Autoimmune disease...probably started from poor diet ie this is mainly westerners disease.
also maybe from lack of sunshine...vitamin d and sunshine and saltwater noted above seem to be best natural remedies ive found
most the drugs to treat it are pretty bad...steroids just treat symptoms and arent good for skin long term..long term work on diet...sunshine and fitness and stress.
people with psoriasis have higher likelyhood of arthritis and cancer.
can get vitamin d treatment from doctor
