It's best to make this tonic right when you feel like you are getting sick, and drink a serving each morning. If you feel like it is a strong cold, drink one serving in the morning and one at night. And Voila! Your cold will be prevented and/or shortened. Feel free to try this tonic even if you don't have a cold, it's a great immune booster. Make the tonic periodically throughout the winter and you may never catch a cold! INGREDIENTS 1/2 cup Pau d Arco 1/2 cup Yerba Mate 2 in
