Bring 4 cups of water to a boil in a medium-sized saucepan.
Once the water boils, remove it from heat and add the tea bags. Allow the tea bags to steep for 5-7 minutes or until you achieve your desired tea strength.
While the tea is steeping, add the frozen peach slices and sugar to a blender.
Once the tea has steeped, remove the tea bags and pour the hot tea over the frozen peaches and sugar in the blender.
Blend the mixture until the peaches are completely pureed and the sugar is dissolved. Strain the peach-infused tea to remove any pulp or tea bag remnants.
Allow the peach-infused tea to cool to room temperature, then refrigerate until chilled.
Fill glasses with ice cubes and pour the chilled peach tea over the ice. Garnish with lemon slices and fresh mint leaves, if desired.
