If you’ve reached the point in your relationship with cannabis where you find yourself researching which live resin or live rosin cartridges you should buy, chances are you know a bit about terpenes. But, if you want to really dive into the science behind cannabis terpenes and how they affect your experience, read on.
What Are Cannabis Terpenes?
Terpenes are not unique to cannabis and occur naturally in almost every aromatic plant on earth. Botanical terpenes are responsible for much of the aroma and flavor you experience in weed, but they also have unique therapeutic and medicinal properties. Cannabis terpenes – of which there are more than 200 – develop in response to their growing environment in combination with their genetic makeup.
There are two types of terpenes: monoterpenes and sesquiterpenes. In relation to cannabis, monoterpenes are much more volatile and are among the first compounds lost once a plant is harvested. However, you can stop this from happening by freezing the plants right after harvest to preserve their content.
Common monoterpenes include myrcene, limonene, linalool, and pinene. The most common sesquiterpenes are caryophyllene, humulene, longifolene, and germacrene. They have an extra isoprene unit that makes them sturdier than monoterpenes which helps them withstand more environmental changes.
Okay, if terpenes give cannabis its scent, it’s reasonable to think you can just follow your nose to your favorite strain. For example, if you like the smell of freshly squeezed lemons, perhaps you’d enjoy a strain high in limonene. Or, you might choose limonene-heavy strains because they are known to help reduce anxiety and replace it with an upbeat, happier feeling.
Why Are There So Many Terpenes in Cannabis?
Terpenes perform multiple functions in plants. Their two main roles are the protection against insects and herbivorous animals, and protection against high temperatures. Plants react to stimuli by producing terpenes in the areas affected by insects and herbivorous animals. They act as bitter compounds that repel them like a pesticide.
A Natural Pesticide
Monoterpenes dominate in inflorescences (flower) to repel insects. Sesquiterpenes, which tend to be bitter, are more abundant on leaves acting against herbivorous animals. Some terpenes can act as a decoy in certain plants, attracting either pollinating insects or beneficial predatory ones that feed on herbivorous insects. In the cannabis plant, terpenes are contained in the sticky resin glands. Insects are easily trapped and immobilized, preventing them from chewing on leaves or harming them in any way.
Protection From Heat
As plants sense a temperature rise, they begin synthesizing more terpenes. These terpenes evaporate at high temperatures, producing airflow that cools the plant and reduces transpiration (water loss) throughout the peak heat of the day. This is why you might notice that the plants smell stronger during the first morning hours compared to the warmest part of the day.
This is the reason why it is recommended to harvest mature plants during the first morning hours to get the maximum production of essential oil. Additionally, it can be observed in climates that experience significant temperature changes between day and night that cannabis plants will exhibit enhanced terpene content as a result. The same terpenes that generate natural evaporative cooling during the day will not evaporate through cooler nights. This can lead to generally increased terpene content due to volatile compound loss reduction due to cool evening temperatures.
Some manufacturers will blend “botanically-derived” terpenes with liquid THC distillate in an attempt to replicate natural terpene profiles. Unfortunately, these lab-curated, non-cannabis blends often miss their mark regarding strain-specific flavor profiles. Perhaps mother nature knows best.
How Do Terpenes Affect Your High?
Much like cannabinoids, terpenes work within the body’s endocannabinoid system (ECS). This regulatory system modulates several important bodily functions like temperature, sleep, mood, hormones, digestion, and so much more. The ECS contains receptors throughout the body. The CB1 receptors are primarily found in the central nervous system, and the CB2 receptors are primarily found throughout soft tissues and immune systems.
When cannabinoids and terpenes each bind to these receptors, they produce specific effects. When they bind to receptors together, the effects are amplified. The terpenes actually enhance the cannabinoids, and when they work in harmony together, we call this the entourage effect.
What About Synthetic Terpenes?
This is where the conversation opens up to the “known unknown” compounds in cannabis. Although terpenes and cannabinoids are the major players, the supporting cast of compounds found in cannabis ties the performance together. The entourage effect is not moderated by terpenes and cannabinoids alone. Flavonoids, esters, thiols, sugars, and more contribute to the elegant tableau of naturally occurring compounds found in cannabis. Attempting to mirror or mimic a cannabis strain with cannabinoids and terpenes alone is like trying to cook bouillabaisse with only water, salt, and pepper.
Most Abundant Cannabis Terpenes
Although we mentioned that there are roughly 200 cannabis terpenes, we’ll only cover the top seven major terpenes before diving into some of the rare cannabis terpenes. You’ve likely enjoyed cannabis high in these seven types, but here’s how to recognize them the next time you’re enjoying a concentrate.
Myrcene
Myrcene is earthy, musky, and a bit sweet and spicy. Sometimes it’s even citrusy and herbal. It’s quite pungent in larger concentrations, and you’d recognize the scent in a fresh slice of mango. Fun fact: myrcene has been shown to increase the bioavailability of THC, so it’s said that eating a mango before you smoke can lead to a more powerful high. It’s mostly found in indica-dominant strains.

Limonene
Limonene is easily recognizable by its strong citrus aroma. It smells of freshly sliced oranges or a squeeze of lemon in a glass of water. It’s fresh, bright, and instantly makes you feel better. Typically limonene is dominant in strains that have a sativa-like effect. Limonene is an excellent choice for beating the winter blues or kicking a bad mood to the curb.

Rare Cannabis Terpenes
Behind the major terpenes, several rare cannabis terpenes contribute to the entourage effect of each particular strain. Although rare, they are mighty and work alongside dominant terpenes and cannabinoids to amplify the entourage effect.
Valencene
Valencene has a strong citrus flavor (think Valencia oranges), but it’s followed by a woody, herbal aroma and exhale. Because of its strong presence in citrus fruits, it is often confused with limonene.

- Orange
- Grapefruit
- Tangerine
High valencene strains:
- Agent Orange

Eucalyptol
Eucalyptol is minty fresh. It’s used to flavor toothpaste, gum, and tons of cosmetics and cleaning products. High eucalyptol strains are crisp, spicy, and refreshing, and leave you feeling invigorated. Pay attention to the exhale as you might find a hint of honey hiding in there.
Top benefits of eucalyptol:
- Anti-inflammatory
- Antioxidant

- Eucalyptus
- Tea tree
- Wormwood
High eucalyptol strains:
- Super Silver Haze

Bisabolol
Bisabolol is more than a quirky name. It’s quite rare because it’s not widely found anywhere in the world except in chamomile and a special tree from Brazil. And, of course, select cannabis strains. It smells and tastes much like a floral, sweet cup of chamomile tea.
Top benefits of bisabolol:
