Place ingredients in a food processor or blender and puree. Add one cup water and refrigerate at least one hour.
At least one hour before serving, strain through a fine sieve (or coffee filter). Discard leaves. Add 3 1/2 to 4 cups water (to taste). Refrigerate. Serve over ice with mint leaves and lime slices.
Variation: Use Sprite or Seven-up instead of water & sugar as the mixer. Add Lime juice to taste (it can be a little sweet otherwise)
