Dubbed the “mother of all cannabinoids,” CBG is the chemical precursor from which other cannabinoids are synthesized, making it a foundational element in the cannabis plant.

 

Origins and Chemistry

CBG is initially present in the cannabis plant as cannabigerolic acid (CBGA). During the plant’s growth, CBGA breaks down and transforms into the acidic forms of THC, CBD, and CBC (cannabichromene). Because of this conversion process, mature cannabis plants typically contain only trace amounts of CBG—usually less than 1%. This scarcity has made CBG research challenging, but advancements in cultivation techniques are beginning to yield higher CBG concentrations, spurring renewed scientific interest.

 

Therapeutic Potential

Preliminary research suggests that CBG holds promise in several therapeutic areas, distinct from those of THC and CBD. Here are some of its potential benefits.

​

Anti-Inflammatory and Analgesic

CBG has shown significant anti-inflammatory properties, making it a potential treatment for conditions like inflammatory bowel disease (IBD). Studies on mice have indicated that CBG can reduce inflammation and oxidative stress, offering hope for human applications in managing chronic inflammatory conditions.

 

Neuroprotective Effects

CBG’s neuroprotective properties are another area of interest. Research indicates that CBG may help protect neurons and support neurogenesis, the growth of new brain cells. This could be particularly beneficial in treating neurodegenerative diseases such as Huntington’s and Parkinson’s.

 

Antibacterial Properties

CBG has demonstrated potent antibacterial effects, especially against antibiotic-resistant strains of bacteria like MRSA (methicillin-resistant Staphylococcus aureus). This positions CBG as a potential candidate in the fight against antibiotic-resistant infections.

 

Glaucoma Relief

CBG’s ability to reduce intraocular pressure makes it a promising treatment for glaucoma. This cannabinoid’s vasodilatory and neuroprotective effects could help protect the eye and preserve vision.

 

The Entourage Effect with CBG

Like CBD and THC, CBG also participates in the entourage effect, where multiple cannabinoids and terpenes work together to enhance therapeutic benefits. CBG’s role in this synergy is multifaceted:

Amplifying Benefits: CBG can enhance the anti-inflammatory and analgesic properties of other cannabinoids.

Balancing Psychoactivity: While not psychoactive itself, CBG can modulate the effects of THC, potentially reducing paranoia and anxiety, similar to CBD.

 

The Science

Let’s dive into the science of how CBG, or cannabigerol, interacts with the endocannabinoid system (ECS).

The endocannabinoid system is a complex network of receptors, endogenous cannabinoids (endocannabinoids), and enzymes that play a crucial role in maintaining homeostasis in the body. The two primary receptors in the ECS are CB1 and CB2. CB1 receptors are predominantly found in the central nervous system, while CB2 receptors are mainly located in the immune system and peripheral tissues.

CBG interacts with the ECS in several ways:

 

CB1 and CB2 receptor interaction: CBG has been shown to have a low affinity for both CB1 and CB2 receptors, meaning it does not bind strongly to these receptors like THC does.

However, it still influences the ECS by modulating the activity of these receptors. CBG acts as a partial agonist at CB1 receptors, potentially reducing the psychoactive effects of THC. It also acts as an antagonist at CB2 receptors, which may contribute to its anti-inflammatory properties.

 

TRPV1 and TRPA1 receptor interaction: CBG has been found to interact with other receptors in the body, such as TRPV1 and TRPA1, which are involved in pain perception, inflammation, and temperature regulation. By activating these receptors, CBG may help reduce pain and inflammation in the body.

​

Anandamide reuptake inhibition: CBG has been shown to inhibit the reuptake of anandamide, one of the primary endocannabinoids produced by the body. By preventing the reuptake of anandamide, CBG can increase its levels in the body, potentially leading to enhanced mood, reduced anxiety, and other beneficial effects.

 

GABA reuptake inhibition: CBG has also been found to inhibit the reuptake of gamma-aminobutyric acid (GABA), a neurotransmitter that plays a role in regulating anxiety, stress, and muscle tension. By increasing GABA levels in the brain, CBG may promote relaxation and reduce anxiety.

 

Neuroprotective and anti-inflammatory properties: CBG has demonstrated neuroprotective and anti-inflammatory properties, which may be mediated through its interaction with the ECS. By reducing inflammation in the brain and protecting neurons from damage, CBG may have potential therapeutic applications in treating neurodegenerative diseases such as Alzheimer’s and Parkinson’s.

 

The Entourage Effect

Like other cannabinoids, CBG is believed to contribute to the entourage effect, whereby the combined action of multiple cannabinoids and terpenes in the cannabis plant produces a more significant therapeutic effect than any single compound alone. CBG may work synergistically with other cannabinoids to enhance their beneficial properties.

 

It’s important to note that while the science behind CBG is promising, more research is needed to fully understand its mechanisms of action and potential therapeutic applications. As the cannabis industry continues to grow and evolve, we can expect to see more studies exploring the unique properties and benefits of CBG and other minor cannabinoids.
