Resulting in coma. By morning, when Yang Qi is vigorous and Qi ascends, consciousness clears. This resembles Heat entering the Blood Chamber (Re Ru Xue Shi), but the etiology and treatment methods are vastly different. The tongue coating, whether yellow or white, must be accompanied by a slippery and greasy texture. It is appropriate to use acrid-aromatic and bitter-warm agents to first open up and expel damp-turbidity, allowing the Qi mechanism of the Triple Burner (San Jiao) to flow freely and the pathogenic Heat to vent outward. Subsequently, using acrid-cool methods for clearing will lead to spontaneous recovery. If treated improperly, it may transform into malaria or dysentery in mild cases, and prove fatal in severe cases. These are all syndromes that appear like obstruction (Bi) but are not true obstructions, representing a state of impending closure. They are specifically highlighted here for differentiation, so that later learners do not go astray and thereby harm patients.
