Where is it found?
This annual South American plant is native to Chile and is considered to be one of the most important medical plants by the Mapuche indigenous people of that nation ((Mabberley, 2008; Wilhelm de Mosbach, 1999). The plant is also found in southern Argentina (Toursarkissian, 1980). The common name canchalagua can be confusing, as it is also applied to other very different plant species (Schkuhria spp. and Pectis spp. - Asteraceae) in Peru (Sung, 1996; Soukup, 1980).
Parts of the plant used:
The whole plant, especially the stalks and leaves.

What is it used for?
Cachanlahue is a bitter-tasting tea used in Chilean traditional medicine for various ailments including diabetes, circulatory problems (especially hypertension), anorexia (loss of appetite), fever (this plant is sometimes used to substitute cinchona bark as an antipyretic), jaundice, stomach pain, liver and other gastrointestinal ailments, as a diaphoretic (to induce sweating) and for the treatment of blood disorders and rheumatism. Externally, the plant decoction is used as a hair wash for the treatment of alopecia (hair loss). Recently, the tea has been touted as a treatment for weight loss, although no clinical trials to confirm this are presently known (Quattrocchi, 2012; Berdonces, 2009).
