Cleansing Juice to try

I found this recipe on Dr Oz's site for his 48 hour weekend cleanse.  Although I disagree that a juicer is required, it looks worth a shot!  We will report back once we try it.  Have you tried it?

Kale, Pineapple and Ginger Detox Drink (Juicer required)This purifying beverage contains kale to cleanse the kidneys; pineapple, which has bromelain to aid digestion; and ginger to help stimulate bile flow in your gall bladder.

Ingredients:
1/2 cup pineapple
2 large cucumbers
1 bunch kale without stems (4 cups chopped)
1/2 lemon, squeezed
1/4 inch of ginger
1 bunch of mint (1/2 cup)
