Abstract

Most of the people think that weeds are not useful, so they should be eradicated in any case. However weeds have numerous secondary metabolites of medical utility. These secondary metabolites serve as a treatment for many psychological, physical and pharmacological disorders of human body. The essential oils (EOs) extracted from weeds could be utilized as aromatherapy to cure several ailments. This review highlights the role of EOs in aromatherapy, health benefits of aromatherapy by essence or EOs of weeds, methods to extract aroma or EOs, their mode of action, quality and storage issues of EOs, scope and future trends in aromatherapy.
