The days of an outdated and frankly inaccurate cannabis classification system are finally over. The market has blurred the lines between quality and craft cannabis for far too long - leaving customers and cultivators with no real roadmap to identify the range and spectrum of the medicinal possibilities contained within cannabis and the unique entourage effects possible from the diversity that it offers.

Experts consider Cannabis Indica, Sativa, and Hybrid the three main subspecies - the issue is that people have used the THC potency of strains to determine superiority. Measuring potency and the effects with this method is a long-outdated classification system, especially when it does not provide accurate labels for customers and budtenders alike. The words “Indica” and “Sativa” were introduced in the 18th century to describe different species of cannabis, but modern research has led to more information that we will share throughout this article.

Historically, this is how cannabis has been defined;

Strains

Cannabis Sativa

Sativa is supposedly uplifting and cerebral, enhancing creativity and productivity. Indicas provide what has been called a “body high,” while Sativa’s deliver more of a “mind high.” Unfortunately, Sativa plants require longer to grow and yield less medicine (flowers) than Indica varieties. Sativa’s smell sweet, fruity, or spicy. This difference in the aroma results from terpenes, the molecules within the plant that are cousins to cannabinoids like THC and CBD. While these chemicals sometimes provide stunningly pungent odors, their greatest benefit to patients is their medicinal efficacy.

The problem with the general ‘idea’ of what a Sativa does, is that there is no accurate spectrum representing an understandable visual for growers and customers to understand easily.

Cannabis Indica

The typical example of Cannabis Indica is a more compact, thick-stemmed bush than its cousins, usually reaching a height of fewer than two meters. The foliage is generally a dark shade of green, some examples appearing to have almost blue or green-black leaves. These leaves are composed of short, wide blades.

Most Indicas are supposedly a rich source of the cannabinoids THC, CBD, and CBN. While Cannabis Sativa often produces a higher proportion of THC than its other cannabinoids, Cannabis Indica usually contains significant levels of all three. Indicas tend to have more body-centered effects than Sativas – enhancing physical sensations, which is not accurately measured either.

Cannabis Hybrids

Typically, a Hybrid is a cannabis plant with Indica and Sativa characteristics. Because cannabis has been cultivated for centuries, most modern strains are hybrid. Pure Sativas and pure Indicas are rare, so most cannabis you'll find these days is a hybrid.

Hybrid strains typically develop either Sativa-dominant, Indica-dominant, or evenly balanced phenotypes. Strain descriptions usually list it that way or display the split as a percentage. Remember that the terms Indica and Sativa strains are most useful for cultivators in determining growth characteristics like how tall plants will grow or how long their flowering cycle will be. Effects share no apparent connection with today's cannabis plants' physical structure, hence why the classification system is largely outdated.

So why is this a problem?

According to SC labs (SC Labs is a company that offers comprehensive solutions for cannabis and hemp testing) co-founder, Josh Wurzer;

“The problem is that there is little standardization when it comes to defining and determining terpenes”

Measuring the superiority of cannabis is confusing, and frankly, the classification system is completely outdated. It no longer only comes down to the strain. The days of just searching out the highest THC totals are rapidly receding. Research has proven that terpenes are at the base of the entourage effect, where previously, it has been considered ‘minor’ information. Cannabis growers and breeders have been assigning labels to cultivars primarily based on aroma profiles and purported effects rather than genetic ancestry or overall chemical similarity. Cultivators, processors, retailers, and consumers could benefit from greater standardization when evaluating product quality and distinguishing label claims.

Because cannabis is a widely used substance increasingly being legalized for medicinal and recreational use, Cannabis’s genetic and chemical variation must be accurately quantified and communicated. Using strain labels like Sativa and Indica are used to describe a cultivar’s morphology, aromas and/or psychoactive effects. However, whether these labels capture meaningful information about Cannabis's genetic and chemical variation is incredibly unclear. This leaves room for inaccuracy and uncertainty in a world growing in popularity faster than any other industry.

