If you have been following the CBD industry, you have probably started hearing more about CBG — cannabigerol. It is showing up in tinctures, topicals, and vape cartridges, and for good reason. CBG is one of the most scientifically interesting cannabinoids in the hemp plant, and early research suggests it may offer benefits that CBD alone cannot deliver. Here is everything you need to know.
What Is CBG?
CBG, or cannabigerol, is a non-intoxicating cannabinoid found in the hemp plant. It is often called the “mother cannabinoid” because it is the chemical precursor from which most other cannabinoids — including CBD and THC — are synthesized. In young hemp plants, CBG is present in high concentrations. As the plant matures, enzymes convert most of the CBG into other cannabinoids, which is why mature hemp plants typically contain less than 1% CBG by weight.
This scarcity is one reason CBG products have historically been more expensive than CBD products. Producing a CBG-rich extract requires either harvesting hemp early (before full maturation) or selectively breeding high-CBG hemp strains — both of which require more resources and expertise than standard CBD extraction.
How Does CBG Work in the Body?
Like CBD, CBG interacts with the endocannabinoid system (ECS) — the network of receptors, enzymes, and endogenous cannabinoids that regulates mood, pain, inflammation, sleep, appetite, and immune function throughout the body. However, CBG interacts with the ECS differently than CBD:
- CB1 and CB2 receptor binding — Unlike CBD, which has low direct affinity for CB1 and CB2 receptors, CBG binds more directly to both receptor types. This may explain why CBG produces more immediate, noticeable effects for some users.
- Alpha-2 adrenoceptor agonism — CBG activates alpha-2 adrenoceptors, which are involved in regulating blood pressure, pain signaling, and the stress response.
- Serotonin receptor modulation — CBG has been shown to act as a 5-HT1A serotonin receptor antagonist, which may influence mood and anxiety.
- GABA reuptake inhibition — CBG inhibits the reuptake of GABA, an inhibitory neurotransmitter associated with relaxation and reduced anxiety. This mechanism is similar to how some anti-anxiety medications work.
What Are the Potential Benefits of CBG?
Research on CBG is still in early stages, but the existing science is promising across several areas:
Anti-Inflammatory Effects
CBG has demonstrated significant anti-inflammatory activity in preclinical studies, particularly in the gut. A 2013 study published in Biochemical Pharmacology found that CBG reduced inflammation in a mouse model of inflammatory bowel disease (IBD). This has made CBG a subject of interest for conditions like Crohn’s disease and ulcerative colitis.
Neuroprotective Properties
A 2015 study in Neurotherapeutics found that CBG was neuroprotective in a mouse model of Huntington’s disease, improving motor deficits and protecting neurons from degeneration. Researchers noted CBG’s potential as a treatment for neurodegenerative diseases.
Antibacterial Activity
A 2020 study published in ACS Infectious Diseases found that CBG was effective against methicillin-resistant Staphylococcus aureus (MRSA) — a dangerous antibiotic-resistant bacteria. CBG disrupted the bacterial cell membrane, suggesting potential as a novel antibacterial agent.
Appetite Stimulation
A 2016 study in Psychopharmacology found that CBG significantly increased food intake in rats without producing the intoxicating effects associated with THC. This suggests potential applications for conditions involving appetite loss or cachexia.
Glaucoma Support
Early research has shown that CBG may reduce intraocular pressure, which is the primary risk factor for glaucoma. CBG activates CB1 receptors in the eye, which are involved in regulating fluid drainage and pressure.
CBG vs. CBD — What’s the Difference?
| Property | CBG | CBD |
|---|---|---|
| Intoxicating? | No | No |
| Abundance in hemp | Low (<1%) | High (10–20%) |
| CB1/CB2 binding | Direct binding | Indirect modulation |
| Primary research focus | Inflammation, neuroprotection, antibacterial | Anxiety, epilepsy, pain, sleep |
| Effects onset | Often faster, more noticeable | Subtler, cumulative |
| Cost | Higher (scarce) | Lower (abundant) |
CBG and the Entourage Effect
One of the most compelling reasons to use CBG alongside CBD is the Entourage Effect — the scientifically recognized phenomenon where cannabinoids work synergistically to produce effects greater than any single compound alone. CBD and CBG appear to complement each other particularly well: CBD’s anxiolytic and analgesic properties combined with CBG’s anti-inflammatory and neuroprotective activity creates a broader therapeutic profile than either cannabinoid delivers independently.
This is why CBD Wellness formulates CBG-Rich Tinctures with a specific CBG-to-CBD ratio rather than simply adding trace amounts of CBG to a CBD base. The ratio matters. The synergy is intentional.
Who Should Consider CBG?
CBG may be particularly worth exploring if you are dealing with inflammatory conditions (gut, joints, skin), looking for mental clarity and focus without stimulants, interested in neuroprotective support, finding that CBD alone is not delivering the results you need, or wanting to maximize the Entourage Effect in your cannabinoid regimen.
