I had skin problems (too dry and very scratchy) i saw specialists who gave me creams ,oils and soft/sweet/idk soaps , exams shows it wasnt an mushrooms ( is it the corret word ) but nothing worked untill i saw on TV that in, france, people eat 5* toom much salt in a day and i was happy trigger on salt.
i 've removed salt from my alimentation (coz it's everywhere in prepared food u buy in supermarkets and streets, fries .... so just by stop puting it in my meals , i would eat too much of it anyway) and bb scratchy skin and problems. I found my own solution ^^ .
i dont if this can help but it cant do bad and it would be better for ur health anyway.
