Yang Shiying stated: Manpi Feng (Slow Spleen Wind) arises after Man Jing Feng (Slow Convulsion), where vomiting and diarrhea damage the spleen. The disease has progressed to its extreme, ultimately returning to a state of deficiency, affecting only the spleen; hence it is called Spleen Wind. The wind cannot be forcibly expelled, and convulsions are difficult to treat directly. It is merely that phlegm and saliva stagnate within the spleen, with deficient heat fluctuating. If the eyes are closed, it indicates spleen exhaustion, qi deficiency, and spirit confusion. If the eyes are seen closed, it is Manpi Feng. In Man Jing Feng, the eyes remain half-open and half-closed, indicating that yin qi is abundant and has transmitted into the zang organs, while yang qi is already depleted. Since the spleen meridian belongs to yin, the pathogen enters the spleen sequentially; thus, it is termed the syndrome of Manpi Feng. If Man Jing Feng presents with eyes half-open and half-closed, one should preemptively manage it according to Manpi Feng protocols. The manifestations of Manpi Feng include a bluish complexion, sweating on the forehead, a short tongue, drooping head, eyes closed and unable to open, shaking the head and protruding the tongue during sleep, frequent vomiting of foul-smelling substances, locked jaw with teeth grinding, slight twitching of the hands and feet that cannot retract, or cold body temperature, or warm body but cold limbs. The pulse is deep and faint, indicating extreme abundance of yin qi and extreme deficiency of stomach qi. Only one or two out of ten may be saved. This likely results from the transmission of Man Jing Feng; Hei Fu Tang (Black Aconite Decoction) should be used for rescue. Sheng Fuzi Sijunzi Tang (Raw Aconite Four Gentlemen Decoction) and Xie Fu San (Scorpion and Aconite Powder) are also applicable. Medication for Manpi Feng is a last resort. Its critical nature is like a lamp running out of oil, gradually dimming. Qian Yi (Qian Shi) prescribed mixing Jin Ye Dan (Golden Liquid Pill) and Qingzhou Bai Wan Zi (Qingzhou White Pills) in equal parts, ground uniformly, and administered with rice water and mint decoction, one qian or 1.5 qian. This aims to intercept wind-yang.

Zhang Yunqi stated: Although the child's head feels hot, if the eyeballs are blue-white and the feet are cold; although the head feels hot, if there is abdominal distension and cold feet; although the head feels hot, if there is diarrhea and cold feet; although the head feels hot, if there is vomiting and cold feet; although the head feels hot, if there is thirst and cold feet. When any of these five symptoms present with convulsions, it is named Manpi Feng. Immediately administer Bupi Yizhen Tang (Spleen-Supplementing and True-Yang-Replenishing Decoction) with one whole Scorpion (Quanxie), or Quanchi Guanyin San (Whole Scorpion Guanyin Powder).

Tan Shusheng stated: Manpi Feng is also known as Xu Feng (Deficiency Wind). After vomiting or diarrhea, if the child’s complexion is sallow and deficient, and fever arises from deficiency, accompanied by initial signs of head shaking, oblique gazing, drowsiness, forehead sweating, sticky sweat on the body, and a low, small, and anxious voice, this is the syndrome of Spleen Wind. It does not necessarily have to result from the sequential transmission of Ji Jing Feng (Acute Convulsion) or Man Jing Feng. Manpi Feng occurs only through transmission via vomiting, diarrhea, food accumulation, or dysentery. The symptom changes are extremely rapid, and the deficiency progresses even faster. Treatment must follow a gradual and mild approach; there is no principle of rapid cure. Regulate the spleen and nourish the stomach without overdosing.

Shen Jin'ao commented: According to Tang Shi’s method, for cases where vomiting and diarrhea lead to Xu Feng and Manpi, first use Du Ming San (Life-Seizing Powder) and Qingzhou Bai Wan Zi powder, decocted into a thin paste, mixed with honey, to induce expectoration of phlegm. After the phlegm is controlled, administer Xing Pi San (Awaken Spleen Powder).
