Epsom Salts – Baths and Beyond


Epsom salt bath

There is nothing better in winter than a nice hot bath.  And a bath that was prescribed by your Naturopathic Doctor is even better.  Just tell your partner, roommate or kids that you *need* to spend 20 minutes enjoying a quiet soothing bath – your doctor told you to do it.

Why take an Epsom Salts bath?

An Epsom salts bath releases toxins and metabolic waste by enhancing perspiration.  Epsom salts also contain magnesium sulfate, which when absorbed by the body promotes muscle relaxation and relieves stiff, aching and cramped muscles.

Epsom salt baths can also be used to treat specific conditions.  Dry skin can benefit from Epsom salt baths as can genital herpes outbreaks.

The Epsom Salts bath

Step 1: Add two cups (approximately 600g) of Epsom salts to a hot bath (38 to 44 degrees Celsius or 100.4F to 111.2F).  Soak in the hot bath for 15 to 20 minutes.

Step 2: While in the bath wrap a cool wet towel around your neck (a hand towel dipped in cold water works well) and drink cool filtered water to replace fluids that are lost.

Step 3: When finished the bath, cool your body down with a cool shower or a cool sponge bath – starting from the feet and moving upwards.

Step 4: Rest for 15 to 30 minutes after the bath for maximal relaxation and therapeutic impact.

Additional notes:

  • Do not use soaps while in the Epsom salt bath.
  • Taking an Epsom salt bath after a massage can enhance and lengthen the effect of a massage.
  • Take an Epsom salt bath two to three times per week for best results.

Other Uses for Epsom Salts

Epsom salts can be used to treat acne and skin blemishes.   Mix 1 tablespoon of Epsom salts in ½ cup of warm water.  Wash face with the mixture twice daily.  Use just once daily if you have very sensitive or dry skin.  Discontinue use if skin irritation occurs.  You could also use a poultice and apply just to blemishes (see below for instructions on how to make a poultice).

A Epsom salts poultice can also be used to draw out boils, carbuncles or abscesses.  The salts are a natural antiseptic and antimicrobial and help to absorb the moisture from the area, drying out the boil.  Use a poultice and apply to the affected area for 5 to 10 minutes then rinse with cool water.


Place 1 to 2 tablespoons of Epsom salts in a glass bowl

Add just enough warm water to make a thick paste

Apply to blemishes, boils, carbuncles, abscesses or herpes outbreaks once to twice daily

Leave on skin for 5 to 10 minutes then rinse off with cool water


Epsom salt baths are relaxing to your body and mind but are stimulating to your circulatory system.  It is not recommended for people with high blood pressure or severe varicose veins to use Epsom salt baths.
