An old holistic remedy: Finely chop 1 clove of garlic ( not the whole bulb). Let it sit for 10 minutes or so. A substance called allicin is released which is anti-bacterial and anti-viral. Chew it ( try to keep it on your teeth as it is hot). You can add a teaspoon of honey if you like. I just drink water after I swallow it. Cooking destroys the allicin ingredient. It truly works but people don't believe it or like garlic. My DD and DGD were very sick coughing, sore throat, stuffed up heads, just miserable and finally agreed to try the garlic. Within 1-2 hours they were feeling so much better and by the next day all symptoms were gone!
I have shared with others I know and they poo-poo it and stay sick...
