Calea ternifolia Kunth. - syn.Calea zacatechichi Schltdl.;Asteraceae
Mexican calea, bitter gras, Bitterkraut, Traumkraut

Annual herb, native to Central America.

Plant names of Mexican indigenous cultures (bitter gum, white bitter herb) point to the traditional use as remedy for stomach-ache.

The herb contains sesquiterpene lactones of the germacranolide type (responsible for the bitterness) and flavones.

„Calea zacatechichi yielded the sesquiterpene lactone zexbrevin and a new analog, several analogs of neurolenin B including calein A, two analogs of budlein A and the flavones acacetin and O-methylacacetin.“

„Caleine E and F, two new sesquiterpene lactones, were isolated from Calea zacatechichi.“
