Yes, I believe that this is why I did get a lot of relief from the Psoriasis when I began Iodine supplementing. Iodine plays a vital role in programed cell death, which prevents cells from over-growing. I think that the silica provides the needed nutrients for healing.
The Iodine supplementing has made a vast difference in my fibrocystic breast disease as well, due also to the role of iodine in programed cell death.
Before I embarked on this journey to good health I was severely deficient in many vital elements and minerals. Iodine and magnesium were the ones I was most deficient in.
Overwork, lack of sleep and very poor nutrition are the causes of so much disease in our western societies, I had to address all three of these problems before I could even begin to heal.
