Have you wondered about how to make essential oils?
Well, you can make your own essential oil at home, but the process isn't efficient or cost effective. It can take many pounds of plant material to make only a few drops of oil. You need a still, extractor, or distiller.
Note: Some Internet sources claim to tell you how to make essential oil but give instructions for an infused oil. An infused oil involves letting herbs soak in a vegetable oil. Infused oils are sometimes used for cooking and can also make a good aromatherapy carrier oil. However, an infused oil is not an essential oil and does not have its benefits.
How To Make Essential Oil With a Homemade Still
Here are some instructions using a homemade still that will extract some essential oil but is mostly useful for making aromatherapy hydrosol (scented water).
You need these supplies:
Pressure cooker (stainless steel*)
Vegetable steamer (stainless steel)
1-quart (or larger) glass jar (sanitized)
10 feet of 1/4-inch diameter copper** or food-grade vinyl plastic tubing
Dried or fresh herbs from which you want to extract essential oil
*Use stainless steel because aluminum may react with the essential oils.
**If you use copper tubing, tape off one end and fill the tube with fine sand to prevent it from kinking. Slowly wrap the tubing around a small bucket or something else with a cylindrical shape so that the tubing spirals in a way that fits into a 5-gallon bucket.
Follow these instructions:
Put the pressure cooker on a stove burner. Fill the cooker half-full of water.
Place a vegetable steamer inside the cooker, propping the streamer up, if needed, so that its bottom is above the water line.
Place the herbs you want to distill on the steamer.
the lid on the pressure cooker, but do not place the regulator vent on
top of the cooker. Instead, put a 10-foot length of food-grade tubing
over the outlet, using a hose clamp to ensure a tight fit.
Drop the other end of the tubing over the edge of the counter.
Place a 5-gallon bucket on a chair.
Coil the suspended end of the tubing inside the bucket so that the tubing wraps around at least four times.
Put enough cold water and ice in the bucket to cover the coiled tubing.
Drop the end of the tubing that is in the bucket over the edge toward the floor.
Place a sanitized small-mouth jar (at least 1-quart) on the floor.
Insert the end of the tubing into the jar, positioning the tubing so it falls straight into the jar.
Turn the burner on medium-high.
water will start to boil, creating steam inside the pressure cooker
that rises through the herbs and removes the essential oil, which flows
out of the cooker through the tubing.
When the steam inside the
tubing reaches the cold water in the bucket, the steam condenses and
converts back to water, literally dropping the essential oil.
Some oil will float on the surface of the water as it goes into the jar, but the product will be mostly hydrosol.
