Xanthium strumarium - a potential cheap resource of plant substances for medicinal use

Xanthium strumarium L. (Asteraceae) is an annual herb which reproduces solely by seed. So far its centre of origin was considered Central or South America. Recent archeological research revealed that the burs of X. strumarium were used in Yuergou site (400-200 cal BC) in the Turpan Basin of northwestern China. This plant adventive to Europe reduces germination of various crops and behaves like and aggressive invasive species. X. strumarium is the most frequently recorded plant in the field borders between the crop land and adjacent territories the agricultural areas in Bulgaria. We aim of this study is to reveal the potential of X. strumarium as a cheap source of compounds with valuable pha…
