Epsom salts have been used for centuries as a natural remedy for a variety of health and wellness needs. Known scientifically as magnesium sulfate (MgSO₄·7H₂O), they are widely appreciated for their ability to relieve sore muscles, reduce stress, and improve overall well-being. In this blog, we’ll explore their evidence-based uses in bath bombs, skincare, gardening, and household cleaning.

What Are Epsom Salts?

Epsom salts are a naturally occurring mineral compound of magnesium, sulfur, and oxygen. When dissolved in warm water, they dissociate into magnesium ions (Mg²⁺) and sulfate ions (SO₄²⁻), which may be absorbed transdermally to support cellular function.

Benefits and Uses of Epsom Salts

1. Relaxing Baths

Add 250–500 g (1–2 cups) to a standard bath (37–39°C). Benefits include:

• Muscle relaxation via magnesium uptake
• Stress reduction through parasympathetic activation
• Improved circulation and reduced inflammation
• Enhanced sleep quality (magnesium supports GABA function)

2. Epsom Salts in Bath Bombs

A key ingredient in fizzy, therapeutic bath bombs. When combined with:

• Sodium bicarbonate + citric acid → CO₂ fizz
• Essential oils + carrier oils → aromatherapy
• Epsom salts → magnesium delivery

Result: A muscle-soothing, spa-like experience.

• Supports lactate clearance

5. Skincare & Exfoliation

Mix 1 part Epsom salts + 1 part carrier oil for a gentle scrub. Removes keratin buildup and softens skin.

6. Foot Soaks for Pain & Swelling

Dissolve 100 g in 4 L warm water. Soak 15–20 minutes to reduce edema and odour.

7. Gardening & Plant Care

• Foliar spray: 10 g/L water — boosts chlorophyll
• Soil amendment: 50 g/m² for magnesium-deficient plants
• Enhances bloom size in roses, tomatoes, peppers

8. Household Cleaning

Mix with dish soap for a non-toxic scrub. Removes grout, tile residue, and burnt-on food.
