According to *Chao Shi Bing Yuan* (Source of Diseases by Chao), regarding the condition of bleeding from the roots of teeth in children: The meridians of Hand-Yangming and Foot-Taiyang both enter the teeth. When wind-pathogens invade the meridians of children and contend with blood, causing deficiency and heat in the blood and qi, bleeding occurs at the roots of the teeth.

Simultaneously, boil the bamboo shavings thickly to extract the juice. Do not add salt. Rinse the mouth with the juice when the temperature is suitable, continuing throughout the day as needed.
