Aurum, gold. One site linked is for Colloidal Gold ; which I tried years ago, before iodine. Had some effect on skin, thats all I can say. Cant find many good reports on gold leafs, but I bet Newport can give some info.
I tried the physical form of gold in may / june, (edible gold leaf) had a temperature increase, from warm to HOT. Had to reduse the iodine.
I wasnt sure if it was the gold or the wheat / grain quit causing this, so for a couple of months I didnt take any gold, kept up all the others, like iodine.
A slightly reduced body temp as a result; from 37.4 to 37. I prefer the former.
I believe my adrenal fatigue / very high stress I have in the fall has its say in this. Not only thyroid run the temp.