In this study, the inaccuracy of reporting is clear;

“This is consistent with previous studies indicating that cultivar names were not reliable indicators of a sample’s genetic or chemical identity”

The study shows that the genetic structure of cannabis explained only 37% of the variance in labeling, meaning that Sativa–Indica labels do not accurately reflect genetic relatedness. When the study looked at the correlation of Sativa and Indica terpenes and cannabinoids, Sativa content was positively correlated with the concentrations of bergamotene and farnesene. While on the other hand, there were significant positive correlations between Indica labeling and three sesquiterpenes: guaiol, γ-eudesmol, and β-eudesmol. This shows that it goes far beyond mere classification, and it really comes down to far more than simple labels.

The contrasting aromas that have been associated with Sativa (that is, sweet) and Indica (that is, earthy) were key discriminators in a sensory evaluation of Cannabis cultivars and mediated customers’ perceptions of potency and quality.

What is the solution?

Simple; replace the three vague classes with six elaborate and detailed classifications instead. On February 16th, – SC Laboratories, Inc., (SC Labs) announced that it has licensed Napro Research LLC’s proprietary data visualization tool PhytoFacts®. Clients testing cannabis through the lab will now have access to this game-changing reporting format and algorithm that provides a visual profile of each strain’s chemical makeup. This new report format is intuitive and helps budtenders and consumers identify the right strain for their desired effect. As mentioned above, the terpene profile proves to be far more important than the breed of cannabis, which means that companies like SC Labs are putting an end to the days of simply seeking out the highest THC percentage. Science has converged to finally prove that terpenes are at the root of the entourage effect that consumers are seeking.

Always looking to level their playing field and eliminate as much bias as possible, SC labs' owners partnered with the event organizers of Emerald Cup and NAPRO research to help reframe the conversation regarding what defines “quality” in cannabis. The Emerald Cup is widely believed to be the World Series of Cannabis competitions as it is rooted in Humboldt County. The partnership is intended to help revolutionize the collective understanding of the true role of terpene content.

The new classification system focuses on sorting flower entries by primary terpene content, leveraging a combined decade of research into Cannabis phytochemistry between  PhytoFacts® coupled with a powerful database of over 250,000 terpene tests and aggregated by SC Labs, going back to their launch of terpene testing on Cannabis in 2013 as you can see below.

How We’re Using The New System

Because of the reliability and shift in the right direction, Black Tie CBD has made use of the latest testing for our ‘ChemDawg’ strain, as you can see below;

As you can see from the report produced by PhytoFacts®, there’s immense detail about the aroma & flavor, identifying the spectrum of profiles in depth. The particular aroma and tastes lean far more towards earthy with some sweet and fruity profiles. Similarly, the entourage effect is highlighted, giving the budtender or end-user a clear idea of its effects. The relaxation and comfort of the strain are highlighted, with lower energy levels. The report is easy to understand and interpret, and above all the classification is distinct without being confusing.

This goes to show how important terpenes really are, and how the entourage effect varies depending on multiple facets which are not usually shown - including highlights of b-Caryophyllene (3.943 mg/g), Myrcene (3.767 mg/g), Terpinolene (2.605 mg/g). The relevance of highlighting terpenes matters significantly because terpenes have also been identified as a new frontier in cannabis medicine. Until recently, the spotlight has been focused almost exclusively on the therapeutic qualities of cannabinoids, such as THC and CBD, but as our understanding of terpenes grows more sophisticated, it’s becoming apparent that these aromatic compounds are medicinal powerhouses too.

β-Caryophyllene: β-Caryophyllene is generally the most common sesquiterpene in cannabis, and the most abundantly produced terpene in Nature. Over the last decade, it has gained scientific attention after discovering that it can directly activate cannabinoids receptors. Basically, the β-Caryophyllene terpene acts as a cannabinoid.

This is the terpene that contributes to the ever-so-slight spicy flavor, but mainly to the earthy profiles as well as the relaxation quality of this strain.

