I have been reading about apple cider vinegar 2tsp, with 4 drops of stevia or 1tsp of honey, with clean drinking water. This recipe is also on the back of of the Braggs apple cider vinegar bottle. I would also add essential vitamins and probiotics. I have had Psoriasis for about 8 years now. I just recently (2 days ago) started on the acv. I already feel less itchy. It is supposed to have a lot of the vitamin b's in it.
