Most say that Addison's disease, causes brown spots or black spots on skin, that would be too much cortisol (stress hormone).

Tan blotches are a sign of liver and kidney weakness. It says to take antioxidants. But the sensiblehealth.com co has great chinese strengthening herbs for the liver& kidney.

Also, White splotches are a vitamin deficiency. Says to take PABA, pantothenic acid, vitamin B6, zinc
