The circadian rhythm of illness

Leaping Real Eyes: The circadian rhythm of illness: "In TCM, the large intestine is responsible for digestion and excretion. However, it also has a role in the immune system of the upper respiratory tracts as the counterpart organ of the lungs (all of the internal organs are paired--the lungs with the large intestine, the stomach with the spleen, the heart with the small intestine, the bladder with the kidneys, the liver with the gallbladder, and the pericardium with an organ-like entity called the 'triple warmer').

The circadian rhythm of illness has been emphasized for thousands of years in Traditional Chinese Medicine (TCM), using this knowledge to schedule therapies such as acupuncture during appropriate hours of the day. This paper reviews the time periods (two hour segments) that apply to each organ system according to TCM (lungs, large intestine, stomach, heart, kidneys and liver), and elaborates on how recent medical research has found similar relevant biorhythms in these very same organ systems.
