Traditional Uses
In Mexico, where the species is endemic and has been recorded in herbal and botanical manuscripts since the sixteenth century, the flowers and roots are prepared to treat abnormal vaginal discharge and bleeding, cough, and chest pain, and the plant is taken for 'nervios' (anxiety and depression) and as an anti-inflammatory remedy (Bye and Linares, 2022). Pharmacological work has lent support to several of these uses: an ethanol extract of the roots showed antidepressant-like activity in mice, with the flavonoid glycoside linarin identified as an active principle, while a methylene chloride extract of the aerial parts demonstrated anti-inflammatory activity (Bye and Linares, 2022; Perez-Garcia et al., 2008).
Botanical Description
Cirsium ehrenbergii is a robust perennial thistle endemic to the highlands of central Mexico. It forms a stout, leafy stem rising from a thick taproot, typically reaching one to two metres in height. The deeply lobed, spiny-margined leaves are decurrent along the stem and bear a paler, often woolly underside. Flowering heads are large and showy, with a dense involucre of spine-tipped bracts surrounding numerous purple to reddish-pink disc florets; ray florets are absent. The fruit is a small achene crowned by a pappus of plumose bristles that aids wind dispersal. The species grows in temperate montane meadows, disturbed grasslands, and along roadsides, often at considerable elevation, and is well known in Mexican folk tradition under the name cardo Santo.
