Purslane is rich in water, potassium and antioxidants such as flavonoids, plant omega-3s. These ingredients can help increase urine output and reduce the crystallization of minerals in the kidneys, the main cause of stone formation. According to the US National Institutes of Health, a diet rich in potassium and antioxidants plays an important role in reducing the risk of calcium oxalate stone formation.
Notably, some studies published on the US National Biotechnology Information Center system show that purslane extract has a mild diuretic effect, supporting the elimination of waste through the urinary tract, and also helping to reduce inflammation in the urinary system.
Nutrition expert Dr. Sarah Brewer (UK) said that purslane is not only a food but also a "super herb" thanks to its high content of minerals and biological active ingredients. She believes that supplementing vegetables rich in potassium such as purslane can support mineral balance in urine, thereby reducing the risk of accumulation of stones.
However, experts also note that purslane is only supportive. For large or painful stones, patients need medical treatment. In addition, people with a history of oxalate stones should also use it at a moderate level because purslane contains natural oxalate.
