You Yong (Deep Abscess) arises seven cun above the umbilicus. Initially, it resembles a millet grain, gradually increasing to a diffuse swelling with pain, shaped like a goose egg; in severe cases, it becomes hard and causes pulling pain to the chest and hypochondrium. This condition results from excessive consumption of rich and greasy foods, combined with worry and thought leading to Qi stagnation, intestinal and stomach obstruction, and the accumulation of fire-toxin, manifesting from the interior to the exterior. In the early stage, Shen Shou Wei Sheng Tang is administered; after ulceration, tonifying and expelling methods are used immediately.

He Yong (Bright Abscess) arises three cun above the umbilicus, belonging to the Jianli acupoint (Jianli, CV11) of the Ren Mai (Conception Vessel). It is formed by the condensation of fire due to the stagnation of the Seven Emotions. Initially, it is like a millet grain, accompanied by both itching and pain, with rapid swelling, alternating chills and fever, and in severe cases, vomiting and hiccups, with pulling pain at the umbilicus. If the initial swelling is slightly red, with a pointed apex and constricted base, gradually turning crimson, Huo Ming Yin (Life-Saving Decoction) is used to dissipate it; after suppuration, Tuo Li Xiao Du San (Interior-Tonifying and Toxin-Expelling Powder) is applied; once ulcerated, Shen Nei Tuo San (Ginseng Interior-Tonifying and Expelling Powder) is suitable.

Chong Ju (Thrusting Carbuncle), also known as Zhong Fa Ju (Central-Erupting Carbuncle), arises two cun above the umbilicus, corresponding to the Xiawan acupoint (Xiawan, CV10) of the Ren Mai. It is caused by excessive Heart Fire flowing into the Kidney Meridian. If the swelling is high, red, and the pus is thick, it is easy to heal; if the swelling is flat, black, accompanied by abdominal distension and nausea, thin pus, internal Kidney pain, uncontrolled diarrhea, delirium, and fixed gaze, death ensues; if it ulcerates and fails to heal for a long time, death also ensues. All these conditions belong to Deficiency. The method should employ major tonifying agents. If the patient can tolerate tonification, they will not die.

Xue Lizhai stated: The breast belongs to the Foot-Yangming Stomach Meridian, and the nipple belongs to the Foot-Jueyin Liver Meridian. In men, sexual excess or anger injures the Liver and Kidneys; in women, overthinking and depression damage the Liver and Spleen; both can lead to sores. However, sores in the breast vary. One type presents as nodules in the breast, shaped like pills or eggs, without pain, chills, or fever, with unchanged skin color; the nodules fluctuate in size with emotions of joy or anger. This is named Ru Pi (Breast Lump). This is indeed caused by the stagnation and accumulation of Liver Qi; regarding it as Phlegm-Qi stagnation is incorrect. Since the breast belongs to the Yangming, why are nodules in the breast attributed to the Liver rather than the Yangming? Because Yangming Earth most fears Jueyin Wood. When Liver Qi is stagnant, the Stomach, seeing the stagnation of Wood, fears being overcome, thus lying dormant and not rising, with Qi不敢 (daring not) to relax. As Liver Qi does not relax, hardness and swelling form; as Stomach Qi dares not relax, signs of fear appear. The absence of pain and redness precisely reflects this fear. The treatment need not address the Stomach; only by treating the Liver will the swelling subside naturally. Xiaoyao San (Free and Easy Wanderer Powder) with ginger and mint removed, plus Gua Lou (Trichosanthes Fruit), Ban Xia (Pinellia Tuber), and Ren Shen (Ginseng Root) is the main prescription (This formula specifically resolves Liver stagnation; once the Liver is resolved, the Stomach's lack of relaxation naturally soothes, largely because Gua Lou and Ban Xia specifically treat accumulated Phlegm in the chest; once Phlegm is gone, swelling is easier to eliminate).

Another type presents as nodules in the breast that initially do not hurt, but later cause dull pain, or systemic chills and fever, gradually forming pus and ulcerating. This is named Ru Tan (Breast Phlegm). It may also be caused by Qi stagnation in the Liver Meridian or by the steaming and stagnation of Phlegm-Qi in the Stomach Meridian. In medication that soothes the Liver, one must add Bei Mu (Fritillaria Bulb), Ban Xia, and Gua Lou to treat Phlegm; thus, before suppuration, it can be dissipated, and after ulceration, tonifying Qi and Blood is necessary for wound closure.

Among breast sores that are incurable is Ru Yan (Breast Rock/Cancer). Ru Yan arises from depression and overthinking, with desires unfulfilled, causing Liver and Spleen Qi to rebel, leading to meridian obstruction and nodule formation. Initially small as a bean, it gradually grows like a chess piece, without redness, swelling, pain, or itching. Over half a year to a year, or two to three years, it gradually enlarges, then begins to hurt, with pain having no relief. Later, the swelling resembles piled chestnuts or an inverted bowl, purple with foul odor, gradually ulcerating. Deep ulcers resemble rock caves, protruding ones resemble floating lotuses. Pain radiates to the heart, bleeding has a foul odor, and there is no pus. At this stage, the Five Zang Organs are all exhausted, leading to the failure of the Four Extremities, which is incurable. Those who contract this disease die hundred percent. If one can maintain a clear mind and quiet nourishment, without attachments or obstructions, and does not force treatment, life may be prolonged. Jia Wei Xiaoyao San (Modified Free and Easy Wanderer Powder), Gui Pi Tang (Restore the Spleen Decoction), or Yi Qi Yang Ying Tang (Tonify Qi and Nourish Ying Decoction) should be used. In this condition, with ulceration and constitutional weakness, there are cases where blood spurts from the wound, leading to immediate death, similar to Shi Ying Syndrome (Loss of Camp/Incurable Cancer).
