Both my wife and I have had great experiences with the colloidal silver we have obtained from Mr.Boch. My wife uses it for sinus infections that she has on a regular basis this stuff clears it right up. Myself I use it as a part of my nutritional value daily. My wife tells me my skin has a nice healthy glow to it since I have been supplementing with the colloidal silver.
Thanks SGA colloidal for such a great product.
