Traditional Uses
In Argentine and Brazilian folk medicine, Pterocaulon angustifolium is used as an antiseptic and antifungal agent, particularly for skin complaints and infections; documented traditional use in Argentina dates to the 1980s, and the genus is broadly employed in Brazilian traditional medicine against bacterial and fungal skin diseases (Mors et al., 2000; Stein et al., 2018). Coumarins are considered the active antimicrobial constituents.
Botanical Description
Pterocaulon angustifolium is an erect, aromatic perennial herb of the sunflower family (Asteraceae), native to southern Brazil, Paraguay, Uruguay and northern Argentina. It is distinguished by conspicuous winged stems formed where the bases of the narrow, decurrent leaves run down the stem, giving the plant a characteristic ridged appearance. The leaves are linear to narrowly lanceolate, dark green and often woolly-white beneath. Small flower heads are densely aggregated into terminal spike-like or cylindrical clusters, producing whitish to cream florets followed by small dry achenes bearing a pappus. The species favours open grasslands, sandy soils and disturbed ground in subtropical South America. Like other members of its genus it is notably rich in coumarins, which give the dried plant a characteristic scent and are regarded as its principal bioactive constituents.
