I, too, have psoriasis. A year ago my plaque Psoriasis had worsened so much that new patches of pustular Psoriasis started emerging. I used to administer topical skin-thinning cortizone-based prescriptions and skin-weathering UVB light treatments. Even those weren't working all that well. Six months ago I stopped all of those treatments and tried some exceptional Tea Tree type products that are healing my condition internally as well as externally. I no longer have the pustular psoriasis. I only have a little plaque Psoriasis on my scalp that is slowly diminishing.
