In a medium saucepan, combine the fresh blueberries and water.

Bring the mixture to a gentle boil over medium heat and simmer for about 10 minutes.

Using a spoon or potato masher, lightly mash the blueberries in the saucepan.

Remove the saucepan from heat and strain the mixture through a fine mesh sieve into a teapot or heatproof pitcher.

Add the tea bags to the strained blueberry liquid and let them steep for 5 minutes.

Remove the tea bags and stir in the honey or sweetener of your choice.

If desired, stir in the lemon juice.

Pour the blueberry tea into cups and enjoy it hot, or chill it in the refrigerator for a refreshing iced version.
