Terpene Dictionary

This is a one-page dictionary of 36 of the most common cannabis and hemp terpenes and terpenoids (have the "-ol" suffix). Let us know if you see one in your product that isn't listed here.

Terpenes are important because Indica and Sativa are not actual molecules found in cannabis or hemp. They really only suggest a general tendency toward a terpene profile. They originally indicated a cannabis or hemp cultivar's preferred growing conditions and regions. Since our focus is on active ingredients, we are interested in the actual molecules in cannabinoid products. 

We've got a few other terpene-focused pages, too:

  • For some background info, take a look at our Terpene Overview page.
  • We've grouped these top 36 terpenes by their primary flavor or aroma on our Terpene Flavor Groups page.
  • The Effects & Ingredients page has both cannabinoids and terpenes grouped by their reported effects.
  • Our Cannabis Infographics page has some colorful infographics we created to hopefully make a complex plant a little easier to understand and control for your specific needs and goals.

Remember, everyone has unique biochemistry, so these "average" effects may be different for you. The terpenes and terpenoids in BLUE are reported to be either calming, relaxing, or sometimes a sedative. If you are aware of some references we may have omitted, please let us know.

We have provided links to boiling point temperature references for these terpenes and terpenoids (end in "ol", like linalool, and are considered alcohol compounds). Most of the boiling point reference links are to the US NIH National Library of Medicine's National Center for Biotechnology Information via their PubChem pages here: pubchem.ncbi.nlm.nih.gov. If it wasn't on PubChem, we had to go to several other sources. A few of the other reference sites DO NOT display well on mobile screens (sorry).

ALL boiling points are approximate and are for atmospheric pressure, or 760mm Hg (this is where some mistakes were made in the past).

Here is a colorful infographic with 23 terpenes. The colors indicate whether the terpene is considered more uplifting (red, orange, yellow) or more calming (green, blue and purple). We thank the Emerald Cup for leading the way in this type of user-friendly classification of cannabis and hemp terpenes.

The Top 8 Terpene & Terpenoid List

The first eight (8) are the most common terpenes and terpenoids ordered (roughly) by their prevalence in cannabis and hemp flower. The next 28 terpenes are ordered alphabetically, and generally occur in smaller amounts.

The most common terpene in cannabis and hemp that can make up more than 2% of the weight of some chemovars; also found in mangoes, thyme, citrus, and lemongrass, it has a musky, earthy, sweet herbal aroma. It is largely responsible for the green hop aroma in beer and is a major component in dry hopped beer. A 2021 published review study on Myrcene is here.
