Chrysanthemum drink!!!!!
Chinese Chrysanthemum drink!! It's something that I used to take when I felt like I was getting sick and it would stop it right there. Some of my mom's friends from China passed this remedy on to us and I still drink it years later. I get it from the Asian grocery. It tastes the best when it's hot. It's amazing.
Zinc and Echinacea also work well for me if I take them regularly when I'm around sick people.
