For psoriasis, I use 1 spoon apple cider vinegar with water and rub my psoriasis legions with diluted potassium permanganate solution to oxidize the skin after bath. Along with this I use wrightia tintoria oil and expose the legions to sun, which cured my psoriasis 100% in 3 months. But this is not a cure, remission occurs if we don't follow healthy life style.
Note: This only works for non smokers and occasional drinkers.
