[Formula Song] Huzi Du (a carbuncle-like disease occurring below the chin) arises in the submental region, caused by accumulated heat in the Stomach and Kidney meridians invading the Ren Mai (Conception Vessel). Carbuncles present with redness, swelling, heat, and pain, are prone to suppuration, and heal easily; Jū (deep-seated abscesses) present with hardness, pain accompanied by numbness and itching, falling under the category of Ding (hard chancre/furuncle).
[Note] This toxic condition is also known as Kai Yong (Cough Abscess), characterized by swelling, pain, redness, and heat, which suppurates quickly and is easy to treat; it is also known as Chengjiang Ju (Chengjiang Deep Abscess), characterized by hardness, swelling, and pain, which suppurates slowly and is difficult to treat. If the root is deep, the shape is small like a bean, accompanied by severe numbness, itching, and pain, along with aversion to cold, fever, mental restlessness, and vomiting, it is classified as Ding (Hard Chancre/Furuncle) and should be treated according to Ding protocols. All these conditions result from excessive consumption of roasted or fried foods, leading to accumulated heat in the Stomach and Kidney meridians attacking upward into the Ren Mai. In the initial stage of both Carbuncle and Jū syndromes, it is appropriate to administer Xianfang Huoming Yin (Immortal Life Elixir Decoction) added with Shengma (Cimicifugae Rhizoma) and Jiegeng (Platycodonis Radix) to dissipate the swelling. If constipation, dry cracked lips, and extreme thirst are present, Neishu Huanglian Tang (Internal Purging Coptis Decoction) should be used to clear heat. For other internal and external treatment methods, refer to the sections on Carbuncles and Jū, Swollen Sores, and Ulcerated Sores. If initial symptoms resemble Ding (numbness and itching), follow the Ding treatment protocols.
Formulas: Xianfang Huoming Yin (Immortal Life Elixir Decoction), Neishu Huanglian Tang (Internal Purging Coptis Decoction) (both see section on Swollen Sores)
[Formula Song] Yanwo Chuang (Swallow's Nest Sore, a dermatological condition below the chin) occurs in the submental region, resembling clusters of millet seeds or beans, accompanied by itching, heat, and pain. Its appearance resembles Huangshui Chuang (Yellow Water Sore) and tends to rupture easily; this syndrome originates from Damp-Heat pathogenic factors.
[Note] This condition arises in the submental region, commonly known as "Sheep Beard Sore." Initially, lesions are small like millet seeds or large like beans, appearing red, hot, itchy, and slightly painful. Upon rupture, they exude yellow fluid, resembling Huangshui Chuang (Yellow Water Sore), spreading into patches but with clustered nodules. It is caused by Damp-Heat in the Spleen and Stomach. It is appropriate to take Qinlian Pingwei Tang (Coptis and Coptis-Pingwei Decoction) and externally apply Biyu San (Jade Powder) for effective results.
Formula: Qinlian Pingwei Tang (Coptis and Coptis-Pingwei Decoction)
Composition: Huangqin (Scutellariae Radix, 1.5 qian), Huanglian (Coptidis Rhizoma, 1 qian), Houpo (Magnoliae Officinalis Cortex, stir-fried with ginger, 1 qian), Cangzhu (Atractylodis Rhizoma, stir-fried, 2 qian), Gancao (Glycyrrhizae Radix et Rhizoma, raw, 0.5 qian), Chenpi (Citri Reticulatae Pericarpium, 1 qian).
Add two zhong of water and one slice of ginger, decoct until reduced to eight fen, and take after meals.
[Formula Song] Qinlian Pingwei Tang treats Yanwo Chuang (Swallow's Nest Sore); clearing dampness and heat yields better results. Ginger-fried Houpo combined with Cangzhu and Gancao, decocted together with Chenpi and guided by ginger.
Another Formula: Biyu San (Jade Powder)
Composition: Huangbai (Phellodendri Cortex) powder, Hongzaorou (Ziziphi Jujubae Fructus flesh, charred to retain efficacy, each 5 qian).
Grind together into an extremely fine powder, mix with sesame oil, and apply topically to the affected area.
[Formula Song] Apply Biyu San (Jade Powder) to Yanwo Chuang (Swallow's Nest Sore) for red nodules and yellow exudate; mixing charred jujube flesh with Phellodendri powder and sesame oil constitutes a formula for relieving pain, stopping itching, and draining dampness.
