What is CBG?

Curious to learn more about cannabinoids like CBG? Let’s check out what CBG is.

Cannabis contains much more than the two most popular and well-known of the cannabinoids, CBD (cannabidiol) and THC (tetrahydrocannabinol), it also contains many other cannabinoids such as CBG (cannabigerol). While CBG may not be as well-known as the other cannabinoids, or present in the same quantities, it’s there, and it has an important role to play just like the other 113 cannabinoids found in the cannabis plant.

CBG is similar to CBD in that it won’t get you ‘high’ as THC does. It contains no psychoactive properties and won’t give you that high that you experience when you consume strains of cannabis with high levels of THC. CBG isn’t considered one of the major cannabinoids because it’s usually only found at very low levels, approximately 1%.

The interesting thing about CBG is that both CBD and THC start out as CBG. The cannabis plant produces cannabigerolic acid (CBGA), this is the precursor to three of the most important cannabinoid lines, THCA, CBDA, and CBCA. The enzymes within the cannabis plant turn the CBGA into either CBDA or THCA, which is then activated by light or heat to create CBD or THC. With most strains of marijuana, the CBGA is converted quickly into CBDA or THCA. When you get more THC, you end up with less CBD, or more CBD and less THC.

In an attempt to get trains of cannabis with higher amounts of CBG, growers, and breeders have been experimenting with cross-breeding of plants and genetic manipulation. There are also ways that more CBG can be recovered from cannabis plants of the plants are harvested in a certain time during the growing cycle. Growers need to pinpoint when the maximum amount of CBG is present, normally six weeks into the eight-week growing cycle.

The potential medical benefits of CBG

Within our bodies, the endocannabinoid system works hard to keep our body balanced in a state of homeostasis. The endocannabinoid helps control different areas of the body, with receptors spread throughout the brain, body, and central nervous system. CBG acts on the very specific areas within the physiological systems, and there has been a lot of promising research focused on this area.

CBG and Glaucoma 

There are receptors located within the eye structure. CBG is thought to be one of the best cannabinoids for treating glaucoma. The CBG works by decreasing the intraocular pressure in the eyes. CBG is also a very powerful vasodilator and has many neuroprotective benefits.

CBG and Inflammatory Bowel Disease 

During a recent study on mice, scientists discovered that CBG was effective in decreasing the inflammation characteristics of inflammatory bowel disease.

CBG and Huntington’s Disease 

During a study undertaken in 2015, researchers discovered that CBG protected neurons in mice that had Huntington’s disease. Huntington’s disease is characterized by nerve cell degeneration and damage in the brain.

CBG and Cancer 

CBG is also proving to have a lot of promise in the fight against cancers. CBG was shown to block the receptors which are responsible for cancer cell growth. In a study undertaken on mice, CBG inhibited the growth of colorectal cancer cells which are responsible for colon cancer growth.
