http://en.wikipedia.org/wiki/Patchouli

Patchouli is a species of plant from the genus Pogostemon. It is a bushy herb of the mint family, with erect stems, reaching about 0.75 metre in height and bearing small, pale pink-white flowers. The heavy and strong scent of patchouli has been used for centuries in perfumes and, more recently, in incense, insect repellents, and alternative medicines.
