    Ling Shu Ch. 75, On Piercing to Regulate True and Evil Qi, recommends this point as part of the "Undressing" treatment. Its indications are when there is a surplus of Yang and insufficiency of Yin Qi causing Heat in the interior and exterior. The two heats combine to become hot like burning coal and they cannot bear to have clothes touch the skin or to lie on a mattress, the pores are closed and there is no sweating, the tongue is scorched, the lips are desiccated, the flesh dries up, the throat is parched and they cannot tell good from bad food. It is treated by removing the Heat from this point, Tianfu Lu-3 and Dazhu Bl-11, then supplementing the Taiyin channels of hand and foot, Lung and Spleen, to diminish the sweat. Presumably the initial piercings are supposed to induce the sweat or this contradicts the earlier symptom of the pores being closed and the sweat not leaving.
