Does Epsom Salt Expire

Epsom salt is the common name of a chemical compound known as ‘magnesium sulfate.’ It’s made up from magnesium, sulfur and oxygen. It serves as a healing agent for our bodies since it can ease swelling from sprains and bruises without any negative side effects. It also reduces the inflammation from sunburn.

 

Read on and we’ll tell you if Epsom salt does expire, the benefits and uses of Epsom salt, and where it can be bought.

How Does Epsom Salt Work?

Epsom Salt, aka magnesium sulfate, has many purpose and works in different ways. Epsom salt is named after the town in England where the compound was first discovered in springwater. The most common use for Epsom Salt is as a laxative and reliever of muscle soreness. It’s even approved by the FDA as a natural laxative. The mechanism behind Epsom Sal is that when dissolved in warm water, your body will absorb the magnesium through the skin, helping muscles relax and also helping to reduces inflammation.

 

Magnesium plays a very important role in our bodies, from assisting muscle contraction to immune system response, so it’s definitely possible that Epsom salt truly does work for muscle soreness.   

There’s not a ton of evidence that Epsom Salts truly does help relax and heal sore muscles, but the fact remains that a warm soak certainly does in our experience! A warm soak helps promote blood flow and muscle relaxation, so the addition of Epsom salt to allow your body to absorb minerals is definitely a plus in our book. 

Does Epsom Salt Expire?

Does Epsom Salt Expire? Nope! Epsom salt (also called bath salts or magnesium sulfate) is a naturally occurring mineral and it does not expire. Epsom salt is usually labeled with a “best before” date. That date isn’t necessarily an expiration date.

 

Even if the Epsom salt / magnesium sulfate is past its labelled expiration date, it will not lose its efficacy. Epsom salt expires when it ends up making contact with moisture for prolonged periods of time. It is strongly recommended that when storing Epsom salt, make sure it’s in a dry room, away from humidity, in an airtight container away from direct sunlight.

 

How you store Epsom salt will make a big difference in how long it lasts. If stored correctly in a sealed container, Epsom salt will last a long time. Since table salt does not expire either, we’ve found that storing Epsom salt with other salts is a good plan- just label them clearly!

 

If kept for many years, even though it will most likely harden or clump up, you can just break or dissolve the solid part. This can be prevented by keeping it tightly sealed in its original packaging or any airtight containers in which water will not be able to get inside it.

 

Storing Epsom salt in a dark place is also recommended. exposure to sunlight can promote microbial growth, which nobody wants!

 

Like in any medical product, the law requires Epsom salt as well to put an expiration date in its packaging. Even so, the expiration date really only indicates that the Epsom salt will not get hard or clump before the actual date.

 

That’s assuming that the Epsom salt is kept in a dry, cool place, similar to how you’d store your canned food with an expiration date. Exposure to water can ruin the shelf life of Epsom salts, just like table salt. Moisture exposure is something you need to worry about more than time. 

 

But long story short, the expiration date does not mean much and Epsom salt doesn’t go bad. It’s a bit more of a suggestion than a hard-and-fast rule. 

How is Epsom Salt Used?

Epsom salt is also known as ‘bath salts’ (a real bath salt), so folks dissolve it in a bath to soak their bodies. A cup of Epsom Salts in hot water is the standard Epsom salt bath. Epsom salt is also a natural laxative that can treat constipation as well. It can be used as an emergency dish detergent (be sure to rinse well!) along with warm water too. 

 

Epsom salt earned its way into the Prepper’s Bug Out Bag /Bugging In home supplies. Epsom Salt can help cramped muscles by getting magnesium into the skin during an Epsom salt bath. The same can be said about bruising- a bad bruise will heal much more quickly after a hot bath in Epsom Salts.

 

Aside from helping with muscle soreness, the biggest benefit of Epsom Salt taking care of your skin. And that starts with blisters and taking care of your ever-important feet. You’re going to be on your feet all day in a SHTF situation. Epsom Salts can help deal with that.

 

Here are some of the many benefits of a nice soak in Epsom salt.

Regardless, The magnesium- rich minerals of Epsom salt soak will give some degree of relief to dry and itchy skin, especially from mild allergic reactions.

Constipation Relief With Epsom Salt

Magnesium, the main component of Epsom salts, does have laxative effects. This appears to be the case because Magnesium draws water into your colon, which promotes bowel movements. Most folks simply take Magnesium citrate, but in a pinch, Epsom salt will work as well. The FDA even approves it for use as a laxative. Again, the expiration date really doesn’t matter.

 

Now remember, if you have access to a conventional laxative, you should probably use it. Even though epsom salts don’t go bad, it’s still a last resort. We are only talking about using Epsom salts as a laxative in a survival or emergency situation.

 

Here’s how to take Epsom Salt for constipation:

Most adults only need 2-4 teaspoons of Epsom salt with 8oz of water, effect may take between 30 minutes and several hours, so be prepared! Some people report side effects of bloating, but that’s pretty much it.

Epsom Salt as a Sleep Aid

A big effect from that is difficulty sleeping. The magnesium in Epsom salt will help your body product serotonin, therefore promoting healthy sleep.
