Lavender absolute (Lavandula angustifolia) is a dark-green liquid, which smells sweeter and less floral than the essential oil. It is a valued perfumery and aromatherapy material.
There are about 25-30 different species of lavender belonging to the Labiatae family. French lavender oil (Lavandula angustifolia) comes from Provence.
Lavender is a perennial, shrub-like plant that's part of the mint family. There are many variations of it, but lavender oil is perhaps the most versatile of them all. It's obtained from the flowering tops of the plants through steam distillation.
Rene Maurice Gattefosse, a early 20th century French chemist, discovered the soothing qualities of Lavender by once accidentally burning his arm and dunking his arm into lavender oil, which he thought was cold water. As a result, Maurice became extremely interested in the properties of essential oils and studied the topic more deeply. He is credited as the father of modern aromatherapy.
