Traditional use
Traditionally used for earache, with the flowers folklorically associated with eye conditions. Some preclinical laboratory studies have reported analgesic activity from leaf extracts and anthelmintic activity from rhizome extracts against the earthworm model Pheretima posthuma — findings from animal/lab models, not yet clinical evidence in humans.
Evidence status: Experimentally demonstrated
A controlled mouse study found leaf extracts produced measurable analgesic effects (hot-plate and writhing tests), and rhizome extracts caused paralysis in the earthworm Pheretima posthuma, an established anthelmintic-activity model.
Evidence base: animal (mouse) and in vitro (earthworm) models
