Tea is the product of Camellia sinensis, a unique non-alcoholic drink that cares, cures and of course cheers. It does fascinating things for the human body. Tea is grown in the countryside in an ambience that is totally ecological, apart from being a renewable natural resource. Even the processing is basically natural despite inevitable technical infringements that have only speeded up the process rather than changing the basic concept. Although the therapeutic values of tea have been known for ages, current research, epidemiological studies and clinical evaluation have unequivocally established the superior abilities of tea compounds in preventing and curing a plethora of human diseases, some as dreadful as cancer. Interestingly enough, quality components of tea, coupled with its anti-oxidant properties, make tea a unique beverage. The purpose of this book is not to publicise tea, but create awareness of the multiple benefits of drinking tea.
