Lemon Verbena Iced Tea

To make a gallon of tea:
Steep 1 cup lemon verbena herbal tea leaves in a quart of boiling water for 15 minutes.
This creates a concentrated liquor.
Strain, then transfer lemon verbena liquor to a large container and add 3 quarts cold water; cover and refrigerate for up to 3 days.
For a 2-quart pitcher, add half of the tea mixture.
Quarter 1 orange and 1 lemon.
Squeeze orange and lemon quarters into the pitcher.
Add mint sprigs for garnish.
To serve, pour over glasses of ice and add a sprig of fresh lemon verbena or mint and citrus slices to each.
