Here are some of my thoughts/theories I have used to help me heal my psoriasis. Psoriasis is an immune response to something which is either coming from something inside your body (what you are eating) or something outside your body (such as skin allergies or abrasion). I believe it can hit you from both sides which is why for some people, eliminating gluten, dairy, nightshades, red meat, etc. help (inside help) and for others using witch hazel and glycerin work (outside help). I started a diet of nothing but sweet potatoes, broccoli, chicken and brown rice, all of which are foods that are relatively easily tolerated by my body and I have noticed very favorable results. I also use the witch hazel (non-alcoholic) and glycerin that helps too but I always apply them separately and witch hazel first. The reason for this (my own reason which you can argue but not prove wrong) is that histamine increases the permeability of the capillaries to white blood cells. Witch hazel shrinks and contracts blood vessels (and capillaries) back to normal size. Also, glycerin provides a good shield/barrier for your skin because it doesn’t absorb into it superfast. Therefore, I first apply the non-alcoholic which hazel by itself to get a stronger shrinking of my capillaries and then wait a few minutes after it is absorbed a little before I apply the glycerin (mixed with water so it’s not so thick) for the skin barrier (that also adds moisture). Anyways, if you are looking for something to try, the diet I mentioned and topical worked for me. Also, the diet is also good for people who workout (sweet potatoes are complex carbs, chicken is an easy to digest protein, broccoli has a good amount of folic acid, and brown rice has a lot of fiber and is gluten free). I also supplement my diet with vitamin D3 and milk thistle.
