Most of the drugs used by the ancients in China to sober up were some Chinese herbal medicines such as Pueraria lobata and Pueraria lobata. Looking up the medical classics of China in the past dynasties, there are about 150 kinds of prescriptions for sobering up and abstinence, but the prescriptions for sobering up account for more than 90%.
Durbin in the Song Dynasty recorded: "Yuzong has a shark, and the cloud can sober up without its artificial method." In modern terms, this sentence means that there is something called mackerel in Yuzong. Others say it can be used to sober up, but the method of making it is not recorded.
In fact, in addition to these records of Durbin, there are many secret recipes about hangover in ancient China. Moreover, for different wines, there were different sober-up methods in ancient China. It's just that these sober-up methods are too complicated, and almost all of them are recorded in the form of prescriptions, so it's not convenient to elaborate here. Moreover, in ancient China, "sugar" was definitely added to the prescription of sober-up, which can be said to be similar to the modern method of sober-up, indicating that the ancients in China were quite clever and could think of using sugar to sober up.
Apart from China's prescription for sobering up in ancient times, there are actually ways to sober up in ancient times all over the world. It's just that the way they sober up is too wonderful. Some use sheep milk to sober up, some use tree juice, and some even lick their own sweat.
