Magnesium Sulfate (Epsom Salts) is one of the best external treatments I have ever seen for healing eczema and psoriasis (Yeast). You can dissolve about 2 cups of Epsom Salts into a bathtub of warm water and soak for 20-30 minutes in it once a day...use the time to relax and meditate, perhaps light a candle and put soft music on. This will also help to grow out healthy nails and will eliminate another side-effect of yeast; thick callouses on the feet!
