Terpenes are naturally occurring compounds found in many plants, including cannabis. They are responsible for the distinctive aromas and flavors in different strains and are also present in many other plants like pine trees, citrus fruits, and herbs such as black pepper and tea tree oil.
In cannabis strains, terpenes contribute to the plant's unique aromas and flavors. This guide takes a scientific approach to understanding common terpenes in the cannabis plant and their effects.
A Scientific Perspective on Terpenes
Terpenes are a diverse class of compounds built from repeating units of isoprene—a basic five-carbon building block. The number of these units defines the class of the terpene:
Monoterpenes: Composed of two isoprene units. These are smaller molecules, highly volatile (e.g., limonene, borneol, terpineol).
Sesquiterpenes: Made up of three isoprene units. These molecules are less volatile, more stable, and can provide longer-lasting effects (e.g., caryophyllene).
Diterpenes and triterpenes: Contain four or more isoprene units and are even larger and less volatile. They occur less frequently in cannabis but are significant in other plant compounds.
Smaller terpenes (like monoterpenes) are more volatile and soluble in essential oils and fragrant oils, making them effective in applications like aromatherapy and flavoring.
On the other hand, larger terpenes (like sesquiterpenes) are less volatile and more stable, which can potentially provide longer-lasting effects. This stability is beneficial in formulations where extended activity is desired, such as topical anti-inflammatory agents.

How Terpenes Influence the Cannabis Experience
As cannabis brands are collaborating across borders, they are finding innovative ways to highlight the benefits of different terpenes. In cannabis, terpenes play a significant role by engaging with the body's systems, particularly the endocannabinoid system (ECS).
The ECS is a complex cell-signaling network that helps regulate functions like mood, sleep, and immune response. While terpenes don't directly bind to cannabinoid receptors like THC or CBD, they may influence how these cannabinoids interact with the ECS.
The concept known as the "entourage effect" describes how terpenes and other compounds in cannabis work together to produce a combined effect that might differ from the effects of each compound alone. For instance, certain terpenes found in cannabis, such as myrcene or pinene, may interact with THC to enhance its calming properties.

Applications of Terpenes Beyond Cannabis
Terpenes are used in a wide range of industries beyond cannabis. Their distinctive aromas and potential therapeutic properties make them valuable in several applications, such as:
Perfumes and Fragrant Oils
Terpenes are essential in the fragrance industry, where they help create unique aromas and distinctive scents. For instance, compounds like limonene from citrus fruits and linalool from lavender are common in fragrant oils and perfumes. These terpenes add fresh, floral, or spicy notes to different products to enhance their appeal.
Cleaning Products
Many terpenes have antibacterial properties and are found in cleaning products. For instance, eucalyptol and terpinolene are used for their potential to fight bacterial infections and provide a refreshing scent. Tea tree oil, containing terpenes like terpinene, is often added to cleaning agents and skin care products for its anti-inflammatory and antimicrobial effects.
Food and Beverage Industry
Terpenes are vital in flavor development in the food and beverage sector. For example, limonene, with its citrus notes, enhances the taste and aroma of many beverages and foods. Similar terpenes help create authentic flavors and are crucial in developing natural food products and flavorings.
Health and Wellness
Terpenes are widely used in the health and wellness industry, particularly in aromatherapy and personal care products. Compounds like linalool are known for their calming and soothing effects and are often used in essential oils and relaxation products. Eucalyptol is used in topical applications for its potential anti-inflammatory and respiratory benefits.
Pet Food and Animal Care
The pet food and animal care industry also utilizes terpenes for their therapeutic properties. Terpenes found in ingredients like citrus fruits and herbs can enhance flavor and provide potential health benefits for animals. Compounds like humulene and caryophyllene are added to pet care products for their anti-inflammatory effects.
Terpene Quality: What to Look For
The quality of terpenes depends on several critical factors. Knowing how to identify high-quality terpenes can help ensure that you choose products that offer the best properties and benefits.
Source of Terpenes
The source of terpenes is a key determinant of their quality. High-quality terpenes should come from natural, sustainable sources. The plants from which terpenes are derived must be free from pesticides and other harmful chemicals. Terpenes sourced from organically grown plants are generally considered superior.
