According to research, the origin of Guiling Ointment is Wuzhou, which was called Cangwu County in ancient times. During the Three Kingdoms period, Liu Beixin, the emperor of Shu, fell out of power, and the indigenous people in the southern counties took the opportunity to rise up and decide to change the dynasty. Zhuge Liang personally went out to quell the chaos. This is probably the life story of "seven capture Meng Huo" in the Romance of the Three Kingdoms. Legend has it that Zhuge Liang was stationed in Cangwu County when he went south. Most of the soldiers at that time were northerners. When I first arrived in the south, I was acclimatized, and most of the soldiers vomited and diarrhea, which seriously affected their combat effectiveness. Zhuge Liang was very anxious and hurried to ask the locals. The local people said that the climate in Wuzhou was hot and humid and foggy (called miasma in ancient times), so they presented a wonderful recipe and drank it with local specialty turtles and clay pots. Zhuge Liang asked the sergeant to try it, and the effect was fantastic. Most of the soldiers recovered. This allusion is not recorded in the official history, so it should be fabricated. But it is true that the climate in Wuzhou is hot, humid and foggy. It is also true that Guiling Ointment is a traditional folk medicinal diet in Wuzhou, and Wuzhou is the origin of Guiling Ointment. As early as the 1940s, there was production and operation of Guiling Ointment in Wuzhou.
