I have had psoriasis on my feet for years, and at times of stress a patch appears on my right shin which remains for as long as the stress does, plus I get occasional small patches elsewhere that tend to clear up on their own. I also get it on my scalp. I first had the patch on my shin when I started university. It got larger over the 3 years and it remained for the duration of my course, clearing up after I left. I didn't have it again until I started my current management job, and I've now had it for nearly 3 years. I picked up a pot of Propolis a few weeks ago, and have been testing it on the shin. Though I've only been applying it occasionally, there is a marked improvement and it's starting to clear. This is the only product I'm using on it, after years of trying various pharmacutical and natural products with no success.
