Green Tea May Prevent Large Kidney Stones

Here is another benefit attributed by the scientists to the "miracle drink" of our times: green tea.

According to a report published in the Royal Society of Chemistry journal CrystEngComm, drinking green tea may prevent formation of large kidney stone by altering the shape of the calcium oxalate crystals. Green tea's active component phenol has been shown to flatten the calcium oxalate crystals and thus prevent the formation of large kidney crystals. The smaller stones can be passed much more easily and painlessly through urine.

The image below shows the flattening process attributed to green tea consumption.
