Terpenes are all around us. Terpene is a word used to describe the unique phyto-chemicals derived from fruits and plants. Terpenes are mostly responsible for the aroma, flavor, and fragrance of fruits and plants. Here at Ala Rassi, we use terpenes extracted from a variety of fruits. So in short, terpenes are responsible for the potent, herbaceous and sweet scents of botanicals and plants.
