I have to wonder if this bug is truly a 'virus'. This thing started working its way through the family. After the first 3 kids 'went down', it was time for kid #4 and myself to get it. At the first sign of nausea/'pushed through a knot-hole', I gave us half of 'cow pill'. It's a med for cattle who get 'scours'. Kid #5 and hubby got it, started the vomiting....they got 1/2 cow pill. Knocked it right out.
Just a FWIW. And the 'research' I've done on this med is that it works by killing some 'bad germs' so that the body's immune system can kick in and conquer.
Oh, BTW... this med is listed for use in treating bacterial enteritis caused by salmonella typhimurium, and escherichia coli (colibacillosis) and bacterial pnuemonia (shipping fever)
We use it for our horses who are allergic to penicillin.
Bt- if you need even better germ killer than garlic use high quality oil of oregano, be careful it's powerful!
