Natural Health: I’ve tried everything to cure psoriasis

Q. It seems to get worse during stressful times, and also when I am pregnant.

I usually have it on my arms, legs, and scalp, but sometimes it spreads across my entire body. I have tried almost everything over the years, and nothing has really made a difference. 

I find that aqueous cream helps to relieve the dryness and itching. Is there anything more I can do? I have accepted that this is a part of my life, but I am still very self-conscious about how it looks.
