It is super natural and can be found in most health food stores. I love the peppermint, but also check out the lavender for a soothing wash. Castile soap is very mild and good for all skin types. Its base is coconut, olive and jojoba oils, and any essential oil can be added to it. You can make your own castile soap by simply melting down castile granules or a bar of castile soap and adding your own oils to it.
Some suggestions are almond oil, apricot kernel oil, essential oils of orange, lemon, ginger.
In the top part of a double boiler, slowly melt the bar of castile soap until it turns into liquid. Add 1 teaspoon of essential oil to scent it and pour into a mold for a bar soap. To make a liquid castile soap, add 1 cup of water to the melted soap and then add 1 tablespoon of body oil and 2 teaspoons of essential oil for fragrance. Let cool, then pour into a bottle. Shop O2 .
