Lavender (Lavandula officinalis) was originally found only in the Mediterranean, but now blooms in many sunny locations around the world and is also very popular as a decorative garden shrub as it produces beautifully scented purple flower heads. The flowers come in a light blue to a deep purple color. These flowers are full of medicinally active compounds.The flowers are the main supplier of lavender oil, which is how the properties are extracted from the plant. The main active ingredients in lavender are 51% linalool and 35% linalyl acetate. Linalool is a terpene alcohol that is responsible for the strong floral scent of lavender.
