CORE DEFINITION

Insufficiency of yin fluid fails to restrain yang qi, leading to relative hyperactivity of yang. This is a common pathogenesis in hypertension and hyperthyroidism.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Imbalance due to loss of weight. It is not that yang qi is truly excessive (excess fire), but that yin qi is insufficient (unable to restrain). Do not merely purge fire (which would harm the vital qi); instead, strengthen the yin side (nourish yin), and the seesaw will naturally balance.

Anchor fast decisions

Deficiency of yin fluid leads to loss of restraint on yang, which becomes hyperactive upward, manifesting as dizziness, flushed face, irritability, insomnia, and other signs of upper excess and lower deficiency.
