Hemp is far more than a sustainable crop used for textiles, food, and industrial products. Behind hemp’s growing popularity lies a fascinating world of naturally occurring compounds that contribute to the plant’s unique characteristics. Among the most important of these compounds are cannabinoids and terpenes.
These naturally occurring substances have become a major focus of scientific research and consumer interest. Whether you’re exploring hemp flower, hemp extracts, or other hemp-derived products, understanding cannabinoids and terpenes can help you better appreciate what makes hemp such a remarkable plant.
In this guide, we’ll break down the science behind hemp, explain how cannabinoids and terpenes work, and explore why they play such an important role in the hemp industry.
What Is Hemp?
Hemp is a variety of the Cannabis sativa plant that contains no more than 0.3% Delta-9 THC on a dry-weight basis under U.S. federal law.
Unlike marijuana, hemp is primarily cultivated for:
-
Hemp fiber
-
Hemp seeds
-
Hemp oil
-
Industrial applications
-
Hemp-derived cannabinoids
-
Hemp flower
One of the reasons hemp has attracted so much attention is its rich chemical profile. Researchers have identified hundreds of naturally occurring compounds within the hemp plant, including cannabinoids, terpenes, flavonoids, and other plant constituents.
What Are Cannabinoids?
Cannabinoids are naturally occurring compounds found in cannabis plants, including hemp.
These compounds interact with the body’s endocannabinoid system (ECS), a complex network involved in regulating various physiological processes.
Scientists have identified more than 100 cannabinoids in cannabis plants, although only a handful are found in significant concentrations.
Why Do Hemp Plants Produce Cannabinoids?
Cannabinoids serve several purposes for the plant itself.
Researchers believe cannabinoids may help:
-
Protect against environmental stress
-
Defend against pests
-
Support plant survival
-
Regulate biological functions within the plant
While much remains to be discovered, cannabinoids are considered one of hemp’s most valuable natural components.
Understanding the Endocannabinoid System
To understand cannabinoids, it’s helpful to understand the endocannabinoid system.
The ECS is a naturally occurring biological system found throughout the human body.
It consists of:
-
Endocannabinoids (naturally produced compounds)
-
Receptors
-
Enzymes
The two most commonly discussed receptors are:
CB1 Receptors
Primarily found in:
-
Brain
-
Central nervous system
CB2 Receptors
Commonly associated with:
-
Immune system
-
Peripheral tissues
Plant-derived cannabinoids can interact with this system in various ways, making cannabinoids a major area of ongoing scientific study.
Major Cannabinoids Found in Hemp
CBD (Cannabidiol)
CBD is the most abundant cannabinoid found in many hemp varieties. CBD has become one of the most recognized hemp-derived compounds in the world, leading to a growing market for oils, gummies, tinctures, capsules, and other wellness products available through retailers such as Alt Super Store.
Common sources include:
-
Hemp flower
-
CBD oils
-
Hemp gummies
-
Capsules
-
Topicals
CBD is non-intoxicating and does not produce the “high” associated with THC.
CBG (Cannabigerol)
Often referred to as the “mother cannabinoid,” CBG serves as a precursor to several other cannabinoids during plant development.
Many emerging hemp products now feature CBG-rich formulations.
CBC (Cannabichromene)
CBC is another naturally occurring cannabinoid found in hemp.
Although present in smaller concentrations than CBD, it continues to attract scientific interest.
CBDV (Cannabidivarin)
CBDV is a minor cannabinoid found in certain hemp varieties.
Researchers continue to study its unique characteristics and potential applications.
THC (Tetrahydrocannabinol)
THC is the cannabinoid most commonly associated with cannabis.
Federal hemp regulations require hemp to contain no more than 0.3% Delta-9 THC on a dry-weight basis.
Because hemp contains only trace amounts of THC, it differs significantly from marijuana.
What Are Terpenes?
While cannabinoids often receive the most attention, terpenes are equally fascinating.
Terpenes are aromatic compounds naturally produced by many plants, including:
-
Hemp
-
Pine trees
-
Citrus fruits
-
Lavender
-
Herbs
They are responsible for the distinctive aromas and flavors associated with different hemp varieties.
Why Do Hemp Plants Produce Terpenes?
Terpenes play several important roles in nature.
Scientists believe they may help:
-
Attract beneficial insects
-
Repel pests
-
Protect against environmental stress
-
Support plant survival
These compounds contribute significantly to the sensory experience of hemp products.
Common Terpenes Found in Hemp
Myrcene
Myrcene is one of the most abundant terpenes found in cannabis plants.
Its aroma is often described as:
-
Earthy
-
Herbal
-
Musky
Limonene
Limonene is commonly found in citrus fruits.
Its scent is often characterized as:
-
Bright
-
Citrusy
-
Refreshing
Pinene
Pinene is also found in pine trees.
Its aroma is:
-
Fresh
-
Pine-like
-
Woody
Caryophyllene
Caryophyllene is known for its:
-
Peppery aroma
-
Spicy characteristics
It is commonly found in black pepper, cloves, and hemp.
Linalool
Linalool is frequently associated with lavender.
Its scent profile includes:
-
Floral notes
-
Sweet aromas
-
Herbal undertones
How Cannabinoids and Terpenes Work Together
One of the most discussed concepts in hemp science is the relationship between cannabinoids and terpenes.
Researchers have proposed that these compounds may interact in complex ways within the plant’s overall chemical profile.
This concept is often referred to as the entourage effect.
What Is the Entourage Effect?
The entourage effect is a theory suggesting that multiple compounds within the hemp plant may interact together rather than functioning independently.
These compounds can include:
-
Cannabinoids
-
Terpenes
-
Flavonoids
-
Other naturally occurring plant constituents
Research in this area continues to evolve, and scientists are actively studying these interactions.
What Are Flavonoids?
In addition to cannabinoids and terpenes, hemp contains flavonoids.
Flavonoids are plant compounds responsible for:
-
Color
-
Pigmentation
-
Certain protective functions
They are found in many fruits, vegetables, and flowering plants.
Although less discussed than cannabinoids and terpenes, flavonoids contribute to hemp’s overall chemical complexity.
Why Cannabinoids and Terpenes Matter
Understanding cannabinoids and terpenes can help consumers better understand hemp products.
These compounds influence:
Aroma
Terpenes contribute to hemp’s unique scent profiles.
Flavor
Different terpene combinations affect flavor characteristics.
Plant Diversity
Variations in cannabinoid and terpene profiles help distinguish different hemp cultivars.
Product Selection
Consumers often compare cannabinoid and terpene profiles when choosing hemp products.
