Potassium permanganate, Potash crystals, or Condy's crystals are a dark purple coloured inorganic compound. It has strong oxidising properties. This makes it useful as a disinfectant. It is used to treat skin conditions such as eczema and fungi such as athlete's foot. When it is used on the skin, it tends to stain it a purple colour.

YES Mix about 10 to 20 grains in a bucket of hot water and soak alternate days for a week then stop for a few days and repeat. Your feet may have a light purple color but this subsides quickly. This really works. My mother gave me this cure which is what they used in Egypt. Please note that Potassium Permanganate is a poison if used in large quantities, although it was also used in Egypt to wash their fruits and vegetables but needs to be diluted in water and then rinsed really well. I have only used it for athlete's foot problems.
