Eremophilane sesquiterpenes have been isolated from P.aurea: trans-9-Oxofuranoeremophilane, 8α-ethoxy-10αH-eremophilenolide, 3α-angeloyloxy-9-oxo-10αH-furanoeremophilane.

„The North American liferoot (S.aureus) has also been widely used to treat gynaecological problems - mainly to induce menstruation and to reduce excessive bleeding (as douche).“
As the plant contain liver-toxic pyrrolizidine alkaloids (with haemostyptic properties in animal studies), senecio species are no longer considered safe for internal use.
