What Are Terpenes? Cannabis Terpenes 101 — Finest Labs

Terpene is a word not many have heard before, but probably everyone is familiar with, in one way or another.

In essence, terpenes are the aromatic compounds that give plants their aroma.

In addition to plants, certain insects (such as the maize weevil) also produce them to either attract mates or fight off attackers.

If you’ve ever smelled a flower or enjoyed a long walk in the forest just to take in the fresh, aromatic air, then you enjoyed the boosting properties of terpenes first-hand.

So, what exactly are they, and why do people associate them with cannabis?

In this article, you’ll find everything you need to know about terpenes, including why they matter and how they work.

Which Plants Contain Terpenes?

Often, when they hear the words terpenes or terpenoids, people immediately think about cannabis. But that’s not the only plant with a high concentration of them — conifers, sweet-smelling flowers, and many other plants contain them. 

The role of terpenes in plants is much more significant than appeasing humans. Just like with insects, plants use terpenes to attract pollinators or to repel certain predators. Some plants might even use them actively in the healing process or to fight off germs.

Keep in mind that plants can contain more than one terpene. Cannabis is a great example of this, as it is known to have over 100 terpenes. Depending on the variation, the terpenes present in the plant can even go up to 200.

As for terpenoids, they are not exactly the same as terpenes. Terpenoids are the oxidized version of the compound, which results when a plant dries, while terpenes are naturally found in live plants. Many terpenoids form as a byproduct of cannabis processing after the drying and crystallization process of the plant.

Types of Terpenes

Scientists have categorized terpenes according to their molecular formation. 

In other words, each of these categories got its name from the number of terpene units required to form a molecule.

  1. Hemiterpenes (isoprenol, isoprene)
  2. Monoterpenes (geraniol, terpineol, limonene, myrcene, linalool, pinene)
  3. Sesquiterpenes (humulene, farnesene, farnesol)
  4. Diterpenes (cafestol, kahweol)
  5. Sesterterpenes (andrastin A, geranylfarnesol, leucosceptrine)
  6. Triterpenes (squalene)
  7. Sesquiterpenes (ferrugicadiol)
  8. Tetraterpenes (lycopene, beta-carotene)
  9. Polyterpenes (natural rubber)

Terpenes can also be separated by the presence, or absence, of a functional group (terpenes versus terpenoids). 

When a terpene is pure and only contains carbon and hydrogen atoms, it’s considered a terpene. When it contains an additional functional group (such as a hydroxide group), it’s considered a terpenoid instead. 

Both terpenes and terpenoids are common in nature and offer more or less the same benefits. The addition of a functional group may or may not change the ability for compounds to bind or interact with various receptors in the human body — and therefore may alter the therapeutic effects. 

Which Terpenes Are Found In Cannabis? 

Every strain of cannabis has a unique combination of terpenes, which gives them their distinctive aroma. Some cannabis smell skunky; others have more of a citrus or fruity scent.

You may be familiar with the crystal-like formations that appear on the cannabis plant. Those are the trichomes, and they contain resin glands that are responsible for producing terpenes and cannabinoids.

Terpenes act as supporting agents to the cannabinoids in terms of physiological effects. They seem to boost the impact of cannabinoids directly through the entourage effect (by enhancing absorption, slowing breakdown, or interacting with how they bind to receptor sites). However, they also offer their own set of benefits.

Even though cannabis has hundreds of different terpenes, some show up consistently across the various strains. The most common terpenes found in cannabis include myrcene, linalool, humulene, beta-caryophyllene, limonene, pinene, and terpinolene — but there are many others as well.

Terpenes: How Do They Work?

Essential oils used to be the only way we could purposely use somewhat-isolated terpenes. Now they’re sold individually or as blends, and we can implement them in various ways. Similar to essential oils, we can use them topically, orally, or by inhaling. 

You can’t just swallow down terpenes or rub them on your skin, though — you need to use terpenes safely.

How do these small molecules make such an impact? It’s an odd concept and has many people convinced it’s snake oil (fake medicine).

There is science behind it, however. Here’s a glimpse of how terpenes affect our bodies [1].

When we use terpenes, we involve the olfactory system, the digestive system, or the gastrointestinal system, though often more than one is impacted. For example, if you apply terpenes topically, you’ll still smell them. 

When used topically or orally, terpenes can activate gamma-aminobutyric acid (GABA) receptors and transient receptor potential (TRP) channels; inhalation activates olfactory receptors. Fun fact: there are olfactory receptors in the gut, intestine, and skin, but, thankfully these do not sense odors. Can you imagine? Terpenes activate these, too.

