Over the course of its development, ancient practitioners developed concepts and systems reflecting the religious, medical and cultural beliefs of their time.
Archaeological relics and manuscripts give us a clue to understanding the history and development of acupuncture. Ancient practitioners examined their patients by feeling pulsations at various points. They believed that the pulse was an indication of a vital force, which they called Qi.
The difference between life, death and quality of health was due to the presence or absence of Qi. Channels were connected between various acupoints, forming a network of meridians. The theory of meridians became one of the cornerstones of traditional Chinese medicine (TCM). The most valuable discovery in acupuncture theory was the interrelation between parts of the body surface and the internal organs.
