How to make purification oil?

If you’re referring to essential oils used for purification (such as air purification), purification oil can be made by blending essential oils with purifying properties. For example, combining eucalyptus, tea tree, lemon, and peppermint oils creates a natural purifying blend. To make this blend, mix a few drops of each oil in a carrier oil (like coconut or almond oil) or in a diffuser for air purification.
