I have already been applied for several years in viral infections, along with Nature's Way, Pau d'Arco. Silver take on 0,5-1 teaspoon every 2-3 hours as needed and still drip into the nose, the bark of the tree ant - 1 capsule every 2-3 hours, too. Miracles do not happen, the immune system begins to work a day in the second-third (someone - like). And no more antibiotics, not counting tea with honey and lemon! Take note!
