Definition and importance of terpenes in marijuana
Terpenes – subtle plant essences at the heart of the aroma and taste of marijuana. They are what give this plant its characteristic, often intense scent and bring to mind associations of juicy citrus, pine, resin forests, and even sweet ice cream in various flavors. These organic compounds occur in many plants and their importance goes far beyond just taste and smell - they are key elements influencing the interactions of plants with the environment, as well as influencing the human body.
What do we really know about terpenes?
Terpenes are compounds hydrophobic, which constitute a diverse group of organic molecules that are the product of biosynthetic pathways of components such as isoprene. Thanks to their antiseptic, anti-inflammatory and even relaxing properties, terpenes have served humans for centuries as natural remedies.
Terpenes in the context of cannabis
In the context of marijuana, terpenes are like the masters of the orchestra, working closely with cannabinoids such as THC or CBD, creating unique combinations. These combinations affect more than just the general ones smell and taste sensations, but they can also modulate action psychoactive and therapeutic potential this plant. They, following the path called the entourage effect or the entourage effect, enhance or change the effects of cannabinoids, offering a wide range of application possibilities both in medicine and industry.
Variety of terpenes and their impact on the properties of marijuana
The diversity of terpenes is staggering – there are hundreds of them, and each has its own unique “identity” and effects. Among them are compounds such as myrcene, which is famous for its calming properties, limonene with a refreshing, citrus aroma, or pinene, which gives a feeling of opening the airways. All of these compounds are still being researched for their potential health benefits - from relieving pain, to fighting inflammation, to reducing anxiety symptoms.
The role of terpenes in the plant
The role of terpenes in the interaction of plants in the natural world is as fascinating as their impact on the human body. In the plant and animal world, terpenes often play a role defensive function, repelling pests and pathogens at the same time attracting pollinators, which is crucial for plant reproductive processes. In the case of marijuana, terpenes may also contribute plant immunity to extreme environmental conditions and the fight against diseases.
There is a whole spectrum of potential interactions of terpenes with the human body. They are found not only in marijuana plants, but also in fruits, vegetables and other plants. Terpenes can affect our health by entering our body, e.g. through the respiratory tract. They interact, among others: with the endocannabinoid system, which plays an important role in regulating functions such as mood, pain, appetite and sleep.
The effect of terpenes
Learning about terpenes and understanding their action opens new horizons in the field of botany, pharmacology and holistic medicine. Knowing about these compounds also helps understand why some plants, including some strains of marijuana, have a calming effect, while others can stimulate or increase concentration.
The main terpenes found in marijuana
When examining marijuana terpenes, the most common substance you come across is myrcene.
Terpenes are extremely important compounds contained in marijuana. They give it unique scents and influence the experience of using it. Below you will find the main terpenes that can be found in cannabis, their sensory characteristics, physiological effects and potential applications.
MYRCENE – nthe most common terpene in marijuana
myrcene is one of the most common terpenes in marijuana. It is characterized by an earthy, herbal scent with notes of cardamom and cloves. Its effect is considered calming and relaxing.
Research suggests that myrcene may support the treatment of insomnia and pain thanks to its sedative properties. It may also support the absorption of other terpenes and cannabinoids by increasing the permeability of cell barriers.
LIMONENE – a citrus terpene in marijuana
limonene is a terpene with a bright, citrus aroma that resembles the smell of lemon or lime peel. It is known for its mood-enhancing and refreshing properties, as well as its potential antidepressant and anti-anxiety benefits. Moreover, limonene has antifungal and antibacterial properties, which makes it a valuable ingredient in natural cleaning preparations and cosmetics.
PINEN – a terpene responsible for the pine aroma
Pinien is another terpene present in marijuana that is distinguished by its fresh, pine scent. It is believed to have a bronchodilator effect, which may be helpful for people with respiratory problems such as asthma. Pinene also supports concentration and memory, which makes it an interesting terpene for research in the context of memory disorders.
LINALOOL – sweet floral terpene
Linalool it has a sweet, floral scent reminiscent of lavender and is associated with reducing nervous tension and anti-stress effects. Potential uses of linalool include the treatment of anxiety and depression, and its analgesic and anti-inflammatory effects. This terpene is also being studied for its effects on the immune system and possible neuroprotective properties.
CARYOPHYLENE – spicy, peppery terpene
Also known as beta-caryophyllene, it has a spicy, peppery aroma and is the only terpene that binds directly to CB2 cannabinoid receptors in the human body. Thanks to this, it has promising anti-inflammatory properties and may potentially help in the treatment of arthritis and autoimmune diseases.
HUMULEN – woody, herbal notes in hemp
It is also found in marijuana humulene, which shares some of the olfactory characteristics with myrcene, but leans more towards woody and herbal tones. It has anti-inflammatory properties and is used to treat allergies.
Marijuana terpenes – each unique and one of a kind
Each of these terpenes, although found naturally in many other plants, performs specific functions in marijuana and can affect the body in various ways. These effects are intensively studied in the medical context in order to better understand and exploit their therapeutic potential. Moreover, different combinations of terpenes within individual marijuana strains can lead to synergistic effects, significantly modifying the effects of use.
Understanding the mechanisms of action and potential applications of these compounds is crucial not only for marijuana consumers, but also for the pharmaceutical and cosmetics industries looking for new, natural active ingredients. Terpenes, as components of marijuana, are part of a broader spectrum of research on the impact of this plant on human health and well-being.
