Terpenes in Cannabis: A Patient Overview

As a superfood, cannabis shares a lot of the same healing substances that other healing plants do. For example, cannabis contains phytonutrients just like sulforaphane-rich broccoli sprouts and resveratrol-heavy dark berries do. What sets cannabis apart, however, is the fact that, when it comes to healing, it is a true chameleon in the best sense of the word. The reason why it has such an effect on so many conditions is due in large part to the presence of terpenes within the plant and how these terpenes interact not only with other substances in the plant but with our own bodies through the endocannabinoid system.

What is a Terpene and Why Should I Care?

Terpenes in cannabis is a subject that is gaining significant attention in the medical world. It is now emerging that terpenes play an important and indispensable role in cannabinoid-based therapeutics. In simpler terms, terpenes are an integral part of medical cannabis. This is what makes it very important to understand terpenes for what they are and how to exploit their potential through the entourage effect.

Terpenes are what creates the unique aromatics of certain plants and gives them their “signature smell.” They are also the basis for essential oils therapy, another powerful healing modality.

Citrus fruits, for example, smell the way they do because of the limonene, a type of terpene that occurs within them. Cannabis strains that have limonene as a dominant terpene will have a dominant citrus smell. Lemon OG is a good example of such a strain.

Plants use terpenes to protect themselves from destructive insects, grazing animals, fungus and other harmful invaders. These “invaders” are put off by strong and unpleasant scents from some terpenes.

Terpenes are not only found in cannabis but they are also present in numerous other plants. Sweet smelling terpenes attract insect pollinators in plants that are pollinated in this way.

As essential nutritional substances, humans need terpenes as well to maintain health. Why do you think that nutritionists and doctors have proclaimed that the healthiest diet in the world is the Mediterranean diet? In part, it has to do with the terpene levels common in these foods.

Pinene can be found in pine nuts, caryophyllene in oregano and peppers and limonene in lemon zest. Because the Standard American Diet (SAD) is lacking in so many essential terpene substances, this is causing a deficiency in terpenes in most humans.

True to form, the cannabis plant does not just settle for one or two kinds of terpene to express, like rosemary or lavender does. Scientists, researchers and growers have discovered over 200 different kinds of terpenes in cannabis; some give off a unique odor and some do not. Of course, as growers and consumers get more specific in what kind of plants they want and need, the number of terpene combinations (i.e. strains) increases.

So why should you care about terpenes in cannabis? For two reasons. The first one is simple, terpenes influence how your body experiences the cannabinoids (such as THC and CBD) in cannabis. Allow us to use this “overused” example: if you are driving a car, the concentration of cannabinoids will determine how fast you go while the terpenes will determine how smooth the ride will be. So we ask, what’s the point of going fast if the ride is bumpy all the way?

For example, myrcene amplifies the effects of THC when it is present in a strain. Mangoes are a rich source of myrcene. Consuming mangoes an hour or so before using cannabis can result in a stronger THC effect.

The second reason is that terpenes have therapeutic benefits that can be harnessed to provide healing.  On most occasions, the kind of terpenes within the plant usually correlate with specific healing effects of the cannabis strain.  If you want to be targeted in healing your particular condition with cannabis, you will want to know what kinds of terpenes are in the marijuana you are currently using or are considering. The healing properties of terpenes in cannabis cannot be fully elucidated without a mention of the entourage effect.

The Entourage Effect

The “Entourage Effect” in cannabis therapy is the science of how terpenes and cannabinoids interact to treat specific diseases and conditions. The concept (and the phrase) was introduced in the late 1990’s by S. Ben-Shabat and Raphael Mechoulam of Hebrew University of Jerusalem.

Several years back, pure isolates were considered as the gold standard for cannabinoid- based medicine. Having a pure and concentrated form of THC or CBD was the epitome of high-quality cannabis treatment. Recent research has however challenged this belief.

In 2015, researchers from the Hebrew University of Jerusalem carried out a study to investigate the entourage mechanism. The study, which was  titled “Overcoming the Bell-Shaped Dose-Response of Cannabidiol by Using Cannabis Extract Enriched in Cannabidiol” confirmed the value-addition that whole plant medicine has over pure isolates.

