Being healthy doesn't mean never getting sick. If you are healthy and you get sick, you are able to bounce back. You are able to mount an appropriate immune response to a virus or bacteria. You are able to listen to your body, and sleep when you are tired, drink water when you are thirsty, and eat foods which truly nourish.
Garlic and ginger are great allies in the fight against germs. Chicken soup does have healing properties. Fresh ginger (about an inch in size) sliced and simmered for twenty minutes in two cups of water, makes a wonderful steam for stuffed sinuses, and then you can add a teaspoon of honey and a spritz of lemon for a soothing tea. Fresh garlic can be minced and spread on toast and covered with honey for a medicinal snack. Hippocrates said,"Let your food be medicine and your medicine be food."
