Apple Cider Vinegar -- Take one to two tablespoons of apple cider vinegar and honey (if sugar isn't a problem) in a glass full of water three times a day. Use raw honey if possible. You can also apply it to your skin several times daily by mixing 1 tablespoon of apple cider vinegar into half a cup of water. If you want, you can put the mixture into a spray bottle and just spray it on your skin. There is usually a potassium deficiency in people suffering from eczema and apple cider vinegar has some potassium as well.
