First, it is made of traditional Chinese medicine soaked in wine, which can preserve health. Tu Su wine is said to have been made by Hua Tuo, a famous doctor in the Three Kingdoms period. It is mainly prepared from rhubarb, atractylodes rhizome, aconite, cassia twig, ledebouriella root, aconite root and pepper. These drugs have a good health-preserving effect, and the spread of this custom is closely related to Sun Simiao, a famous doctor in Tang Dynasty.
Second, it had a certain preventive effect on infectious diseases and epidemics at that time. It is said that at that time, in the twelfth lunar month, Sun Simiao always sent a pack of medicine to all families, telling them to put the medicine in wine and drink it on New Year's Eve, which could be used to prevent and treat the plague. In fact, this medicine is the formula of Tu Su wine. It can be seen that Tu Su wine has a certain inhibitory effect on infectious diseases and epidemic diseases to some extent. This also makes Tu Su wine a custom handed down by people in the ancient Spring Festival.
Thirdly, according to modern research, Tu Su wine has the effects of warming yang, expelling wind and dispelling cold. According to modern research, Tu Su actually refers to an old house. Tu Su wine is called Tu Su wine because it is brewed in this house. At that time, it was widely drunk during the ancient Spring Festival, also known as Mingsui wine. Through the research of the Chinese Medicine Department of the Eighth Medical Center of PLA General Hospital, it was found that the wine made with this medicine formula really has the effects of warming yang, tonifying kidney, expelling wind and dispelling cold. This shows us the wisdom of the ancients to some extent.
