Similar notions are dogmas in many cultures worldwide.
Early acupuncturists held that increasing or decreasing the flow of chi could improve health, and that putting diverse needles into hsieh could affect this flow. It was also maintained that chi floated through the air and flowed with blood. Apparently, that the concepts of chi and energy might overlap was not proposed publicly until the 1940s. The proposer was George Souli de Morant, a French doctor who appeared confident that science would eventually demonstrate effects of acupuncture on energetic currents in the human body. This has not been demonstrated.
