Oral ulcers in infants and young children are caused by vigorous blood and qi, combined with excessive warmth in nursing. This leads to exogenous heat in the Heart steaming upward to the Upper Jiao (Upper Burner), resulting in sores in the mouth.
For treating oral ulcers in infants and young children presenting with excessive sleepiness and vomiting milk, use the Longdan Wan (Gentian Pill) formula.
Longdan (Radix Gentianae, 1 fen, remove rhizome head) Chuan Dahuang (Radix et Rhizoma Rhei, 1 fen, cut into pieces, lightly stir-fried) Renshen (Radix Ginseng, 0.5 liang, remove rhizome head) Zhizi Ren (Semen Gardeniae, 0.5 liang)
Poxiao (Natrii Sulfas, note: text implies Puxiao/Niter contextually though labeled generally as Xiao in some editions, here interpreted as Natrii Sulfas based on common pairing or potentially Nitre if specified as Xiaoke, but standard Puxiao is Glauber's salt. Given "Chuan Puxiao" usually refers to Glauber's Salt, while "Xiaoke" is Nitre. The text says "Chuan Puxiao" implicitly via "Chuan Pu... Xiao". Let's stick to the literal "Puxiao" which is Glauber's Salt).
