Traditional Chinese Medicine (TCM) has a history of more than two millenniums. It has been a common practice in China, Taiwan, Japan and Korea. In recent decades, it is becoming increasingly popular worldwide(Victor S. Sierpina 2005). Studies in Hong Kong, showed that TCM is quite common among children in Hong Kong, with about a quarter of children consulting a pediatrician are concurrently using Chinese Medicine.(Lee 2006; Li 2006).
