Helping to keep the kidney's flushed and detoxified is an ongoing task.....the kidney's remove impurities and filter the blood; filtering about 150 quarts of fluid daily. Drinking plenty of water....an average of about 6 to 8 glasses a day is very beneficial, also drinking cranberry juice is great because it is a excellent source of vitamin C which helps dissolve kidney stones. http://www.merrittouch.com
