Hello Hailey,
Could your daughter's problem possibly be magnesium deficiency? Maybe she had a positive reaction to the Epsom Salt in particuar, and it's not about "detoxing" but rather curing a deficiency? She might wish to try magnesium oil, sprayed onto the skin or as a bath. It is supposed to have many beneficial effects and helps quite quickly to restore your levels if you're deficient in magnesium.
Best wishes,
