Soaking in a bath with Epsom salts can help relax your muscles, reduce swelling and draw out toxins. Baking soda helps sooth your skin. Vanilla is a very calming scent, that’s why it was included into this bath salt craft. You’ll need 1 cup Epsom salt, 1 1/2 tablespoon baking soda, vanilla fragrance or essential oil, brown powder food coloring. Place salt and soda into a dish and stir well. Add fragrance oil until it is strong enough to suit your preference. Stir well and add brown colored powder food coloring if desired. Put them into some jar to store and enjoy!
