The Science of Cannabis Terpenes

What are terpenes?

Terpenes are a class of organic aromatic compounds that are produced by a wide variety of plants. They are the main building blocks of essential oils, and they give plants their characteristic aromas. Also known as terpenoids, they are the most diverse and plentiful naturally occurring chemical compounds. Terpenes play a part in countless health benefits and have a wide range of therapeutic qualities.

Terpenes are responsible for the distinct flavors and aromas of different cannabis strains. Some common flavors include citrus, pine, floral, and earthy. Each strain has its own unique profile of terpenes that contributes to its overall flavor and aroma.

Cannabis cultivars contain more than 100 different isolated terpenes, which are responsible for the plant's distinct smell and flavor. Cannabis strains have unique terpene profiles which contribute to its therapeutic properties.

Plants create terpenes for a variety of reasons. Some terpenes act as attractants for pollinators, while others repel herbivores or predators. Some terpenes also have antibacterial properties, which can protect plants from diseases.

The Cannabis Chemovars

Cannabis chemovars are classified according to their chemical composition. The two main types of cannabis chemovars are indica and sativa. Indica plants are typically higher in monoterpenes, while sativa plants are typically higher in sesquiterpenes.

Taxonomy and localization of cannabis terpenes

The female cannabis plant produces glistening trichomes on the flowers. These trichomes are where the cannabinoids and terpenes are found.

Cannabis terpenes can be divided into two groups: monoterpenes and sesquiterpenes. Monoterpenes are the most abundant type of terpene in cannabis, and they are found mostly in the stalked trichomes of the plant. Sesquiterpenes are less abundant, and they are found in higher concentrations in the sessile, or lower, trichomes of the plant.

Terpene Biosynthesis in Cannabis

Terpene biosynthesis is the process by which terpenes are produced in plants. There are two main types of terpene biosynthesis: monoterpene biosynthesis and sesquiterpene biosynthesis.

1. Cannabis Monoterpenes

Cannabis monoterpenes are produced via monoterpene biosynthesis. This type of terpene biosynthesis involves the formation of terpenes from a single molecule of isoprene. The most common monoterpenes found in cannabis plants include myrcene, limonene, and pinene.

2. Cannabis Sesquiterpenes

Cannabis sesquiterpenes are produced via sesquiterpene biosynthesis. This type of terpene biosynthesis involves the formation of terpenes from two molecules of isoprene. The most common sesquiterpenes found in cannabis plants include caryophyllene, humulene, and bisabolol.

Prominent terpenes

There are a number of different terpenes and other compounds that are found in high concentrations in cannabis sativa plants. Some of the most prominent terpenes include:
Myrcene:
Myrcene is the most common terpene in cannabis. It has a musky, earthy aroma and it is thought to be responsible for the couch-lock effect that some cannabis strains are known for.

Cannabis strains high in myrcene:
Mango Kush
Granddaddy Purple
OG Kush
Bubba Kush
Limonene:
Limonene is a citrus-scented terpene commonly found in lemons, limes, and oranges. In cannabis, it is thought to be responsible for the strain's uplifting and mood-enhancing effects.

Cannabis strains high in limonene:
Sour Diesel
Super Lemon Haze
Tangie
Pinene:
Pinene is a woody-scented terpene that is found in pine trees. In cannabis, it is thought to counteract some of the psychoactive effects of THC.

Cannabis strains high in pinene:

How terpenes affect the body

Cannabis terpenes interact with the body's endocannabinoid system (ECS). The ECS is a system of receptors that are found throughout the body. These receptors are involved in a variety of physiological processes, including pain perception, appetite, mood, and memory.

The two main types of receptors in the ECS are CB1 and CB2 receptors. CB1 receptors are mostly found in the brain, while CB2 receptors are found in the immune system.

Cannabis terpenes enhance the effects of cannabinoids. That means that they can change how cannabinoids interact with CB1 and CB2 receptors. This interaction is thought to produce an entourage effect where the sum of the compounds is greater than the parts.

For example, myrcene is thought to increase the permeability of cell membranes, which allows cannabinoids to bind to CB1 receptors more easily. This interaction is thought to produce the couch-lock effect that some cannabis products are known for.

Limonene, on the other hand, is thought to increase the activity of CB1 receptors. This interaction is thought to produce the uplifting and mood-enhancing effects cannabis consumers look for.

The science behind cannabis terpenes is still in its early stages. More research is needed to understand how these aromatic compounds interact with the body's endocannabinoid system. However, the potential health benefits of these compounds are very promising.

The medicinal benefits of terpenes

Cannabis terpenes are thought to have a wide range of therapeutic benefits. Some terpenes are known to have an anti-inflammatory, stress relief or analgesic effect. Others are known to improve cognitive function and memory.

The science of terpenes is still in its infancy, but researchers have already discovered that these compounds can have profound effects on our health. Here are some of the ways in which cannabis terpenes can improve our health:


1

They Can Enhance The Effects of THC

THC is the primary psychoactive compound in cannabis. It binds to the CB1 receptors in the brain, which leads to the plant's signature high. However, THC's effects can be enhanced by the presence of certain terpenes.
For example, the terpene myrcene is known to increase the permeability of cell membranes, which makes it easier for THC to cross the blood-brain barrier and bind to CB1 receptors. Myrcene is also known to increase the intensity of the high caused by THC.
2
They Can Reduce The Effects of CBD
CBD is a non-psychoactive compound in cannabis that has powerful medicinal properties. It does not bind to CB1 receptors, but it does interact with other receptors in the brain, such as the serotonin receptor 5-HT1A. This interaction leads to many of CBD's therapeutic effects, such as its ability to reduce anxiety and promote relaxation.
However, CBD's effects can be reduced by the presence of certain terpenes. For example, the terpene limonene is known to increase the activity of the enzyme that breaks down CBD. This means that less CBD will be available for the body to use, and its effects will be weaker.
3
They Can Boost The Immune System
Several studies have shown that terpenes can help to boost the immune system. For example, the terpene beta-caryophyllene is known to increase the production of white blood cells, which are essential for fighting off infection
