1. Distillation is the most commonly used method for extracting peppermint essential oil. Put the plant mint into a container and heat it from below to generate steam, allowing the essential oil of the plant to follow the steam. After the water vapor containing the essential oil is collected and cooled by the tube, the steam will be cooled into a liquid, and then according to the specific gravity and density of the water and the essential oil. The difference is separated, and the remaining water is pure dew, and most of the essential oils are extracted by this method.
