hi, i don't have Psoriasis anymore, but i thought i'd share what i learned about it when i did have it.
i got Psoriasis when i was drinking a lot. the depletion of vitamin b along with all the toxins i was poisoning myself with really make me break out.
my healing strategy has been:
vitamin b and c stress tabs
primrose and flax seed oil caps (taken internally and rubbed on sores)
cutting out caffeine and Sugar out of the diet
sunlight sunlight sunlight!
swimming in the ocean is always healing too for so many ailments since the ocean is high in minerals and the water so much alike our own blood!
i also quit drinking and have done fasts and cleanses within the last 13 yrs, but not often or consitantly.
i've had only 1 small patch appear in 13 yrs!
