before going to ant medicine u must know about pron and crons of it
is disease which never cure but surely controlled
what u need is to keep it in control
many doctor or other claim to cure it,but all r wrong
so i advise u to surf net ,there are sites and forum for psoriasis is there.and then decide to go for medicine.
i advise u to not stop allopathic medicine
at any cost,if u want u can go for homeo but continue allopathy.
i have seen many patient who has worse psoriasis after homeo or ayueved treatment