When a person’s starts consuming CBD or THC, the effects of the cannabinoid will increase progressively over time until a certain climax is attained. At this point, the effects plateau and they may even start decreasing with subsequent additions of the cannabinoid. Adding more CBD or THC will not have any added advantage. A bell shaped curve is formed which shows how the effects of cannabinoids taper off over time, after getting to a climax. However, when a whole plant extract is given, the effects are sustained and do not taper off. Therefore, this study proves that  a full plant extract (containing extra cannabinoids and terpenes) provides a healing effect that is more powerful and prolonged than the one that is provided by an isolate. This forms the basis for the entourage effect.

The Entourage Effect is described as the end result of combining the different bioactive components in cannabis which includes cannabinoids, terpenes, flavonoids, and nutrients. As research has shown, the entourage effect provides a powerful and sustained healing effect that is greater than the sum of the individual parts.

The chemical composition of different cannabis strains will vary greatly. This partly explains why one ‘strain’/cultivar might produce a different effect from another.  This Entourage Effect is the notion that the phytocomplex (the group of chemicals in the plant) are more effective in unison rather than when used in isolation. A full-spectrum CBD product will provide a more powerful healing effect than a CBD isolate.

Terpenes are seen as playing the second most important role in the Entourage Effect. When we are talking about the entourage effect, think of the operating functions of a vehicle. Cannabinoids such as THC or in this case CBD act as the engine which will get you moving. Terpenes are the steering wheel to that vehicle steering you in the direction of where you want to end up.

There are over 400 chemical compounds in a typical cannabis plant so while terpenes aren’t the only factors in determining a particular effect, they are definitely “major stakeholders” needed to achieve targeted healing. Other compounds that play a part in the overall “Entourage Effect” include esters, lactones, ketones, fatty acids, alcohols and steroids, just to name a few.

Breaking down Terpenes and Terpenoids

Terpenes are naturally occurring hydrocarbons based on combinations of the isoprene unit.  Terpenoids are related compounds that include oxygen functionality or some rearrangement.  However, the two terms are often used interchangeably.

There are also hemiterpenes, monoterpene, and sesquiterpenes.

Hemiterpenes – are derived from just one Isoprene unit
Monoterpenes – are built by two isoprenes
Sesquiterpenes – are built by three

There are many debates within the cannabis and CBD industry in reference to these three terpenes as the distinguishing difference in sativas versus indicas.

In nature, there are about 50,000 different terpenes. Cannabis sativa has close to 250 unique terpenes that have been identified to date.  However, just a handful have been investigated for their therapeutic potential.  These are about 25 terpenes that are divided into primary and secondary terpenes.

Primary and Secondary Terpenes

Cannabis strains can be divided into primary and secondary terpenes. Primary terpenes determine how the plant looks, taste, and the unique aroma it gives off. They also participate in the healing properties of the strain.  Secondary terpenes support and enhance the qualities of the primary terpenes.

The interplay between the primary and secondary terpenes will determine how users will experience the particular strain of cannabis. When choosing a cannabis strain, it is important to know which primary and secondary terpenes are present and understand their qualities and how this will influence your experience of the strain. Below is a detailed overview of the primary and secondary terpenes in cannabis.

Primary Terpenes in Cannabis and What They Do

As mentioned above, primary terpenes provide the unique aromas and healing effects that are primarily associated with cannabis strains. Here is a list of 9 primary terpenes that you are likely to come across as you look through the terpene profiles of different cannabis strains.

Myrcene

Myrcene is the most dominant terpene in most cannabis strains. In some strains it makes up to 60% of the terpene profile. It is found in high concentrations in hops, mangoes, sweet basil and cannabis.

Myrcene Aroma: earthy, herbal, skink-like

Myrcene effects: it acts as a calming agent for the body; as such it is a helpful substance for fighting insomnia. It also determines how much THC will eventually arrive and “lock in” to our neuro-receptors. Some theorize that this is done through myrcene’s ability to change the permeability of cellular membranes in order to allow THC and CBD to leave the bloodstream.

Myrcene is also vital for the formation of other terpenes.

One of the most important therapeutic benefits of myrcene is its use as an antibiotic (it helps to catalyze this potential in other terpenes it comes into contact with as well).

It is also an analgesic, antispasmodic, antibacterial, can assist in balancing diabetic conditions, can aid in soothing inflammatory responses and shows promise as an inhibitor of cellular mutations like cancer.

Strains with high amounts of Myrcene:

Purple Urkle
Harlequin
Blue Dream
OG Kush
Tangie

Pinene

Pinene is a common terpene that derives its name from its “piney” scent. The most common form of vegetation this terpene can be found in is, of course, pine trees. It is also found in high amounts in turpentine, rosemary and cannabis.

