When people talk about cannabis, they usually focus on cannabinoids like THC and CBD, or maybe terpenes if they’re a bit more in the know. But there's a whole other side to the plant that deserves attention—flavonoids and phenols. These compounds don’t just influence aroma and taste; they play a crucial role in how cannabis interacts with our bodies. They might not be as famous as cannabinoids, but they’re key players in the entourage effect, the theory that cannabis compounds work better together than they do alone.

What Are Flavonoids?

Flavonoids are plant compounds that act as pigments, giving fruits, flowers, and leaves their color. In cannabis, they contribute to the shades of purple, red, and blue that some strains exhibit. But their role goes far beyond aesthetics. Flavonoids help protect the plant from UV rays, pests, and disease. More importantly, when consumed, they can affect how cannabis smells, tastes, and even how it makes you feel.

Did you know there are over 6,000 known flavonoids in nature? How about this - cannabis has its own special ones called cannaflavins! Some of the most common flavonoids in cannabis include:

• Quercetin – Found in apples and onions, this flavonoid has antioxidant properties.
• Kaempferol – Also found in kale and tea, it contributes to cannabis’s overall therapeutic effects.
• Cannaflavin A, B, and C – Unique to cannabis, these flavonoids are believed to play a role in modulating the effects of cannabinoids.

While flavonoids are present in many plants, the way they interact with cannabis compounds is what makes them stand out. Researchers believe that flavonoids may influence how cannabinoids are absorbed and processed by the body.

The Role of Phenols in Cannabis

Phenols are another class of compounds found in cannabis, and they’re known for their antioxidant and antimicrobial properties. Structurally, phenols are defined by their hydroxyl (-OH) groups attached to an aromatic benzene ring, which gives them unique chemical properties. They can be found in everyday foods like red wine, green tea, and dark chocolate.

In cannabis, phenolic compounds contribute to:

• Flavor and aroma – Many of the spicy, earthy, or woody notes in cannabis come from phenols.
• Preservation – Phenols help protect cannabinoids and terpenes from breaking down over time.
• Interaction with cannabinoids – Like flavonoids, phenols may influence the way cannabinoids work in the body, enhancing or moderating their effects.

The relationship between phenols and cannabinoids is still being studied, but the evidence suggests that they play a role in how cannabis affects different individuals.

The Entourage Effect: A Team Effort

The entourage effect is the idea that cannabis works best when all of its natural compounds—cannabinoids, terpenes, flavonoids, and phenols—work together. This concept was first explored by researchers Raphael Mechoulam and Shimon Ben-Shabat in 1998. Their studies suggested that even “inactive” cannabis compounds can enhance the effects of THC and CBD.

Dr. Ethan Russo, a leading cannabis researcher, expanded on this idea in 2011. He argued that terpenes and flavonoids could modify the way cannabinoids bind to receptors in the body, changing the overall experience of cannabis consumption. For example:

• Myrcene, a terpene, is thought to increase the permeability of cell membranes, allowing cannabinoids to take effect more quickly.
• Flavonoids like quercetin may influence how THC and CBD interact with receptors.
• Phenols might affect the bioavailability of cannabinoids, determining how much of the compound actually reaches the bloodstream.

While the entourage effect is still a topic of scientific debate, many cannabis users report noticeable differences in effects when consuming full-spectrum products versus isolates.

Full-Spectrum vs. Isolates: Why Flavonoids and Phenols Matter

If you’ve ever compared full-spectrum cannabis products to THC or CBD isolates, you might have noticed that the full-spectrum options feel more balanced and effective. That’s because they contain all the minor cannabinoids, terpenes, flavonoids, and phenols that contribute to the entourage effect.

• Isolates (pure THC or CBD) can be effective, but they lack the supporting cast of compounds that help modulate their effects.
• Full-spectrum extracts retain all the natural compounds of the cannabis plant, making for a more nuanced and potentially more effective experience.
• Broad-spectrum products contain most compounds except for THC, providing some entourage effect benefits without intoxication.

For therapeutic cannabis users, this distinction can be crucial. Some report needing higher doses of CBD isolates to achieve the same relief that a lower dose of full-spectrum CBD provides. This could be due to the way flavonoids and phenols enhance cannabinoid absorption.

The Science Still Has Questions

Despite the growing body of research on flavonoids, phenols, and the entourage effect, many unanswered questions remain. Some scientists argue that the entourage effect is overstated and primarily used as a marketing tool. Others believe there’s enough anecdotal and preliminary scientific evidence to support its legitimacy.

What we do know is that cannabis is more than just THC and CBD. The interaction between cannabinoids, terpenes, flavonoids, and phenols is incredibly complex, and we’re still learning how these compounds work together to shape the cannabis experience.

As cannabis research continues to evolve, flavonoids and phenols will likely gain more recognition for their role in shaping the effects of different strains. Understanding these compounds can help cannabis consumers make more informed choices about the products they use.

The More You Know…The Better Your High Will Be

For now, if you want to experience the full potential of the entourage effect, stick with full-spectrum products. And the next time you pick up a particularly aromatic or colorful strain, remember—it’s not just about the cannabinoids. The flavonoids and phenols are doing their part, too.
