Forearm Skin Diagnosis
Updated 2026-08-01
INTRODUCTION
English translation pending.
CORE DEFINITION
A method in Chinese medicine, recorded in the Huangdi Neijing, in which the practitioner feels the skin from Chize (LU5) at the elbow down to the wrist at the inch opening. The skin is assessed for temperature, moisture, and texture. Heat with dryness suggests a heat pattern, coolness with moisture suggests cold-damp, and scaly, withered skin points to exhausted essence and blood. The key qualification is that the ancients considered it more direct than pulse reading, yet it remains one sign among several and must be combined with the pulse and other findings.
SCAFFOLDING EFFECT
Reduce cognitive load
- Fallback probe: use the forearm skin when the pulse is ambiguous or hard to read. - Texture read: convert temperature and moisture findings into a first hypothesis about cold, heat, or depletion. - Cross-check: compare the skin finding against the pulse before committing to a pattern.
Anchor fast decisions
Skin temperature and moisture reflect peripheral circulation and the body's fluid balance, which shift systematically in cold, heat, and deficiency patterns. Because the forearm is easily accessible and richly supplied with superficial vessels, its condition registers changes that the pulse may blur. This makes it a redundant channel of evidence, useful precisely because it is independent of the pulse and can either confirm or contradict it.
