I have suffering from P for past 7 years (mostly scalp), recently I got two red patches on my face and was very embarassing to go out. Last week I went to Myrtle Beach, SC and went for swimming in the ocean for three days (less than an hour per day), By the time I came back from vacation my patches on face are gone, the skin is in natural color but a little softer than regular skin. I dont know how long this thing lasts but it was a BIG relief to me, now I can go back to work with pride. Iam drinking Elm tea and Saffron tea, they gave some relief initially but now they are not much of help but I still continue it.
