Gui Jing (歸經) — Meridian Tropism

In gui jing classification, a substance assigned to the Lung channel is discussed as acting through the Lung network, especially its qi and dispersing/descending functions. The point is a target-organ projection placed in the thoracic region for visual legibility, not a claim that herbs travel along a surface line.

The Large Intestine channel-entry label identifies a substance affinity in the zang-fu network used by materia medica texts. Its dot is editorially placed beside the lower thoracic/upper abdominal field and does not depict bowel anatomy or an acupuncture trajectory.

A Stomach channel-entry designation indicates a substance relationship to the middle-jiao digestive network in clinical herbal classification. The upper-abdominal dot is a target-organ projection, not a surface stomach outline or a guarantee of pharmacological action.

The Spleen channel-entry category concerns the TCM Spleen network and its transformation and transportation of food essence. The point uses an upper-middle abdominal projection to make that functional target visible, rather than asserting a direct anatomical route.

A Heart channel-entry designation names affinity with the Heart network in the materia-medica tradition. The midline chest point is a functional target-organ projection and should not be read as a map of cardiac drug distribution.

The Small Intestine channel-entry category belongs to the paired Heart–Small Intestine functional network in TCM classification. The point is offset in the torso as an editorial target projection, not a claim about an anatomical surface channel.

A Bladder channel-entry designation indicates a relationship to the Bladder network and its fluid-transforming functions as described in herbal references. The lower-trunk dot is a target-organ projection with a broad uncertainty radius, not a bladder contour.

The Kidney channel-entry category identifies affinity with the Kidney network, the classical root of essence, water metabolism, and constitutional functions. The lower-back/abdominal projection is deliberately schematic and must not be mistaken for a surface anatomy map.

The Pericardium channel-entry label is used in modern channel-entry lists for the Heart-protective network. Because the ontology has no separate pericardium tag, the point carries the broader organ and meridian tags; its chest location is a target-organ projection, not a claim about the pericardial sac.

The Triple Burner channel-entry category names a functional network that distributes qi and fluids across the three jiao in TCM theory. The central torso dot is an editorial composite target projection because the Triple Burner is not a discrete anatomical organ.

A Gallbladder channel-entry designation indicates affinity with the Gallbladder network in materia-medica classification. The lateral upper-abdominal position is a broad target-organ projection and does not reproduce a gallbladder surface outline or channel path.

The Liver channel-entry category indicates affinity with the Liver network and its classical roles in storing blood and maintaining free coursing. The anatomical-right upper-abdominal dot follows the front-view convention but remains a functional target projection rather than an anatomical map of herbal action.
