Basically, the 3 options listed are "either/or".. *either* one, two, or three may be used. He never specified which tends to work best. And once again, I have no idea of the veracity of the information, but it's not often you'll have Pakistani psoriasis-cure health forum trolls :) posting b.s. cures for the thrill of it, so he probably believes the information is valid. Any questions just ask, but I don't have much more information other than what has been given. Good luck.
