For over 1 ½ years I have been telling people about horsetail grass tea. From some I get: hmm this is interesting, from others just a funny laughter. You can read about the benefits and its effects online. This is in particular important for athletes who have difficulties with injuries. Dr. Feil, a German nutritionist (coaches many pro athletes from soccer teams to pro triathletes) talks about horsetail grass tea in many of his books. He also recommends additional intake of Magnesium, Potassium and Zinc. I will write a more detailed blog in the near future talking about the amounts and effects. You can by Horsetail Grass Tea from www.alvita.com, which is the most effective way of intake, online or at www.wholefoodsmarket.com.
