Question: does soaking your feet in epsom salt cause diarrhea?
Answer: Safety and Side Effects While Epsom salt is generally safe, there are a few negative effects that can occur if you use it incorrectly. This is only a concern when you take it by mouth. First of all, the magnesium sulfate in it can have a laxative effect. Consuming it may result in diarrhea, bloating, or upset stomach.
