Taiyang wind-stroke with a floating-tight pulse, fever and aversion to cold, body pain, absence of sweating, and irritability should be treated with Da Qing Long Tang (Cyan Dragon Decoction) (This represents the pathway for Taiyang pathogenic factors to transmit to Yangming). If the pulse is faint and weak, with sweating and aversion to wind, it must not be administered. Administration would result in cold extremities (Jue Ni), twitching of sinews, and quivering of muscles, which constitutes a therapeutic error. It should be rescued with Zhen Wu Tang (True Warrior Decoction) (Formula found in Shaoyin Chapter 19; this represents the pathway for Taiyang pathogenic factors to transmit to Shaoyin).

The nature of Ying (Nutritive Qi) is to expand and disperse, whereas the nature of Cold is to consolidate and astringe. In Cold damage (Shang Han), Ying Qi desires to disperse but is closed by Cold, resulting in a tight pulse and absence of sweating. The nature of Wei (Defensive Qi) is to gather and close, whereas the nature of Wind is to vent and discharge. In wind-strike, Wei Qi desires to close but is discharged by Wind, resulting in a slow pulse and presence of sweating.

Taiyang wind-stroke presenting with a tight pulse, body pain, alternating chills and fever, and absence of sweating shares identical pulse and symptom patterns with Cold damage. This occurs because Wei Yang is inherently vigorous, causing Qi stagnation that prevents Blood from venting. When Wei Qi is obstructed and closed, Ying Qi becomes severely郁 (stagnant) and generates heat, thus manifesting as irritability. In Da Qing Long Tang, Gan Cao (Licorice Root) and Da Zao (Jujube Fruit) tonify Spleen essence; Sheng Jiang (Fresh Ginger) and Xing Ren (Apricot Seed) descend Lung Qi; Ma Huang (Ephedra Herb) and Gui Zhi (Cinnamon Twig) vent the stagnation and closure of Ying and Wei; Shi Gao (Gypsum Fibrosum) clears the irritability of Shen (Spirit). Generally, if Qi desires to close while Blood desires to vent, and Blood is strong while Qi cannot close, Ying will vent and sweating will occur. If Qi is strong while Blood cannot vent, Ying will close and sweating will not occur. When Ying-heat is internally stagnant with no external outlet, symptoms such as tight pulse, body pain, alternating chills and fever, absence of sweating, and irritability arise. Subsequent conditions such as Bai Hu Tang (White Tiger Decoction) syndrome or Cheng Qi Tang (Order the Qi Decoction) syndrome all result from the internal transmission of channel heat. If dispersed early with Da Qing Long Tang, internal heat would not generate.

If the pulse is faint and weak, accompanied by sweating and aversion to wind, these are the original pulse and symptoms of wind-strike. At this stage, Yang is deficient and Yin is flourishing, so this formula must not be taken. Taking it would cause excessive sweating leading to loss of Yang, resulting in cold extremities, twitching of sinews, and quivering of muscles, causing significant harm. Limbs derive their Qi from the Spleen and Stomach; when Yang is lost and Earth energy fails, limbs lose warmth and become cold. Sinews are governed by the Liver; Liver Wood is born from Kidney Water and grows on Spleen Earth. Cold Water and damp Earth cause Wood stagnation and Wind agitation, leading to trembling sinews and quivering flesh. In Zhen Wu Tang, Fu Ling (Poria) and Bai Zhu (Atractylodes Rhizome) dry dampness and strengthen Earth to drain damp; Fu Zi (Prepared Aconite Root) warms meridians and expels cold; Shao Yao (Peony Root) clears the Lungs and extinguishes Wind.

Ma Huang (Ephedrae Herba, 6 liang), Gui Zhi (Cinnamomi Ramulus, 2 liang), Gan Cao (Glycyrrhizae Radix et Rhizoma Praeparata cum Melle, 2 liang, honey-fried), Da Zao (Ziziphi Jujubae Fructus, 12 pieces), Sheng Jiang (Zingiberis Rhizoma Recens, 3 liang), Xing Ren (Armeniacae Semen Amarum, 50 pieces), Shi Gao (Gypsi Fibrosum, one piece the size of an egg, crushed).

Take the above seven ingredients, add nine sheng of water, first boil Ma Huang until reduced by two sheng, remove the foam on the surface, then add the remaining herbs. Boil until three sheng remain. Take one sheng warm. Aim for slight sweating. If sweating is excessive, apply warm powder to the body (Mu Li Fen/Ostreae Concha Powder can stop generalized sweating). If sweating occurs after the first dose, stop taking the remaining medicine. Excessive sweating may lead to Yang loss and subsequent deficiency, manifesting as aversion to wind, irritability, and inability to sleep.
