CORE DEFINITION

The main meridians branch into collaterals, which further branch into minute collaterals (similar to capillaries). They spread throughout the body and are the final destination of chronic diseases entering the collaterals.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Terminal logistics. The patency of large vessels does not guarantee adequate tissue blood supply. Red streaks on the skin or spider nevi indicate blockage of minute collaterals. Treatment requires 'pricking collaterals to release blood', directly unloading at the terminal.

In the meridian system, the branching sequence is meridian → collateral → minute collateral. Minute collaterals are the finest and most numerous, covering the body surface, serving as the terminal for qi and blood distribution. Chronic diseases enter the collaterals, and terminal stasis is the final outcome of chronic conditions, requiring 'pricking collaterals' at the terminal to unblock.
