The simple or branched and coarse-haired stem lignified at the base. The alternate leaves are up to 5 centimeters long, narrowly obovate, dotted with glands, glabrous to rough-haired and roughly serrated. The basal leaves are more or less pinnate.
The yellow, very small cup-shaped part inflorescences are terminated, up to 15 centimeters wide cyme arranged total inflorescences. The outer bracts are arranged in a few rows and are 2 millimeters long and have a membranous edge. The bottom of the cup is curved. In each flower head there are four to five yellow ray florets, 1.5 to 2 millimeters long . The fruits are achenes without a fringe of hair.

The chromosome number is 2n = 18.
Occurrence
The distribution area covers the western Mediterranean including Portugal, Morocco and Italy. It is originally found in Morocco, Spain, the Balearic Islands, Portugal, France, Corsica, Sardinia, Italy and Croatia. Here the yarrow liver balsam is found on roadsides, on wasteland and in damp places.
use
The botanical species name ageratum (from Greek agératos: not aging) and the German common name indicate the old use as a medicinal plant for liver diseases. After the species was assigned to the genus of the yarrow, the genus name Ageratum, used by the ancient botanists, became free and was , quite arbitrarily, transferred to an American ornamental plant by Carl von Linnaeus . The species Ageratum houstonianum is also called common liver balm after its name was transferred , although it was never used as a medicinal plant itself. The drug was also called malvasia or herba agerati.
