I love the stuff!
I have been able to fight off many a sinus infection with colloidal silver nasal spray, I have a generator to produce my own. But having sterile solution in a nasal spray package is so handy.
To produce my own, for oral or topical application, I heat a gallon of reverse osmosis water to boiling, add a scant pinch of sea salt(bet you haven't heard that term since your Grandmother), attach the .999% pure silver wires(12 gauge and NOT sterling(sterling is an alloy, you want pure))to the generator. Then set a timer for 14 minutes(no longer) and wait for the buzzer.
Store your colloidal silver in either glass or a clean hydrogen peroxide bottle(this is because the H2O2 bottle is inert ionically speaking and the silver ions won't bond to the surface.)
Colloidal silver has helped me clear up both bacterial and yeast(heat rash is a yeast)infections.
By consuming no more than 2 ozs. of silver solution a day, you can keep many of the common diseases from settling in your body. In flu season this can be very beneficial.
After the 2004 hurricane season, a neighbor and I came down with a terrible yeast infection of the skin. It ran from our shoulders to our knees in large raised welts that itched like a son-of-a-gun!
I started making the silver up, we drank and applied the silver, we both did yeast cleanses and increased our acidophilus consumption and changed our diets to starve the yeast. It took a few months, but we both cleared up without the liver damage caused by Difluken.
There are several generators out on the market, if you are interested, do your research and go for it.
Or go to this site; http://www.endtimesreport.com/Colloidal_Silver_Generator.html to learn how to make your own generator. Which is like the one I have.
