Benefits Of Terpenes And Where To Get Them

Benefits Of Terpenes

Have you ever wondered why there’s a distinct aroma in some herbs, fruits, and leaves? The aromatic factors are controlled by terpenes. It is a natural and organic compound which is found in plants and possesses enormous potential in health management.

Today we are going to learn about terpenes, where you can find it and their roles and how association with cannabis.

What Is Terpenes?

Terpene[1] is an organic hydrocarbon compound which is volatile in nature. It is produced in the epidermal cells i.e. glandular trichomes[2], in the plants. It is found in the essential oils and is known to possess an aroma.

Though the humans have always been crazy for the natural aroma extraction from the ancient times, the basic responsibility of the terpenes is to protect the plants from insects, herbivores, bacteria, and fungi.

There are hundreds of different types of terpenes, and cannabis alone is a rich source of nearly 200 terpenes. Some terpenes have strong smelling properties, while some are mild and pleasant to our sensory organs.

Plant-based organic essential oils extracted from the leaves, flowers, fruits, barks, and seeds contain terpenes. Synthetic terpenes are produced in the labs under controlled atmosphere.

Terpenes easily evaporate and are susceptible to heat. During the daytime, the terpenes evaporate from the tiny glandular trichomes. That is why you can smell the trees and flowers in summer or in the morning from a distance.

The conifers are particularly considered to be among the rich sources of terpenes. Although these are mainly plant-derived products, some insects and butterflies are known to produce terpenes.

There is a widely accepted myth that terpenes and terpenoids are the same. On the contrary to popular belief, terpenes are isoprenes (hydrocarbons) which are made of hydrogen and carbons, whereas, terpenoids are the produce of oxidization.

Extraction of essential oil or terpenes in the lab is done by applying several methods, but the basic procedure is by boiling and distillation of the plant substances.

Extracted terpenes are used for medicinal properties in cosmetics, drugs, and toiletries. It also has healing properties for which it is widely used in aromatherapy.

Where Do You Get Terpenes?

Get Terpenes

All aromatic plant, barks, resins, leaves, and fruits contain volatile terpenes. The essential oils contain terpenes, however, some of the properties can be destroyed in the processing if the extraction method was faulty. If you are using fresh and organic herbs and plants, the benefits are likely to increase. Peppermint, spearmint, cedarwood, sandalwood, Eucalyptus, cinnamon, cardamom, oregano, thyme, tea tree, cannabis, citrus fruits such as oranges, lemon and lime are only a few names of the essential oil sources.

Each essential oil type is attributed to special terpene. While some common terpenes are found in multiple sources, there are other types which are limited to particular species. The fruits and herbs that are rich in terpenes are:

  • Rosemary: Rosemary[3] contains a high amount of terpinolene. Rosemary essential oil has great medicinal and healing quality, it is even used for strengthening cognitive development, writes naturopathic physician Jessica Patella[4].
  • Eucalyptus: Eucalyptus[5] essential oil is a rich source of various terpenes, among which Eucalyptol or cineole is prime. The use of eucalyptus essential oil is seen in naturopathy. It is anti-inflammatory and relieves pain, has antioxidant and antibacterial properties.

  • Citrus fruits: lemon, lime, sweet oranges and all other citrus fruits are rich in limonene. It is used in perfumes, beauty products, and aromatherapy.
  • Camphor: The strong pungent odor in camphor is due to camphene[11], a special terpene. It has anti-fungal and antibacterial properties and widely popular in the cosmetic industry, taste enhancer in the food industry and in pesticides.
  • Sweet Basil: Rich in myrcene[12] terpene, sweet basil is used for its antibiotic advantages.
  • Pine: Monoterpenoid pinene is abundant in pine wood and fir. There are two types of pinene found in pine, which are known as alpha-pinene and beta-pinene. It is useful for mental health and asthma patients.

Terpenes In Cannabis & Their Roles

Terpenes In Cannabis

Cannabis refers to the group of plants comprise of marijuana or Cannabis sativa I and hemp or Cannabis sativa L[14]. Cannabis plants are the best sources of terpenes because it alone houses more than 120 terpenes which are rare in nature.

