Xie Yong (Abscess of the Hypochondrium), also known as Chuan Xie Yong, may occur in the left or right hypochondrium. The bilateral hypochondrium of the human body is the pathway for the Qi of the Foot Jueyin Liver Meridian to enter and exit. Once obstructed and unable to be unblocked, stagnation leads to pain, causing blood to coagulate accordingly. Therefore, sores and toxins occurring above and below the hypochondrium all belong to the Liver Meridian. This condition often arises due to depression and anger leading to Liver Fire, or due to disharmony of Liver and Gallbladder Qi, with Wind and Fire battling internally, causing counterflow of Ying Qi, heat in the Blood, and aggregation. It is mostly seen in individuals with deficiency and frailty; those who are obese and have internal excess rarely suffer from this condition. In the early stage, Zhi Zi Qing Gan Tang (Gardenia Decoction to Clear the Liver) should be used to resolve stagnation and drain fire; when the abscess has formed but not yet ruptured, Si Miao Tang (Four Marvels Decoction) added with Qing Pi (Green Tangerine Peel) and Xiang Fu (Cyperus Rhizome) is indicated; when pus has matured, it should be lanced immediately, taking care not to damage the inner membrane; after rupture, Ba Zhen Tang (Eight Treasures Decoction) added with Shan Yu Rou (Cornus Fruit), Mu Dan Pi (Moutan Cortex), and Ze Xie (Alisma Rhizome) should be used to nourish Kidney Water. However, for those with Qi deficiency and weak Stomach function, one must not excessively administer Yang-tonifying herbs, lest the intake of hot-natured formulas exacerbate deficient heat, which could penetrate and damage the inner membrane; caution is essential. Furthermore, if the etiology is due to consumptive disease, such as a ruptured sore discharging foul-smelling putrid matter with thin, clear pus, and tonifying and supporting methods fail to respond, it is a fatal syndrome.

Lei Yong (Abscess of the Ribs), located between the ribs, is also known as Xia Ying Yong. It is also caused by the aggregation of Liver Fire, depression, and anger. Initially, there is a dull pain in the bone, gradually swelling up, later becoming large like a cup or bowl, with color either red or white, unbearable pain, and a sensation of internal intestines being twisted and pierced. If affected on the left, pain radiates to the right hypochondrium; if on the right, pain radiates to the left hypochondrium. Individuals with weak constitution find it difficult to endure. For abscesses and carbuncles in this area, death often results from internal attack by toxins. Upon contracting this affliction, urgent needle drainage of pus and blood is required to prevent internal invasion. If, by the second phase (approximately two weeks), thick pus drains upon rupture, it is auspicious; if clear water drains, it is ominous. Treatment methods refer to those for the preceding syndrome.

Fu Yong (Abdominal Abscess), also named Fu Pi Yong, occurs between the abdominal skin and fascia. It is toxin of the Spleen Meridian, resulting from consuming fried and greasy foods, excessive alcohol intake, or excessive sexual activity, leading to stagnation and aggregation of toxins. Regardless of side, there is long-standing dull pain, followed by the emergence of an abscess on the exterior of the skin; if the pulse at the Right Guan position is deep and rapid with severe abdominal pain, these are its signs. One must not overdose on purgative or attacking drugs; attempting to dissipate the swelling while excessively damaging Stomach Qi will result in the inability of the swelling to suppurate or heal, making recovery difficult. In the initial stage, Huo Ming Yin (Life-Saving Decoction) or Hua Du Chu Shi Tang (Toxin-Transforming and Dampness-Draining Decoction) is suitable; after rupture, Tuo Li Xiao Du Tang (Interior-Supporting and Toxin-Expelling Decoction) should be taken.

Qi Yong (Umbilical Abscess) occurs in the umbilicus, caused by accumulated heat in the Heart Meridian flowing into the Small Intestine Meridian, with toxin aggregation (The Heart and Small Intestine are interior-exteriorly related; heart heat transferred to the small intestine causes this toxicity). The swelling is large like a melon, protruding high like a bell, colored either red or white. However, the umbilicus is Shen Que (Conscious Pupil), an acupoint of the Ren Mai (Conception Vessel), where acupuncture is prohibited. Early dissipation is advisable; otherwise, internal ulceration is feared. If pus forms and breaks outward, it is auspicious. Initially, La Fan Wan (Beeswax and Alum Pill) should be taken frequently; for decoctions, Huang Lian Jie Du Tang (Coptis Decoction to Relieve Toxicity) combined with Wu Ling San (Five Ingredient Powder with Poria) is used, or Dao Chi San (Guide Out the Red Powder) added with Gui Wei (Tail of Angelica Root), Chi Shao (Red Peony Root), and Yin Hua (Chrysanthemum Flos) is also acceptable.

Lou Qi Chuang (Leaking Umbilicus Ulcer) may arise from Kidney deficiency with hyperactive fire, or from annoyance and Qi stagnation. Tonifying agents should be administered, and external application of Sheng Ji San (Flesh-Generating Powder) is recommended. Additionally, if infants urinate in the umbilicus due to deficiency of Liver and Kidney and failure of Qi to circulate and transform, it constitutes a pediatric consumptive failure syndrome, which is incurable.
