The relationship between the organs and the meridians
The relationship between the organs and the meridians: connected but not identical
In Traditional Chinese Medicine, organs and meridians form an inseparable whole. They are connected, constantly influence one another and bear each other's names. But they are not identical — and that distinction is clinically crucial. A good understanding of the relationship between organs and meridians gives the TCM practitioner the nuance needed to make accurate diagnoses and plan targeted treatments.
A bidirectional relationship
The relationship between organ and meridian is bidirectional: a problem in the organ can affect the corresponding meridian, and conversely a problem in the meridian can influence the corresponding organ. This is the basis of distal acupuncture treatment: by needling a point on the Liver meridian on the foot, one can influence the Liver itself — even though the distance between the point and the organ is considerable.
Meridian and organ as separate layers
At the same time, it is essential to be able to regard organ and meridian as separate layers. The meridian runs more superficially through the body — through muscles, tendons and skin. The organ is located in the interior of the body. A pathogen or trauma can affect the meridian without the corresponding organ being affected.
A classic example is tennis elbow with pain along the pathway of the Small Intestine meridian. If there is no other indication of a Small Intestine organ disorder — normal stools, no abdominal complaints — then the problem is probably limited to the meridian itself, without involvement of the organ. Treatment then focuses on releasing stagnation in the meridian, not on treating the organ.
The reverse is also possible: someone with chronic digestive problems and abdominal distension may secondarily develop pain in the arm along the pathway of the Small Intestine meridian — not because of local trauma, but as an expression of the organ disorder along the meridian. And sometimes an organ is disturbed without the corresponding meridian showing any complaint — the disorder is then located exclusively in the internal layer.
Clinical consequences
This distinction has direct consequences for diagnosis and treatment. With pain along a meridian without organ symptoms: treat the meridian locally and distally. With organ symptoms without meridian complaints: treat the organ through its specific points. With a combination of both: treat both layers, with attention to sequence and priority. The TCM practitioner who can analyse organ and meridian as separate but connected layers has a richer and more precise diagnostic framework than one who treats them as a single whole.
