I like making large batches of crysanthemum tisane. I make ice cubes and freeze for the summer months to add to my chilled tisane from the fridge. Although I prefer it sugarless in the summer, in the winter months I like to drink it hot with honey.
Prior to Sept-11, I used to bring either a thermos or a water bottle of it with me on the plane. I found that I didn't catch whaterever was going around as easily.
