Turmeric is a spice that has been traditionally used in Ayurvedic medicine for various health benefits. However, there is no scientific evidence that turmeric can prevent or treat kidney stones. In fact, turmeric supplements may increase the risk of kidney stones in some individuals, particularly if they have a history of kidney stones or other kidney problems. This is because turmeric contains oxalates, which can contribute to the formation of kidney stones. It is important to consult with a doctor before taking any supplement, particularly if you have a history of kidney stones or other kidney problems.
