The genus Bidens of Asteraceae family comprises around 230 species. Beggarticks, Spanish needles, blackjack, burr marigolds, stickseeds, tickseeds, and tickseed sunflowers are some of names of the plants. The genus has a wide distribution, but the systematics and taxonomy have been described as complicated and disjointed. Plants are annual or perennial shrubs or herbs, known for their diverse phenolic compounds that significantly influence their pharmacological properties. These compounds include flavonoids, phenolic acids, and tannins, which have strong antibacterial, antioxidant, and anti-inflammatory properties. Bidens species contain flavonoids with potent anti-inflammatory and anticancer effects, such as luteolin and glycosides. Phenolic acids, such as caffeic acid and its esters, help protect plants from stress-induced diseases. Bidens has little research on its tannins, which have astringent and antibacterial properties and have medicinal potential. The bioactive components of Bidens species have the potential to be therapeutically useful, and this chemical heterogeneity supports this possibility (diverse genus of weedy herbs). Popular names used for the fruiting bodies of these plants include beggarticks, blackjack, burr marigolds, cobbler’s pegs, Spanish needles, stickseeds, tickseeds, and tickseed sunflowers. The majority of the fruits have bristles and barbs on them. The derived name Bidens, which refers to the relative distinguishing traits, comes from the Latin concepts bis (“two”) and dens (“tooth”).
