I drink the herbal tea for years of Eilles and am very satisfied. Because of lactose and fructose intolerance I vetrage hardly fruit teas, as most teas give heartburn. There are even lactose-free teas that contain no artificial flavors. I was very surprised! And there is Eilles which is always worth a try. I use approximately 1 liter of water just a tea bag and it tastes good. No heartburn. Can imagine, the cold also tastes the tea good, but I would then take 2 tea bags in a quart.
