Cool off this summer with peppermint essential oil. Imagine this- after a hot, humid day, your skin is feeling icky-sticky with all that grime and sweat. You put in a few drops of cooling peppermint essential oil in your bath water. And then, you step in for a rejuvenating shower. Cut to you after shower, feeling relaxed and oh-so calm! Worth it in every sense. P.S. Add only a few drops of peppermint essential oil as it is quite potent. Do a patch test before using in its diluted form to ensure that it does not irritate your skin.
