Dantou (Erysipelas) caused by food stagnation arises because the Qi of the Spleen and Stomach is not yet sufficient. Excessive intake of milk and food cannot be transformed and transported, leading to heat accumulation internally that reaches the muscle and skin surface.
If caused by stagnation of milk and food, first use Baohe Wan (Harmonizing Pill) to eliminate the stagnation; if constipation occurs, add Rhubarb in appropriate amounts to unblock the bowels. Once the food stagnation has cleared but Dantou still manifests, treat with Qingzhong Jieyu Tang (Clear the Middle and Resolve Depression Decoction). After the pathogenic factor of Dantou is removed but the infant still lacks appetite, use Wuwei Yigong San (Five-Ingredient Extraordinary Effort Powder) to tonify. If fever and thirst occur, or there is poor appetite, use Qiwei Baizhu San (Seven-Ingredient Atractylodes Macrocephala Powder) to tonify. Generally, Dantou caused by rich and greasy diet presents with red halos that spread slowly. If caused by drinking distilled spirits or accidentally ingesting arsenic trioxide, red halos appear all over the body and spread very rapidly. In cases where sores and ulcers erupt with surrounding red halos, if the heat dissipates or pus discharges naturally leading to resolution, all such conditions contraindicate Bianfa (pricking therapy for bloodletting); the primary approach should be to stabilize the interior, avoiding purgative or attacking methods. If spontaneous vomiting and diarrhea occur, they should not be stopped, as these symptoms contain the intent of dispersing pathogens. For cases caused by drinking distilled spirits, drinking one or two cups of cold rice vinegar can resolve the toxicity; this is a miraculous method. If the condition results from the mother consuming excessive roasted, fried, or rich foods, drinking alcohol, taking pungent-hot dry drugs, or suffering liver-Spleen injury due to depression and anger, it should be treated according to the principles for fetal heat toxic sores.
[Zeng's experience] Within one hundred days after birth, or beyond six months of age, an infant may suddenly present with slightly raised red halos on both eyelids, a complexion with bluish-dark hues, evening irritability and crying, or cheeks red like rouge; this indicates latent heat within. There are also cases where the cheeks are not red. Initially, during gestation, the mother suffered severe fright; the fright pathogen injured the fetus, transmitting sequentially, manifesting externally. At initial onset, lesions scatter across the face, resembling water poxes, with slightly red but not robust bases, appearing and disappearing irregularly. Subsequently spreading to the neck, becoming red like cinnabar, it is named Jingdan (Fright Erysipelas). First wash the eyes with Sixian San (Four-Saint Powder), then decoct Baixie San (Hundred-Resolution Powder) together with Wuhe Tang (Five-Harmony Decoction) to resolve fright-heat and erysipelas-toxicity. Niubang Tang (Arctium Decoction), Danggui San (Angelica Powder), Sandisai San (Three-Dispersal Powder), and Huangqin Siwu Tang (Scutellaria Four-Substance Decoction) can all be used for treatment. If Jingdan spreads to the chest and breast area, accompanied by slight phlegm-wheeze and convulsions, urgently disperse heat and extract toxins to prevent internal invasion, which would cause significant harm. Use Wuhe Tang added with Cimicifugae Rhizoma (Shengma), dried Rehmanniae Radix (Sheng Dihuang), fresh ginger, and Juncus effusus (Dengxincao) decocted and administered orally, which will lead to natural resolution. Continue regulating with the aforementioned medicines to prevent other complications. Alternatively, administer Wan'an Yin (Ten-Thousand-Peace Drink).
