Exhibition reveals the benefits of tea to health

"Health Benefits of Tea", a new exhibition at the Science News Corner of the Hong Kong Science Museum, is now showing until March 31, 2006.

The exhibition featuring the ingredients and functions of tea, and the research findings by Dr Marcel Koo Wing-leung of the Department of Pharmacology of the University of Hong Kong, allowing visitors to understand more about the health benefits of tea.

Tea is the most popular drink worldwide and it is produced from the tea plant named Camellia sinensis. Once the young shoots are picked, they can be processed into different kinds of tea, which can be classified mainly into three groups according to their degree of oxidation or fermentation. Green tea has the minimal oxidation or fermentation, oolong tea is semi-oxidised or semi-fermented and black tea is fully oxidised or fully fermented. The major constituents of tea are catechins, which make up 30% of the weight of dry leaves.

According to Dr Koo's findings, tea can lower cholesterol, prevent atherosclerosis, reduce body fat, maintain body weight, inhibit Helicobacter pylori, fight ageing, improve memory, suppress bladder cancer and increase bone density. The experiment results also showed that the active ingredients, catechins, were present in sufficient quantities in a single cup of tea to produce a beneficial effect. Regular consumption of green tea, in particular, is proven to be safe and relatively inexpensive while significantly improving people's health.

The Science Museum is located at 2 Science Museum Road, Tsim Sha Tsui East, Kowloon. It is open from 1pm to 9pm from Monday to Friday, from 10am to 9pm on Saturdays, Sundays and public holidays and from 10am to 5pm on Christmas Eve and Lunar New Year's Eve.
