What is traditional Chinese medicine (TCM)?

History

The principles of Chinese medicine developed within the larger sphere of the Daoist religion. Primitive acupuncture needles dating to around 1000 BCE have been discovered in archaeologic finds of the Shang Dynasty in China. The theoretical framework underlying the practice of acupuncture was first set forth in the Inner Classic of Medicine, or Nei Jing, first published in 206 b.c.e. during the Han Dynasty. Chinese herbal medicine, however, developed somewhat later. It received its first rudimentary theoretical foundations in the first or second century c.e., but it was not until the twelfth century that the deeper principles of Chinese medicine were fully applied to herbal treatment.

Chinese medical theories involving diet follow along much the same lines as herbal theory. Essentially, each food is an herb and has its own characteristic effects on the body. (A variation of this system known as macrobiotics has become well known.)

The relative importance of the two fields has waxed and waned over time.
Herbology reached a state of high development in the
fourteenth and fifteenth centuries; acupuncture then reached what might be called
a golden age under the Ming Dynasty in the late sixteenth and
early seventeenth centuries. Subsequently, herbal
medicine gained in importance; by the time acupuncture came
back in vogue in twentieth-century China, it had undergone a major transformation
sometimes called the herbalization of acupuncture.

The martial arts also developed within the context of Daoism and, therefore, follows principles consistent with Chinese medicine. The healing martial art known as Tai Chi is said to have been invented by the monk Chang San-Feng sometime in the Middle Ages; however, the exact dates (and even the existence of this monk) are disputed.

In China today, various aspects of TCM are used with conventional Western medical treatment. Considerable attempts have been made to subject acupuncture, herbal therapy, and healing martial arts to scientific evaluation; however, most of the published Chinese studies on the subject fall far short of current scientific standards. (For example, they frequently lack a control group.)

In neighboring Japan, a variation of the traditional Chinese herbal system known as Kampo has become extremely popular, and many Kampo remedies have been approved for medical use by the Japanese health ministry. The scientific basis for these remedies remains inadequate, but several studies of moderately good quality have been reported.

What is traditional Chinese medicine? Traditional Chinese medicine (TCM) is an all-embracing system that, in theory, encompasses all aspects of human existence. Even a basic introduction to its principles far exceeds the scope of this article.

According to the principles of TCM, health exists when the body is balanced and its energy, or qi, is flowing freely. Qi is the life energy that is said to animate the body. The term “balance” refers to the relative factors of yin and yang, the classic Daoist opposing forces of the universe. Yin and yang find their expression in various subsidiary antagonists such as cold versus heat, dampness versus dryness, descending versus ascending, at rest versus active, and full versus empty.

In an ideal state, yin and yang in all their forms are perfectly balanced in every part of the body. However, external or internal factors can upset this balance, which then leads to disease. Chinese medical diagnosis and treatment involve identifying the factors that are out of balance and attempting to bring them back into harmony.

Besides yin and yang, there are five elements or phases that can exist in harmony or disharmony. These are translated into English as wood, metal, water, earth, and fire. Each of these elements has characteristic properties and affects various organs, personality, and overall health in unique ways.

It is important to realize that diagnosis according to TCM differs greatly from Western diagnosis. For example, one patient with a migraine headache might be said to have “dryness in the liver and ascending qi,” while another might be diagnosed with “exogenous wind-cold.” For this reason, there is no such thing as a TCM remedy for migraines per se; rather, treatment must be individualized to the imbalance determined by traditional theory.
