liver cleaners and kidney cleaners?

is there a drink or something that flushs/cleans the liver/kidney from the toxins and crap after a cycle or during a cycle or whatever..........

take thistle for the liver but i dont know about kidney. oh and you can usually go to a pharmacy and they will have herbs and stuff.....you can ask the pharmacist.

Cranberry juice is good for the kidney.

thank you:)
