Patchouli Oil.

It is light yellow to dark brown in color and is a thick oil. Patchouli oil is extracted from Pogostemon cablin (also known as Pogostemon patchouli) of the Labiatae family and is also known as patchouly and puchaput. Patchouli oil is extracted from the young leaves which are dried and fermented prior to steam distillation and yields 2 - 3 %. This oil improves with age to have a fuller, more well rounded odor.
