On the Dragon Boat Festival, it is customary for everyone to drink a cup of wine early in the morning, as it is believed to ward off evil spirits. Drinking and spraying realgar wine is a traditional folk custom of the Dragon Boat Festival. There is a saying: "On the fifth day of May, drink realgar wine to celebrate the Dragon Boat Festival."
This is because people in ancient times believed that the Dragon Boat Festival, which falls on the fifth day of the fifth lunar month, is an "evil month and evil day", and the day with the most poisonous gas.
Therefore, on this day, people would cut the harvested Pucao Root into small pieces, dry them in the sun, mix them with a little realgar, and soak them in white wine, believing that this would have the effect of expelling snakes and warding off evil spirits.
Pucao Root grows in ditches, ponds, lakesides, and grasslands along rivers. Except for Xinjiang and Tibet, it is widely distributed throughout the country.
