I usually prefer to combine remedies myself for cleanses, this way you get products that are more appropriate for you.
For the liver: Boldocynara or Milk thistle from A.Vogel. Do one bottle every spring and fall.
For the kidneys: Stinging Nettle helps the kidneys flush out acids more efficiently but drink a lot of water with it for better results.
For the colon: Molkosan for fairly regular transit.
Half a lemon freshly squeezed in a cup of hot water every morning helps the liver eliminate toxins.
A few ounces of fresh carrot juice also help the liver.
Good breathing techniques that use the diaphragm help massage and oxygenate the liver.
