Greater Bur Marigold
Bidens radiata
Bidens radiata, commonly known as horseweed, is a plant traditionally not associated with any specific medicinal use. Its traditional medicine applications have not been documented in historical or contemporary practices. Scientific evidence for Bidens radiata's medicinal properties is limited; one study indicated that it may exhibit growth inhibition and neotenic flowering under short-day conditions compared to long-day conditions. Additionally, research on related species showed variation in assimilating pigments, total polyphenols, and antioxidant activity influenced by copper salt type and concentration, but no significant leaf damage was observed. At the genetic level, Bidens cernua exhibited higher diversity than Bidens radiata var. pinnatifida or Bidens tripartita. No major safety concerns have been reported for Bidens radiata, nor are there any recorded drug interactions.

What the science says
- The study found that future climate scenarios showed expansion in suitable habitats for most Bidens species, except B. pilosa, B. maximowicziana, and B. radiata.
- Bidens radiata showed growth inhibition and neotenic flowering under short-day conditions compared to long-day conditions.
- The degree of genetic diversity at the species level was higher in Bidens cernua than in Bidens radiata var. pinnatifida or B. tripartita.
- The study found that Bidens radiata was among the exotic species cultivated at the manor farm Švamberk from the 17th century onwards.
- The amount of assimilating pigments, total polyphenols, and antioxidant activity in wheat plants varied depending on the copper salt type and concentration, with no significant leaf damage observed.
