In a large bowl, mix the Epsom salts with the red food coloring. Stir thoroughly to ensure a uniform red hue. I like to do a second one without red food coloring, and then mix them in the jar at the end, or do layers.
Add the essential oils to the colored salts. Stir well to evenly distribute the invigorating candy cane scent.
Transfer the mixture into a plastic bag and seal it. Allow the salts to sit for several days, letting the fragrance infuse fully. Shake the bag gently each day to break up any clumps and refresh the blend.
Once ready, pour the bath salts into decorative jars or layer them with the uncolored salts for a striped candy cane effect.
To use, sprinkle the bath salts into warm or hot running bath water and enjoy a festive, relaxing soak.
