What Is TCM Pulse Diagnosis?

How Pulse Diagnosis Works

In TCM, the pulse is the most direct expression of the state of the internal organs and the quality of Qi and Blood. The three positions on each wrist — Cun (inch), Guan (bar), and Chi (cubit) — correspond to different organ pairs. On the left wrist: Heart/Small Intestine (Cun), Liver/Gallbladder (Guan), Kidney Yin (Chi). On the right wrist: Lung/Large Intestine (Cun), Spleen/Stomach (Guan), Kidney Yang/Pericardium (Chi).

Each position is assessed at three depths — superficial (Qi and Yang-natured conditions), middle (organ function), and deep (Yin, Blood, and deep pathology). An experienced practitioner integrates the information from all 18 positions into an overall picture of the patient's constitutional pattern.

What the Pulse Tells Us

The quality of the pulse provides information that no other examination method can access. A 'wiry' pulse (taut, like a guitar string) in the Liver position indicates Liver Qi stagnation — common in stress and pain conditions. A 'slippery' pulse (smooth, like rolling beads under the fingers) indicates Phlegm-Damp accumulation. A 'deficient' pulse (weak, barely perceptible) indicates Qi or Blood deficiency.

Pulse diagnosis takes years to master and is considered the most difficult of the four TCM examination techniques. It is one of the distinguishing features of TCM practice from simplified acupuncture approaches that omit constitutional diagnosis.
