Safety Overview
1.Chuan Xiong — At a Glance
Chuan Xiong, botanically known as Ligusticum wallichii, and sometimes referred to by its synonym Conioselinum anthriscoides, is a highly valued perennial herbaceous plant within the Apiaceae family, renowned for its aromatic and medicinal properties. This robust herb typically grows to a height of 50 to 100 cm, characterized by its hollow, sturdy stems that are smooth and vibrant green, often with reddish hues near the nodes or under intense sunlight. The foliage is distinctly tripinnate-compound, deeply lobed, measuring 15 to 40 cm in length and 10 to 30 cm in width, with sharply serrated margins and a glossy, dark green coloration, contributing to its lush appearance. Its complex, feathery leaf structure serves as a key identifying feature.
The plant flowers from late spring to early summer, producing abundant compound umbels densely packed with small, white to pale yellow flowers, each about 3 to 4 mm in diameter. These delicate clusters create a striking display, attracting various pollinators. Post-pollination, it develops small, ribbed schizocarpic fruits, but the primary medicinal part is its aromatic, irregularly shaped rhizome, which is harvested and dried for use. Ecologically, Chuan Xiong thrives in moist, well-drained soils rich in organic matter.
Its native range is confined to the mountainous regions of China, particularly in provinces like Sichuan, Yunnan, and Guizhou, where it is indigenous. It typically inhabits forest margins, grassy slopes, and valleys at altitudes ranging from 1,500 to 3,000 meters above sea level, indicating its adaptation to cooler, higher-elevation environments. The specific taxonomic classification sometimes includes Ligusticum chuanxiong S.H.Qiu, Y.Q.Zeng, K.Y.Pan, Y.C.Tang and J.M.Xu, encompassing horticultural varieties.
