Urinary tract infections (UTIs) are among the most common infections, particularly affecting women more than men.1 They cause significant pain and discomfort, impacting daily life.

As antibacterial resistance continues to rise, there is a growing need for new antimicrobial agents, particularly those derived from herbal sourcesParsley, a well-known herb in folk medicine, has been traditionally used for various health conditions, including UTIs. This clinical trial evaluated the effects of parsley on treating UTIs, exploring its potential as an alternative or adjunctive therapy in the face of increasing antibiotic resistance.

The Study

Published in the International Journal of Medical Research & Health Sciences, the study involved 37 patients, predominantly females (90.9%), diagnosed with UTIs based on detailed medical histories, clinical examinations, urine analysis, and abdominal ultrasonography. 

Parsley capsules were prepared by air-drying parsley leaves and stalks for one week, then finely grinding them into a powder. Participants were given 500 mg capsules of parsley powder, taken twice daily for 10 days. Their symptoms and urine samples were retested after 14 days.

The Results

At the 14-day check-up, patients reported significant improvements in UTI symptoms, such as frequency, urgency, dysuria, suprapubic pain, and loin pain. Urine analysis parameters also showed substantial improvements, including reduced urine acidity, pus cells, red blood cells, crystals, and epithelial cells.

No serious side effects of taking parsley for UTI were reported during the trial.

What Does this Mean?

According to this study, parsley shows great potential as a natural remedy for UTIs, offering an effective alternative to traditional antibiotics, especially in an era of rising antibacterial resistance. 

The beneficial effects of parsley for UTI may be attributed to its diverse chemical constituents, including flavonoids, ascorbic acid, and carotenoids, among others.

Future trials are needed to study the individual medicinal compounds in parsley to develop new, plant-based antimicrobial agents. Such developments could revolutionize the treatment of UTIs and other infections, providing a natural and sustainable solution to a growing global health challenge.

Other potent herbs that may help tackle UTIs naturally are cranberriesuva ursi, and garlic.
