In a large bowl, mix to combine:
6 parts coarse sea salt
3 parts epsom salts, (to soothe tired muscles and reduce inflammation)
1 part baking soda, (to soften water and alleviate skin irritation).
Add a few drops of essential oils of choice, and combine.
To color, use drops of beet juice, blueberry juice, spinach or kale juice, lemon or other citrus juice, until you achieve the desired shade. If you intend to present the bath salts as gifts, be sure to store them in a stoppered and labeled container to keep out moisture.
