Hibiscus and rose hips should be taken in tea. They come in tea bags in healthfood stores or as loose tea from herbalists. In Italy you can buy dried whole hibiscus flowers and you can add 2-3 to a cupful of boiled water.
You can make these teas in summer, cool them and add sliced fruit such as strawberries, raspberries or peaches. You can chill them and then enjoy them.
Herbs like mint, cloves or cinnamon will also enhance the taste. Cinnamon too is very good for treating a cold.
