Rating (out of 5): 1

Parsley (Petroselinum crispum) has a long history of use in traditional herbal medicine, particularly for urinary tract health. Traditionally, parsley has been used as a mild diuretic and to "cleanse" the kidneys and bladder, which may be why it has been suggested in folk remedies to help with blood in the urine (hematuria). However, there is scant direct historical documentation specifically citing parsley as a remedy for hematuria, though it appears in texts for general urinary complaints, "gravel," and kidney stones. The rationale in traditional use is that by increasing urine flow and supporting kidney function, parsley might help clear irritants or minor causes of bleeding in the urinary tract.

From a scientific perspective, the evidence is minimal. Some laboratory studies show that parsley extracts have mild diuretic effects and may possess anti-inflammatory properties. However, there are no high-quality clinical trials or robust scientific studies directly supporting parsley's efficacy for treating blood in urine. Most references to its use for hematuria are anecdotal or based on traditional herbalist recommendations rather than empirical research.

In summary, parsley’s use for blood in urine is primarily justified by traditional practice and not by strong scientific validation. Anyone experiencing hematuria should seek medical evaluation, as it can indicate serious underlying conditions.
