Type 2 diabetes mellitus patients are at high risk for acute renal failure because drug therapies intended for the treatment of type 2 diabetes result in side effects.  A new study in Food Chemistry and Toxicology suggests that taking Korean red ginseng extract may may prevent acute renal failure induced by gentamicin and pharmacokinetic changes induced by metformin.  Y. K. Lee and colleagues from Dongguk University-Seoul in Goyang, South Korea conducted the study in rats.
