The child was a male, 1 year and 5 months old. His father complained that he had been suffering from a head sore for several months, and currently there is a lump protruding from the left side of his head at the back of his head in the occipital bone area, which is red in color and hard when pressed, and there are several small lumps in the surrounding area, and there is a red scar in the frontal bone area of his head near the front median line after the sore, and there is no hair growth at the scar, and the fingerprints are red and purple and faint, with normal development and no discomfort. The parents told me that it is difficult to feed herbal medicine to children, and asked for an easy way. The “Treatise on the Origin of the Diseases”: The head sores of children are caused by heat from the internal organs, and the heat rushes up to the head, while the wind and dampness multiply it, and the dampness and heat fight each other to break the blood and become sores. The Infant’s Treasure Book: Head sores in children are caused by heat in the six yang, and the pulse of the six yang eats in the head, so heat multiplies in the yang and does not flow. When I saw the raised head sores in front of me, I suddenly remembered the summer cress that disperses knots and reduces swelling. This disease is born in summer, maybe it will disappear because of Xia Ku Cao, let’s give it a try. Prescription: Xia Gu Cao Cao 15g, 7 doses. Medical advice: each dose of medicine plus an egg fried for 15 minutes, then remove the shell of the egg, and then put the peeled egg back into the frying for another 5 minutes, eat the egg. Half a month later, his father said that the child’s head sore had been cured. The effect was beyond my expectation. 7 servings of medicine cost $8.40, and the simplicity and cheapness of Chinese medicine was evident. Later, I looked up the “Shen Nong Ben Cao Jing” Xia Ku Cao article: “taste bitter, pungent, main cold and heat scrofula, rats, head sores, broken disease, dispersing galls, knotted gas, foot swelling, damp paralysis. Lightens the body. It has a name of Xuju and a name of Naidong. Born in Chuangu. The famous doctor said: a swallow face, born in Shu County, picked in April.” The original “Ben Jing” recorded that Xia Ku Cao originally can treat head sores, but their own reading is not detailed enough, do not know this effect.
