Common weeds may help our health, this is the finding of a new study from the University of Georgia in the US.
Scientists found that some common weeds might be more important sources of new medicines than exotic tropical plants.
Scientists working in the Mexican state of Chiapas discovered that nearly all the medically important plants used by the Highland Maya grow as weeds not far from houses or villages. Investigators also discovered that approximately a quarter of the medicinalplants used by native North Americans are weeds. Weeds are usually classified as plants that establish themselves quickly and grow where other plants can not. Full findings are published in the Journal of Ethnopharmacology.
