Meridian (Chinese medicine)The meridian system (, also called channel network) is a concept in traditional Chinese medicine (TCM). Meridians are paths through which the life-energy known as "qi" (''ch'i'') flows.
Meridians are not real anatomical structures: scientists have found no evidence that supports their existence. One historian of medicine in China says that the term is "completely unsuitable and misguided, but nonetheless it has become a standard translation." Major proponents of their existence have not come to any consensus as to how they might work or be tested in a scientific context. Provided by Wikipedia
