A few improvements where psoriasis was minor and secondary to the presenting complaint, but with moderate to severe psoriasis I've been generally disappointed with results using homeopathy alone - tried using high potencies, low daily dose, the lot. Even Jeremy Sherr says he finds it one of the most refractory conditions to treat.I came acroos a book called "Healing Psoriasis" by John Pagano and have been using his dietary methods as an adjunct to homeopathy. It explains that improvement can take months and can aggravate at first. I have two patients using this method at present and though its early days, I'd say things are looking good. I'll keep you posted.
