Terpenes Explained What Are They and How Do They Work

Terpenes Explained: What Are They and How Do They Work?

Have you ever wondered why plants have their unique smell? Well, you can thank terpenes for that!

If this is your first time hearing about it, these aromatic compounds are naturally designed to help plants attract pollinators and repel predators. Harnessed in the form of oil, crafty manufacturers have been using them to create a myriad of products that we use everyday.

Apart from being a common ingredient in fragrances and other beauty essentials, terpenes are a key ingredient in hemp. While it’s not the main component responsible for producing a euphoric feeling, medical studies suggest that a strain’s terpene levels can greatly influence its flavor and effects often referred to as “entourage effect”.

With that said, you probably have a lot of questions in mind. How are they extracted? What are the different types? How exactly do they influence a strain? If you want to learn more about these compounds, the team at Medical Terpenes will be glad to discuss everything you need to know!

How are Terpenes Extracted?

Terpenes can be extracted in multiple ways and each process has its own set of ups and downs. Given that eliminating impurities can be a sensitive and tedious task, the method a manufacturer chooses will ultimately define their end-product. Even though there are several ways to harness these compounds, the results of these extraction methods generally fall into two main categories: solventless and solvent-based. 

Solventless extracts are produced through the use of high heat. 

  • Steam distillation requires you to suspend a container of your chosen plant above a pot of boiling water. As steam whiffs through the plant, oils drip down and is cooled by a condenser afterward. Once the oil floats to the surface, it can be easily extracted and separated.
  • Hydrodistillation also makes use of the principles of heat. It has a similar setup to steam distillation but the main difference is that this method will require you to place the plant into the boiling water. 

The biggest upside of these two methods is that they don’t use solvents (butane/ethanol) that may compromise the extract. However, working with high temperatures can be counterproductive if not done carefully. Boiling or exposing the plant to steam may alter or destroy terpenes completely. 

Solvent-based extracts are harnessed at lower boiling points.

  • Butane Extraction utilizes a special butane solvent. The plant is placed into a small glass container and is exposed to this mixture for some time. Once the liquid has settled, it goes into a comprehensive winterization process and can be extracted without any damages or impurities.
  • Supercritical CO2 is a gaseous substance that’s used as a solvent. Through heat and pressure, it’s converted into a “supercritical state” and is applied to the plant to extract and produce a certain compound. To extract the terpenes successfully, the CO2 can extract the terpenes directly while in a subcritical state.
  • Live resin Expression is a concentrate that’s made by exposing the plant to warm temperatures while pressing the plant to push out the oil and terpene contents inside. This method is popularly known for its ability to preserve a plant’s aroma and terpene content but its biggest downside is that this method takes relatively more time and has low efficiency.
  • Ethanol extraction is a fairly new method that’s still undergoing development. Ethanol is a proven solvent that has both polar and nonpolar properties and this makes it the perfect chemical for drawing out substances. But even though it can extract oils and terpenes with ease, the bad news is that it can also collect impurities just as effectively, proving difficult to completely remove all ethanol. 

Getting to Know Terpenes

As previously mentioned, terpenes are the compounds responsible for producing a plant’s aroma. The essential oil compounds plants contain determine the relaxing scent and effects of lavender, citrus and the other herbs you smell daily. This is the main reason why terpenes are an essential ingredient for different products such as cleaners, perfumes, and more. However, the influence of these compounds doesn’t stop there. 

When it comes to hemp, terpenes play a big role in defining your overall experience. They’re secreted in the same gland as CBD, they are  a completely different substance with their own unique role. Along with the other compounds found in your strain, they work hand-in-hand with them to achieve what’s called the entourage effect

To put things simply, this means that a strain’s terpene content can define its flavor, and influence the reactions brought by CBD. It doesn’t produce the euphoria users generally experience, but it can promote or reduce a strain’s uplifting or relaxing characteristics. By experimenting with different terpene types and concentration levels, manufacturers can create a wide selection of sativa and indica products. 

Nowadays, CBD users can test out different variations to find a strain of their preference.  As you build more knowledge, be careful not to confuse the terpenes with terpenoids. Many tend to interchange the two terms since they sound the same but they mean completely different things.

So you don’t get confused, always remember that terpenes are hydrocarbons and that terpenoids are derivatives of hydrocarbons.
