pogostemon cablin
CAS 8014-09-3; 84238-39-1
EC 282-493-4
Steam distilled from the dried patchouli leaf . "dark" usually reflects its extraction in iron drums, which imparts a darker hue to the oil.
Base note. Earthy, sweet ( particularly for those rebellious, or ridiculously hopeful, 60's children) penetrating and very persistent.
