Saposhnikovia divaricata, known as
fángfēng 防風 (lit. "protect against the wind") in Chinese,
bangpung in Korean, and
siler in English, is the sole species in the genus
Saposhnikovia (family Apiaceae). The plant is still frequently referenced under the obsolete genus name Ledebouriella in many online sources devoted to traditional Chinese medicine.
