Terpinolene: Found in parsnips, parsley, lilacs, nutmeg, cumin and apples, terpinolene gives a piney, floral, herbaceous aroma with a hint of citrus. It smells fresh, which is the reason it's often used in soaps and perfumes. It is the least-common terpene. Commonly found in Dutch Treat and Haze genetics, terpinolene is believed to have uplifting effects. Studies have shown it may also have antibacterial and anti-fungal qualities and other research suggests it repels pests such as mosquitoes and weevils.
