I am notorious for foisting this kind of thing on friends LOL Here is my recipe, that works:
Chicken soup, loaded up with garlic and pepper. Garlic is a wonderful antibiotic, and pepper speeds up the metabolism to help get it through your system.
After the chicken soup has been eaten, it is time for the "witch's brew" which consists of chamomile tea with lemon juice and honey
Chamomile tea is a natural sedative and helps them rest, while honey is for the cough (don't know why it works, it just does) and lemon juice for the sore throat (old choir trick that always works!).
Lather rinse repeat until the patient is well enough to throw you out LOL Then next time the bug comes around you will get another phone call for the chicken soup freom hell and the witch's brew! It worked in the barracks LOL
