Which Terpenes Are Best for Pain?  - cannabis holds terpenes inside

Posted on June 14th, 2022

Terpenes are classified as aromatic compounds that are present in just about every herb and plant, even though most people seem to link them to cannabis since these plants contain very high concentrations of these compounds.

These compounds create characteristic scents of a variety of plants, including lavender, fresh orange peels, pine, and of course cannabis. The fragrance or scent of a plant is mainly due to these combinations of terpenes. In the wild, terpenes play a role in protecting certain plants from infectious germs or even animal grazing.

They might also provide health benefits for us as humans. As the regulations that once surrounded cannabis have started to ease or fall away, scientists and researchers are starting to discover more about these potential benefits.

Carry on reading to find out more about terpenes, and some of their possible health benefits.

As mentioned above, a terpene is an aromatic compound that often determines the fragrance or smell of herbs and plants. Manufacturers also use “isolated” terpenes to create scents and flavors in common products like foods, body products, and perfumes.

In plants, these compounds play an essential role. For some, they attract pollinators such as bees and butterflies, while in others, they can create strong reactions designed to repel foraging animals or insects. There are also certain types of terpenes that play protective roles in a plant, such as assisting plants to recover if they have sustained damage. Some also play a role in the plant immune system by warding off infectious germs or diseases.

Some people also refer to terpenes as terpenoids. However, they are two different things. A terpene is a compound in its natural form, which means when it is present in a live plant. When we dry and cure a plant, or when processing a plant such as cannabis, the terpenes will oxidize, converting them to terpenoids.

What Are Terpenes And Which Plants Contain Them?

These compounds are extremely abundant and present in just about every type of plant. Some of the more well-known terpenes have turned into household names, yet we have barely begun to scratch the surface when it comes to learning more about these non-intoxicating, beneficial plant compounds.

Some of the more well-known plants that contain these terpenes include:

– Rosemary

– Cannabis

– Lemongrass

– Peppermint

– Tea

– Evergreen shrubs


– Pine

– Spanish sage

– Thyme

– Citrus fruit

To date, scientists and researchers have discovered approximately 20,000 terpenes. Around 150 of them live in the Cannabis sativa plant. From these results, it’s clear that cannabis is not the be-all or end-all when referring to these compounds. While often linked with cannabis plants, terpenes are actually a lot more varied and plentiful in a variety of non-cannabis plants.

The latest catalog of these compounds is already extensive. However, it is very likely that there are still many more to discover. Based on the latest statistics and estimates, scientists have only identified about 20% of these terpenes.

If the species of plants that are still undiscovered contain similar concentrations of terpenes to the plants that have already been identified, there might be 100,000 or more terpenes that are yet to be discovered.

Terpenes play an essential role in a plant’s life, such as acting as powerful magnets to draw natural pollinators. They also act as a defense for some of these plants. Some terpenes act as natural repellents, using their chemical characteristics to generate just the right reaction to repel foraging creatures and insects.

From established studies, it is clear that terpenes play a very active role in nature. Since terpenes play both productive and protective roles over the course of a plant’s life, they are important for the survival of certain plant species. They are also far more than just additions to essential oil or cannabis products, they form a very important part of life systems that have undergone developments over hundreds of years.

The main roles of terpenes in living plants include:

– Warding off infectious germs

– Assisting a plant to recover from any damages

– Attracting pollinators

– Repelling certain predators such as foraging animals or insects
