Things I fee myself and my kids at the first sign of the sniffles
Soup made from real chicken stock after I've cook a chicken,
Shakes with Green Plus in them,
Pure Orange juice non-diluted.
For myself I also take echinecea three times a day.
If we are coming down with a head cold I also add a drop or two of peroxide in our ears and allow it to kill the bug.
WE RARELY GET A FULL FLEDGE FLU/COLD....
