Whenever I feel sick, I take colloidal silver. It always fixes me up without fail and has done so since the late 1990’s. That is not to say to drink ThIS product however! .999 silver made with distilled water will not let you down.
I see things totally differently when it comes to internal usage. No medically-accepted evidence whatsoever it does any good, or gets to where it would need to be (cell walls).
