Persian chemist Ibn Sina (aka Avrenena) introduces the process of extracting oil from flowers by distillation. This is also the method most commonly used today. He conducted his first experiments with roses. Before he made his discovery, liquid perfumes were a mixture of oils and crushed herbs or petals of flowers, which was a combination of strong aroma. Pink water was finer and immediately gained popularity. Both untreated ingredients and distillation technology have a significant impact on western perfumery and the development of science, especially chemistry.
