Popular
in china and other asian countries for thousands of years, green
tea has been shown to have significant medicinal as well as therapeutic
properties. Like the black tea more familiar in the western countries,
green tea comes from the camellia sinensis plant. The difference
between black and green teas lies in their processing. Black tea
is fermented, whereas green tea, which is prepared from steamed,
dried leaves, is not allowed to ferment. Also, some types of green
tea are lightly roasted. The minimal processing helps retain the
tea's green color, gives it a flowery aroma and fresh flavour and
also preserves the active ingredients that produce the tea's health
benefits. Green tea may help prevent tooth decay, high blood pressure,
heart disease and several forms of cancer. It also invigorates the
body and improves concentration.
Preparation
of the tea
Place 1 rounded
tsp. of tea leaves per cup in a teapot. Heat the water until it
is slimmering (160 deg F); cool briefly (vigorously boiling water
can destroy the tea's gentle flavour). Pour the water over the tea
leaves; cover the pot. For a mild flavour, let the pot stand 2-3
min; for a stronger flavour, steep for 4-6 min.
Warning: contains high caffeine content
Therapeutic
effect
All tea leaves contain caffeine, tannins, essential oils, polyphenols,
vitamins, minerals and trace elements (such as fluoride). Green
tea has many health benefits. It is an anti-inflammatory; lowers
blood cholesterol levels, has a beneficial effect on the circulation
and liver; protects against tooth decay and detoxifies the blood.
The active
ingredient caffeine
While green tea is highly touted for its health benefits, it does
contain a high level of caffeine. Depending on how long it brews,
a 6 oz. cup of green tea has 10-50 mg. of caffeine. While this stimulant
improves concentration and boosts alertness, it also increases the
heart rate and could keep you from getting a good night's rest.
The
trace element fluoride
The fluoride found in green tea hardens tooth enamel and makes teeth
more resistant to decay. Do not give tea to infants, however, because
it may inhibit iron metabolism.
Take
care : Too much caffeine can increase
your heart rate, restlessness and insomnia. To lower the caffeine
content of green tea, pour a little water over the leaves prior
to infusion and strain the water off after 30 seconds. Then prepare
the tea as usual.
Indications
For menopause
Vitamin and mineral needs increase during menopause. Daily consumption
of green tea can supply woman with the extra nutrients.
Giving up
coffee
If you are trying to refrain from that daily java, consider switching
to green tea. It has a smoky and bitter flavour that coffee drinkers
enjoy and the caffeine content, which is less than coffee, will
keep away the caffeine withdrawl headaches.
For athletic
performance
Cold green tea is an ideal thirst quencher. Its stimulating effect
and high concentration of vital substances increase mental and physical
performance during exercise.
For fasting
and detoxification
Known in China as a fat-melter, because of its cholesterol lowering
effects, green tea contains no calories and is recommended nutritional
supplement.
Cancer Prevention
According to scientific studies, compounds called polyphenols in
green tea may inhibit the growth of cancer cells and the development
of tumours. The benefit of these compounds is generally attributed
to their antioxidant activity. Several cups of green tea per day
are needed to enjoy this benefit.