Myrcene: Myrcene is the most abundant terpene in modern commercial cannabis. Myrcene has many therapeutic benefits. Like other terpenes, myrcene is believed to have potential anti-inflammatory, potential anti-tumor, sleep-supportive, and other health benefits.

Myrcene characteristically gives our cannabis strain a mildly sweet flavor profile and provides scent notes that are spicy, earthy and muskiness - and also contributes towards that relaxing and calm effect that was mentioned.

Terpinolene: Terpinolene, a terpene dominant in about one in ten cannabis strains, is recognized for its woody smell combined with floral citrus notes. In addition to its fresh aroma, terpinolene is known for its antifungal and antibacterial properties. Terpinolene is considered more multidimensional in comparison to other cannabis terpenes.

These combined effects and profiles of terpinolene are why there are more fruity aromas and comforting effects. The combination of all three highlighted terpenes should indicate the importance of a more accurate and science-backed classification system to ensure that all effects, aromas and profiles are accounted for.

Without having to handle the substance, users and budtenders can now have a true discourse about the desired flavor, fragrance, and potential effects of cannabis. Consumers may now finally buy cannabis online with ease thanks to the new classification system and PhytoFact® information.

As you may have learned from our last blog, terpenes are the most overlooked yet arguably the most important aspect of cannabis. They’re a little bit like cannabinoids—THC, CBD, and others—in that they have specific and medically useful interactions with our bodies.

If you aren’t familiar with terpenes; unlike cannabinoids, terpenes are found in many plants; they’re the chemicals that give a plant its aroma and flavor. Different levels of terpenes in different strains of cannabis give it a more earthy, fruity, or skunky smell and taste. In addition to stimulating our senses, many of these terpenes have medicinal effects.

In the last several years, scientists started to speculate about the synergic and/or entourage effects of the other cannabis compounds. Today, in the first row are terpenes/terpenoids, but we’re also focused on talking about flavonoids, flavonoid glycosides, and polyphenols. There are 120 terpenes found in cannabis, but for the sake of time, this article will focus on the 5 most dominant terpenes found in cannabis.

So, what are the top 5 terpenes?

‍

One of the most common terpenes found in cannabis is myrcene (also known as alpha-myrcene or beta-myrcene). β-Myrcene is the most common and a particularly potent terpene and is a component of the hydrocarbon fraction of many essential oils. It occurs naturally in over 200 plants and is present in the emissions of many trees in different parts of the world. Exposure to β-myrcene from natural food sources is estimated to be 16,500 times more than from its synthetic use as a flavor substance.

On average, myrcene represents over 20% of the terpene profile in modern commercial strains, although individual samples vary widely in their terpene content.

Scents and Aromas

Myrcene has a spicy, earthy, musky scent that gives cannabis strains a mildly sweet flavor profile. β-Myrcene is a pleasant-smelling, olefinic, acyclic unsubstituted monoterpene that occurs naturally in many plant species, especially in the essential oils of plants such as hops, cannabis, lemongrass, verbena, and bay, as well as in citrus fruits and citrus juices.

Effects of Myrcene

Antioxidant Activity:

In recent decades, there has been growing interest in the use of naturally occurring antioxidants in food preservation. Antioxidant agents are accountable for preventing aging and degenerative diseases such as atherosclerosis, cardiovascular diseases, cancer, diabetes and neurological illnesses. They also have an important role in inhibiting lipid oxidation within food products.

Anti-inflammatory Activity:

Myrcene has shown anti-inflammatory and anticatabolic effects on human chondrocytes. Cartilage degradation and osteoarthritis progression was slowed down. The anti-inflammatory activity of β-myrcene may not only be credited to its antioxidant potential, but also with its interaction with signal pathway cascades involving cytokines and transcription factors.

Central Nervous System Effects and Neurobehavioral Activity:

In a study, Myrcene in cannabis demonstrated measurable effects on the autonomic nervous system in healthy human subjects. Inhalation of cannabis essential oil for 5 min improved nerve activity and was shown to relieve stress and anxiety, and the subjects generally felt more relaxed, energetic, calm, and elevated mood, five min post inhalation.

