1, evil spirits
There is a reason to hang wormwood and cattail (Pujian) at the entrance of Dragon Boat Festival. Usually mugwort leaves, banyan trees and calamus are tied into a bundle with red paper and then inserted or hung on the door. Because cattail (Acorus calamus) is the first of five auspicious days, symbolizing evil sword, because the growing season and shape are regarded as "the breath of a hundred yin", and the leaves are sword-shaped and can be inserted at the door to ward off evil spirits.
Step 2 pray for blessings
Wormwood represents a hundred blessings, and inserting it at the door represents a hundred blessings, which can make the owner healthy. On the Dragon Boat Festival, wormwood is hung on the door, which indicates that the family is healthy and lucky to carry around all year round.
3. Insect repellent
Artemisia argyi is also known as Artemisia argyi and Artemisia argyi. Its stems and leaves contain volatile aromatic oils. Its unique fragrance can repel mosquitoes, flies, insects and ants and purify the air.
Myths and legends of wormwood
Legend has it that plague and various pests and diseases broke out among the people in ancient times every April and May, and the people complained bitterly. So the Jade Emperor sent Taibai Venus to visit the people and control the plague. When Venus came down to earth too white, she found herself from all corners of the country, but her mind was different. Some people are good people, while others are bad people. In order to punish the evil, promote the good and implicate the innocent, she said to the good-hearted people: "Every year on the fifth day of May, I put on a sachet and put mugwort leaves on the door, and all plagues will be removed, and the auspicious light will be brilliant."
Strangely, from then on, all adults and children with sachets ran away when they saw pests, but the wicked without sachets were poisoned by pests. Since then, there has been the custom of carrying sachets with you and hanging wormwood in front of the door during the Dragon Boat Festival. As a pharmacist in Li Shizhen, wormwood contains aromatic oil, so it can be used as an insecticide to kill pests and diseases. During the Dragon Boat Festival, the summer solstice approaches, the weather turns hot, the air is humid, mosquitoes breed and epidemics increase.
Ancient people lacked scientific concepts and mistakenly thought that all diseases were caused by ghosts and evil spirits. Therefore, Artemisia argyi and Acorus calamus were tied into human shapes and hung in front of the door in the early days of the festival to drive away ghosts and evil and keep healthy. In fact, it is the fragrance of these two kinds of grass that really purifies the environment and repels the plague.
