Eczema sufferers are always looking for a magical cure. Do some research with the help of Google and you’ll find many options. Healing crystals and tea tree oil are just a couple of examples. 

One treatment that comes up, again and again, is Epsom Salts. The information you find in this post will help you decide whether Epsom salt will work for you. You’ll also learn how best to use Epsom salt baths. 

Does Epsom Salt Help Eczema?

Does Epsom Salt Help Eczema?

In order to understand whether Epsom salt baths can help your eczema, let’s start by looking at what Epsom salt really is. 

A more technical term for Epsom salt is “hydrated salt”. Basically, Epsom salts are inorganic salt that combines sulfate and magnesium to make easily absorbable magnesium sulfate.


Magnesium is easily absorbed by the skin and helps reduce inflammation caused by eczema and similar skin conditions. It is a vital component in many skin care products because it helps to replenish skin while also moisturizing and soothing your skin. Magnesium supplements have been shown to reduce chronic inflammation

One of the many skincare benefits of magnesium is that it can help reduce inflammation caused by conditions that lead to dry and itchy skin, such as eczema. Magnesium has the ability to influence immunological responses to antigen issues. It has a skin barrier function and stops the immune system from producing pro-inflammatory factors that cause inflammation. 

Magnesium can also help decrease anxiety and stress, which can trigger eczema flare-ups. It can also lower blood toxicity because it functions as an alkalinizing agent.  In addition, magnesium helps muscle and nerve function. 


Sulfur is a mineral found within the Earth’s crust, usually near volcanic vents. There are no studies that prove sulfur is an effective treatment for eczema. A 2017 animal study found that mineral-rich spring water reduced eczema-like inflammation in mice. However, there have been no specific human studies.  

Sulfur appears to be keratolytic and antimicrobial. This means it can hydrate and soften dry, hard skin. It is also thought to have anti-inflammatory properties and could reduce itching.

Epsom salt, or magnesium sulfate, as it’s also known, provides local and systemic anti-inflammatory action. Epsom salt baths can calm itchiness and soothe pain and swelling. However, you have to understand how to use Epsom salts correctly. 

If you want to enjoy the benefits of taking an Epsom salts bath, follow these steps:

1. Run yourself a nice warm bath

The water should be a temperature that you’re comfortable with. Avoid making the bath scalding hot because this will make your skin feel tight.

The water should be lukewarm because this will prevent worsening of your eczema symptoms. 

2. Dissolve 2 cups of Epsom salt per gallon of water. 

For children, the recommended dose of Epsom salt in the bath is 1/2 a cup.

You could add 1/4 to 1 cup of baking soda, as this will further reduce any itching. 

3. Submerge your body completely

Alternatively, you can make a small bath of Epsom salt soak if you have one particular area that’s affected.

Lie back, relax, and breath deeply. The warm water will open your pores and allow the Epsom salt to do its work. 

Aim to soak for between 10 and 40 minutes. To help you relax, try listening to relaxing music, light some candles for mood lighting, and add some essential oils to the bath water. 

4.You could try meditating or deep breathing.

This final step is an optional one. Try 5-5-5 triangle breathing if you’re not sure what to do. You inhale for 5 seconds, hold your breath for 5 seconds, and then exhale slowly for 5 seconds. 

While you’re practicing deep breathing, think about some things you’re grateful for. Watch a TV show on your laptop or something else that makes you feel happy and relaxed. 

You should repeat this Epsom salt bath process 2 to 3 times per week.
