Packera aurea
Eastern North American groundsel used by many Native American nations as a uterine tonic and women's herb, with pyrrolizidine alkaloid cautions.
Life Root (Packera aurea) is an Eastern North American groundsel traditionally used by Cherokee and Menominee peoples as a uterine tonic and women's herb. Its primary modern applications include uterine stimulation, emmenagogue effects, diuresis, and astringency, but its use is limited by the presence of hepatotoxic pyrrolizidine alkaloids (senecionine, integerrimine, florosenine). Evidence level C supports its traditional uses, though safety concerns restrict its application to short-term, low-dose tincture regimens.
The pyrrolizidine alkaloids (PAs) in Life Root, particularly senecionine and integerrimine, are metabolized in the liver to toxic pyrrole derivatives that cause hepatotoxicity and veno-occlusive disease. The uterine stimulant and emmenagogue effects are thought to arise from cholinergic receptor activation or direct smooth muscle contraction, though this is not well-studied. Flavonoids and tannins contribute diuretic and astringent actions via inhibition of prostaglandin synthesis and protein precipitation, respectively.
