How to get rid of psoraisis? i have been just on the green vegetables diets from last 2?weeks but still i am not seeing much progress

See a dermatologist: Psoriasis sometimes has persistent skin rashes. Topical steroids may be helpful to some people. To treat it will advice you see a dermatologist to discuss the available treatment options.

You cannot: There is no cure for psoriasis and you are wasting your time with green vegetables. These have zero chance of helping. As already suggested. Se a dermatologist.
