In a medium saucepan, over medium heat, bring the water, sugar and star anise pods to a boil. Remove the pan from the heat and add the tea bags. Allow the tea to steep and cool to room temperature, about 1 hour. Discard the star anise pods and the tea bags and whisk in the condensed milk. Pour into a large pitcher and refrigerate for at least 1 hour, or until ready to serve.
To serve: Pour the tea into 4 ice-filled glasses. Garnish with fresh mint leaves and serve.
