Dysphania ambrosioides (L.) Mosyakin & Clemants

Dysphania ambrosioides (L.) Mosyakin & Clemants (= Chenopodium ambrosioides L.) is an American aromatic species used as medicinal and culinary purposes since pre-Columbian times by Aztecs and Mayans in Mesoamerica (where is called epazote) and Andean communities and many others in South America (where is better known as paico). Currently, it is globally known by a wide diversity of cultures around the world, due to its cultivation and naturalization. Its uses are currently widespread in pluricultural contexts, by means the commercial circuits and mass media, especially the Internet. The main active constituents are essential oils, to which owes its aroma and flavor. It is toxic in high doses, but safe if is consumed in appropriated concentrations. The most widespread folk therapeutic use is as antiparasitic (anthelmintic, antimicrobial), and it is also employed against gastrointestinal disorders, as hypotensive, antipyretic, vulnerary, analgesic, anti-inflammatory, antitumor, sedative and anxiolytic, among others, many of which have been evaluated scientifically. The researches on its anticancer activity are very promising.Fil: Hurrell, Julio Alberto. Universidad Nacional de La Plata. Facultad de Ciencias Naturales y Museo.
