Colloidal silver ( 10-14PPM) has done miracles in my health, and a dozen others I know personally. Many natural healing doctors are using silver in treatments, the one my neighbor uses in north Atlanta has cured many Lyme disease cases.
Also of note: many hospitals are now using silver to kill the MRSA on surfaces. Many years ago I had a house with the dreaded black mold . I mixed up a 200 PPM industrial mix and it killed it all off with one spraying
Application. Do not bad mouth something you have not tried and is proven to work.
