The CBG a cannabinoid still little known but promising – Get Medical THC Store Quebec Canada

Herb Approach

Cannabigerol (CBG) is one of more than 150 cannabinoids identified in the cannabis plant. However, tetrahydrocannabinol (THC), cannabidiol (CBD) and cannabinol (CBN) are the most studied.

Cannabigerolic acid (CBGa) is derived from an olivetolic acid (a conjugated acid from an olivetolato). During the growth of the cannabis plant, the CBGa or CBG in acid form is converted into THCa, CBDa or CBCa, under the action of certain enzymes that metabolize and decompose the CBGa.

Later decarboxylation gives fruit to the phytocannabinoids THC, CBD and CBC, among others. However, the direct elimination of a carboxyl group in the CBGa forms the CBG in the plant, approximately 1%.

How does the CBG work?

An article published in the British Jounal of Pharmacology[1] suggests that it acts as a potent agonist (activator) of the alpha-2 adrenergic receptor, and antagonist (blocker) of the 5-HT1A receptor.

In addition, it interacts with the CB1 receptor as a competitive antagonist (blocker that competes for activator binding sites), mainly affecting the central nervous system. Also, it has significant affinity for CB2 receptors. However, the researchers have not yet concluded whether their function in these receptors is agonist or antagonist.

Therapeutic effects of CBG

A study published in 2009 on glaucoma[2] in animals showed that both THC and CBG could reduce intraocular pressure. It should also be borne in mind that cannabigerol is a non-psychoactive substance.

Another scientific article argues that CBG may decrease the progression of colorectal cancer[3], by selectively inhibiting the growth of tumor cells, blocking transient potential channels (TRPs), which are involved in the growth of tumor cells.

Old publications support its analgesic, antibacterial, anti-inflammatory, antidepressant and antihypertensive effect. Another interesting aspect of cannabigerol is that at high doses it proved to have the property of being cytotoxic in carcinoma of epithelial cells and breast cancer, as well as being a good inhibitor in the proliferation of keratocinocytes, potentially therapeutic in psoriasis. At the experimental level, the CBG could positively help the treatment of intestinal inflammatory diseases[4].

Finally, a study in 2015[5] with mice explains that CBG has a promising neuroprotective effect for the treatment of Huntington's disease. Other diseases such as Parkinson's[6] or multiple sclerosis[7] They could also benefit from this property. In spite of the above, it is necessary to carry out studies in humans to clarify the side effects, the necessary doses, or even the result with a combination of phytocannabinoids.

What future does the CBG have?

Being a non-psychoactive substance opens the way for medical research. Unfortunately, due to its low concentration in the cannabis plant, the CBG is difficult to produce in large quantities. This aspect makes it less attractive than CBD, whose concentration is very high.

Even so, better cultivation methods are being studied to increase the amount of cannabigerol in the plant, since it has been discovered that harvesting the cannabis plant after six weeks of flowering, instead of eight weeks, allows a better concentration of cannabis to be obtained. CBG
