China is believed to be the birthplace of the tea plant. Emperor Shen Nung, lived about 2737 years BC, has a habit of always boil water before drinking. One day, while resting after the tour in his realm, Emperor asks the servant to boil drinking water. At that time, some leaves, from trees that are not known his name, fell into a boiling pot of water and change color to brown.
Once tasted, the Emperor felt that he drank water becomes more pleasant. The body becomes more fresh. Starting from there, cha, or tea in Chinese, is known.
Other in China, another in Japan. Seed tea was first brought to Japan from China in the 9th century AD by Yeisei Myoan, an homage to the Zen Buddhist priest. Previously, Yeisei have proven efficacy of tea that could make him stay awake while meditating.
