1. Sang Ju Yin Qiao Class Formulas

Sang Ju Yin and Yin Qiao San both originate from "Wen Bing Tiao Bian," pioneering the use of pungent-cool exterior-releasing herbs and compensating for the lack of pungent-warm exterior-releasing herbs in "Shang Han Lun." They demonstrate remarkable clinical efficacy and are highly praised by physicians. Sang Ju Yin consists of eight medicinal ingredients: mulberry leaves, chrysanthemum, forsythia, apricot kernel, platycodon, reed root, peppermint, and licorice, primarily treating wind-heat exterior syndrome, headache, fever with chills (more heat than cold), thirst, sore throat, and cough. Modern medicine believes this formula is suitable for acute pharyngitis caused by Gram-positive cocci and various non-toxic upper respiratory infections, including lobar pneumonia, bronchial pneumonia, and acute/chronic bronchitis. It is particularly effective for high fevers in children with upper respiratory infections. Yin Qiao San consists of schizonepeta spike, platycodon, honeysuckle, forsythia, honeysuckle, bamboo leaves, fermented soybeans, cowherb seeds, licorice, and reed root, mainly treating wind-heat exterior syndrome accompanied by sore throat, with symptoms such as headache, fever with chills (more heat than cold), thirst, and sore throat. This formula has slightly broader indications than Sang Ju Yin and stronger heat-clearing and detoxifying effects. From a Western medical perspective, in addition to treating acute tonsillitis, it is also effective against all purulent bacterial infections throughout the body. Wu Wei Xiao Du Yin (from "Yi Zong Jin Jian") consists of five medicinal ingredients: honeysuckle, wild chrysanthemum, dandelion, purple flowered violet, and purple-backed daylily, primarily treating carbuncles, sores, and various purulent infections. Although only five ingredients are used, the therapeutic effect is excellent. Xian Fang Huo Ming Yin (from "Wai Ke Fa Hui") consists of pangolin scales, trichosanthes root, licorice, frankincense, angelica root, red peony, fritillaria bulb, ledebouria, myrrh, soapberry spines, angelica root, tangerine peel, and honeysuckle, mainly treating carbuncles, boils, and abscesses, whether the pus has not yet formed or has already formed but not ruptured. Qing Wen Bai Du Yin (from "Yi Zhen Yi De") consists of coptis, scutellaria, gardenia, cortex moutan, rehmannia, forsythia, licorice, raw rehmannia, rhino horn, red peony, anemarrhena, platycodon, gypsum, bamboo leaves, and other ingredients, primarily treating cases where pathogenic heat penetrates deeply, causing both qi and blood to be scorched. Clinical symptoms include high fever, intense thirst, profuse sweating, confusion, agitation, delirium, toxic rash, hematemesis, epistaxis, and hematochezia. From a modern medical perspective, this formula is suitable for sepsis caused by various infections, which in traditional Chinese medicine corresponds to pathogenic heat penetrating deeply—essentially referring to sepsis in Western medicine. Pu Ji Xiao Du Yin (Li Dongyuan) consists of coptis, scutellaria, indigo root, black ginseng, burdock seed, horse chestnut, forsythia, tangerine peel, licorice, silkworm pupa, bupleurum, peppermint, platycodon, and cimicifuga, mainly treating epidemic parotitis, large-head plague, facial erysipelas, and throat swelling caused by heat toxicity attacking upward.
