I have suffered with psoriasis for all of 30 years. About 12 years ago I learned about Exorex.(They have a good website with alot of information) I have ordered from them a couple of times and I'm currently expecting an order I purchased. As you know psoriasis never "goes away", but this Coal Tar - Penetrating Emulsion, has put my Psoriasis in remission for 2-3 years at a time. And periodic use keeps it in check, where I have never had any luck with the large number of Doctor perscribed creams or treatments tried. I was wondering if you had ever heard of Exorex (or if you would be willing to look at their website and give me any advice you may have, as everyone - my Doctor included, have never heard of this product). That makes me alittle cautious, but I use it because it does work! Thank you in advance for your time. Sincerely Amy.
