Patchouli, which many people associate inextricably with the hippie movement, in fact boasts a long history as a perfume fixative and textile preservative. Because the fresh leaves of the Pogostemon patchouli plant yield a somewhat displeasing sharp scent when used in fragrance formulas, perfumers generally distill dried leaves in order to make patchouli essential oil. Patchouli grows best as a tender perennial. In warmer climates the shrubby herb stays in the ground year-found, but in colder zones it’s best grown in pots and brought indoors for the winter.
Things You'll Need
- Patchouli plants
- Pruning shears
- Stockpot and lid
- Small grill or canning rack
- Brick or casserole dish
- Heat-proof bowl
- Ice cubes
- Glass or ceramic jar with lid
- Small glass vial or bottle with cork or stopper
Harvest the plant in mid-morning, after the dew dries. Prune several patchouli plants by cutting them down almost to the base, leaving several inches to regrow.
Hang the plants, in bunches, in a shady, dry area for several weeks.
Separate the leaves from the stems and reserve the stems for another use, such as adding fragrance to a fire.
Place a heat-proof grill or canning rack at the bottom of a large stockpot.
Put a clean brick or overturned casserole dish over the grill and rest a heat-proof bowl, face-up, on top of the brick.
Set the dried patchouli leaves on top of the grill, in a circular pattern around the brick and bowl. The leaves should reach about halfway up the outside of the bowl.
Pour distilled water over the leaves, completely saturating them.
Turn the burner on high. When the water begins to boil, lower the heat to simmer.
Cover the stockpot with its lid inverted, so that the handle hangs upside down inside the pot, centered over the bowl.
Place ice cubes on the center of the pot’s lid. This action causes condensation within the pot. The bowl collects the distilled patchouli water essence.
Simmer the patchouli leaves and water for several hours, adding fresh distilled water as needed. Make sure the distilled water goes only over the leaves, not in the collected liquid in the bowl.
Replace the ice cubes on the outside of the pot’s lid as needed.
Allow the pot and its contents to cool.
Pour the collected patchouli essence from the bowl into a glass or ceramic jar. This hydrosol, useful in its current form as a perfume or bath ingredient, can be further separated into essential oil and a less-potent hydrosol.
Place the covered jar in the freezer and remove once the liquid has frozen.
Pour off the unfrozen liquid floating on top of the frozen matter. This is your patchouli essential oil.
Store the patchouli essential oil in a small dark vial or bottle.
Check the oil every month or so by placing it on a wood scarf or adding it to jojoba oil and dabbing on the skin. More than many other oils, patchouli oil needs a significant aging process in order to achieve the desired mellowness.
