Most people are familiar with CBD and THC, but another cannabinoid is starting to receive more attention in research and wellness conversations: CBG.
Often referred to as the “mother cannabinoid,” CBG plays an important role in how many other cannabinoids are formed in the cannabis and hemp plants. While research on CBG is still emerging, scientists are studying how it interacts with the body’s endocannabinoid system (ECS) and other biological pathways.
This article explores what CBG is, how it works, and why researchers and wellness professionals are paying closer attention to it.
CBG stands for cannabigerol, a naturally occurring cannabinoid found in cannabis and hemp plants.
In young cannabis plants, cannabinoids begin as CBGA (cannabigerolic acid). As the plant matures, enzymes convert CBGA into the acidic forms of other cannabinoids, including:
THCA → which becomes THC
CBDA → which becomes CBD
CBCA → which becomes CBC
Because CBGA is the precursor to these compounds, CBG is often called the “parent” or “mother” cannabinoid.

CBG typically appears in much smaller concentrations in mature hemp plants than CBD.
By the time a plant reaches harvest, much of the original CBGA has already been converted into other cannabinoids. As a result, most plants contain less than 1% CBG.
Because of this, producing CBG products often requires:
Special hemp cultivars bred for higher CBG content
Earlier harvesting times
More intensive extraction processes
These factors are part of the reason CBG products are often less common—and sometimes more expensive—than CBD products.
Like other cannabinoids, CBG interacts with the body’s endocannabinoid system (ECS).
The ECS is a regulatory network found throughout the body that helps maintain balance across many systems, including:
Immune signaling
Nervous system activity
Stress response
Sleep cycles
Appetite and metabolism
The ECS includes cannabinoid receptors known as CB1 and CB2, along with endocannabinoids produced naturally by the body.
Research suggests CBG may interact with these receptors differently than CBD.
A review published in Frontiers in Pharmacology explains that CBG can act as a partial agonist at CB1 and CB2 receptors, while also interacting with several other receptor systems involved in inflammation and neurological signaling.

While research on CBG is still relatively early compared with CBD, scientists are exploring several areas where it may play a role in the body.
Some preclinical studies are examining how CBG interacts with neurological pathways.
For example, a study published in Neurotherapeutics investigated cannabinoids—including CBG—in neurological disease models and found potential interactions with pathways related to neuroprotection and inflammation.

Researchers are also studying how cannabinoids like CBG interact with inflammatory signaling pathways.
A review published in Molecules discusses how cannabinoids can influence immune responses and inflammatory mediators through various receptor systems.

Some early animal studies have explored how CBG may influence appetite signaling and metabolic pathways.
A study published in Psychopharmacology found that CBG stimulated appetite in animal models without the intoxicating effects associated with THC.

While findings like these are interesting, researchers consistently emphasize that more human studies are needed to fully understand how CBG may affect health outcomes.
Both CBD and CBG are non-intoxicating cannabinoids, meaning they do not produce the “high” associated with THC.
However, they differ in several ways:
| CBD | CBG |
|---|---|
| More widely researched | Research still emerging |
| Often interacts indirectly with ECS receptors | May interact more directly with CB1 and CB2 receptors |
| More abundant in hemp plants | Typically present in very small amounts |
Many formulations include multiple cannabinoids together, which researchers sometimes refer to as the “entourage effect,” a concept suggesting cannabinoids and plant compounds may work together through complementary pathways.
A review published in Frontiers in Plant Science discusses this concept in more detail:
https://www.frontiersin.org/articles/10.3389/fpls.2018.01969/full
Because cannabinoids interact with multiple receptor systems, some formulations combine compounds like CBD and CBG along with terpenes.
Researchers are exploring whether combinations of plant compounds may influence:
Absorption
Biological signaling pathways
Nervous system regulation
However, more research is needed to fully understand how these combinations influence health outcomes.
As cannabinoids like CBG become more widely available, product quality and formulation transparency become increasingly important.
When evaluating cannabinoid products, experts often recommend looking for:
Third-party lab testing
Certificates of analysis (COAs)
Clear cannabinoid content labeling
Transparent sourcing and manufacturing
Understanding the cannabinoid profile and formulation can help consumers make more informed decisions.
Because cannabinoids interact with complex biological systems, individualized guidance can be helpful when exploring different formulations or wellness approaches.
At Hempeutics, we focus on a pharmacist-led approach to cannabinoid education, helping people better understand how different cannabinoids, formulations, and dosing strategies may fit into their personal wellness goals.

CBG is one of the many cannabinoids found in cannabis and hemp plants, and researchers are increasingly interested in how it interacts with the body’s endocannabinoid system and other signaling pathways.
Although research is still evolving, early studies suggest that CBG may play unique roles in neurological signaling, inflammation pathways, and metabolic processes.
As cannabinoid science continues to develop, understanding compounds like CBG can help consumers make more informed choices about cannabinoid-based wellness products.
