What Is Caryophyllene In Cannabis?

Notice a unique spicy or peppery kick in the aroma seeping from your curing jars? Chances are you're picking up on the unique scent of caryophyllene, a cannabis terpene renowned for its warmth and spice. Read on for a closer look at caryophyllene, one of the most common terpenes in modern cannabis strains.

What is caryophyllene?

Caryophyllene (or beta-caryophyllene) is a bicyclic sesquiterpene present in cannabis and many other natural substances, such as plants and spices. In cannabis, it is one of the most prominent terpenes, making up between 3.8–37.5% of the essential oil of cannabis flowers (Mediavilla & Steinemann, 1997). Besides contributing strongly to cannabis' unique aroma, caryophyllene is also the only terpene known to bind directly to cannabinoid receptors, and may thereby play an important role in cannabis' effects on the body.

Interestingly, caryophyllene is also thought to affect the sensory receptors of certain insect pests, diminishing their ability to successfully devour plant matter on living cannabis plants.

Smell and aroma of caryophyllene

Caryophyllene has a spicy aroma, and is in fact one of the main contributors to the smell of black pepper. It is also present in herbs and aromatic spices (listed below), where it imparts a warm, spicy, peppery kick. Think of the subtle hint of spice you might detect in the smell of certain hoppy beers, in freshly picked basil or rosemary, or crushed black pepper, caraway, or cloves.

Where can you find caryophyllene?

Caryophyllene is present in many plants and their essential oils. Some common natural sources of caryophyllene include:

• Cannabis
• Basil
• Rosemary
• Oregano
• Hops
• Lavender
• Black pepper
• Cloves
• Caraway
• Cinnamon and malabathrum
• Ylang ylang
• Copaiba oil

Caryophyllene is also commonly used to prepare perfumes, aromatic and essential oils used in aromatherapy, and spice blends made using the herbs and spices listed above. It is also a common ingredient in cosmetics and processed foods.

What is the chemical structure of caryophyllene?

Caryophyllene has a complex chemical structure. It is a large molecule, with a much larger molecular mass than other common cannabis terpenes. Caryophyllene also has a cyclobutane ring, which is very unusual in terpenes and natural compounds in general, as well as two double bonds.

Besides its high molecular mass and unique structure, caryophyllene also has the peculiarity of having a high affinity for cannabinoid receptor 2 (CB2). In fact, caryophyllene has a much higher affinity for CB2 than cannabinoids such as THC and CBN. By binding to CB2 receptors, research suggests that caryophyllene may have clinical potential (see below) without producing the high associated with THC.

Potential benefits of caryophyllene

Caryophyllene is one of the more heavily researched cannabis terpenes, and research suggests it may impact:

• Inflammation and immune response: Research has shown that caryophyllene's high affinity for CB2 receptors may impact inflammatory responses in mice (Scandiffio et al., 2020). Though preliminary, this study opens the door to new research avenues. Furthermore, studies have examined the antibacterial, antimicrobial, and antioxidant potential of beta-caryophyllene (Jha et al., 2021).

• Mood: A 2014 animal study notes caryophyllene’s potential to impact behavioural changes linked to mood, likely through its ability to bind to CB2 receptors (Bahi et al.).

• Bone health: Research shows that beta-caryophyllene may promote the mineralisation of bone tissue while simultaneously slowing the breakdown of old bone cells. As a result, researchers suggest studying caryophyllene in instances of osteoporosis and other bone diseases (Yamaguchi and Levy, 2016).

• Neurodegenerative disorders: Alzheimer's is characterised by the buildup of an inflammatory plaque (known as amyloid plaque) in the PPAR pathway. Studies have pitched caryophyllene against brain inflammation and the buildup of amyloid plaque (Cheng, Dong, & Liu, 2014). Though evidence is inconclusive, any research breakthroughs in this realm are worth pursuing.

• Tumour growth: Many cannabis compounds have been studied for their potential effects on tumours. And beta-caryophyllene is among them, with studies testing its viability in promoting death of tumour cells as well as hindering their growth (Danham et al., 2021).

5 Cannabis strains that contain caryophyllene

Looking for cannabis strains with high concentrations of caryophyllene? Well, you're in luck. Caryophyllene is one of the most common terpenes in cannabis, making up over ⅓ of the plant's essential oils in many cases. Below are some strains with strong, peppery hints, indicative of a high concentration of caryophyllene.

1. Sour Diesel

Sour Diesel is one of the hottest strains to come out of the US. It boasts an unmistakable tart fuel aroma with notable hints of peppery spice and Skunk, and its high concentrations of THC and terpenes give Sour Diesel an uplifting, euphoric, and energetic cerebral high.

Caryophyllene: Summary

Caryophyllene is a terpene present in many spices and herbs, including cannabis. It makes up over 30% of the essential oil of some cannabis flowers, and can be found in many popular strains—both new-school and classic. With a high affinity for CB2 receptors (higher than most other cannabinoids and terpenes), caryophyllene is showing a lot of promise in scientific research.
