Attar, also known as ittar, is an essential oil derived from botanical or other natural sources. Most commonly these oils are extracted via hydrodistillation or steam distillation. The Persian physician Ibn Sinawas the first to derive the attar of flowers from distillation.[1] Attar can also be expressed by chemical means but generally natural perfumes which qualify as attars are distilled with water. The oils are generally distilled into a wood base such as sandalwood and then aged. The aging period can last from one to ten years depending on the botanicals used and the results desired.
