Kidney stones can form from many causes, in which urate stones are directly related to uric acid levels in the blood.
When uric acid is high, urate crystals can precipitate in the urinary tract, causing stones and kidney damage.
According to international studies, about 2/3 of uric acid is excreted through the kidneys, so kidney function plays a decisive role in controlling the concentration of this substance.
When the excretion process is disrupted, the risk of kidney stones and gout will increase.
Purslane contains many beneficial biological compounds such as flavonoids, polyphenols, alkaloids, and omega-3 fatty acids.
The plant is also rich in vitamins A, C, E and essential minerals. These ingredients help lay the foundation for antioxidant, anti-inflammatory and metabolic effects.
A new study published in PubMed Central shows that purslane extract has the ability to inhibit the enzyme xanthine oxidase - an enzyme important in the uric acid production process.
When this enzyme is inhibited, the amount of uric acid produced decreases; the risk of urate crystal formation decreases.
A very new study in 2026 in PubMed showed that polysaccharides from purslane can reduce blood uric acid levels, increase the expression of urate transporters in the kidneys, and support more efficient uric acid excretion.
Kidney stones are not only a mechanical problem but also related to inflammation and tissue damage.
Purslane is considered a diuretic. Increasing urine output helps:
Limit mineral crystallization
Increase waste removal
Reduce the risk of stone formation
This mechanism is consistent with modern recommendations for kidney stone prevention.
From scientific evidence, purslane can support:
Reduce uric acid production
Increased kidney excretion
Reduce inflammation and protect kidney tissue
Limit the formation of urate stones.
These are important factors in preventing and supporting the treatment of kidney stones.
Purslane can be used to cook soup, boil or stir-fry, eat raw.
Reasonable dosage: 50-100 g/time; 2-3 times/week.
It should be processed lightly to retain the biological active ingredient.
Preparing dishes from purslane is only a nutritional support measure, not a treatment method. Effective kidney stones prevention and control need to be combined with drinking enough water, a reasonable diet and periodic medical monitoring.
