Nine years ago, I was told a story by one of my herbology professors. She grew up during the Cultural Revolution in China in a poor and rural section of the country. When she was a little girl, she experienced a toothache in one of her molars. Her grandmother mixed Shi Gao (gypsum) with a raw duck egg and gave the mixture to her for the toothache. The toothache being gone, the little girl realized that if she feigned another toothache, she would get another duck egg (eggs were very hard to come by in that area and were quite a treat!).
