Here are overviews of the 12 main organ systems described in TCM. These have functions that differ often greatly from the western medical understanding of the ways the organs function. The energies of emotions are affected by the health of the organ systems. Acumeridian theory is therefore a separate and often very important way to look at a person's life and health.

Recent scientific correlations of emotions with physical health add to the evidence that the autonomic nervous system is affected by the acumeridian system.

You are invited to study this information and to explore some of the related internet sites that, for instance, give help with self-acupressure. After assessment with the AcuGraph, for example, I may give you personalized instructions for self-acupressure to help you with your current health situation.

The 12 main organ systems, in order of their daily circadian energy sequence:
