hi rachel : I use five different herbs , marshmallow root ,hydragea root, gravel root, golden rod, and uva ursi , I was able to purchase them at a health food store in town , I take 1/4 cup of each herb into 10 cups of water and boil it for about 15 minutes , let stand for a couple of hours , then strain and put into a container you will need to drink one glass of the mixture daily , you can save the strained herbs for one more batch , just throw them in a plastic bag a freeze , this is hulda clarks kidney cleanse recipe she recommends 4 to 6 weeks to do a good cleanse , I started to get a very bitter taste on the tongue at the start of the second week and found out that this is all the toxins exiting the kidneys ,and last about 2 more weeks ,so far so good ,I have been feeling much better this week .

you don't have to do a liver cleanse prior to doing a kidney cleanse , let me know if you need any more info on the cleanse
