1/4 cup aluminum free baking soda
1/4 cup organic cornstarch (or arrowroot powder)
5-6 tablespoons coconut oil
5-10 drops tea tree oil
Mix all ingredients together and press into an old deodorant container. To use, let it rest against your skin for a couple seconds to soften the coconut oil, do one slow swipe under each arm and use the palm of your hand to spread it around.
