What are Terpenes?

Terpenes (pronounced tur-peens),  are the building blocks of essential oils. They are aromatic organic hydrocarbons and are found in the essential oils of plants, fruits, vegetables, and more. For example, the smell of pine, pepper, roses, lemons, and hops are produced by powerful terpenes. Terpenes are extracted from plant essential oils by a process called molecular distillation. 

Terpenes have many properties and are very beneficial to the plants that produce them. For the plants that produce them terpenes are protective, they provide the plant with natural defense from bacteria, fungus, insects, and other environmental stresses. 

In humans, terpenes have been indicated to have several effects, they:

  • act on receptors and neurotransmitters
  • are prone to combine with or dissolve in lipids or fats
  • can act as serotonin uptake inhibitors (similar to antidepressants like Prozac)
  • can enhance norepinephrine activity (similar to tricyclic antidepressants)
  • can increase dopamine activity
  • can augment GABA and reduce neural spasticity
  • have some antimicrobial, antiviral, and antifungal properties
