The term pyroluria is not found in most medical journals that I have looked at. It is a condition though which I as a physician have seen many times and the treatment is good to excellent and usually requires nutrients only.Often one can see an imporovement in a week or two.

. Histapenis is more common in my experience. It takes longer to treat but generally speaking nutrients make a great difference.
