What is Epsom Salt?

epsom salt uses

Despite the name, Epsom Salt isn't actually a salt all. Its chemical name is magnesium sulphate, whilst its common name originates from the spring in Epsom Surrey (England) where this naturally-occurring mineral was first discovered.

The skin readily absorbs both magnesium and sulphates, which can have some amazing bodily effects such as reducing inflammation, flushing toxins, easing migraine headaches, helping muscle and nerve function and much more.

Whilst Epsom Salts are primarily known as being a natural remedy for ailments, there are lots of other things that can benefit from them too.

Health benefits of Epsom Salt

1. Promotes rest & relaxation

Are you feeling sleepy?

Are you feeling tired and stressed out? Epsom Salts could help!

Epsom salts will dissolve in warm water and, as previously mentioned, can be easily absorbed by the skin. This is why they can often be found in high street bath salts and expensive spas.

The magnesium ions break apart from the Epsom salt molecules in water, and as they penetrate your skin it increases the production of serotonin (the happy chemical) and reduces adrenaline, helping you to feel nice and relaxed. The magnesium is also said to help the production of energy in cells which make us feel invigorated.

So if you’re feeling particularly stressed out or anxious, take a cup of Epsom Salts and mix them into a nice hot bath to:

      • Feel more relaxed
      • Alleviate stress or anxiety
      • Gain a sense of well being
      • Feel invigorated

2. Soothes pain & muscle tension

If you work at a desk all day, or indeed, work out a lot, then you're sure to have muscle tension or knots. An Epsom salt bath can have a really positive effect, working to relieve muscle tension and pain while also soothing inflamed joints.

Have a therapeutic Epsom salt bath to:

      • Alleviate a tension headache
      • Relieve muscle tension
      • Soothe tired and sore feet
      • Loosen tight muscles

They can also be useful when you're suffering from the flu. Epsom Salt baths will ease discomfort and help you to get the rest you need to recover.

3. Relieves constipation

According to the Epsom Salt Council, the magnesium and sulfate components can have a laxative effect when drunk. An Epsom salt drink could be the answer to your uncomfortable constipation.

Here's how to make and ingest one safely:

1. Pour 110 ml of water into a glass and 1 tsp of Epsom Salts to the water.

2. Dissolve the mixture by stirring thoroughly with a spoon - add a squeeze of lemon juice if you wish.

3. Drink the water in a few gulps - you should expect your next bowel movement between 30 minutes and 6 hours of drinking.

The same mixture can also be taken orally to 'detox' the body, which some claim to contribute to healthy weight loss.

NOTE: Talk to your doctor before using Epsom salts as a laxative if you have any health conditions, allergies or are taking other medications or supplements. People with kidney disease should not take Epsom salts.

4. Helps remove painful splinters

Ouch! We all get splinters from time to time. They can sometimes be extremely tricky to get out, and almost impossible if deeply nestled into a child's little finger.

Epsom salts can provide a pain-free solution as magnesium sulfate helps reduce any inflammation to help the splinter become loose, making it easier to ease out.

TRY IT: Soak the affected body part in a solution of warm water and Epsom salts for a few minutes to help remove a stubborn or deep splinter.

5. Treats Athlete's Foot & other fungal nasties

Soaking your feet in an Epsom Salt bath will help relieve aches and pains, but it's not only good for that.

Along with their soothing properties, Epsom Salts are also very good at treating Athlete's Foot and other toenail fungal infections.

TRY IT: Dunk your feet in a bowl of hot water and a cup of dissolved Epsom salts until the water goes cold, then gently buff your feet with a soft towel.

6. Works as an alternative to Aloe Vera

Most of us know that Aloe Vera can be pretty remarkable as a natural home remedy, but did you know Epsom Salts are just as good for many things?

Similarly to Aloe Vera, Epsom Salts can Soothe mosquito bites, bee stings and even mild sunburn. When used, the minerals start working almost immediately to reduce inflammation and soothe the skin.

TRY IT: Soak a washcloth in a cold water Epsom Salt solution (2 tbsp Epsom Salts per cup of water) and gently press onto the affected area to provide quick relief.

7. Treat thrush & yeast infections

Yeast infections can be pretty painful and can get worse if left untreated, so it's always advised to act fast.

Alongside antibiotics, which the doctor may recommend, and keeping hydrated, an Epsom Salt bath can also help alleviate pain. They work to alkalize the pH of the vagina and are also antibacterial.

