Huang, female, 68 years old, first consultation on June 10, 1980. Twelve years ago, she suffered from "rheumatic heart disease" and the symptoms were controlled after treatment. However, since then, she has never sweated slightly throughout the year, experienced mental fatigue, feared wind, had a poor appetite, and found food tasteless. She sought medical treatment for over ten years without success. It was midsummer, the weather was hot, and without sweating, she felt uncomfortable all over and desired to sweat for relief.

Upon examination, the patient's complexion was dull, and her skin was without sweating upon touch. Her tongue was pale with a white and slippery coating, and her pulse was deep and slow. The pattern identification indicated cold-dampness internalized in the organs, leading to long-term damage to kidney yang, which could not warm the muscles and skin, and was unable to promote sweating to the surface, resulting in no sweating throughout the year. The treatment plan was to use Ephedra, Asarum, and Aconite Decoction to assist yang and expel pathogens through the exterior.
Prepared Ephedra 10g, processed Aconite 12g, Asarum 4g
After taking 3 doses, she began to sweat slightly and felt much more comfortable all over. After 7 doses, she sweated like a healthy person, and her limbs felt relaxed and free. A decade-long chronic illness was effectively treated within a week. She continued with the original prescription for 7 more doses to consolidate the effect.
