The Book of Tea
The tea-plant, a native of southern China, was known from very early times to Chinese botany and medicine. It is alluded to in the classics under the various names of Tou, Tseh, Chung, Kha, and Ming, and was highly prized for possessing the virtues of relieving fatigue, delighting the soul, strengthening the will, and repairing the eyesight. It was not only administered as an internal dose, but often applied externally in form of paste to alleviate rheumatic pains. The Taoists claimed it as an important ingredient of the elixir of immortality. The Buddhists used it extensively to prevent drowsiness during their long hours of meditation.
