How does Epsom salt draw out toxins?
One of the best-known ways to leach heavy metals from the body is through the skin, submerged in a salt bath. The sulphates in Epsom salt help flush out toxins and heavy metals. The process is called reverse osmosis, and it literally pulls toxins out of your body.
Navy soldier told me a long time ago, they also use them for that kinda thing.

Very good for Burdened feet.
