(In the category of Cold Damage, among various miscellaneous diseases, only children are prone to these conditions, and their treatment differs from that of adults.)

The syndrome of "夾惊" (Concomitant Fright) arises when pathogenic heat invades the Heart. Extreme heat generates wind, causing trembling of the hands and feet, mental confusion, redness of the face while suckling milk, phlegm obstruction with wheezing, a sawing sound in the throat, locked jaws, and upward deviation of the eyes, thereby transforming into a fright condition. If phlegm-heat accumulates in the Upper Jiao and disrupts horizontally, emesis may be employed immediately. If pathogens occupy all three Jiaos, purgation may be employed immediately. Treatment should cease once heat subsides and the disease resolves; the full dose should not necessarily be consumed. This is because emesis damages Qi, and Qi deficiency leads to palpitations; purgation depletes Blood, and Blood deficiency leads to fright. Therefore, many cases transform into Slow Fright after excessive medication.

The syndrome of "夾食" (Concomitant Food Stagnation) occurs before, during, or after the onset of illness. For instance, if one contracts an external pathogen after eating, leading to stagnation, chest discomfort, abdominal distension, sour-smelling stools, abdominal pain, and rapid breathing, this results from food intake prior to the onset of illness. If Stomach Qi is weak and pathogenic heat lies dormant, causing increased appetite; or if Stomach Qi is not yet deficient and struggles against the pathogen, resulting in vomiting, this case is easy to treat. If the Spleen and Stomach are weak, unable to digest food nor struggle against the pathogen, leading to heat binding in the chest and diaphragm, this results from dietary indiscretion during the onset of illness due to Spleen-Stomach deficiency. If, after slight recovery, one eats without restraint, leading to stagnation and fever, this is called "Food Relapse," resulting from dietary indiscretion after the illness. Treatment should follow the pattern of excess or deficiency: for excess patterns, resolving stagnation is primary; for deficiency patterns, nourishing the Stomach is assisted.

Rashes (Ban) arise from Warm Toxin, Heat Toxin, or Rotting Stomach. Warm Toxin refers to cold contracted in winter, which erupts in spring when Yang Qi contends with Yin Qi. Heat Toxin refers to summer-heat latent in the Stomach, which erupts upon exposure to cold. Rotting Stomach occurs either from erroneous purgation allowing heat to enter the Stomach via deficiency, or from failure to purge, preventing heat from venting externally, so that toxic vapors penetrate deeply into the Stomach. Thus, rashes represent toxin. Toxin is a state of aberrancy, extreme deviation of Yin or Yang. Externally caused by the interaction of the Six Qi, internal heat-toxin steams within the Stomach. Since the Stomach governs muscles, extreme heat injures Blood, creating interior excess and exterior deficiency. Consequently, spots resembling bites appear all over the body. Red and bright spots indicate survival; purple-black spots indicate death, due to extreme heat causing rotting of the Stomach. Dry tongue coating and cracked lips indicate incurability. Treatment should focus on clearing heat and detoxifying. Exterior-releasing drugs for sweating must not be used, as exterior deficiency with interior excess means sweating will further open the pores, worsening the rash. In cases of Yin-pattern rash, it may result from Qi deficiency of the Middle Jiao after sweating, vomiting, or purging; or from depletion of True Yang due to sexual activity; or from excessive use of cold medicines, forming a Yin pattern where cold lurks below, forcing rootless, unanchored fire to ascend and steam the Lungs and Stomach, producing pale-red spots faintly visible under the skin. This differs from Yang-pattern rashes, which are purple-red. This indicates extreme Stomach Qi deficiency; administering cold medicines would lead to immediate danger. Wu Hegao stated: Using Ginseng, Cinnamon Twig, and Aconite to treat rashes is a variation in therapeutic method. Physicians who do not understand flexibility cannot discuss this. If itching and plaques form due to Wind-Heat carrying Phlegm, this is a mild case, curable with detoxifying and acrid-dispersing herbs.

Internal Injury Rash arises from insufficiency of Original Qi due to internal injury. Due to dual deficiency of Qi and Blood, patients also experience body pain, irritability, and fever, but differ in having a large and empty pulse, reluctance to speak or move, fatigue, and spontaneous sweating. Treating this erroneously as an exterior excess condition leads to immediate peril. Rapid administration of Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) allows for deep sleep, cessation of fever, and recovery. Zhu Danxi said: Internal injury rash indicates extreme Stomach Qi deficiency, with Fire roaming outside the body. It should be treated by tonification to descend the Fire. Dajianzhong Tang (Greatly Build the Middle Decoction) is best, containing Ren Shen (Ginseng), [missing character, likely Bai Zhu], Dang Gui (Angelica Sinensis), Bai Shao (White Peony Root), Zhi Gan Cao (Prepared Licorice), Ban Xia (Pinellia), Gui Zhi (Cinnamon Twig), and Fu Zi (Aconite), decocted with Ginger and Jujube. If latent Yin exists internally and cold medicines are mistakenly taken, forcing deficient Yang to float outward, forming Yin Rash, the pulse may be surging and large but empty upon pressure, or extremities may be cold beyond elbows and knees. First, use Pao Jiang Lizhong Tang (Baked Ginger Regulate the Middle Decoction) to restore Yang, then treat according to symptoms. If ineffective, add Fu Zi (Aconite).
