Discovered by Gaoni and Mechoulam
in 1964, CBG or cannabigerol is one of the cannabinoids exclusively produced by the cannabis plant, which is stored in the trichome heads with the rest of cannabinoids and terpenes. While the CBG content in most plants is often low or very low – in most cases lower than 1% – this particular compound is crucial for cannabinoid synthesis
, as we have known for the past 4 decades ( (Shoyama, Yagi and Nishioka, Phytochemistry Journal, October 1975). As a general rule, hemp contains higher amounts of CBG
than commercial, narcotic cannabis strains.
CBG is a non-psychoactive phytocannabinoid
, which means it is produced by plants and does not “get you high”. It is believed that it has multiple medicinal properties which can be used to treat different conditions, and is also precursor – its acid form, to be exact – to the main cannabinoids (THCA, CBDA, CBCA) secreted in the trichome heads
, which in turn explains the low percentage of CBG found in mature plants when compared to their THC or CBD content.
