1. Oranges are packed with vitamin C to build up your immunity. I suggest squeezing your own or buying organic without added sugar. 2. Apple Cider Vinegar is the best cure-all to keep around. Again, I always buy organic with "the mother"... AKA the cloudy stuff. I added a table spoon to my orange juice. If you don't like the taste of vinegar, that's the way to go so you wont taste it. 3. Warm liquids jump start immunity and soothe sore throats. Tazo Green Ginger and Tazo Rest are my current favorites. 4. Organic local honey can soothe sore throats and relieve allergies.
