The Stimulating Effects of Black tea and Green Tea

Title: The Stimulating Effects Of Black Tea And Green Tea

The effect of tea on your body depends largely by the growth
stage of the leaf, the brewing time, the amount of tea used and
a person's sensitivity to tea's ingredients.

The stimulating effect of a tea is mainly due to what is called
alkaloid caffeine which is then linked with tannin found in a
tea leaf.

Almost the entire amount of caffeine is dissolved during the
infusion within the first 1-2 minutes because caffeine dissolves
well in hot water. This is without the tannin.

This short brewing time results to a brew with a high level of
caffeine not related to tannin. If the tea is brewed for a
longer time about 4-8 minutes, the tannin as well as other
ingredients start to dissolve gradually. This results, however,
to a stronger brew.

Tannin has the ability to prevent or delay the caffeine from
being absorbed quickly in the stomach or intestines.

It has been found that this delayed effect can stretch the
cumulative effect of caffeine to 10-12 hours with frequent,
daily tea-drinking.

So, if you want a more stimulating effect of a black tea or
green tea, consider a short brewing time and if you only want a
slightly stimulating effect, have a longer brewing time.

The caffeine of a tea can be reduced by pouring a little boiling
water over the amount of tea to be used and then sieving this
off after half a minute.

When not consumed in excess, tea can have a stimulating effect
but not irritating unlike other beverage. This stimulating
effect does not raise blood pressure. However, an excess intake
of caffeine can cause an increase in blood pressure.

A recommended amount of tea to use is a maximum of one level
teaspoon per cup of tea leaves with a longer brewing time about
4-6 minutes. This can be consumed naturally without the use of
artificial sweeteners or sugar.

A tea left for a shorter time only results to a milder brew.
