General Summary: Various wind pathogens accompanied by heat toxins lurk in the skin; once condensed, they are difficult to remove abruptly. If swelling occurs in the neck and cheeks, the throat and tongue must be protected; internally, wind-heat should be purged, and externally, topical applications are suitable.

The *Huangdi Neijing* (Yellow Emperor's Inner Canon) states: When Ying Qi (Nutritive Qi) fails to circulate properly and rebels within the flesh, carbuncles and swellings arise. The so-called "Wind Toxin" in children arises after convulsions due to wind disorders; wind follows the movement of Qi, and blood is driven by Qi. Toxic vapors accumulate in the skin, flow and condense to form toxic swellings, resulting in hard nodules with red coloration. These often occur between the cheeks or at the roots of the ears and joints. In severe cases, they become carbuncles and furuncles, known as Dun Du Feng (Escaping Wind Poison). It is appropriate to use Dang Gui San (Angelica Decoction) with doubled Zhi Qiao (Aurantium Fructus) and Da Huang (Rhubarb Radix), or such herbs as Zao Jiao Ci (Gleditsia Spine) and Bo He (Mint Leaf). If the nodule is located in the cheeks, treat it using Wu Chi Gao (Black Bean and Aconite Ointment) held in the mouth to dissolve, thereby protecting the throat; externally, apply Fu Du San (Toxin-Dispelling Powder). If swelling arises from broken skin due to falls or injuries, where wind pathogens invade the affected area, it is called Po Xue Shang Feng (Broken Blood Injured Wind); one may administer Shu Feng San (Wind-Dispersing Powder) or Huo Xue San (Blood-Invigorating Powder).

Regarding the condition of Luo Li (Scrofula), the *Neijing* refers to it as He Jie (Knots). Investigating its etiology, as Danxi stated, it results from the accumulation of rich flavors and stagnant Qi, where wind and heat contend with blood to form knots. Those initially appearing behind the ears, under the chin, and down to the neck originate from the Foot-Yangming Stomach Meridian and are called Luo Li; those appearing in the Que Pen (Clavicular Fossa) on the chest side or in the hypochondrium originate from the Hand and Foot-Shaoyang Meridians and are called Ma Dao (Horse Knife). All should be treated according to their underlying causes. Since young children are too weak for acupuncture and moxibustion, only internal medicines and external plasters should be used. However, Jing Yin Yao (Meridian-Guiding Herbs) must be taken to eradicate the root cause to achieve complete success. When taking medicine for this condition, the patient should lie in bed and swallow the medicine ten times a day, then rest quietly afterward. This is because the medicinal power is intended to remain above the diaphragm. If it appears below the throat, wrapping around like a band, it is Chan Hou Feng (Throat-Wrapping Wind); one should take Hua Du Tang (Toxin-Dissolving Decoction) and hold Wu Chi Gao in the mouth to protect the throat. Otherwise, follow the treatment method for Dun Du Feng. If, after taking medicine, the swelling does not stabilize, spreads upward to the top of the head, wanders across the face and eyes, or repeatedly returns to below the throat, presenting as reddish-purple, slightly swollen, with white protrusions in the center, it indicates Yang syndrome transforming into Yin syndrome. Hyperactivity will inevitably cause harm; this is called Chi You Feng Du (Red Wandering Wind-Toxin), which is also difficult to treat.
