Epsom salt (magnesium sulfate) offers benefits like muscle pain relief, stress reduction, and skin exfoliation by releasing magnesium and sulfate when dissolved in water, absorbed through skin or ingested (as a laxative). Key uses include soothing sore muscles in baths/foot soaks, enhancing sleep, detoxifying, improving skin/hair health (like dandruff), and even as a garden fertilizer for plant growth.
