Zhang, male, 9 years old, diagnosed on October 13, 1978. The child has been suffering from excessive thirst for half a year, drinking 4 thermos bottles of water every day and night, yet still feeling dry mouth and tongue, poor appetite, mental fatigue, and clear, frequent urination. Initially examined at a hospital, cranial imaging showed no abnormalities, urine sugar was negative, only the urine specific gravity was slightly lower than normal, and no clinical diagnosis was confirmed. After discharge, more than ten doses of Chinese medicinals were taken, with most doctors diagnosing it as stomach yin deficiency and prescribing medications such as Coastal Glehnia Root, Ophiopogon Tuber, and smallpox powder, but the effect was unclear.
Observation of the tongue texture showed a pale red color with a white slippery coating, and the pulse manifestation was deep and slippery; reviewing the symptoms, there was no significant heat manifestation. The pattern identification indicated internal retention of water-dampness and disturbance of qi transformation, leading to the inability of water and fluids to ascend, and thus should be treated with Five Ingredients with Poria Powder to transform qi and drain water, and distribute body fluids. Prescription:
Cinnamon Twig 6g, Poria 9g, Alisma 9g, White Atractylodes Rhizome 10g, Polyporus 10g
After taking 5 doses of the medication, the child's excessive thirst and drinking significantly reduced, with water intake decreasing to 2 thermos bottles per day and night. The previous prescription was effective, so it was continued for another 5 doses. Several months later, it was reported that the child had recovered.
