Does anyone have a good way of getting rid of psoriasis?

If anyone has experience using anything to get rid of psoriasis could you please share?
Personally I have tried the vitamin tumeric, which some have had success with but I did not. The dermatologists has prescribed these cortisone type of creams which did not work and are probably unhealthy due to the steroids in the creams. Also I got this cream off the internet which helped remove some of the psoriasis but has not helped the psoriasis on my elbows. I am not usually stressed so that is not a cause. Also I have noticed that when I eat eggs or a lot of sugar/sweets the psoriasis get worse. But if anyone has a psoriasis remedy could you please share?
