For many generations in India, China and Japan, green tea has
been regarded to contain health-promoting components. Much
research has been made on the health effects of green tea and
its prevention of and stopping the progressing of a variety of
illnesses. Only 20% of the tea consumed worldwide is green
tea. The remainder is black, yet many polyphenols in green
tea contain more antioxidant activity than the well-known
Vitamin C and Vitamin E. The antioxidants found in green
tea may prevent and reduce severe cases of arthritis and
cancers.
Green
Tea May Prevent Oral Cancer
At a scientific conference in Washington DC,
1998, a team of Chinese scientists revealed that drinking green
tea improves pre-cancerous conditions of oral leukoplakia in
patients and proposed it may have counteractive effects in oral
cancer.
The study involved 32 patients, 12
females and 20 males ranging in ages 23-28 years old who had
oral mucosa leukoplakia (a pre-cancerous lesion of oral cancer).
For the six month study, these patients drank three cups of
green tea a day and applied a mixture of green tea and glycerin
directly to the lesion.
The result was that 38% of the
patients had a reduction in the size of a single lesion or in
the total size of multiple lesion by 30% or more. Although 59%
saw no changes at all, the development of cancerous cells
decreased considerably.
Although this study was limited in
time and size, these figures provide promising evidence on the
preventive effects of green tea on cancer.
Green
Tea May Prevent Rheumatoid Arthritis
A study in Cleveland in April 1999
by medical researchers reported that drinking four or more cups
of green tea a day might prohibit rheumatoid arthritis and
lessen the harshness of it in those currently suffering from it.
The study was directed onto mice with collagen induced
arthritis, which is comparable to rheumatoid arthritis in
humans. The mice that received green tea were less likely to
develop arthritis than the mice who were given only water. The
mice that were given green tea and still developed arthritis had
less severe forms of arthritis.
This study concluded that the
antioxidants found in green tea have cancer-preventing
properties as well as anti-inflammatory properties. Rheumatoid
arthritis is an inflammatory disease that causes pain, swelling,
stiffness, and loss of function in the joints. Green tea's
antioxidants may prevent or reduce the severity of these
symptoms.
Green
Tea as Cancer Preventive
Of the ongoing research done on green tea and
its beneficial properties, a remarkable study by Japanese
scientists of the Saitama Cancer Research Institute found the
delay of cancer onset with drinking green tea. The study showed
that in early stages breast cancer, the cancerous
cells spread significantly slower in women who drank five or
more cups of green tea a day. They also found lower recurrence
rate in these patients.
Green tea contains EGCG which is a natural obstructer
of TNF- (a gene expression which encourages cancer cells to
develop in surrounding tissue). EGCG has been proven to kill
cultured cancer cells without causing harm to surrounding
healthy cells. Green tea could be beneficial not only for
the prevention of cancer but also in the therapy and prevention
of other diseases.
