Hi I m wondering if Doxycycline - the tetracycline antibiotic - will help plaque and inverse psoriasis. I have red scales of psoriasis on my face and in the folds of my skin. I m healthy and of average weight. I ve been researching that psoriasis is parasites and bacteria which tetracycline claims to help treat. I live in a cold climate which doesn t help. If I m in a tropical humid climate my skin tends to sweat out the toxins and my psoriasis disappears.Any suggestions to get rid of the discomfort and occasional bleeding (I ve tried a lot of things!)
