A Brief History of Cannabigerol

The history of cannabigerol, or CBG, is closely tied to the early days of cannabinoid research and the work of two pioneering Israeli chemists, Yehiel Gaoni and Raphael Mechoulam. In the 1960s, their investigations into the chemical makeup of the cannabis plant led to the identification and isolation of CBG—an important milestone that helped open the door to a deeper understanding of cannabinoids and their development.

CBG was later recognized as the precursor molecule from which other well-known cannabinoids, including THC and CBD, are synthesized during the plant’s growth. This unique role in the biosynthesis process has earned CBG the informal title “the mother of all cannabinoids.”

As scientific interest in cannabis expanded, researchers continued to explore the chemical pathways and biological roles of CBG. While much remains under investigation, CBG’s structural and functional position within the plant has made it a key point of reference in cannabinoid research.

The foundational work of Gaoni and Mechoulam remains central to how CBG is understood today. Their early contributions provided a basis for further study into the cannabis plant’s complex composition and the processes by which cannabinoids are formed.

cannabis leavesWhat Makes Cannabigerol (CBG) Distinct

Cannabigerol (CBG) stands out among the many naturally occurring cannabinoids in the cannabis plant due to its central role as a precursor to other well-known compounds, including THC and CBD. This section outlines what distinguishes CBG and explains how it is formed and extracted.

CBG originates from a compound known as cannabigerolic acid (CBGA), which appears in higher concentrations in younger cannabis plants. As the plant matures, CBGA is converted by natural enzymatic processes into other cannabinoid acids—specifically, THCA and CBDA—which eventually become THC and CBD when heated or processed.

Because most CBGA is converted into other cannabinoids during plant growth, only small amounts of CBG remain in mature plants, making its extraction more complex and often requiring selective breeding or harvesting at earlier stages.

CBG is non-psychoactive and does not produce intoxicating effects. From what I’ve observed, this has contributed to its appeal in both scientific and commercial contexts, particularly where there is interest in compounds that interact with the body’s natural systems without producing a “high.”

In recent years, high-CBG hemp strains have been developed to support ongoing research and further study of its distinct properties.

The Process of CBG Extraction

Extracting CBG typically involves isolating the compound from young cannabis plants, which contain higher levels of its acidic precursor, cannabigerolic acid (CBGA). As the plant matures, CBGA is largely converted into other cannabinoids, making early harvesting key to obtaining usable amounts of CBG.

One widely used method for refining CBG from plant material is chromatographic separation, a technique noted in research by Citti et al. and Wang et al. Other common methods include CO₂ extraction, which is valued for its ability to preserve cannabinoid integrity without leaving solvent residues.

Step Description
1. Harvesting Young cannabis plants with higher CBGA levels are selected to maximize CBG content.
2. Decarboxylation CBGA is converted into CBG through controlled heating, releasing carbon dioxide.
3. Extraction CBG is separated from the plant material using methods such as CO₂ extraction or chromatography.
4. Purification & Isolation Unwanted compounds are removed, and the extract is refined to isolate CBG.
5. Final Product The isolated CBG can then be used in a range of cannabinoid-based product formulations.

CBG Compared to Other Cannabinoids

When comparing cannabinoids, much attention is often given to the distinctions between CBG, CBD, and THC. While all three are derived from the cannabis plant, their chemical structures and interactions with the body’s natural systems distinguish them from one another.

This section outlines the key similarities and differences between these cannabinoids.

Cannabinoid Chemical Structure Psychoactive Properties Affinity for Cannabinoid Receptors Potential Clinical Applications
CBG (Cannabigerol) Unique precursor structure Non-psychoactive Low affinity for CB1 and CB2 receptors Studied for various biological interactions
CBD (Cannabidiol) Similar to CBG with molecular differences Non-psychoactive Low affinity for CB1 and CB2 receptors Studied for a range of physiological processes
THC (Tetrahydrocannabinol) Distinct from CBG and CBD Psychoactive High affinity for CB1 and moderate affinity for CB2 receptors Known for its psychoactive effects and studied for multiple applications

While THC is known for producing psychoactive effects, both CBG and CBD are non-psychoactive and do not cause intoxication. However, they differ in how they interact with cannabinoid receptors, which can influence their observed biological activity.

Research by Navarro et al. and Cascio et al. has demonstrated that CBG and CBD engage differently with these receptors, reflecting their unique characteristics within the broader cannabinoid profile.

"CBG and CBD are both non-psychoactive; however, they differ in their affinity for cannabinoid receptors."

In my experience following cannabinoid research, understanding these distinctions is important for advancing scientific discussions and supporting informed decision-making.

As research continues, recognising both the differences and commonalities among cannabinoids like CBG, CBD, and THC contributes to a more complete understanding of their roles in cannabis science.
