I agree with Beachman, there are different types of psoriasis.
Medical Degree? You think just because someone has a medical degree that I'm gonna take their word as gold?
I'm laughing so hard right now my sides are spliting!
I have proven to myself that psoriasis, at least the case I had, can cure with anti-infective medication....and by the way, if medical degrees are so important I can find a few people with medical degrees who say that psoriasis is caused by fungus.
So take your pick. You can follow the guy with the medical degree who says its not caused by a fungus and never find a cure and spend your life chasing your tail and taking poisonous drugs for it or you can follow the guy who says its caused by fungus, treat it as such according to his recommendations, and get cured.
My husband got psoriasis after a round of antibiotics and steroids for a bad chest infection. The antibiotic even warned of the type of psoriasis that it caused and sure enough, he got it. So, not knowning what to do at the time, it was many years ago now, I picked up a toopical homeopathic cream for it and applied it and it cured up in less than 2 weeks. The remedies in the cream where known for their anti infection abilities and it was kinda a wonderment to me at the time....until I learned much later that psoriasis is often times a fungal infection.
and of course, antibiotics are notorious for causing fungus! now, aren't they?
