What Gua Lou Niu Bang Tang is for
Gua Lou Niu Bang Tang is for a breast that has turned hot, red and swollen, with skin that is tight, tender and sometimes cracked. The congestion sits in the tissue rather than across the whole body, and it is treated at the stage before an abscess forms. The formula clears the Heat in the skin and frees the Qi that is holding the swelling, which is why it is used while the tissue is still inflamed rather than discharging.
The skin picture is a single region. The breast is red, hot and swollen, the overlying skin is tense and shiny, and it may be cracked at the nipple or across the surface. Pressure is painful and the tissue feels hard rather than soft. The redness is the Heat, and the hardness is Qi and Blood held in the region. Cracks on that base are not the dry cracks of a depleted surface: they sit on hot congested tissue and heal only as the congestion resolves.
Gua Lou Ren and Tian Hua Fen disperse the swelling and soften the hard area, which is what a congested breast needs before the tissue can settle. Niu Bang Zi vents the Heat outward through the skin, while Jin Yin Hua, Lian Qiao, Huang Qin and Zhi Zi clear it and resolve the toxicity. Zao Jiao Ci helps the congestion either resolve or discharge. Chai Hu and Qing Pi free the Liver Qi that the tradition holds responsible for the tightness, because the breast region is where that Qi arrives.
The direction is early clearing with regional dispersion rather than strong purging. It is used while the breast is hot and hard and has not formed pus, because once an abscess forms the approach changes and the tissue needs to drain. A red hot painful breast with fever needs medical assessment for mastitis, and this formula sits alongside that care rather than replacing it. It is not for a depleted mother with scanty milk and pale, cool skin, which is the opposite picture and needs tonifying instead.

Patterns it treats
Toxic-Heat
A single hot, red, swollen and painful breast, with tense shiny skin that may be cracked over the congestion. Heat produces the redness and stagnant Qi produces the hardness. The formula clears the toxicity and frees the Qi together, which is why it is used before an abscess forms.
How the formula is built
The formula clears and disperses in balance. The cooling herbs deal with the Heat and toxicity, while Gua Lou Ren, Zao Jiao Ci and the Qi-moving group disperse the swelling and free the stagnation. That is why it is used in the early congested stage.
Skin conditions it is used for

Origin and history
Wai Ke Zheng Zong (外科正宗, Orthodox Manual of External Medicine) by Chen Shigong, Ming dynasty, 1617.
Chen Shigong's surgical manual of 1617 contains this formula for the hot congested breast, a common problem in lactation. Its combination of clearing with regional dispersion made it the standard early-stage treatment before suppuration.
Classical record
Chen Shigong recorded the formula for acute hot congestion of the breast, clearing the Heat and dispersing the swelling before an abscess could form.

Evidence note
No controlled trial of this treatment in skin conditions was identified for this entry. What is described here rests on the classical and later materia medica record and on traditional clinical use, not on controlled trial evidence, and it is not a prediction of benefit. Where skin-specific research does exist it is linked above.
