How can I safely mix essential oils with water for use in aromatherapy or other applications?

To safely mix essential oils with water for aromatherapy or other applications, start by choosing a glass or PET plastic container. Add a few drops of essential oil to the water and shake well before each use. Be cautious with the amount of essential oil used, as they are highly concentrated. It's important to do a patch test on your skin before using the mixture extensively. Remember to store the mixture in a cool, dark place away from direct sunlight.
