Invasive alien species – potential cheap resources of plant substances for medicinal use

Some alien species demonstrate rather invasive behaviour. They have high tolerance of various habitat conditions and potent propagation ability. They not only over-compete the local vegetation but suppress the seed development of the native plants. In the newly invaded habitats they might not have suitable herbivores to control their populations. The only effective enemy might be Homo sapiens. Humans are known with their destructive power once an object has become significant for industrial utilization. The aim of this study is to review research data and reveal the potential of Ambrosia artemisiifolia L., Erigeron canadensis L., Xanthium strumarium L. and Dittrichia graveolens (L.) W. Greu…