These olfactory receptors do cause chemical reactions, however. They stimulate the secretion of hormones and enzymes and adjust blood pressure, to name a few.

Olfactory system activation ultimately sends signals to various parts of the brain, causing the brain to take action, depending on what signals it receives.

Of course, the process is far more complex than this, and we don’t know how deep the implications go. 

Terpenes: What Does the Research Show?

The research surrounding terpenes and their therapeutic benefits are only in the beginning phase. It could be a while before we have any conclusive evidence. However, many studies suggest they have great potential and, at the very least, deserve more research.

While each terpene has a unique effect, many tend to have similar effects. Here are a few ways many terpenes seem to affect our bodies. For a more in-depth look at the research, check out our individual terpene pages. 

Again, not all terpenes demonstrate these capabilities, and there’s not enough research to know the exact impact terpenes have.

Antimicrobial Studies

Many terpenes have antibacterial, antiviral, antifungal, antimalarial, and antiparasitic traits [2, 3,4]. Monoterpenes, in particular, show great potential for their antiviral properties. 

Cytoprotective Studies

Some terpenes seem to have cytoprotective capabilities, especially when dealing with cancer cells [1,5,6]. There are different ways they do this; some suppress the growth of malignant cells or help the body get rid of damaged cells. Others affect cell life and proliferation or inhibit oxidative stress.

Mood Supportive & Anxiolytic Studies

Many people use essential oils for focus and overall improved cognitive abilities. Some terpenes seem to help fight mental fatigue and are uplifting, while others induce sleep and are calming [7,8]. 

A terpene’s effect on mood might go deeper than a superficial “feel good” moment, though. Some, in particular, might help with depression and anxiety, mainly when used alongside cannabinoids [9].

Inflammation Studies

Quite a few terpenes might reduce inflammation, including neuro and respiratory, which can help with certain pain and discomfort [5,10].   

Analgesic Studies

Some studies show terpenes can reduce pain and likely play a minor role in cannabis’ potent effects [6,11].

Neuroprotective Studies

Terpenes might protect the brain from harmful elements like oxidative stress, inflammation, and others [9]. Monoterpenoids and sesquiterpenoids show a high affinity for crossing the blood-brain barrier [12].

Entourage Effect

Some studies show enhanced benefits when cannabinoids and terpenes are used together. This is called “the entourage effect” and suggests that their combination can provide more significant results [8].

Terpenes, in general, are safe, have very low toxicity, and are well-tolerated by most people, increasing their potential for future use for many treatments [5].

Cannabis Terpenes vs. Botanical Terpenes

The term “cannabis terpenes” gets thrown around a lot, but what’s the difference between those and botanical terpenes?

Cannabis-derived terpenes come from cannabis, while botanical terpenes come from all other plants. While it sounds like terpenes from cannabis should be special, they aren’t — not when the extraction process is done correctly. Why?

A properly extracted terpene means there’s nothing but terpene in the final product. The source doesn’t change the terpene’s structure, function, or anything else. Linalool is the same whether it’s from cannabis or lavender. There’s no “entourage effect” because of the cannabinoids — there shouldn’t be any cannabinoids left over. 

Why the fuss over them? Clever marketing.

If you want to benefit from cannabinoids and terpenes, you need to buy a product specifically for that. Figure out what you’re hoping to gain, and go from there.

Cannabis Extracts & Terpenes

Not all cannabis products contain terpenes, just like not all terpenes contain cannabinoids. However, many of the products derived from cannabis and hemp contain terpenes, as they occur naturally in the plant.

CBD oil is an excellent example of the diversity available. If you want a CBD oil that has terpenes, you should look for full-spectrum products. 

Types of cannabis extracts and their terpene concentrations: 

  • Full-spectrum products refer to extracts that maintain all the plant’s active ingredients, including terpenes and THC. 
  • Broad-spectrum products have all active ingredients minus THC. 
  • Isolates contain only one active ingredient, such as pure CBD or pure THC (no terpenes).

Key Takeaways: What Are Terpenes?

Terpenes are everywhere in nature — they are the part that gives plants their specific aromas. Although most people only associate them with cannabis, lavender and hops are just a few of the many other plants rich in terpenes. Almost every plant surrounding us has them, and they are essential to our daily lives.

Their bioactive properties help us in many ways, vastly increasing our quality of life. Terpenes are a great supplement to traditional medicine.
