Discussion on umbilical sores in children: When the umbilical cord is cut, external injury by wind-pathogens (Wind-Evil) may cause the umbilical sore to fail to heal. Use Fanlong San (Alum and Dragon Bone Powder): Calcined Alum (Guifu, 5 fen) and Fossil Bones (Longgu, 5 fen), ground together into a fine powder. Apply a small amount directly to the umbilicus.
In a case where a child’s umbilicus exuded fluid and was painful, dry application of Calcined Alum powder was used.
Another prescription: Apply powder of Phellodendri Cortex (Huangbai).
Yet another method: Burn silkworm cocoons to ash while preserving their medicinal properties, and apply the ash to the affected area.

A treatment for abdominal pain due to intestinal parasites in children: Take one Crotonis Fructus (Badou), remove the shell, crush it, and remove the oil. Grind it evenly with one grain of Cinnabar (Zhusha). Crack open an egg at the top, remove a little of the albumen (egg white), insert the medicine, mix well, and seal the opening with paper. Place the egg in a bamboo ring inside a pot, boil it thoroughly in water, and let the child eat it. Alternatively, administer with tea infusion. This will expel the accumulated parasites and is highly effective.
