Flower and fruit tea is generally made from pollution-free flowers and fruits such as tropical hibiscus flowers, grapes, apples, sour plums, rose flowers, papayas, mangoes, citrus peels, cornflowers, Roman chamomile, and roses. Flower and fruit tea can help treat colds, thanks to the active vitamin C it contains. Vitamin C enhances immunity and improves the body's ability to resist diseases. Drinking a cup of flower and fruit tea is essentially like drinking a fresh fruit juice. In Germany, it is often used as an adjunct to medication to aid recovery, believed to shorten the course of illness.