Pinene Aroma: pine-like, herbal

Pinene Effects: pinene is significant for the endocannabinoid system because it forms the basis for the CB2 ligand, according to a study published in the British Journal of Pharmacology in 2011.  Other studies show that pinene is beneficial for respiratory conditions, pain relief, calming inflammatory responses, and for fighting cancer.

It also appears to play a role in memory retention. Several studies have linked improved memory retention in Alzheimer’s patients to THC in certain marijuana strains. Some speculate that the way in which pinene and THC works together plays an important part in this particular effect.

Strains with high amounts of Pinene:

Double Dream
Grape Ape
Pineapple Express
Citrus Sap
Cannatonic
Harlequin
Shark Shock

Limonene

Limonene is most known for its presence in citrus fruit and for its one-of-a-kind tangy-bitter odor and taste. It is found in high amounts in fruits like lemon, orange and grapefruit, and spices such as rosemary, peppermint, and juniper. It can also be found in many different strains of cannabis.

Limonene Aroma: Citrusy, sweet

Limonene Effects: Limonene is a powerful healer by itself and also has a great effect as part of the “Entourage” for cannabis therapy. Therapeutic effects include digestive relief, anti-fungal, a natural treatment for anxiety and depression, and a powerful stimulator for the immune system. This last effect makes it a powerful ally in healing cancer, something that scientists have been studying for years.

Strains with high amounts of Limonene:

Lemon Haze
Durban Poison
Jack the Ripper
Lemon Meringue
Lemon OG
Black Cherry Soda

Linalool

Linalool is a terpene that is most known for its presence in the relaxing herb lavender, which has been used as a sleep aid for thousands of years. It is abundant in Kush strains where it offers mood-elevating qualities.

Linalool Aroma: lavender-like, tropical, floral, spicy

Linalool Effects: 

Linalool is vital for the production of many essential elements in the body, including vitamin E. Besides its ability to calm the nervous system for stress reduction, Linalool is known as an anti-inflammatory. It has also shown promise as an anti-seizure/anticonvulsant agent. A 2010 Brazilian study of three types of linalool terpenes in mice found that all three helped dissipate convulsive responses. Could the presence of linalool in some strains of cannabis add to its known effectiveness for pediatric seizures and seizures in adults? Hopefully time (and research) will tell.

Strains with high amounts of Linalool:

Dos-si-Dos
Kosher Kush
Lavender
Grandaddy Purple

Humulene

Humulene is most prominently found in hops as well as sage, coriander, ginseng and cannabis. It is similar to Myrcene in many ways.

Humulene Aroma: herbal, musky

Humulene Effects: this is a sesquiterpene and, as such, is a powerfully healing substance. Like many terpenes, it also has anti-inflammatory and analgesic effects. It has shown to be an appetite suppressant and can help with allergies.

Humulene may also have an effect on promoting cancer cell apoptosis (cell death) through something called the Reactive Oxygen Species (ROS). More studies are needed to determine just how humulene affects this process to help fight cancer.

Lastly, Humulene has antiinflammatory effects on the respiratory tract which makes it suitable for treating allergic inflammation of the airways.

Strains with high amounts of Humulene:

Candy land
Original Glue
Death Star

CBD Terpene Tinctures

You are probably thinking to yourself, “OK, this is interesting but what does this have to do with me?”  While it may not seem useful to you, here’s why it should matter.

CBD Terpene Tinctures may have some health benefits.  If you’ve ever gotten a massage with scented oils or taken a bath with lavender, or used aromatherapy products, then terpenes matter to you.  They affect your mood, can alter your mental state, and help you to relax and remain calm.  Topically applied, terpenes may also have some benefits by helping to relieve discomfort in muscles and joints.

Final Note

So there you have it, yet another component of the miraculous healing plant called cannabis. As this series comes to an end, we hope that you now have a better understanding of how cannabis works with the body through the endocannabinoid system as well as how the various substances — namely THC, CBD and terpenes—work together to create balance and healing in your body.

When choosing the right strain of cannabis for your health needs, you should consider terpenes as well as cannabinoids. Many medical cannabis dispensaries list the terpene content of each strain, and a trained budtender can help you find a strain that has higher amounts of the terpenes that will help you most.
