Bring water to a boil (about 5-8 mins), turn off heat, and add the hibiscus flowers and cinnamon sticks. Cover and steep for about 15-20 minutes.
Strain tea into desired container and stir in sugar or honey to taste. Serve warm with lime wedges on the side. This tea can be served chilled instead. For this, add ice and orange or lime rounds.
NOTE: Do not steep tea for a longer time because it can become bitter. If its flavor needs to be strengthen, add more herbs but do not steep tea longer. Inactive prep time: 15-20 minutes. Yield: About 6 cups.
