Why Give Lespedeza Capitana To My Dog & Cat? Lespedeza capitata contains flavonoids that produce renal vasodilation and stimulate the renal parenchyma, increasing diuresis by reducing blood urea without disturbing the electrolyte balance. Studies in rats, rabbits, cats and dogs have shown that Lespedeza capitata has a diuretic action equal in potency to theophylline and theobromine, but of longer duration. In cats and dogs with liver and kidney failure, Lespedeza capitata eliminated oliguria and albuminuria, and significantly reduced blood urea concentration. Lespedeza is recommended for: - Stimulation of kidney function - Chronic kidney disease. - Reduction of uremia.
