I am a long standing psoriasis sufferer and have tried sooo many options.
I tried Pagano's diet (even stricter - no dairy or gluten) for nearly a year w/ minor positive results. The teas and the food etc. Did tons of colonics and saunas and even juiced after that for 20 days straight!
My diet does matter of course but a near raw vegan diet and a paleo diet haven't been much better (avoid processed and gluten and dairy) in terms of results.
I do agree w/ Pagano that leaky gut is the culprit although i can't prove that of course.
Aside from slippery elm bark tea and a clean diet what have you done to heal leaky gut?
