In a large measuring cup, dissolve the honey (if using) in ½ cup of boiling water. Add the tea bag and allow to steep for 10 minutes.
At the end of 10 minutes, add ½ cup ice and allow the tea to continue to steep for 10 minutes.
Mix in the guava juice and lemon juice. Place a generous amount of ice in 1 large or 2 small glasses and pour the iced tea lemonade into them.
