Last year Ben Kavoussi published an interesting article on SBM called Astrology with Needles in which he purported a historical connection between acupuncture and bloodletting. I had previously thought that bloodletting was a uniquely Western cultural invention – part of Galenic medicine involving the balancing of the four humors, one of which being blood. (In the West bloodletting faded away with the advent of science-based medicine in the 19th century.) I was intrigued by this connection and have since been doing my own reading on the topic. It turns out that bloodletting was common throughout ancient cultures and not unique to the west.
In fact acupuncture was originally a form of bloodletting – the “needles” were really lances and the acupuncture points locations over veins to be opened. Chi, or the Chinese concept of the life force, was believed to be partly in the blood, and blood letting could be used to free the flow of chi. This was closely related to the Galenic concept of using bloodletting to free the flow of static blood in the tissue.
For example, in the ancient medical text of Suwen, we find:
When heaven is warm and when the sun is bright,
then the blood in man is rich in liquid
and the protective qi is at the surface
Hence the blood can be drained easily, and the qi can be made to move on easily…
