While I don't make any medical claims about my products, I do make a point to use high quality essential oils in them. In this flu and cold season, washing hands frequently is the best way to keep yourself healthy. Any soap is a good choice, but I like to recommend my handmade soaps because they are moisturizing rather than drying and that's important when you wash your hands a lot. I use my plague ban oils in both my soap and roller bottles you can apply to your skin.
