Introduction of realgar wine:
The custom of drinking realgar wine on Dragon Boat Festival was very popular in the ancient Yangtze River basin. As the saying goes, "drinking realgar wine will cure all diseases." Realgar is a mineral, commonly known as "Jiguanshi". Its main component is arsenic sulfide, which contains mercury and is toxic.
The common realgar wine is made by adding a small amount of realgar to white wine or homemade yellow wine, and there is no pure drink. Realgar wine has the efficacy of sterilization, insect repellent and detoxification, and traditional Chinese medicine is also used to treat skin diseases. In ancient times, when there was no disinfectant such as iodine, soaking in realgar could detoxify and relieve itching. For children under drinking age, adults apply realgar wine to forehead, ears, ears, hands, feet, heart and other parts to disinfect and prevent diseases. The ancient poem goes: "Only when I was a child, I didn't forget to hold Evp as the king." It means that on the Dragon Boat Festival, children take mugwort leaves, put on calamus and write the word "king" on their foreheads with realgar wine to ward off evil spirits and prevent epidemic. Sprinkle realgar wine on corners, bed bottoms and other places to repel insects and clean the environment. However, modern scientific research shows that external use of realgar wine is ok, but it is harmful to drink, so it must be used with caution.
Realgar, as a traditional Chinese medicine, can be used as an antidote and insecticide. Therefore, the ancients believed that realgar could inhibit snakes, scorpions and other pests. "Good can kill all poisons, eliminate all evils, cure all poisons, and be admired by people. Tigers and wolves lurk in the mountains and enter the Sichuan water to avoid all poisons."
