The *Gui Yi Fang* states: When a red carbuncle (Chi Se Ju) appears on the forehead and anterior brain, as well as in the palms of the hands, if it does not ulcerate within ten days, death ensues. It can be pricked to bleed on the seventh day; if there is no pus formation by the seventh day, it is incurable.

The *Gui Yi Fang* further states: If a carbuncle, boil (Jie), or abscess (Yong) develops at either the left or right Taiyang acupoint, and fails to ulcerate within five to seven days, toxic qi flows into the eye socket and attacks the eye, causing it to remain closed. After applying medication to rupture the lesion, one must be cautious to prevent external wind-dampness from invading; once invaded, it damages the eyeball and the eyelids, resulting in severe disease. This is named Yong Ju (Brave Carbuncle), also known as Nao Fa Ju (Brain Hair Carbuncle). It belongs to the Foot-Yangming Stomach Channel. If clear, thin black blood flows out or the ulceration penetrates to the brain, death ensues.

Gu Shicheng states: The treatment method for Taiyang Ju (Carbuncle of the Taiyang region) is identical to that for general Yong Ju (abscesses and carbuncles); no separate principal formula is established.

Chen Shigong states: Bin Ju (Carbuncle of the sideburns) arises from the reckless movement of Ministerial Fire (Xiang Huo) in the Hand-Shaoyang Sanjiao (Triple Burner), compounded by Kidney Water's failure to generate Wood (Liver). Alternatively, it may result from external contraction of Wind-Cold. However, this channel has abundant Qi but scarce Blood, and the muscles are thin, making putrefaction and suppuration most difficult. These conditions are caused by an irritable and violent temperament, excessive sexual activity leading to Blood deficiency and Fire agitation, and Liver Qi stagnation forming a carbuncle. Initially, alternating chills and fever occur, with dizziness and pain penetrating to the Taiyang region. In severe cases, the ears, eyes, and sideburns become diffusely swollen. Treatment should not involve reckless use of acupuncture or moxibustion. If upon initial appearance of the sore, chills predominate over fever, dry mouth with thirst favoring hot drinks, and the six pulses are deficient, rapid, and weak, accompanied by a hard nodule that is mostly painless, without ulceration or pus, and with a scattered root, this indicates Deficiency of True Qi and Excess of Pathogenic Qi. The primary treatment is to support the interior (Tuo Li) to promote suppuration, assisted by detoxification. If upon initial appearance, heat predominates over chills, dizziness and headache occur, dry mouth and tongue with thirst favoring cold drinks, constipation and dysuria, and the six pulses are deep, solid, and forceful, accompanied by swollen and painful sores, fever, easy putrefaction and suppuration, but with a fixed root and localized swelling, this indicates Excess of Righteous Qi and Deficiency of Pathogenic Qi. The primary treatment is detoxification, assisted by supporting the interior. Generally, when Righteous Qi prevails, Pathogenic Qi becomes deficient; when Righteous Qi is deficient, Pathogenic Qi becomes excess. When Righteous Qi prevails, the presentation is Excess; when Pathogenic Qi prevails, the presentation is Deficiency. There is necessarily a trade-off where one prevails and the other declines; Evil and Righteous Qi cannot coexist. To make the pathogen deficient, it will naturally become deficient without requiring damage to the body. (From *Waike Zhengzong*)

It is also stated: In some cases, thirst symptoms appear for one and a half to two years before any sore is visible, worsening over time, before developing into Bin Ju. The color and shape are often purple-black, the sores are flat and depressed, hard without pus, toxic flow spreads to the ears and neck, accompanied by foul odor, lackluster complexion, listlessness, and poor appetite. All these constitute untreatable conditions.

Hu Gongbi states: The sideburn area is traversed by the Foot-Yangming Channel. Carbuncles arising from accumulated Heat in the Lung and Stomach ascending and obstructing are common. Manifestations include alternating chills and fever, vomiting and nausea, spontaneous headache, and dry nose. If the carbuncle is deeper than one cun, it is untreatable.

Chen Yuangong states: Sudden onset of a carbuncle in the sideburns with redness, swelling, and protrusion, causing edema of the head, face, eyes, and nose, differing from the norm, indicates Yang Toxicity. Since both sideburns are near the Taiyang region, which is a Yang position where Yin Qi cannot reach, it is treated as a Yang syndrome. However, it often transforms into a Yin syndrome; therefore, Yin-nourishing herbs should be added to Yang-warming formulas to prevent such transformation. If already ulcerated, Yin herbs should significantly outnumber Yang herbs. A proposed formula is Li Bin Tang. (From *Waike Jian*)

Shen Douyuan states: Bin Ju occurs in the Foot-Yangming Stomach Channel, which is rich in Qi and Blood, specifically at the Touwei acupoint. It begins like a boil, gradually becoming large and hard as stone, with skin resembling pigskin with brown pores. Delirium and confusion during sleep, vomiting of fresh blood, and spread to the limbs indicate a case with only one chance in ten thousand of survival. (From *Waike Qixuan*)

Gu Shicheng states: Bin Ju should be treated by nourishing Liver Blood and supporting the interior to form pus. Cold-cooling herbs should not be used lightly. After ulceration, avoid wind. Initially, if millet-grain-sized papules cause itching without pain, do not scratch them; cover immediately with plaster. If external wind invades, causing diffuse swelling and congestion of the head and eyes, the root will become hard. Caution is essential.
