Chanca piedra is a South American urinary-herbal name used for several Phyllanthus species. Herbalists traditionally prepare the leafy aerial herb as tea for urinary-stone concerns. Research interest centers especially on identified Phyllanthus niruri preparations.
Traditional Uses & Why Herbalists Value It
Regional South American traditions steep Phyllanthus aerial parts in urinary teas. The Spanish name 'stone breaker' reflects this historical use. Identifying the species is essential because the name can refer to several traded plants.
What Modern Research Has Found
A small uncontrolled study of Phyllanthus niruri in adults with kidney stones reported changes in urinary mineral measures, including increased potassium and magnesium-related measures. The absence of a placebo group limits conclusions about benefit. The findings concern identified P. niruri material.
Plant Part, Preparation & Natural Constituents
The leafy aerial herb differs from root and from standardized extracts. Exact species remains important.
