When you open a jar of fresh cut hemp buds, what’s the first thing you’re going to do? Whether seasoned or newbie, that’s right, you are going to take a big whiff of those pretties. That smell, those aromas? The pine, sweet lemon, lavender, grass, gas, musk, skunk, and funk — those aren’t trendy buzz words, those are terpenes.

What are terpenes?

Terpenes are organic compounds that give the cannabis plant their unique smell, taste, and euphoric effects. Found in nearly all plants and fruits (and some other living organisms), these essential oils are part of the chemical makeup that defines a strain’s top notes — the aroma and flavor — and they also contribute to the medicinal benefits of hemp (and for THC strains, the psychoactivity).

What do terpenes do exactly?

The cannabis plant’s 100+ terpenes work together, along with its 60+ cannabinoids, to create a strain’s one-of-a-kind formulation and “entourage effect.” A given strain can have dozens of terpenes — some are sedating or maybe uplifting, some help quell anxiety, some are appetite stimulants, some are appetite suppressants

No strain has just one terpene, but may lean heavily in one direction or another. Often we think of strains in terms of sativa (up), indica (down), or hybrid, but the growing trend in choosing strains (and in research), is terpene concentration. Instead of binary thinking (sativa, indica, hybrid). Think: gradient or color wheel. 

“Most are totally clueless as to how the cannabinoid comes to life in the plant,” says Mike Robinson, founder of the Global Cannabinoid Research Center and editor of Mike’s Medicines blog. “What really amazes me are the number of people that actually grow either small scale or large that simply don’t know how that beautiful cannabinoid is birthed. A concert of biological events occurs as the terpenes create the trichome and CBGa appears — which starts the whole cannabinoid clock ticking!”

“These valuable plant elements cause the endocannabinoid system to light up with activity like it’s the 4th of July.” — Mike Robinson, Global Cannabinoid Research Center 

How do terpenes contribute to the entourage effect?

What’s your favorite meal? Maybe it’s spaghetti or tikka masala or barbecue ribs. A lot of ingredients come together to make that dish what it is. If your sauce is bland — or “one note” — it’s because it’s not balanced with the five tastes (sweet, sour, salty, bitter, umami). It’s the same for terpenes and cannabinoids — a lot of them come together to make the strain what it is. 

And to know your terpenes is to know what your chef — Mother Nature — is cooking up for you. Myrcene is the most common terpene in hemp and it contributes to the calming lean of many indica strains. But once it buddies up — there’s that entourage effect! — with uplifting terpinolene or buzzy humulene, the chill down effect is balanced out and you’re no longer in couch-lock mode. Similarly, myrcene or caryophyllene (the second most dominant terp in cannabis) can mediate a sativa-dominant strain and keep you from heading into a palpitating orbit.  

“What we’ve found at GCRC is the synergy between cannabinoids and terpenes is so significant that the well-known ‘entourage effect’ can occur merely by having multiple terpenes, even with only one cannabinoid involved,” Robinson says. “What we’re learning is that these valuable plant elements cause the endocannabinoid system to light up with activity like it’s the 4th of July. So many thought it took the whole plant and all cannabinoids, but what we’ve found is there’s much more than cannabinoids involved in maintaining homeostasis.”

What are terpenes used for?

Terpenes have many everyday uses and if you go open your cupboard right now, you’ll find a ton — in the spice rack alone you’ve got rosemary, oregano, thyme, basil. Terpenes are found in thousands of household products, pantry staples, beauty products, lotions and sunscreens, essential oils, sleep aids, herbal remedies, insecticides, and industrial items — everything from black pepper to laundry detergent to bubble bath. They are what help calm our anxiety when we do aromatherapy self-care, and if you love the smell of fresh cut flowers in the house, you can thank terpenes. 

Sometimes terpenes give an emotional kick or medicinal benefit, too. You might not know linalool (yet!), but you do know lavender. That sleepy waft that hits you and makes you feel like you are sitting on a cloud in the south of France? That’s linalool. Does the smell of bright lemon oil perk you up? That’s limonene working on those olfactory receptors. 

What are the benefits and effects of terpenes?

We’ll get into some specific terpenes in a bit — and you can download this handy infographic — but there are many benefits of terpenes. Terpenes have been shown to have beneficial properties for body and mind, and can act as an: 

  • anti-inflammatory
  • anti-depressant
  • anti-anxiety 
  • sedative
  • analgesic
  • antioxidant
  • anti-cancer
  • appetite stimulant
  • mood enhancer 
  • antifungal 
  • anti-epileptic
  • antibiotic
  • antimicrobial 
  • antibacterial
  • anti-viral
  • antiseptic
  • appetite suppressant 
  • decongestant
  • expectorant

Mother Nature provides, indeed! 

Are terpenes being studied and researched?

Oh, yes

It’s also a key focus for Robinson and his team at the Global Cannabinoid Research Center. 

“Although it appears we’re very advanced scientifically, we’ve truly just started to learn over the past few decades what cannabinoid medicine can do and how it works – with many of the more intense discoveries on potential being in last few years.”

“In our studies, we find the same type of magic occurring when terpene profiles (multiple terpenes) are combined with a singular cannabinoid constituent,” says Robinson. “Literally the same type, or even better of a dose response, is coming from the patient from terpenes and only one cannabinoid than when only THC and CBD are combined. This is occurring at an even greater level when minor cannabinoids such as CBG, CBGA, CBC, and CBL are used in correlation with specific terpene profiles, which is extremely promising for the future of cannabinoid medicine and nutraceuticals.”

Terpene combinations are becoming a fast-track focus of scientific studies in the MMJ industry and beyond. Robinson points to a study focused on natural terpenoids (Molecules, 2020) found that terpenes play an effective role in, according to the abstract, “immune-mediated inflammatory and infectious diseases, neuroinflammatory, neurological, and neurodegenerative diseases, as well as in cancer and autoimmunity by itself.”  

“It’s our hope at the GCRC that someday we’ll see store shelves filled with easily accessed hemp and other plant medicines, while at the pharmacy there will be the new products that contain plant medicine just like we had 100 years ago,” says Robinson. “Without a doubt, we strongly believe that terpenes will play a key role in developing the most effective ones.”

What are the most common terpenes?

There are 200+ known terpenes in nature, and 100+ in the cannabis plant. But about 10-20 terpenes dominate CBD and MMJ strains, including: myrcene, b-caryophyllene, linalool, pinene, limonene, terpinolene, humulene, ocimene, valencene, geraniol, eucalyptol, camphene, nerolidol, delta 3 carene, borneol, bisabolol — we could go on (and on and on). 

Let’s get into the 8 most common terpenes you might run into when choosing a CBD oil on Irie Bliss or getting a pre-roll at the dispensary.

1. Myrcene

The most dominant terpene in commercial cannabis strains, myrcene has an earthy, musky scent. 


Acts as anti-inflammatory, antibiotic, anti-depressant, sedative, analgesic

Also found in hops, lemongrass, thyme, mangos
