Bring 3/4 cup water and 3/4 cup lemonade to a simmer in a small saucepan. Remove from the heat and add 1 citrus mint tea bag and 1 peach-flavored tea bag. Cover and steep for 3 minutes.
Discard the tea bags, add 1 tablespoon honey, and stir until dissolved. Add 1 drop peppermint extract if desired. Divide the tea between 2 mugs and serve immediately with a thin slice of lemon.
