Combine all ingredients in a small bowl and stir well.
Apply the mixture to your skin and massage in a gentle, circular motion to remove flakes. Rinse well. Store any remaining scrub in the refrigerator for up to a month.
Notes
If you have sensitive skin, grind your herbal ingredients into a fine powder with a mortar and pestle or a coffee grinder. Otherwise, toss them in whole and be gentle around any irritated areas.
