Traditional Chinese Medicine
Traditional Chinese Medicine, also known as TCM, includes a range of traditional medical practices originating in China. Although well accepted in the mainstream of medical care throughout East Asia, it is considered an alternative medical system in much of the western world.
TCM claims to be rooted in meticulous observation of nature, the cosmos, and the human body, and to be thousands of years old. Major theories include those of Yin-yang, the Five Phases, the human body Channel system, Zang Fu organ theory, six confirmations, four layers, etc. Modern TCM was systematized in the 1950s under the People's Republic of China and Mao Zedong.