Farnesene, also known as Trans-β-farnesene, is a sesquiterpene considered soothing for the mood with calming and sedative effects.  Farnesene is an umbrella term for six different sesquiterpenes which are all chemically similar. There are two types of farnesene: alpha (a) and beta (b), both of which are naturally-occurring in a variety of different plants.

Farnesene is an analog of farnesol and is found in various natural sources, including hops, ginger, turmeric, ylang-ylang, and German chamomile. Another intriguing effect of farnesene is that it acts in many plants as a natural insect repellent, functioning as a pheromone that interacts with various insects. Some studies have demonstrated that aphids release farnesene before the danger of death or when dying to warn their companions of the near threat.

Scents and Aromas

The terpene offers a number of notes, including sweet, woody, berry, fruity, and reminiscent of apples. In fact, that is what the smell reminds of - green apple. Whenever you feel these tones when smoking your fine cannabis, that would be Farnesene.

Effects of Farnesene

Antimicrobial Properties

In some studies, farnesene, in conjunction with other terpenes, has shown antimicrobial activity against some serious types of bacteria, such as Staphylococcus subtilis. Even though the research is limited in this area, using the terpene for this advantage in the human body is no doubt fascinating.

Anti-Cariogenic Properties

Certain types of bacteria in the mouth are directly responsible for causing the tooth enamel to break down and deteriorate. Because of the antimicrobial farnesene effects, terpene may help fight tooth decay. The terpene may be active against Lactobacillus acidophilus, one of the common culprits behind tooth decay.

Anti-Inflammatory Properties

Farnesene has been shown to have prominent anti-inflammatory properties. So much so, that the terpene has been used in the past in place of things like ibuprofen to ease everyday discomforts. The anti-inflammatory actions of the terpene may also be important for future studies in its ability to act against allergic responses.

If you’re a grower who appreciates cannabis with a great terpene profile, you may well have heard of beta-Caryophyllene. It is also known as ‘b caryophyllene’, β-caryophyllene or simply caryophyllene. Ever wondered what the difference is between beta caryophyllene and caryophyllene? There is no difference, they are just different names for the same terpene. It was one of the first cannabis-derived compounds other than THC, CBD, and CBN shown to bind directly to endocannabinoid receptors.

It was one of the first cannabis-derived compounds with a fundamentally different structure from the classical cannabinoids that interacts with the endocannabinoid system in humans. In many ways, beta-caryophyllene is an important reminder that terpenes and cannabinoids are not separate and that the two work in conjunction with one another.

Scents and Aromas

β-Caryophyllene is the primary sesquiterpene contributing to the spiciness of black pepper; it is also a major constituent of cloves, hops, rosemary, copaiba, and cannabis. It’s responsible for the slight bite of pungency associated with smelling cracked pepper.

Effects of Caryophyllene

Sleep

In combination with other terpenes, caryophyllene has shown promise as a sedative. A 2012 study published in the journal Pharmaceutical Biology found that mice treated with essential oil containing caryophyllene experienced increased sleep time as well as decreased locomotion and body temperature.

Beta-Caryophyllene Anti-Inflammatory Properties

Beta-caryophyllene can reduce inflammation in the brain and chemicals that cause oxidative stress associated with inflammation. These properties can aid the brain from swelling during a stroke and improve its outcomes. Besides, it has been shown to reduce gut inflammation.

Beta-Caryophyllene Antibacterial & Antimicrobial Properties

Studies suggest that beta-caryophyllene helps fight bacterial dental plaque build-up and is a potential alternative to prescribed medications like chlorhexidine. Also, it reduces microorganisms like Streptococcus pneumonia, Haemophilus influenzae, and E. coli.

This sesquiterpenoid differs from other terpenes because of its unique structure. Guaiol, sometimes referred to as “champacol,” is most abundantly found in oily timber and resin of the tropical guaiacum plant. Moreover, the cypress tree is also known to be rich in this sesquiterpenoid and other conifers. Guaiol differs from many other terpenes—which are oil-based—because of its unique structure as a liquid.

