What are the names of the plants in the Dragon Boat Festival?

Planting Artemisia argyi and Acorus calamus on Dragon Boat Festival. The fifth month of the lunar calendar was called "evil month" in ancient times. From the climate point of view, people are easily infected when they gradually enter the hot summer and are filled with damp heat, which is the time when disasters and epidemics prevail. Therefore, before and after the Dragon Boat Festival, it is fashionable to insert calamus and mugwort leaves on doors, which are called "Pujian" and "Ai Hu" to ward off evil spirits and avoid disasters. Acorus calamus, also known as "water sword", is also called "elegant flowers and plants" with orchids, chrysanthemums and daffodils. In our traditional culture, this is the spirit of epidemic prevention and exorcism. Acorus calamus claims to be able to kill thousands of disasters. During the Dragon Boat Festival, calamus and Folium Artemisiae Argyi are hung on doors and windows, and calamus wine is drunk to ward off evil spirits and prevent epidemic. Burning calamus in summer and autumn can repel mosquitoes and insects. Acorus calamus, which is listed as the "top grade" medicinal material, is pungent and flat in nature, and has the effects of resolving phlegm, inducing resuscitation, eliminating dampness and harmonizing the middle energizer. Folium Artemisiae Argyi, a perennial herb of Artemisia in Compositae, is distributed in most parts of China, with shriveled leaves, soft texture and fragrant smell. Its stems and leaves contain volatile aromatic oils. Its unique fragrance can repel mosquitoes, flies, insects and ants and purify the air. Mostly on the roadside and on the grass. Wormwood represents a hundred blessings. China has had the custom of "inserting willows in Qingming Festival and wormwood in Dragon Boat Festival" since ancient times. On the Dragon Boat Festival, people regard wormwood as an important part of the festival and put it on the lintel or hang it in nave.
