Wang Fuchun, newly married for a month, contracted a cold-damage disease of the Taiyang, with symptoms of headache, fever, and fear of cold. Mistakenly using a tonic formula, the pathogenic factors had no outlet, causing pain throughout the joints, profuse sweating and heat steaming from the head, a complexion as yellow as an orange, and urine the color of Gardenia juice. The treatments he received were all moistening and tonifying, which only intensified the urgency. When all other doctors' skills were exhausted, they finally called me for a diagnosis.

Fortunately, his pulse showed no signs of yin, his abdomen was not full or knotted, and his chest showed no signs of vomiting or hiccups. I said, although this condition is critical, I can cure it with one dose. His family was skeptical but trusting, and indeed, after taking the medicine, he recovered. This case is similar to the one in Zhang Zhongjing's "Treatise on Cold Damage Diseases" where a Taiyang disease, due to lack of sweating, causes pain all over the body, head sweating, fever, and yellowing of the skin, for which the Ephedra, Forsythia, and Rice Bean Decoction is prescribed. The idea is to induce sweating and promote urination, allowing the pent-up pathogenic factors to be resolved both externally and internally.
