Horseweed Benefits

The whole plant contains tannin, resins, flavonoids, gallic acid, and choline, besides an essential oil (oil of fleabane), which consists of limonene, dipentene, and terpineol. The horseweed has the following properties.

  • Hemostatic: It is mainly used to stop excessive or prolonged menstruation. It is also effective in some cases of hematuria (blood in the urine). It is worth remembering that a physician must check out any abnormal bleeding.
  • Antidiarrheic: It stops simple diarrhea but is also helpful for dysentery (diarrhea, accompanied by mucus and blood) and typhoid fever.
  • Diuretic and antirheumatic: The plant aids the elimination of uric acid in the urine, thus is recommended for gout, hyperuricemia (excess of uric acid), and kidney lithiasis (kidney stones).
