I will go through the regime I went through. it is somewhere else on GN so hope I don't irritate some of you who have already read it, if so I apologise.
We are a family with psoriasis, my mums dad was hospitalised a few times and my dad had it so, naturally, 2 out of us 4 girls got it reasonably badly, 1 only on her scalp and the other got off scot free!
Mine didn't bother me till I came to live in the uk, no sun!
So boring putting up with it because it never really goes and most of the treatments are either smelly, time consuming or ultimately damage your skin and just stores up trouble in later life.
I was directed to a book written by Dr John Mansfield, first published in 1990. He has in the past been President of the British soc. for Allergy and Environmental Medicine among other things. It is called Arthritis,allergy, Nutrition & the Environment and is, I think, a must read book for anyone with migraines, arthritis or psoriasis.
I followed his diet, very hard at first but I persevered and my skin improved enormously. Sometimes it's difficult to evaluate the improvement as psoriasis is a condition that can come and go but, after 2 years, my skin is so much better. I don't stick to the diet religiously now but have changed my eating habits and it seems to keep it at bay. Just about to have my rhubarb and yogurt for breakfast!
This does take effort but I think it's worth it.
After my last post on this subject I was sent a private message form someone who also followed this path and was very happy with the results.