8. DIY eyewash

If you ever happen to get a swollen eye or conjunctivitis, you'll be grateful to have some Epsom salts lying around - when mixed with warm water, they make a great DIY eyewash to reduce inflammation and bacteria.

9. Epsom salt bath for dogs

Not only that, but it can also assist with healing and reduce swelling after injuries.

Beauty uses for Epsom Salt

10. Exfoliate your skin

Exfoliation is highly beneficial to the skin, as it helps to remove dead and dry skin cells, allowing new ones to surface and receive the nourishment they need. This not only helps with skin health, but appearance too, and it will leave you with soft, supple, glowing skin.

As Epsom Salts have a gritty texture, they make an ideal ingredient for a homemade body scrub for your hands, legs, arms, torso and back.

Not sure whether you should shave or exfoliate first? Read our handy guide now!

TRY IT: Mix a cup of Epsom salts with a natural oil like Coconut or Olive Oil in a small bowl (add your favourite essential oil if you like) and give it a thorough mix.

11. Deep-cleanse a congested face

Epsom Salt's miraculous mix of ingredients can give your skincare products more power than ever. For fresh and bright skin, why not add some to your daily cleanser?

TRY IT: Grind a teaspoon of  Epsom salt in a pestle and mortar or give them a crush with a rolling pin. When you have finer dust, mix it in a small bowl with your regular cleanser. Gently massage the mix into your skin, carefully avoiding the eye area, then rinse with warm water.

12. Clear out blackheads

Epsom salts could improve your skin!

Blackheads (dermatologically known as open comedones) are extremely common. Their black colour is caused when pores become blocked with dead skin cells and sebum (the skin's natural oil).

They can be tricky to eradicate completely, but one of the natural remedies you can try is Epsom Salts.

TRY IT: Add 1 tsp of Epsom Salts and 3 drops of Iodine into half a cup of boiling water. Mix and let cool for a few minutes. Then, dip a cotton wool ball into the solution and apply to areas affected by blackheads. Finally, use clean fingers, to apply a small amount of pressure to the surface of your skin to gently dislodge any gunk.

13. Volumise your hair 

Forget spending a fortune on expensive hair products - it turns out Epsom Salts can also be used for volumising hair.

TRY IT: Combine equal parts deep conditioning conditioner and Epsom salts and lightly warm in a pan. Massage the mixture into your scalp and hair then leave for 20 minutes under a shower cap. Rinse thoroughly and dry to reveal bouncier, bigger hair.

14. Remove hard skin on feet

Hard skin on feet not only looks pretty unsightly, but it can actually cause discomfort too. Epsom salts are also a cheap and practical solution for this.

TRY IT: As per the instructions above, make a scrub and brush it into the soles of your feet. Once you've scrubbed the hard skin, leave your feet soaking in a bowl of warm water for a minute or two - you'll have buttery-soft skin in no time at all!

15. Treat back acne

It's hard to know just how to treat back acne. Whilst it's much less noticeable than face acne, it can still be unpleasant and itchy.

An Epsom Salt bath soak is one way to treat back acne gently. Not only is it completely natural, but it solves the problem of getting at those hard-to-reach areas.

 Epsom Salt allergy symptoms

Whilst most people do respond well to Epsom Salts, there are those that may be allergic to this natural mineral.

If you experience any of the following symptoms, it could be that you're either allergic to Epsom Salts, using them wrongly, or they do not agree with your body. 

      • Diarrhoea
      • Toxicity - vomiting, drowsiness, nausea
      • Rashes, itching or swelling
      • Hypotension - dizziness and shock

In such cases, stop treatment immediately and consult your doctor.

    Hi, Love your tips and will be trying out quite a few of them thanks. My question is: do you spray the epsom salts/water solution directly onto the foliage of plants for better flowers or spray it around the the base pf the plants on the soil? is this suitable for mist types of plants including more exotic ones like hibiscus or dipladenias?

    1. Author Joanne A on October 15, 2018 at 10:51 am

      Hi Michelle! We're glad you found the tips helpful. We suggest applying the Epsom salt solution to the soil of the plant or flowers. It would be suitable for all plants.

  5. Author Melanie Pickering on October 27, 2018 at 12:36 pm

    I find so many of the tips you post interesting but would it not be possible to print them out in a print-friendly fashion? Pressing the print button brings the pages up pretty much as they are, although bits are normally missing from the bottoms of the pages (so sometimes you don't get the bit you wanted printed). The photos are not necessary for the tips so it would be nice to reduce the amount of paper used.
