Epsom salt is the common name for magnesium sulfate. Epsom salt is most often used in baths. While there is only limited scientific evidence, many bloggers report that Epsom salt baths have many benefits, including helping to soothe tired, achy muscles after intense exercise or due to arthritis; helping to reduce skin inflammation due to conditions like eczema or athlete's foot; and helping to promote relaxation when used in combination with aromatherapy scents like lavender or eucalyptus. If you don't have a full tub, you can try an Epsom salt foot bath. Epsom salt benefits for a foot soak may include relief from itching or discomfort due to athlete's foot or toenail fungus; relief from foot discomfort or inflammation, and a reduction in foot odor. Epsom salt baths and foot soaks are typically safe for most people, but check with your doctor if you have kidney problems or low blood pressure.
