How to Make It
In a small saucepan, bring 4 cups of water to a boil. Remove from the heat and add the goji berries, hibiscus flowers and Schisandra berries. Let stand at room temperature for 1 hour. Strain the tonic through a fine-mesh sieve set over a large jar. Whisk in the honey and rosewater, cover and refrigerate until chilled, about 1 hour. Serve warm or, if desired, over ice topped with sparkling water or wine.
