Mr. Kang, male, 45 years old. Visited on October 25, 1980. He has a history of hypertension for more than 10 years, with a feeling of distension in his right arm and numbness in his right thumb and index finger for several days. In the past two nights, he also experienced distension in his lower limbs, accompanied by frequent calf cramps and unbearable pain, making it difficult to move. The night before last, the episodes occurred three times, and last night, they occurred six times, causing him to stay awake all night. His pulse is wiry and thin, and his tongue texture is slightly red with a yellow, greasy coating. The tongue body is swollen with tooth marks. The "Treatise on Cold Damage Diseases" states, "For foot cramps... administer Peony Root and Liquorice Root Decoction, and the foot will stretch." Therefore, the prescription was:
Peony Root 31g, raw Liquorice Root 31g
. After taking one dose of the medication, the foot cramps did not occur that night, and the distension in the upper and lower limbs also decreased. However, the numbness in the fingers remained unchanged. After several days of observation, there was no recurrence.