Terpene extraction techniques
Steam distillation of marijuana terpenes
Terpene extraction is the process of separating these valuable compounds from other elements of the plant, e.g. marijuana. Extraction allows the properties of terpenes to be used for both purposes medicalAnd industrial. Extraction techniques must be well thought out to ensure that the structure and properties of the terpenes are preserved. Among the various extraction methods, the most common are steam distillation; extraction using solvents, and supercritical methods.
Steam distillation of terpenes
Steam distillation is one of the oldest and most traditional methods of terpene extraction. This process is based on the use of steam to separate volatile compounds from plant material. In practice, the raw plant mass is placed in a distillation chamber and then hot steam is passed through it. Terpenes, having lower boiling points than other plant components, are converted into gas together with the steam and directed to the cooler, where they are condensed and separated from the water.
Steam distillation is effective at isolating terpenes, but it is not without its drawbacks. The main disadvantage of this method is the potential damage to delicate terpenes due to the high temperature of the steam. Additionally, some terpenes may not distil at standard pressures and temperatures, limiting the possibilities of this technique.
Extraction using solvents
Solvent extraction is another popular method that involves using chemicals to dissolve terpenes and then separating them from the rest of the plant material. Solvents such as butane, propane and ethanol have the ability to extract terpenes from ground marijuana flowers. After filtration, the solvent is evaporated, leaving behind a concentrated terpene-rich extract.
The problem with this method may be that traces of solvent are left in the extract, which is potentially harmful to the health of consumers. To ensure safety, these products must be subjected to rigorous quality tests. Nevertheless, extraction using solvents is efficient and allows obtaining extracts with high potency.
Supercritical methods
Supercritical extraction, often performed using supercritical carbon dioxide (CO2), is a modern method of obtaining terpenes. In this state, CO2 retains the properties of both gas and liquid, which allows it to effectively penetrate plant material and extract terpenes without damaging their structure. After the process is completed, CO2 is recovered and terpenes are released without the presence of solvents, which makes this process very safe and ecological.
However, the equipment required for supercritical extraction is expensive and complex to operate, making this method less accessible than steam distillation or solvent extraction. Despite these obstacles, supercritical extraction is considered the gold standard in producing terpene extracts of the highest quality and purity.
Terpene extraction – summary
Each of the mentioned methods affects the final quality and purity of the obtained terpenes. While traditional methods such as steam distillation may be less effective and subject to the loss of some compounds, modern techniques such as supercritical extraction achieve a high degree of purity with minimal impact on the terpene structure. Therefore, the choice of the appropriate terpene extraction method depends on the goals you want to achieve, technological possibilities and quality standards of the final product.
The "entourage effect" and marijuana terpenes
The entourage effect, from the French for “companion effect,” is a phenomenon that describes the synergistic effects of marijuana’s chemical compounds, which together affect the human body in a more complex and potentially beneficial way than either alone. This idea, while still requiring research, has gained popularity among marijuana scientists and users seeking a more complete understanding and potential therapeutic use of the plant.
The importance of the entourage effect in the context of terpenes and cannabinoids
Marijuana contains hundreds of compounds, including cannabinoids such as THC (tetrahydrocannabinol) and CBD (cannabidiol), as well as a wide range of terpenes that are responsible for the plants' unique aromas and odors. While cannabinoids have been a primary focus of research interest due to their pronounced psychoactive and therapeutic effects, terpenes also play an important role by modulating and enhancing the effects of cannabinoids.
As an entourage effect, terpenes can affect receptors in the body's endocannabinoid system (ECS), which is responsible for regulating various physiological functions such as mood, pain, appetite, and sleep. Various terpenes can intensify or reduce the effects of cannabinoids on these receptors, as well as affect other neurochemical systems, resulting in unique therapeutic effects.
Examples of synergy between terpenes and cannabinoids
- Myrcene is considered a terpene that may increase the permeability of the blood-brain barrier to cannabinoids, potentially enhancing their psychoactive effects.
- Limonene has antidepressant and anxiolytic properties. It may support the effects of CBD and other cannabinoids in the treatment of anxiety and improve mood.
- Caryophyllene, a selective CB2 receptor agonist, may have anti-inflammatory and analgesic effects, which is particularly beneficial when combined with CBD.
Research on the entourage effect
Scientific research on the entourage effect is still in its early stages, but some results are promising. For example, a study published in the British Journal of Pharmacology (Russo, 2011) suggests that terpenes, by interacting with cannabinoids, may help treat pain, anxiety, inflammation, depression and infection, and may also have anti-cancer properties.
However, the difficulty of studying the entourage effect lies in the complexity of marijuana's plant chemistry and the multitude of compounds that can influence its effects. Moreover, the isolation and analysis of individual terpenes and cannabinoids, and then the study of their interactions, require precise research methods and advanced analytical techniques.
Research conclusions
Although the scientific evidence is promising, there is still a need for further, more detailed research on the entourage effect and its impact on the potential therapeutic properties of marijuana. Nevertheless, the current findings highlight that for both medicine and marijuana users, it is not only the amount of THC or CBD that matters, but also the terpene profile, which can significantly influence the experience and benefits of its use.
Accepting the existence of the entourage effect and a deeper understanding of how terpenes and cannabinoids interact could have important implications for breeders who strive to create marijuana strains with specific characteristics and for producers of marijuana-based products who can better tailor their products to consumer needs.
