Benefits and Effects

Parsley (Petroselinum crispum) contains the following Flavanoids: Apigenin, luteolin, Chrysoeriol, Quercetin, and Isorhamnetin. A Flavanoid is a phytonutrient and a powerful antioxidant found in plants.

  • A study by Zhang, Chen, and Wang (2006) using 14 participants found that parsley greatly increased their physiological antioxidant functioning, seen also in the seed’s oil.
  • In addition, Tunali, Yarat, and Yanardag, (1999) found improved blood glucose levels and reduced oxidative damage in the heart, notably the aorta tissue.
  • Reduced reproductive toxicity, significantly increased sperm count/motility and testosterone level, reduced chromosomal abberations, a diuretic effect, and inhibition of Na + -K+ ATPase activity (Kreydiyyeh & Usta, 2002).
  • “Hot and cold water extract from pseudomonas crispum leaves demonstrated antibacterial activity against pseudomonas aeruginosa, S. aureus and S. pyogenes isolated from patient with burn infection, demonstrated inhibitory activity against E. coli, L. monocytogenes, Erwinia carotovora, and Listeria innocua and no inhibition against Pseudomonas fragi. Psoralen, 8-methoxypsoralen, 5-methoxypsoralen, oxypeucedanin and isopimpinellin were among the responsible antimicrobial furocoumarins” (p. 824). Also showing anti-platelet, anti-coagulant, spasmolytic, and analgesic effects (Kreydiyyeh & Usta, 2002).
  • Success on treating otitis, sniffle and flu may be related to its antimicrobial and immunomodulatory activity (Kreydiyyeh & Usta, 2002).
