Wind-toxin refers to a condition where, following an attack of wind-stroke (convulsions in infants), wind pathogen follows the movement of Qi, and blood is driven by Qi. Toxins accumulate in the skin, flow and knot together to form swelling and toxic masses, resulting in stubborn nodules that are red in color. These typically appear between the cheeks or at the roots of the ears and joints. In severe cases, it develops into carbuncles or boils, known as "Dun Du Feng" (Escaping Wind-Toxin). It is suitable to use Baijie San (Hundred-Resolving Powder), Niubang Tang (Arctostaphylos Decoction), and Danggui San (Angelica Powder) with added Zhiqiao (Bitter Orange) and Dahuang (Rhubarb), decocted in water for oral administration. Alternatively, Zaojiazi (Gleditsia Seed) and Bohe (Mint) can be decocted together, followed by continuous administration of Xionghuang San (Realgar Powder) and Xiaodu Yin (Detoxifying Drink). If the nodule forms in the cheek area, treatment should employ Wu Chi Gao (Black Bean Paste) to protect the throat; externally, Fudu San (Toxin-Removing Powder) and Waixiao San (External-Resolving Powder) should be applied. If caused by falls or trauma damaging the skin, allowing wind pathogen invasion leading to cold-induced toxic swelling, it is called "Po Xue Shang Feng" (Broken Blood Wounded by Wind). One may administer Shufeng San (Wind-Dispersing Powder), Huoxue San (Blood-Invigorating Powder), and Huangqin Siwu Tang (Scutellaria Four-Substance Decoction) for regulation. If the lesion appears below the throat, winding around like a belt, it is "Chan Hou Feng" (Throat-Winding Wind). The *San Yin Fang* records treatments for Wu Hou Feng; this condition is suitable for Huadu Tang (Toxin-Transforming Decoction) and Wu Chi Gao, melted to protect the throat. Medication should absolutely not be applied topically to the external throat. Treatment should follow the internal methods described for "Dun Du Feng." If after taking medicine the swelling dissipates but the pathology persists, or spreads upward to the head and neck, wanders through the face and eyes, and then recurs below the throat appearing reddish-purple, slightly swollen, with white protrusions in the center, this indicates a transformation from Yang syndrome to Yin syndrome. Excessive pathogenic factors will inevitably cause harm, known as "Chi You Feng Du" (Red Roaming Wind-Toxin), which is also difficult to treat.

All accumulation syndromes suffered by infants are due to irregular feeding. Overconsumption of raw, cold, hard, or solid foods overwhelms the Spleen and Stomach's ability to digest and transform, causing food stagnation in the Zhongwan (Middle Jiao/Stomach region). External contraction of wind-cold, or improper covering during eating and sleeping, leads to headache, sallow complexion, fever, slight eyelid swelling, abdominal pain and distension, cold feet with a hot abdomen causing restlessness, mental dullness, loss of appetite, vomiting or hiccups, sour belching, and sour-smelling stools. This is injury caused by old accumulations. If detected within one or two days, first use Baishang Yin (Hundred-Injury Drink) to release the exterior, then administer Danggui San decocted with fresh ginger to warm and move the stagnation. Only then should Wuxi Wan (Rhino Horn Pill) and Liusheng Wan (Six-Sage Pill) be given to strongly promote bowel movement. Finally, use Yunqi San (Qi-Balancing Powder) for regulation and tonification. If overeating damages the Spleen Qi, making it slightly deficient, food becomes difficult to digest, remains, and forms accumulation. When the accumulation deteriorates, it transforms into dysentery with mild abdominal pain. One should first regulate Stomach Qi, then address the accumulation, and finally stop the dysentery, so the root of the disease is eliminated. Use Hezhong San (Harmonize-Middle Powder) to manage deficiency and nourish the Stomach; Sanleng San (Curcuma Powder) and Wuxi Wan to assist the Spleen in transforming accumulation; Chenxiang Binglang Wan (Aucklandia and Areca Nut Pill) and Shouzhong Tang (Maintain-Middle Decoction) to promote appetite and stop dysentery. Raw, cold, and sticky/greasy foods must still be avoided to prevent recurrence. Sometimes, there is frequent passage of green watery stool resembling raw vegetable juice; this is "Jing Ji" (Fright Accumulation) occurring after fright, characterized by irritability, whimpering, and constant signs of anger. Treatment should first resolve the fright, then address the accumulation. To resolve fright, use Wuling San (Five-Ling Powder) or Baijie San; to address accumulation, use Sanleng San, Wuxi Wan, or Sandisai (Three-Dispersing Powder), mixed with fried Shenqu (Medicated Leaven) and fresh ginger, decocted in water for administration. Xingpi San (Spleen-Awakening Powder) and Chenxiang Binglang Wan can calm fright and transform accumulation, strengthen Qi, harmonize the Stomach, while regulating cold milk intake, leading to natural recovery.
