The history of tea dates back to ancient China, almost 5,000 years ago. According to legend, in 2732 B.C. Emperor Shen Nung discovered tea when leaves from a wild tree blew into his pot of boiling water. He was immediately interested in the pleasant scent of the resulting brew, and drank some. Legend says the Emperor described a warm feeling as he drank the intriguing brew, as if the liquid was investigating every part of his body. Shen Nung named the brew "ch'a", the Chinese character meaning to check or investigate. In 200 B.C. a Han Dynasty Emperor ruled that when referring to tea, a special written character must be used illustrating wooden branches, grass, and a man between the two. This written character, also pronounced "ch'a" symbolized the way tea brought humankind into balance with nature for the Chinese culture.
