the single best remedy for strep is 20 ppm colloidal silver. gargle a shot for awhile and then swallow. It can also be sprayed up the nose and is very effective.
for those of you easily swayed by pharma propaganda fear not you will not turn blue unless you drink gallons a day for years. If you do turn blue you will not die you will just be blue.
Good silver products are clear not yellow you can test them by shining a laser pointer through them. if you can see the laser beam in the water its real silver if you can't its just water.
normal preventive dosages are up to a tablespoon a day.
when you are sick its perfectly ok to go through a quart in a day or two.
If you want to make your own dont buy the battery powered machines, they make the lower quality stuff that turns yellow. I would suggest the one from silvergen.com constant current = consistent particle size and higher quality product