It is a terpene that conveys an aroma of pine that features fragrant undertones of wood and rose. Like other terpenes, this medicinal molecule is produced by many plants other than cannabis, including cypress pine and guaiacum (an evergreen tree of the Caribbean and tropical America).

Scents and Aromas

Guaiol is responsible for the scents of many plants like nutmeg, tea tree, conifers, apples, cumin, and lilacs. It presents a refreshing piney and woody aroma with some undertones of rose in it. For this reason, guaiol is added to a large variety of foods and household items as an aromatic agent.

Effects of Guaiol

Antibacterial Activity:

A 2017 study entitled “The Essential Oil from the Fruits of the Brazilian Spice Xylopia Sericea A. St.-Hil. Presents Expressive In-vitro Antibacterial and Antioxidant Activity” and published in The Journal of Pharmacy and Pharmacology found guaiol to be effective in treating bacterial infections. The research revealed that this terpene may be useful as an antimicrobial ingredient in food preservation.

Cancer Potential:

A 2016 study entitled “Guaiol Regulates RAD51 Stability via Autophagy to Induce Cell Apoptosis in Non-small Cell Lung Cancer” that was published in the journal Oncotarget found that guaiol is an effective agent against cancer cells, resulting in their apoptosis, which is a form of genetically pre-programmed cellular death in which cancer cells basically kill themselves off.

Terpinolene is one of the many terpenes in the terpinene and pinene family. While they all share the same molecular formula, weight, and construction,  the placement of the double carbon bond differentiates them. This defines their unique synergistic qualities for therapeutic benefits when combined with CBD products.

Besides showing up in many cannabis varieties, terpinolene is also found in turnips and turpentine. For a long while, research scientists believed terpinolene to act as a sedative. This was due to experiments that determined mice inoculated with terpinolene showed a great reduction in muscle motility contributing to sedation.

Terpinolene by any other name is still terpinolene. Because of its wide use, terpinolene is called by many names depending on the industry and application. Below are a few other names used for terpinolene which you may have encountered in many household products:

• δ-Terpinene (delta-Terpinene)
• 586-62-9 [RN]
• (±)-α-Terpinyl acetate

Scents and Aromas

Terpinolene, though, carries an array of smells you might find in cannabis: It’s piney, floral, herbaceous, and even a little citrusy. Like most other terpenes, terpinolene is produced by various other plant species, including apple, conifer, cumin, lilac, mint, nutmeg, parsnip, and tea tree.

Their extractions from plants are the most important components of the essential oils used in herbal medicine, nutritional supplements, and cosmetics. Terpinolene is used as an aroma agent in soaps and perfumes and as a component of some insect repellents.

Effects of Terpinolene

Sedative

A 2013 study showed sedative effects after nasal absorption into the body(Shimoadachi-cho, 2013). Additionally, In a previous study, the Journal of Natural Medicines tested the sedative effects of terpinolene-dense essential oils on mice. After they isolated terpinolene as one of its active ingredients, they then attempted to determine the structural reason why this terpene has sedative effects. Their research found “Comparison of terpinolene analog activities showed that a double bond in the side-chain or pi bonds in the six-membered ring play important roles in the sedative effect.”

Antimicrobial Activity

One study of a terpinolene-dense plant native to Iran states; “The antimicrobial activity of the essential oil was tested against three different bacteria by disc diffusion method and showed maximum inhibitory activity against Gram-positive bacteria, especially Bacillus subtilis.”

Antioxidant Activity

The International Journal of Phytotherapy and Phytopharmacology published a study where the preparation of LDL from human blood plasma enriched in terpinolene was isolated. The lipids of LDL were protected, and the proteins also didn’t experience oxidation, “This inhibition is due to a retarded oxidation of intrinsic carotenoids of LDL, and not, as in the case of some flavonoids, attributable to a protection of intrinsic alpha-tocopherol.”
