What Is Caryophyllene? The Peppery Terpene That Acts Like a Cannabinoid

Beta-caryophyllene is a spicy, peppery terpene found in cannabis, black pepper, cloves and hops, and it's unique because it can bind directly to the body's CB2 receptors, acting a bit like a cannabinoid without getting you high. That's why researchers are studying it for inflammation, pain and anxiety. If you think weed is just about growing any old plant and smoking it, the reality is a lot more interesting.

Plenty of people who want to start growing cannabis run into a flood of information that can get confusing, and even a little intimidating, given how much half-baked info is floating around online.

One of the terms that trips up beginners the most (and, let's be honest, some veterans too) is caryophyllene.

Odds are that, like a lot of curious growers and smokers, you've heard it mentioned in passing. It's got a weird name that can be a bit off-putting. But today we're breaking down what it is, what it does and its many potential benefits.

What is caryophyllene, or beta-caryophyllene?

It's an organic compound classified as a bicyclic sesquiterpene. We know: way too many strange, tongue-twisting words. Stick with us.

This terpene, one of the aromatic compounds that give plants their smell and flavor, shows up in the oils of lots of plants, flowers and fruits, like black pepper, cloves, thyme, oregano and hops, as well as cannabis. It's closely related to two other compounds, and together they're often grouped as three:

1. Alpha-caryophyllene (humulene), found in high concentrations in plants like hops.

2. Beta-caryophyllene, found in high concentrations in black pepper essential oil.

3. Caryophyllene oxide, present in high amounts in plants like eucalyptus. This is reportedly the very compound that police drug dogs are trained to sniff out when they're searching for cannabis.

What does beta-caryophyllene smell and taste like?

Caryophyllene is one of the terpenes that contributes most to the aroma and flavor of cannabis strains, as well as plenty of other plants.

Its aroma is usually described as dry and spicy, but also sweet and woody. Its flavor leans spicier, with notes of wood, camphor, lemon and even fuel.

Caryophyllene properties

Caryophyllene is a big deal among terpenes because of a few unique traits. For example, research suggests it works in synergy with several cannabinoids, which may boost their medicinal effects through the well-known entourage effect.

It also works as an agonist (meaning it can bind to a receptor on a cell and trigger a specific response) of the body's CB2 receptor, so it's a terpene that behaves like a cannabinoid. And because it acts on CB2 and not CB1, research suggests it can have therapeutic effects without producing a high. That's exactly why caryophyllene has been, and still is, widely studied for medical and therapeutic uses.

This terpene also does the plant itself some favors. First off, its natural and main job is protecting the plant that makes it. In that sense, you could call caryophyllene a natural antifungal and insecticide that keeps unwanted invaders away from the plant.

Beyond its benefits for the plant, you'll also find it working as an active ingredient in cosmetics. Caryophyllene shows up in lots of creams, body lotions and gels, serums, products for dry and congested skin, and treatments for acne or oily skin.

Main therapeutic benefits

As we mentioned above, caryophyllene has several properties being explored for everyday medical and therapeutic use. These are the main ones research points to:

Anti-inflammatory: Research suggests beta-caryophyllene has real anti-inflammatory potential. CB2 receptors are involved in regulating inflammation and pain, and when caryophyllene activates them, studies suggest it can help dial down both.

Pain relief: Research suggests it may act on the nervous system to ease pain, especially acute neuropathic pain. Studies also suggest it's more effective in the later phases of pain.

Antidepressant: Animal studies suggest it may have antidepressant-like effects, even in stressful or intimidating situations, and may reduce negative responses.

Anti-anxiety: Several studies, mostly in animals, suggest it helps lower anxiety and stress, and researchers have looked at it as a possible alternative to benzodiazepines, although it's no replacement for prescribed medication.

Insecticide: Research suggests it has strong insecticidal properties that could help against mosquito-borne diseases like malaria, since it appears to repel mosquitoes and disrupt the metabolism of both larvae and adults.

Anti-cancer potential: Lab studies suggest it can influence cancer cell signaling pathways and slow their growth, and it's being studied as a possible complement to chemotherapy.

Main uses of caryophyllene

In many cases its use is still potential, alongside other medications or treatments, but several studies suggest it could help with the following conditions:

1. Multiple sclerosis

2. Colitis

3. Alzheimer's disease

4. As an antioxidant

Advantages of caryophyllene

Besides being a potentially beneficial compound, it seems to be easily handled by the body, and research suggests the following:

1. It acts on the nervous system: research suggests its effects can kick in surprisingly fast, and depending on what you're after, it may be better taken orally or rectally.

2. Few known side effects: according to the research so far, no significant health consequences have been identified, except when it's smoked, but then we're talking about the effects of combustion, not caryophyllene itself.

3. It can be taken orally: we all know someone who has a hard time swallowing pills, whether they're too big or just hard to get down. Research suggests caryophyllene is well absorbed through the lining of the mouth, which is a plus for kids or people with breathing problems.

4. It's non-psychoactive: that makes it a great fit for medical use and as part of specialized treatments.

There's still a lot to research and learn about the huge world of possibilities cannabis has to offer. Caryophyllene is one of those compounds that, even if most people have never heard of it, may offer all the potential benefits we just walked through.

One last piece of advice that's always worth repeating: before you add it to your regular routine, talk to a doctor who specializes in cannabis so they can help you figure out the right dose for your body.
