A natural citrus fruit extract has been found to dissolve calcium oxalate crystals, the most common component of human kidney stones, in a finding that could lead to significantly improving kidney stone treatment, according to researchers at the University of Pittsburgh, the University of Houston, and Litholink Corporation, among which is Giannis Mpourmpakis.

In a study published Aug. 8 in the journal Nature, the researchers offer the first evidence that the compound hydroxycitrate (HCA) effectively inhibits calcium oxalate crystal growth and, under certain conditions, is able to dissolve the crystals. HCA shows “promise as a potential therapy to prevent kidney stones,” the researchers wrote.
