True Terpenes - True High

Terpens together with Cannabidiol (CBD) and Tetrahydrocannabinol (THC) making a big Bazz, scientists have begun to show a growing interest in their research. The understanding of terpenes opens up new levels of research on the effects of marijuana or cannabis, which translates into new research opportunities for growers and seed banks.

 Some influence the brain and produce calm mood, while the others have the converse effect, like raising our energy levels and mood. 

What Are Terpenes?

Terpenes are biomolecules made up of multiples of the isoprene unit (also known as isoprenoids\terpenoid) and can be linear, cyclic, or both. When terpenes are modified with specific reactions that lead to the formation of functional groups that have atoms other than carbon, such as hydroxyl groups, carbonyls or that have nitrogen, are called terpenes.

Terpenes are produced by several plants, especially conifers, and are the main ingredients of essential oils and resins, mixtures of substances that give each flower or plant a very characteristic smell. Plants produce terpene molecules in their resin, for the purpose of deterring predators and attracting the attention of pollinators. Aromatherapy uses terpenes for the therapeutic goal of regulating temperament, solving sleep problems, improving overall health and much more.

Terpenoid v.s Terpenes 

Terpenes and terpenoids are terms used interchangeably.The only difference between terpenes and terpenoids is that terpenes are considered organic hydrocarbons. Terpenoids have additional atoms that have experienced oxidation. This happens when cannabis has been cured and dried. You can think of terpenes as “wet”, while terpenoids are “dried out”.

How Do They (Terpenes) Work?

Cannabis terpenes are formed from the very same glands that make up THC and CBD. Some studies reveal that there is synergy between terpenes and cannabinoids. The first ones conform to the same cannabis receptors that we have in the brain, and that alter the chemical effect that they produce on our body.
However, not all cannabis terpenes work similarly. Some influence the brain and produce calm mood, while the others have the converse effect, like raising our energy levels and mood.
Did you know that consuming a ripe mango a while before smoking enhances the psychoactive and relying effects? The theory is that mango has myrcene, a terpene that you can find only in certain fruits. Myrcene works in synergy with THC and alters its effect.

So what for terpenes used for?

Each individual terpene is associated with unique effects. Some promote relaxation and stress-relief, while others promote focus and acuity. Linalool, for example, is believed to be relaxing whereas limonene elevates mood.

The Most Common Cannabis Terpenes 

Different classes of terpenes can be found in marijuana (maybe more than a hundred); however, their concentrations are of greater significance than their number. For example, when comparing an orange with a lemon. Both the fruits contain a similar kind of terpene called limonene, but in a distinct concentrations. A little variation in the portion is sufficient to make an orange smell different from a lemon.

1. Myrcene

Myrcene is one the most common species of  cannabis terpenes and is part of the most aromatic oils of different varieties of cannabis. You can also find myrcene in other plants, like hops. Some compare the aroma of myrcene with that of the clove. It has anti-inflammatory, antibacterial and analgesic properties. 


The relaxing effect makes it beneficial for stress or muscle spasms. It acts in synergy with other terpenes, potentiating THC as an analgesic, CBD, and linalool as antipsychotics and the antispasmodic effect of many cannabinoids. It also increases insulin secretion by stimulating glucose.

2. Limonene

In addition, limonene can pass the blood-brain barrier with ease and increases concentration and attention. Some products also use limonene to reduce anxiety and depression. Limonene is also a natural repellent for insects; an aromatic terpene that many plants use to defend against predators and insects. Haze varieties are a potential source of this kind of terpene.
