Effectiveness of use:
1. Atherosclerosis:Green tea may help prevent atherosclerosis, particularly coronary
2. High cholesterol:Results from one animal study suggest that polyphenols in green tea
may block the intestinal absorption of cholesterol and promote its
excretion from the body. In another small study of male smokers,
researchers found that green tea significantly reduced blood levels
of harmful LDL cholesterol.
3. Cancer:Green and black teas help protect against cancer. The polyphenols
in tea, especially green tea, may play an important role in the
prevention of cancer. Researchers also believe that polyphenols
help kill cancerous cells and stop their progression.
4. Inflammatory Bowel Disease (IBD):Green tea may help reduce inflammation associated with Crohn's
disease and ulcerative colitis, the two types of IBD. If green tea
proves to be helpful for preventing colon cancer, this would be an
added benefit for those with IBD because they are at risk for colon
5. Diabetes:Green tea has been used traditionally to control blood sugar in the
body. People with type 1 diabetes produce little or no insulin, a
hormone that converts glucose (sugar), starches, and other foods
into energy needed for daily life. Green tea may help regulate
glucose in the body.A few small clinical studies have found that
daily supplementation of the diet with green tea extract powder
lowered the hemoglobin A1c level in individuals with borderline
6. Liver disease:Green tea seems to protect the liver from the damaging effects of
toxic substances such as alcohol.
7. Weight loss:Clinical studies suggest that green tea extract may boost
metabolism and help burn fat. One study confirmed that the
combination of green tea and caffeine improved weight loss and
maintenance in overweight and moderately obese individuals. Some
researchers speculate that substances in green tea known as
polyphenols, specifically the catechins, are responsible for the
herb's fat-burning effect.
Tea consumption had its origin in China more than 4000 years ago.
Green tea is tea made solely with the leaves of Camellia sinensis
that have undergone minimal oxidation during processing. Green tea
originates from China and has become associated with many cultures
in Asia from Japan and South Korea to the Middle East. Recently, it
has become more widespread in the West, where black tea is
traditionally consumed. Many varieties of green tea have been
created in countries where it is grown. These varieties can differ
substantially due to variable growing conditions, processing, and
Over the last few decades green tea has been subjected to many
scientific and medical studies to determine the extent of its
long-purported health benefits, with some evidence suggesting that
regular green tea drinkers have lower chances of heart disease and
developing certain types of cancer. Although there is no scientific
evidence that plain green tea can produce weight loss, a green tea
extract rich in polyphenols and caffeine has been shown to be
useful for "obesity management", since it induces thermogenesis and
stimulates fat oxidation.
