Introduction to the Source Plant, Distribution, and Growth Environment
Cynanchum atratum is a perennial climbing plant, typically found in hilly or mountainous regions. It is distributed across several provinces in China, including Hebei, Shanxi, and Shandong. The plant thrives in sunny or partially shaded environments, preferring well-drained soils. Its vine-like stems can reach several meters in length. [^3]
