Place the loose hibiscus leaves (and the cinnamon stick if you'd like) into the water in a large glass jar. Put the lid on and refrigerate overnight or for 8 hours.
Strain out the hibiscus tea leaves through a sieve.
Add maple syrup or coconut nectar and possibly some lime juice.
Serve in a glass filled with ice.
Notes
Hibiscus has emmenagogue effects, which promotes menstruation. If you are pregnant or trying to get pregnant, please avoid drinking hibiscus tea.
