These multi-purpose 4 bag food grade extraction kits can be used for making aroma therapy oils, cooking oils, and other natural products from plant matter. Simply insert each bag into the other, and place into a clean, empty bucket. Fold the top portion of the bags over the top of the bucket to create a large opening and add cold water. Once the bucket is about half full add the plant material evenly, then slowly add ice to the plant and water mixture. Once the ice has covered the mixture, stir for at least 20 minutes. For minimized labor, you may choose to use a hand mixer or mixing bit with drill. Remove each bag and let the water drain thoroughly.
