TCM, a branch of Taoism which includes Feng Shui, is extremely complex and originated thousands of years ago through meticulous observation of nature, the cosmos, and the human body. Major theories include those of Yin-Yang, the Wu Xing (Five Elements Theory), the human body Channel System, Zang Fu organ theory, six confirmations, four layers, etc.
I incorporate my knowledge of TCM and herbs in my practice. (There are approximately 500 Chinese herbs that are in use today of which 250 are commonly used.) I apply TCM observation techniques (tongue, voice, posture, temperature, …) which help me to better understand your present state of balance and wellness.
Qi Gong is another part of TCM that, like the other branches, works with the subtle energies (Qi) to promote health of the body mind or return it to balance. It has been practiced for thousand of years and doctors use it today in China. The following movie comes from the National Qi Gong Association of USA. It depicts a series of Qi Gong exercises which you could integrate into your daily life if you so choose. It is an excellent practice that can help maintain well-being.
