WHAT ARE TERPENES – OVERVIEW

Terpenes are the organic compounds that give flavors and aromas to all kinds of plants. They are the fragrant oils found in plants that produce a unique smell and taste. These are more common in coniferous varieties, as well as the citrus plants. The chemical compounds they secrete give fruits, vegetables, herbs, and flowers their distinctive scents. In general, their function is to promote the well-being of the plant. For example, by attracting pollinators or protecting it from pathogens and predators, but they also possess biological properties that are believed to support human health. Terpenes are also a major component of the essential oils, which are the crux of aromatherapy. While terpenes are increasingly trending today, they do have a history that spans civilizations. Scientists have been studying terpenes for ages in order to understand their properties and to figure out ways to implement their aromas in different applications. Terpenes can be found in food and beverage flavorings and also in medicines and disinfectants, serving as natural cleaners. Of late, terpenes are rapidly gaining popularity in the cannabis industry for their variety of flavors on offer and also for their reputed entourage effects. Regardless of their applications, terpenes are a fascinating subject that you may already be appreciating without prior awareness.

HISTORY OF TERPENES

As mentioned earlier, while terpenes are in demand today, especially in the CBD and cannabis space, they have been around for a very long time. Throughout history, terpene applications have been identified with Egyptians, Babylonians, Romans, Greeks, Hebrews, and even the Chinese. The common ground among all these cultures is their use of essential oils and terpene elements medicinally. Their usage can be traced back to Ancient Egypt, where they were used as fragrances in religious ceremonies. It is also believed that the chemists in that era, used to mix the terpenes into blends for creating fragrances and also for feminine hygiene purposes.

There are traces of terpenes in the 11th century, with the introduction of camphor in Eastern Europe by the Arabs, primarily for the treatment of pain and illness. Its strong aromatic properties were also used for fumigation during the Black Death Era. Camphor was known to be mixed into rosewater and sprinkled onto the dead, before burying them. Later, in the 17th century, a German chemist named Otto Wallach identified the structure of many terpenes. The rich aromas of the variety of spices found in Indian food are because of terpenes. This proves that no matter where in the world you are, terpenes are omnipresent, be it in vegetables, fruits, herbs or spices.

WHAT ARE THE BENEFITS OF TERPENES

Different terpenes are known to provide different benefits both to the mind and body. Some may offer cleansing and cosmetic benefits while other can alleviate pain. Similarly, some can provide stress relief while others can improve appetite as well. Basically, think of terpenes as natural compounds you may have never heard of, that can boost your health.

Similar to the way aromatherapy works, inhaling the aroma of certain terpenes are known to boost the emotional well-being. For instance, the floral scent of linalool terpene, found in lavender, has a soothing effect that helps you sleep better. Likewise, another terpene like limonene, which is found in peppermint and citrus fruits can elevate your mood.

Terpenes have a wide range of health benefits and have been studied for numerous medical applications. Terpenes are known to be studied for their antiviral characteristics. It is also believed that certain terpenes have shown potential for treating cancer and diabetes. For cannabis users, terpenes are known to provide a better experience without the usual side effects. Apart from these benefits, terpenes are known for their anti-inflammatory, analgesic, anti-bacterial, and anti-depressant properties.

Terpenes tend to be immediately associated with marijuana. This is for a very good reason as hundreds of terpene compounds have been found in cannabis. They have become a popular part of the marijuana conversation, as the legal usage of cannabis has been on the rise lately. Today, marijuana growers seek to prioritize terpenes in their strains to add a variety of aromas and flavors. This helps, both the marketing and taste of their product. As marijuana is still illegal on a federal level in United States, researchers find it hard to study the terpene effects in marijuana. The “entourage effect,” as it is generally known, refers to terpenes reacting synergistically with cannabinoid compounds like THC in the endocannabinoid system in order to affect the body and mind.

Along with the mind, terpenes are also known to have physical effects. But, to what extent is that effect depends on the specific type of terpene. Overall, terpenes may be able to have the following physical effects like:

• Anti-inflammatory properties
• Anti-bacterial properties
• Pain relief
• Muscle spasm relief
• Antifungal properties

GUIDE TO COMMON TERPENES

Terpenes are simple hydrocarbons, while terpenoids are a modified class of terpenes with different functional groups and oxidized methyl groups moved or removed at various positions. Terpenoids are divided into monoterpenes, sesquiterpenes, diterpenes, sesterpenes, and triterpenes depending on their carbon units.

Most of the terpenoids with the variation in their structures are biologically active and are known to be used worldwide for the treatment of many diseases. Let’s look at some of the key details of the most common terpenes, their aromatic profiles, which oils are known to contain them, and the reputed benefits they confer.

CONTRAINDICATIONS FOR ESSENTIAL OILS

As with all NDA products, the essential oils mentioned in this article are for external use only. Due to the highly concentrated nature of essential oils, they must be diluted with a carrier oil prior to topical use. We recommend consulting a medical practitioner prior to using any essential oil for therapeutic purposes, particularly for those who are pregnant, nursing, or who have a pre-existing medical condition.

Possible side effects from the use of essential oils include irritation or allergic reaction from topical use. To reduce the risk of adverse reaction, a skin patch test should be performed before prior to using the oil. The test can be performed by diluting 1 drop of essential oil in 4 drops of carrier oil and applying a dime-sized amount of the blend to a small area of skin that is not known to be sensitive. In the event of an adverse reaction, discontinue the use of the product and see a medical healthcare professional for appropriate remedial action. Certain essential oils may pose additional risks depending on individual health and medical history. To prevent side effects, it is best to consult with a physician prior to use.

Essential oils must not be used near the eyes, inner nose, ears, or on any areas of the skin that are known to be sensitive. They should always be stored in an area that is inaccessible to children, particularly those under the age of 7.
