Pergularia L. is a genus of flowering plants in the family Apocynaceae (order Gentianales). In its current circumscription the genus is monotypic, comprising a single accepted species: Pergularia daemia (Forssk.) Chiov., a perennial twining herb native to tropical and subtropical South Asia, Africa, and Australia, where it commonly grows along roadsides and disturbed ground.
The genus has undergone substantial taxonomic revision over its history: numerous species once placed under Pergularia have since been transferred to related genera within Apocynaceae, including Marsdenia, Telosma, Strophanthus, Cionura, Vincetoxicum (syn. Tylophora), and Vallaris.
Pergularia daemia has been studied extensively for its ethnomedicinal and pharmacological properties, with documented antiinflammatory, hepatoprotective, anticancer, antidiabetic, antioxidant, antibacterial, antifungal, analgesic, and anti-infertility activities reported in the scientific literature.
Distribution
Pergularia daemia, the sole accepted species, is native to tropical and subtropical regions spanning South Asia (including India), Africa, and Australia, where it frequently occurs along roadsides and in disturbed habitats.
Taxonomy Notes
Pergularia has been substantially reduced through taxonomic revision: species formerly placed here have been reassigned to Cionura, Marsdenia, Strophanthus, Telosma, Vincetoxicum (syn. Tylophora), and Vallaris, all within Apocynaceae. The genus is now considered monotypic, with only Pergularia daemia accepted.
Cultural Uses
Pergularia daemia has a long history of use in traditional medicine across South Asia. Documented pharmacological activities include antiinflammatory, hepatoprotective, anticancer, antidiabetic, antioxidant, antibacterial, antifungal, analgesic, anti-infertility, and central nervous system depressant effects.
