Purifying Support for the KidneysHealthy kidney function involves the filtration of waste products (including various minerals) from the blood, and the excretion of liquid waste through the urine. Primary kidney supporting herbs - such as gravel root, parsley root, and marshmallow root - have traditionally been used to aid normal fluid elimination and general genitourinary health, thereby helping to ensure the smooth passage of urinary waste through the urinary tract. Gravel root's flushing and cleansing action helps to rid the body of mineral waste.
