CBG (Cannabidiol)

What is CBG (a.k.a.Cannabidiol)

Cannabigerol (CBG) is one of the naturally occurring cannabinoids found in cannabis plants. CBD is typically the third to fifth most abundant Cannabinoid in most medical and recreational cannabis strains, and the most abundant cannabinoid in some specially selected hemp cultivars.

How is CBG Made from Hemp or Cannabis?

CBD is commonly extracted from the specially bred high CBG hemp cultivars.

CBG is found on the cannabis and hemp flowers (buds) and leaves of cannabis plants. It is showing great promise as a therapeutic compound for a range of conditions, but research is in it's infancy.

CBG Extraction from hemp

CBG is processed and extracted from hemp in the same way that CBD and THC are.

First harvested hemp is tested, dried and milled ready for extraction (read more at Hemp Post harvesting processing) and then the CBG and other cannabinoids is extracted from hemp using a solvent such as CO2, Ethanol to produce a hemp oil.

If CBD rich plants are used, this hemp oil will be CBD oil. If CBG rich plants are used this would be a CBG oil.

CBG oil can be further refined to CBG distillate or isolate.

Currently most hemp cultivars commonly have low levels of hemp. New cultivars are being farmed which are Type IV cannabis and lack the CBD and THC synthase genes so only produce CBG.

These will be an important and dominant source of CBG.

CBG Extracts

CBG Extracts include CBG oil, CBG distillate and CBG isolate.

CBG Oil

CBG Oil is hemp oil extracted from hemp, or a refined version thereof, which is rich in CBG.

CBG oil is typically 15 to 50% CBG

CBG Distillate

CBG Distillate is distilled hemp oil rich in CBG.

CBG distillate is typically 45 to 70% CBG

CBG Isolate

CBG Isolate is purified CBG containing 95% to 99% CBG. CBG is rarer, more expensive and more difficult to crystallise than CBD so the purity generally isn't as high as routinely seen for CBD isolate.
