What is Epsom salt

Epsom salt refers to a water-soluble mineral compound that has been a popular home remedy for relieving different pain and aches for years. It contains an active ingredient called magnesium sulfate that breaks down once added to water. 

People usually add Epsom salt to their bath to ease muscle soreness. It is also used as a foot soak for the same purpose.

Several studies show that soaking in Epsom salt allows the active ingredient to penetrate the skin. Another study found that the active ingredient can penetrate the skin’s outer layer, depending on how long you soak in it and the salt concentration.

The evidence for the effectiveness of Epsom salt at treating plantar fasciitis and other heel pain issues remains meager.

2017 study highlights magnesium’s effectiveness in reducing pain. However, several studies contradict that finding, stating that the active ingredient shows no difference in reducing pain. 

Should you use Epsom salt for your plantar fasciitis?

People who use Epsom salt on their foot soak or bath claim that it can:

  • Alleviate stress 
  • Detoxify the body 
  • Heal fungal infections, minor wounds, and other feet’s skin conditions 
  • Reduce odor 
  • Repair heel cracks and softens the skin
  • Improve circulation 
  • Relieve minor pains and aches 

While there are no enough scientific studies to support that soaking their feet in Epsom salt can reduce discomfort and pain due to plantar fasciitis, there are some pieces of evidence that small amounts of minerals are absorbed through the skin.

Fungus and bacteria cannot easily thrive in salty environments. However, the benefits tend to come from the soak, not the Epsom salt. 

If you have previously tried soaking your feet in warm water, you know how soothing and relaxing. It also helps promote healing and improve circulation.

What are the benefits of Epsom salt for heel pain?

Even if there is no enough basis for the effectiveness of Epsom salt’s active ingredient for plantar fasciitis, you still have the freedom to soak your feet in Epsom salt.

Taking a hot soak will give your feet time to rejuvenate and rest. Aside from that, here are other benefits you can reap from Epsom salt soaks:

1. Less Athlete’s Foot Symptoms

Epsom salt cannot kill the fungus causing athlete’s foot. On the other hand, it helps reduce moisture, making the environment less appealing for fungus to grow.

2. Eases Inflammation 

There is still no strong evidence that Epsom salt can remove toxins from the body. However, the magnesium’s absorption through the boy helps boost the mineral levels in the body. It also decreases inflammation.

With reduced inflammation, the pain you feel due to plantar fasciitis may also reduce.

3. Promotes Skin Exfoliation 

The Epsom salt’s crystalized compound structure help exfoliates dead skin on the feet. It also helps reduce roughness, leaving your feet softer.

4. Reduces Odor 

 All types of foot soak help clean the feet and reduce odor. Keeping your feet free from bacteria and clean can improve your foot’s overall health.

Is it beneficial to add essential oils to Epsom salt soaks?

Essential oils and Epsom salt soaks are a popular combination. Just like Epsom salt, there is also no enough scientific evidence that essential oils are effective in treating plantar fasciitis; you can still enjoy plenty of potential benefits from combining these two ingredients.

That is especially the case if you find the foot soak pleasant and soothing to the feet. A soak with Epsom salt followed by a relaxing massage with essential oils can calm your body and mind. It also helps improve blood flow to your heels and feet.

The essential oils’ pleasant scent and feel provide extra benefit to your feet, particularly during the healing process.

What are the other home remedies for plantar fasciitis to try?

While the combination of Epsom salt bath and essential oils helps improve the symptoms, the plantar fasciitis’ true healing starts with treatments that address the inflammation and damage to the ligament called the plantar fascia and its surrounding muscles.
