CBG is a type of cannabinoid extracted from cannabis grass.
The main components of cannabis grass are CBD and THC, but CBG has the same precursors as these two main components.
The following is how CBG and CBD and THC change from their precursors.
In other words, CBG, THC, and CBD are produced by the decarboxylation of the same cannabin oleic acid, CBGa.
However, THCa/CBDa tends to convert to THC and CBD as the cannabis grass grows, whereas CBG tends to decrease gradually.
Therefore, it is only found in very small amounts in full and broad-spectrum CBD products as well.
The main reason why CBG is attracting attention is gaining attention is its therapeutic effect from a medical perspective without the psychoactive effects.

Effects you can expect from CBG | Remarks |
Antibacterial action | CBG, like CBD, is said to have antibacterial properties; a 2008 study published in the Journal of Natural Products suggested that it reacts to a type of staphylococcal infection and could be used as a therapeutic agent. |
Anti-inflammatory action | An animal study conducted in Biochemical Pharmacology in 2013 showed that CBG had an effective effect on inflammatory bowel disease in rats.It is also said to be effective in treating dermatitis, such as chronic dermatitis and psoriasis, and is being studied in medical institutions. |
Treatment Effectiveness of Glaucoma | Animal studies conducted in 1990 found that feeding samples with other cannabinoids, including CBG, was effective in lowering intraocular pressure and helping to treat glaucoma. |
Anticancer effects | CBG is said to have high antioxidant properties and has been shown to inhibit the formation and growth of cancer cells. |
Similar to CBD, CBG interacts with the body’s cannabinoid receptors CB1 and CB2 and has a variety of effects on the body by regulating the ECS properly.
It is also characterized as an agonist for functions other than the ECS.
CBG has been found to be responsive to the serotonin receptor 1A, which is called the happy hormone.
CBG has been put on the back burner because its content is lower in trace amounts than CBD and THC, and it is difficult to extract stably, so research has been put on the back burner.
However, with the recent focus on the entourage effect , research on CBG is also progressing.

It will be interesting to see the future parentage of CBG, which has been shown to act on more than just ECS.
