Thanks. I also like Olive leaf powder or extract to help ward off illness, but was out of the olive leaf and felt too bad to drive the nearly thirty miles to the nearset health food store to get some. Thank you also for the reminder to gargle or even just rinse the mouth with a little Iodine water. I believe the Iodine is absorbed sublingualy and goes right into the blood stream to start attacking the baddies. It is also good for inflammation of the gums, fever blisters and canker sores.
