Is Yerba Mate good for you?
Mate tea is used a a lot in some countries in Latin America, and some people claim that is has health benefits (just as there are the same claims for or against coffee or tea). There seem to be a few concerns when it is consumed in large amounts, and I have a link here to a newsletter from the Mayo Clinic which I would consider a reliable source. http://www.mayoclinic.com/health/yerba-mate/AN01774
