In a medium sauce pan, heat the 5 cups of water over high heat. Bring to a boil.

Remove the pan from the heat and add the three tea bags.

Allow the tea to steep for 5 minutes. Remove the tea bags and discard them. Allow the tea to cool another 5 minutes at room temperature.

Place the demerara sugar in your gallon pitcher. Pour the slightly cooled tea over the sugar and stir until the sugar is dissolved.

Fill up the rest of the pitcher with ice. Add the Lemon Vitality essential oil. Stir and serve over a full glass of ice.

If you'd like to add lemon slices as garnish, serve them in the individual glasses.
