Although most commonly thought of as a garnish for a meal, parsley is also a strong herbal remedy for a number of ailments. The rich concentration of vitamins A, C and C, in addition to various minerals and organic compounds, make parsley the perfect home remedy for kidney disease. Vitamin A and C are both antioxidant compounds that slow the progression of chronic disease, while minerals like copper and potassium improve renal system function. Finally, parsley is also a diuretic, which means it increases your frequency of urination, thus speeding up the release of toxins from the body.
