5. For exogenous cold (Shanghan) presenting with anhidrosis and excess pathogenic factors, as well as for alcohol-induced diseases manifesting like wind-stroke, Guizhi Tang (Cinnamon Twig Decoction) must not be administered. If mistakenly given to exogenous cold, it leads to persistent vomiting; if mistakenly given to alcohol-induced disease, it causes damp-heat to brew internally, damaging the Ying level (Nutritive Level) and resulting in hematemesis or purulent stool. For patients with a slow pulse at the Chi position (cun-kou pulse location), administering Mahuang Tang (Ephedra Decoction) induces continuous sweating known as "leaking sweat" (Louhan), accompanied by aversion to wind, stiffness of the four limbs, and difficulty in urination. For patients with a faint pulse and spontaneous sweating with aversion to wind, administering Da Qinglong Tang (Major Green Dragon Decoction) leads to cold extremities, palpitations with fright, dizziness, persistent fever, muscle twitching, and severe tremors where the patient feels unable to rise and desires to fall to the ground. In such cases of adverse reactions due to misprescription, Guizhi Jia Fuzi Tang (Cinnamon Twig Decoction plus Aconite) should be used to rescue from the adverse reaction, or Zhenwu Tang (True Warrior Decoction) should be employed to cure the condition.

[Annotation] "Exogenous cold" refers to the excess syndrome of exogenous cold characterized by anhidrosis. "Alcohol-induced disease" refers to conditions resembling wind-stroke caused by excessive alcohol consumption. "Guizhi Tang must not be given" means that Guizhi Tang is contraindicated in both scenarios. Mistakenly using Guizhi Tang for exogenous cold further consolidates the exterior Qi while causing interior Qi to rebel, leading to persistent vomiting. Mistakenly using it for alcohol-induced disease causes damp-heat to ferment internally, damaging the Ying level and resulting in hematemesis or pus in the stool. These are adverse reactions from the misuse of Guizhi Tang; treatment should follow the specific adverse manifestations.

"Chi slow" refers to a slow pulse at the Chi position in exogenous cold. "Taking Mahuang" refers to the administration of Mahuang Tang for diaphoresis, which results in unceasing sweating, termed "leaking sweat." "Limb stiffness" denotes tetany or contracture of the four limbs. "Difficulty in urination" implies oliguria and dysuria. Although exogenous cold typically requires Mahuang Tang for diaphoresis, a slow pulse at the Chi position indicates deficiency of Ying Qi, making diaphoresis contraindicated. Mistaken diaphoresis leads to adverse reactions such as leaking sweat, aversion to wind, limb stiffness, and urinary difficulty. In such cases, Guizhi Jia Fuzi Tang should be used to rescue from the adverse reaction.

"Faint" refers to a faint pulse in the context of Da Qinglong Tang syndrome. "Sweating with wind aversion" refers to spontaneous sweating and aversion to wind in Da Qinglong Tang syndrome. The pulse for Da Qinglong Tang should not be floating and tight; if it is floating, moderate, and faint with accompanying sweating, the indications for Da Qinglong Tang are not fully present. Mistakenly inducing diaphoresis with Da Qinglong Tang causes cold extremities, muscle twitching with fright, palpitations, dizziness, persistent fever, and body muscle tremors. "Trembling and desiring to fall to the ground" describes incessant shaking and inability to stand, feeling as though collapsing. These are adverse reactions from the misuse of Da Qinglong Tang for diaphoresis; Zhenwu Tang should be used to rescue from the adverse reaction. See the Taiyang Chapter for details.
