Functional circuit, pathway or channel through which, according to Traditional Chinese medicine (TCM), the life energy (Qi) flows.

There are twelve main channels, each of which is assigned to one organ system. On the meridians themselves, there are special points where – e.g. through needles (acupuncture) or finger pressure (acupressure) – the energy balance can be influenced.
