Where tea is especially popular, especially in China and Japan, always neglect the tea, which was welded yesterday. In China's culture, yesterday's tea is equal to the true poison, and in the culture of Japan, it is compared with the snake bite. Consider more, whether it is not harmful.
European scientists conducted some studies. Summing up, they concluded that this drink is useful for the body. It acts as a source of nutrients. But its positive properties save tea only if you use it only directly within the hour or two from the bottom of the brew.
But not all people are convenient to brew tea every day. Most brewing this drink for a few days ahead, as it is much more practical. We find out whether it is possible to act in such a way and does not cause harm to the health of tea lovers, especially small.
Of course, the taste quality of tea do not undergo significant changes during the day or even a couple of days. A drink when heated is unlikely to cease to be tasty. Small distinctions of taste will be barely noticeable.

Over time, the useful substances are oxidized, the elements necessary to human organism gradually disappear. As a result, tea gradually becomes a graceful environment for the life and reproduction of harmful microorganisms.

With a second welding, they remain only half, and during the third one third remains.
