1 cup of Epsom salt 1/2 cup of baking soda A mason jar or airtight container Peppermint essential oils Eucalyptus Radiata essential oils Optional: green food coloring Mix the baking soda and Epsom salt together. Once it’s mixed, add food coloring if you’re going to complete that step. All this does is make it look colorful, otherwise it will be white. Then add 5 drops of peppermint oil and 10 drops of eucalyptus oil. Mix it all up & place into storage jar.
