Every Dragon Boat Festival, especially women and children, should wear sachets. Tracing back to the origin of sachets, as early as the pre-Qin period, women wore ornaments made of five threads on their heads. It developed into a sachet in the Northern and Southern Dynasties, and in the Tang Dynasty, a fragrant pill filled with spices appeared. The main raw materials of sachet are realgar, mugwort leaf and smoked grass. Their functions were deified in ancient times. Nezha's red belly in "The List of Gods" can ward off evil spirits. People are familiar with the legend of the White Snake because they can't stand Xu Xian's persuasion and drink realgar wine to show their true colors. In fact, as early as "Bao Puzi boarded the club", it was recorded: "The Yellow Emperor wants to climb the Garden Mountain, and there are more snakes than them. Guang Chengzi taught him to wear realgar, and all his snakes went. " Later, this record was taken away by American W Ai Berhard. In his Dictionary of Cultural Symbols in China, he explained this record as follows: "There was a great plague in the Huangdi tribe. I heard that Guang is good at medical treatment, so I sent someone to ask how to cure the plague. Guangchengzi wrapped it in realgar and let them wear it. As a result, the disease was cured. "

During and after the Dragon Boat Festival, the climate is hot, mosquitoes and flies fly, poisonous gas rises, and epidemics germinate. The ancients believed that people who ate whole grains suffered from various diseases, and the diseases entered through the mouth, mostly due to evil and miscellaneous gas, which was inhaled through the nose and mouth. In the long-term struggle against various diseases, people found that drinking realgar wine and wearing sachets can exorcise evil spirits and detoxify, which has its medical principles. Say realgar and realgar wine first if you want to say sachet. Realgar is abundant in many places, and people make realgar into realgar wine in the process of continuous practice. "Ting Anne Lu" records: "Study realgar powder and broken Pugen, and drink it, which is called realgar wine." That is, realgar is added to the wine. Realgar, orange-red, can be used as medicine to solve the virus. Realgar wine is the wine of Dragon Boat Festival. In the past, Jianning almost brewed realgar wine at home, but most of them were drunk by men, and some women who could drink it also drank some. When children can't drink, adults soak their hands in wine, which makes the children's face, ears, nose, palms and feet foam. Later, people added Artemisia argyi leaves, smoked grass and other raw materials to realgar to make sachets for women and children to wear.

The sachet, with medicinal flavor, can be inhaled through the nose and mouth to achieve the effects of dredging meridians, eliminating pathogenic factors and strengthening the body, thus achieving the effect of eliminating diseases and strengthening the body. Realgar, wormwood and smoked grass all emit a strange fragrance, but snakes and insects smell it far away, which not only reduces the source of infection, but also plays a role in killing germs, eliminating sweat and odor and refreshing the mind.
