（又名鬼饭疙瘩，俗名风乘疙瘩。）
初起时皮肤瘙痒，随后出现扁平的疙瘩，形状像豆瓣，堆积成片，这是由于出汗后受风，或夜间受露水侵袭，风湿邪气相互搏结而发病。
外用百部浸泡于烧酒中，用蓝布蘸取擦拭患处。
服用荆防败毒散（通用方剂四）。
此症多见于小儿，是因为感受了四季不正之气，郁结在肌肤无法发散，发作时形成大小不一的青紫色斑点，颜色像葡萄，头面及全身各处都可能发生。伴有身体发热、口渴者，以羚角化斑汤为主治；不口渴且倦怠乏力者，以补中益气汤加生地黄为主治。

肌肤初起呈现红色晕圈，由小逐渐扩大，浮肿成片，或者隆起堆积如粟米状，伴有发热、疼痛与瘙痒并存，病位游走不定。红色的称为赤游丹。
先服用消风饮，白色的继服补中益气汤，并增加防风、蝉蜕、苏叶、鲜首乌；外用广胶炖融化后涂抹，涂至痊愈。
若病邪游走进入胸腹部，属于逆证。忌食猪、羊、鸡、鹅、鱼腥等一切动风燥血的食物。

In summer, sweat moistens and obstructs the hair follicles (pores), causing prickly heat (commonly known as prickly heat) resembling a rash. Use one liang of mung bean powder, five qian of talcum stone, and two qian of calomel, grind them evenly together, dip soft silk cloth in the mixture, and pat it onto the affected area; or apply finely ground earth from the east wall.
(Also known as "Ghost Rice Bumps," commonly called "Wind-Struck Bumps.")
Initially, the skin itches, followed by the appearance of flat bumps resembling broad beans, accumulating into patches. This occurs due to wind exposure after sweating or dew exposure at night, where wind-dampness pathogens combine to cause the disease.
Externally, soak *Stemona Root* (Bai Bu) in distilled liquor, dip blue cloth in it, and rub the affected area.
Administer Jingfang Baidu San (General Formula No. 4).
This condition mostly occurs in children, caused by contracting abnormal qi of the four seasons, which stagnates in the skin and fails to disperse. It manifests as greenish-purple spots of varying sizes, resembling grapes, appearing anywhere on the head, face, and body. For cases with fever and thirst, Lingjiao Huaban Tang is the primary treatment; for cases without thirst but with fatigue, Buzhong Yiqi Tang added with Rehmanniae Radix (Sheng Di) is the primary treatment.
1. If pathogenic toxins transmit to the stomach, causing rotting and bleeding of the gums, internally administer Lingjiao Huaban Tang removing Atractylodis Rhizoma (Cang Zhu), adding Cimicifugae Rhizoma (Sheng Ma) and Puerariae Radix (Ge Gen), and externally apply Zhenzhu San.
Lingjiao Huaban Tang
Antelope Horn (Ba Fen) Gypsum (San Qian) Anemarrhena Rhizome (Zhi Mu) Ginseng (Ren Shen) Licorice Root (Gan Cao) Scrophularia Root (Yuan Shen) Saposhnikovia Root (Fang Feng) Atractylodis Rhizoma (Cang Zhu) Bubble Tea Fruit (Niu Bang Zi) (Each Yi Qian)
Add ten slices of light bamboo leaves, decoct in water until six fen remains, take far from meals.
Buzhong Yiqi Tang (General Formula No. 30).
Zhenzhu San (See Throat Section: Throat Abscess).
The skin initially shows rosy halos that gradually enlarge, becoming edematous and patchy, or elevated and piled like millet grains, accompanied by fever, pain, and itching, with migratory and indefinite locations. Red ones are called Chi You Dan (Red Migratory Erysipelas).
First administer Xiaofeng Yin; for white ones, subsequently administer Buzhong Yiqi Tang increased with Saposhnikovia Root (Fang Feng), Cicada Slough (Chan Yi), Perilla Leaf (Su Ye), and fresh Polygonum Multiflorum Root (Xian Shou Wu); externally, all cases use gelatin (Guang Jiao) melted by steaming for application until healed.
If the pathogen migrates into the chest and abdomen, it is a adverse prognosis. Avoid pork, mutton, chicken, goose, fishy smells, and all foods that stir wind and dry blood.
1. Pediatric Chi You Dan is caused by toxin received in the womb, often starting on the legs with red swelling in patches; if it migrates over the whole body, death ensues. The treatment method must first use fine porcelain edges for scarification (bloodletting); those who delay and refuse scarification cannot be saved. Take medicines as before.
