As knowledge of cannabis composition continues to increase, there is a growing emphasis on terpene analysis. These additional compounds can increase flavor, taste, and even affect various medical conditions that users may have.[1] However, one of the most pressing concerns
about terpenes is how best to maintain their concentration within any particular cannabis product. Terpenes can be sensitive to light and heat, and they all have what are called burning or boiling points.[2] These are the temperatures at which any particular terpene starts to break down. As they are some of the most sensitive compounds, it is possible that they may burn off through stages of production. By analyzing the burn points from ten of cannabis’s most common terpenes, it becomes easier to see how much potential each one has to be lost before reaching consumers.
Myrcene
Myrcene is one of the most common terpenes found in cannabis, and can make up as much as 65% of some strains’ terpene profiles.[3] It is characterized by its musky and earthy aroma, and due to its anti-inflammation properties is common for strains prescribed to cancer patients. Myrcene has a very high burning point and doesn’t burn off until it reaches 166 degrees Celsius (330 degrees Fahrenheit). This may be one of the reasons it is so prevalent, as it requires high heat to remove.
Limonene
Limonene is the second most common terpene in cannabis, and, as the name suggests, often provides a citrus scent to various cannabis strains.[4] Similar to myrcene, it also has a very high burning point, at 177 degrees Celsius (350 degrees Fahrenheit). Strains with the words “lemon” or “sour” in the name tend to be high in limonene content, which is famous for its mood-elevating properties.
Linalool
Linalool is a terpene commonly found in strains that are useful in a wide variety of medical maladies, including depression, cancer, and insomnia due to its strong sedative effects.[5] It is partially responsible for giving cannabis its herbal aroma, and it has the highest
burning point on the list at 198 degrees Celsius (388 degrees Fahrenheit).
Beta-Caryophyllene
Beta-Caryophyllene, which provides a spicy aroma similar to black pepper or basil, is one of the few terpenes that binds directly to cannabinoid receptors (specifically CB2 receptors).[6] This means it is a terpene that is commonly featured along with CBD products, often for anti-inflammation and antianxiety relief. Beta-Caryophyllene has a burning point of 119 degrees Celsius (246 degrees Fahrenheit).
Pinene (Alpha and Beta)
Pinene is one of the most discussed terpenes in cannabis for its vast medical applicability.[7] As the name would suggest, this terpene gives cannabis the “pine tree” type smell, and has a burning point of 156 degrees Celsius (312 degrees Fahrenheit). This terpene has been linked to
anti-inflammation, increased airflow, and possibly reducing the harmful effects of THC memory loss.
Alpha-Bisabolol
Alpha-bisabolol has strong anti-inflammatory principles and is often used to help with irritation and treat bacterial infections.[8] With a pleasant floral aroma, this terpene has a burn point of112 degrees Celsius (235 degrees Fahrenheit).
Eucalyptol
Eucalyptol is the primary terpene found in the eucalyptus, which provides a cool and minty smell.[9] It is quite rare in cannabis, as only about 0.06% of strains actually contain it. Those that do, though, have demonstrated potential as anti-inflammatory and anticancer treatments. Eucalyptol has a burn point of 49 degrees Celsius (176 degrees Fahrenheit), lower than water’s boiling point and the lowest on this list.
Trans-nerolidol
Trans-nerolidol is another flowery-smelling terpene, and it has been compared to jasmine, tea leaves, and lemongrass.[10] Certain strains like Skywalker OG and Super skunk have high concentrations of this terpene, which has a burning point of 145 degrees Celsius (293 degrees
Fahrenheit).
Humulene
Humulene is a terpene that is commonly found in hops.[11] It gives them and cannabis an earthy, spicy, or woody and is found in strains like White Widow or Headband. Humulene’s burning point is just past water’s boiling point at 106 degrees Celsius (228 degrees Fahrenheit).
Carene
Rounding out the list is carene, which has a sweet aroma similar to a cypress tree.[12] In terms of medical applications, there is evidence that this terpene may help with memory care, and could be useful for Alzheimer’s patients. It has a burning point of 170 degrees Celsius (338
degrees Fahrenheit).