Essential oils extracted from cannabis are used in medical treatment and drugs, beauty products, and perfumery. Rich in organic compounds, these terpenes are most valuable and extremely beneficial for healing and prevention of diseases.

You can buy different types of essential oils but cannabis oil alone provides nearly all major terpenes. It is all in one product which has been in use since ancient times. Terpenes are found in the resins from glandular trichomes in female inflorescences in Cannabis sativa.

Terpenes are the building blocks of cannabinoids in cannabis plants. The therapeutic pharmacological benefits determine synergizing effects in cannabis terpenes which is most commonly referred to as “entourage effect[15]”.

THC (tetrahydrocannabinol) compound in cannabis has been the center of attraction to many research scholars, geneticists, naturalists, biologists and in the field of organic chemistry, while other terpenes and cannabinoids have been overlooked.

In the more recent years, some researchers have shown interest in extraction, preservation and using the cannabis essential oil to study the effects of terpenes, flavonoids, and cannabinoids on the humans. Together all these ingredients act as a natural defense against bacterial infection, skin diseases and improve mental and internal health.

You will often find these terms when we will discuss the terpenoids in cannabis- monoprenes which are single isoprenes, sesquiterpenes are three linked isoprene units and diterpenes are four units.

Depending upon developmental, environmental and genetic factors the composition and concentrations of terpenes in cannabis vary greatly.

In some cases, one may still be able to predict the ratio of cannabinoids in different strains of cannabis but the concentration of terpenes remains unpredictable.

The major terpenes found in cannabis are linalool, limonene, myrcene, eucalyptol, caryophyllene, pinene, terpinene, guaiol, humulene, ocimene, valencene, phytol, and nerolidol.

1.Limonene

The refreshing and cool scent of citrus fruits is due to limonene[16]. The smell instantly hits the nervous systems and almost brings us back to life after a tiring day at work. The use of limonene can be seen in a variety of products.

The ingredient is widely popular among the aromatherapists as well. Use of limonene in the food industry as additives and flavor enhancer is quite popular. The use of limonene to control gastroesophageal reflux is well established.

2.Beta-Myrcene

It is also most common terpene found in cannabis. The herbal aroma of beta-myrcene[17] has hundreds of benefits. Other than cannabis, you can also find it in bay leaf, lemongrass, eucalyptus, and hops.

Some cannabis strains contain nearly 60% beta myrcene monoterpene out of the total oil extracted. Other than perfumery, it is also used in medicine, drugs, naturopathy, and aromatherapy.

It is antibiotic, analgesic, anti-inflammatory, and anti-depressant. It has calming effects on the mind and is used for relaxing the brains. It lowers the resistance power of the brain and allows the organic chemicals to react with the blood quickly. Therefore, it may also expand the absorption of THC in blood.

Pinene is abundant in the coniferous plants. It is found in pine trees and also in cannabis strains. The bicyclic monoterpenoid is made of alpha-pinene (a-pinene) and beta-pinene (ß-pinene), the first one being most commonly found in nature.

Having antibiotic properties, it helps to kill bacteria and reduces inflammation. Alpha-pinene also increases cognitive function among the patients.

Several types of research have been carried out to explain the medicinal benefits of a-pinene and it is proved that it is a natural bronchodilator which helps clear congestion and sinusitis. In order to relax the mind and to improve concentration the use of pinene is remarkable. Weiqiang Chen[18] and colleagues published a research paper which mentions that a-pinene has anti-tumor effects.

4.Linalool

It is one of the major terpenes found in cannabis plants. The sweet lavender scents notify the presence of linalool[19]. Other than lavender, you can also find it in cannabis. Other sources are mint, coriander leaves, basil, cinnamon and citrus fruits.

List Of Hemp Cannabinoids And Terpenes

Unlike marijuana, hemp contains a lower concentration of terpenes. However, hemp essential oil is still rich in several important terpenes. The most common hemp terpenes[30] are myrcene, d-limonene, linalool, alpha-pinene, humulene, eucalyptol, and nerolidol.

The use of hemp and hemp seed oil is practiced to prevent autoimmune diseases, fight skin problems, rheumatoid arthritis, anxiety, and sleeplessness.

Terpenes In Hemp

We have already learned about all major terpenes in the previous section, so let’s find out about nerolidol and phytol.
