Bur Marigold
Bidens cernua
Bidens cernua, commonly known as flat-top beggarticks or horseweed, is a traditional medicine with origins in North America. Its use in herbal remedies has not been extensively documented across various traditions. Scientific studies have shown that cerbiden, derived from Bidens cernua, exhibits high antifungal activity against several Candida species in vitro. Additionally, phenylheptatriyne isolated from the plant demonstrated significant antifungal activity against different yeast strains with minimal inhibitory concentrations ranging from 12.5 to 100 µg/ml. However, there is limited evidence regarding its efficacy for specific conditions or applications. Bidens cernua has been found to serve as a host for the nematode Meloidogyne hapla, but no significant differences were observed in phytoextraction processes involving other plants. No major safety concerns have been recorded, and there are currently no known drug interactions associated with this plant.
