Woody is a general term used for two closely related plants: *Yunmuxiang* (*Saussurea costus*) and *Chuanmuxiang* (*Dolomiaea souliei*). *Yunmuxiang*, also known as *Guangmuxiang* or *Aozhuxiang*, belongs to the *Compositae* family, while *Chuanmuxiang* is part of the *Chrysanthemum* genus and is native only to China. Both are wild plants, not cultivated, and are commonly found in alpine grasslands and shrubs in regions such as Sichuan, Yunnan, and Tibet.
The rhizomes of both species are highly valued in traditional Chinese medicine for their therapeutic properties. They are often used to treat digestive issues, reduce inflammation, and promote overall well-being. These plants have been used for centuries by local communities and are still an essential part of herbal practices today.
Woody plants, which include these species, are typically climbing vines that can grow up to 6–10 meters tall. They are evergreen or semi-evergreen, with green branchlets that may have few or no thorns. The leaves are pinnately compound, measuring about 2–3.5 cm in length and 0.8–1.8 cm in width. The flowers form corymb-like inflorescences at the tips of short branches, with each flower ranging from 2–3 cm in diameter. They come in white or yellow colors, and some varieties have single or double petals. Their strong, pleasant fragrance makes them popular in ornamental gardens.
Flowering occurs between April and July, and the fruits—nearly spherical—appear from September to October, reaching a diameter of 3–5 cm. These plants are not only botanically interesting but also culturally significant, representing the rich biodiversity of China’s mountainous regions. Whether used for medicinal purposes or as decorative flora, woody plants like *Yunmuxiang* and *Chuanmuxiang* continue to play an important role in both nature and human life.
