It is stated in the treatise: The classics record that dysfunction of the six fu-organs leads to stagnation and condensation, resulting in carbuncles. This is because the Ying (Nutritive) and Wei (Defensive) qi of infants are obstructed and stagnant, failing to flow smoothly, reversing within the muscle tissues, causing swelling and nodularity of the muscles. The skin is thin and lustrous, which is the manifestation of a carbuncle. Since the carbuncle cannot be resolved internally, it suppurates, ruptures through the skin, and becomes an ulcer; thus, it is termed "carbuncle-ulcer" (Yong Chuang).

**Rhino Horn Decoction (Xijiao Tang)** for treating infantile carbuncle ulcers:

* Aurantii Fructus (Zhiqiao), pith removed and stir-fried with bran
* Scutellariae Radix (Huangqin), sliced *(Note: Text says 'Huang', context implies Huangqin or Huanglian, usually Huangqin in this formula context, but strictly translating character 'Huang' as generic yellow herb if ambiguous, however standard formula uses Huangqin. I will use Scutellariae Radix based on standard formula composition for this condition, or stick to literal 'Yellow Herb' if strict. Given 'Huang' alone often refers to Huangqin or Huanglian, and previous line had Huangqin, here likely Huangqin or Huanglian. Let's assume Huangqin/Scutellariae Radix or Huanglian/Coptidis Rhizoma. In Song texts, 'Huang' often abbreviates Huangqin. I will use Scutellariae Radix)*.
