Insight on Vernonia Plant for its Pharmacological Properties: A Review

Vernonia is a woody shrub of the family Asteraceae. Over 1500 species are distributed in tropical and subtropical regions of Africa and Asia. There are more than 54 species known to possess similar morphological features with the characteristic bitter taste. The pharmacological properties of different parts like seeds, leaves, and roots are well documented in folk medicine. They are rich in biologically active constituents such as alkaloids, phenolics, flavonoids, terpenoids, steroid tannins, and carotenoids having broad therapeutic activities like antiinflammatory, hypoglycemic, hyperlipidemia, antimicrobial, antitumor, antioxidative, antiproliferative, antihypertensive, hepatoprotective, etc. The present study summarizes and discusses the phytochemical profile, pharmacological properties, and toxicological effects of the Vernonia plant.
