In the 1970s, I came across a simple remedy for sprains in a book of folk prescriptions. It was very straightforward and usually worked within three days. In the late 1980s, my father-in-law was winding up a wall clock. Since the clock was hung quite high, he used a small wooden stool to stand on. Unexpectedly, as soon as he stepped onto it, the stool collapsed, and he fell to the ground, spraining his back. He was in so much pain that he couldn’t move. When I found out, I took him to our factory’s hospital, but they didn’t have any effective solutions. So, I recalled the remedy from memory and prepared three doses of the herbal medicine (which cost only a few cents at the time). After taking the medicine, my father-in-law said the pain was mostly gone, though he still felt a bit uncomfortable. I prepared another dose, and after taking it, he fully recovered. At the time, I was puzzled: it was supposed to work in three doses, so why did it take an extra one? One day, I came across the original prescription and realized I had misremembered the dosages. One ingredient was supposed to be three qian, and the other one and a half qian, but I had mixed them up. The prescription is as follows: **3 qian of turmeric root (Curcuma)** and **1.5 qian of costus root (Saussurea)**. (To be honest, since I can’t find the original prescription anymore, I can’t guarantee if these dosages are accurate. But even if they’re not, the remedy still worked well—it just required an extra dose.) **Contributor:** Teacher Cai Fengcheng --- This translation maintains the original meaning while using natural and idiomatic English expressions.
