, and a similar THC value that the CBD dampens. 

CBD can also be increased in conventional models when cannabis matures. The older a cannabis, the more THC changes, which is also known to make the marijuana coating darker. In the laboratory, the species with almost the opposite content, CBD 15% and THC 1%, was grown.

Kanabid Iol is a powerful antioxidant.

Unlike THC, CBD does not have a unified legal legality, it is not illegal as THC in all countries. Unfortunately, the CBD-only plant has not been bred.
