A Health Watch report, Tea Bag Insulin, by Margot Kim was posted September 21, 2019 by ABC 30 Action News, covering a device developed by Kearchos Papas, Ph.D, and his team at the University of Arizona that allows glucose to go into cells, and islet cells can sense it as they do in the pancreas, and it allows insulin to come out, so it can actually be effective in the tissues that need it.
