Fissured Tongue
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
The tongue surface has fissures or cracks of varying depths. This is often due to depletion of essence and blood, consumption of body fluids, and loss of nourishment of the tongue body.
SCAFFOLDING EFFECT
Reduce cognitive load
Drought and cracking. The earth (tongue) cracks because of prolonged drought (yin deficiency) or lack of blood moisture. The deeper the cracks, the longer the drought, indicating that the deep water source (kidney essence) has dried up.
Anchor fast decisions
A tongue with vertical and horizontal fissures often indicates deficiency of yin and blood or spleen deficiency with dampness invasion. Diagnosis should be based on the entire tongue.
