Essential oils are highly concentrated plant essences obtained from flowers, leaves, fruits, wood, resins or roots, so these oils are aromas materialized in liquid form. Essential oils are transparent and colorless with their characteristic scent and taste. They are not greasy like carrier oils and evaporate at room temperature without leaving oily stains. Pleasant aromas create well‑being and support health. Just a few drops of a natural essential oil can fill a room with a refined fragrance, refresh the air and create a cozy, stimulating, sensual or balancing atmosphere.
