wormwood

蒿 is composed of the radical 艸 (grass) and 高 (high). 艸 is a pictograph of grass, while 高 depicts a multi-storied building. Thus, 蒿 portrays a scene of grass growing around a tall building and represents plants of the wormwood family. These plants have a strong fragrance and medicinal value, and in traditional culture, they are believed to have the ability to ward off evil and disease. If wormwood grows around a building, it signifies the owner’s virtuous character.
