Distribution and habitat
Vincetoxicum auriculatum is native to Asian temperate and tropical regions; found in China (in Sichuan, Xizang, and Yunnan provinces), Bhutan, Nepal, and the northern parts of Pakistan and India (it is also native to Kashmir). Its habitat is mountainous shrubland terrain, at elevations from 2800 to 3600 meters.
Studies
Ethanol extracts derived from roots of V. auriculatum are being studied for use in anti-cancer medicine; one preliminary study found extracts to have some cytotoxic effects on certain human tumor cell lines. The tests were conducted, both in vitro and in vivo, on both human subjects, and mice.
Penupogenin [27526-87-0] & Qingyangshengenin [84745-94-8] are steroidal aglycones isolated from the roots of Cynanchum auriculatum.

Why this record matters
“Vincetoxicum auriculatum” is worth following because a concise public description often conceals a longer documentary argument. Here, Vincetoxicum, auriculatum and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Feb 5, 2026. The linked authority identifier is Q56984796. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
