Terpenes are a class of volatile hydrocarbon compounds produced by the cannabis plant as well as most other plants. Terpenes readily evaporate at room temperature, and our noses are highly sensitive to them.
Terpenes are recognized as safe for human consumption by the Food and Drug Association and are used in a wide variety of food and cosmetic products.
In nature, terpenes act as both a repellent for pests and as attractants for pollinators and seed spreaders. In cannabis, terpenes are produced in highest concentrations in the plant’s female flowers.
Although terpene molecules are all very similar, each has its own unique scent and flavor. Various combinations of terpenes are responsible for the distinct aromas of cannabis strains.
Terpenes can also have powerful effects on our bodies. In fact, terpenes have been utilized by humans for millennia in a healing modality known as aromatherapy. For example, the scent of citrus is produced primarily by a combination of limonene and pinene, both of which are thought to elevate mood.
Below are some of the most common terpenes along with their reported benefits:
