Drinking black tea could help prevent oral cancer, scientists have
said.

A study published in the Journal of Environmental Pathology, Toxicology
and Oncology revealed that chemicals in black tea called polyphenols
reverse cancer-causing changes to the DNA of cells lining the mouth,
reported science portal Scidev.

Researchers at the Vivekanada Institute of Medical Sciences in Kolkata,
monitored white patches called 'leukoplakia' in the mouths of patients
drinking black tea three times a day for one year.

The preliminary study conducted over 15 patients saw a remarkable
change in those white patches due to the intake of black tea. Even some
patches disappeared completely.

Generally half of the white patches in the mouth lead to oral cancer.

Although the findings relate to a small number of patients, lead
researcher Ajanta Haldar said: "The patches also disappeared in a
further seven patients who have completed the trial since publication
of the initial results."

Sixty more patients are being studied and will complete the trial by
April 2006.

The study funded by National Tea Research Foundation of India will
further assess whether the white patches reappear in patients who have
completed the yearlong trial and then ceased drinking black tea for six
months.

In 2002, oral cancer claimed 145,500 lives, two-thirds of which were in
developing countries. It is the most common form of malignant cancer
found in adult Indian men and the third most common in adult Indian
women.

Earlier scientists at the Memorial Sloan-Kettering Cancer Centre in the
US also found that polyphenol in green tea could slow the growth of
pre-cancerous mouth cells.

Researchers of the current study claimed that they are the first to
show a similar effect with black tea.

Another ongoing research by Madhumita Roy of Kolkata's Chittaranjan
National Cancer Institute shows that black tea combined with
anti-cancer drugs can force cultured human leukaemia cells to commit
suicide.

"This makes tea an ideal candidate to reduce the dose of anti-cancer
drugs by almost ten times, overcoming the toxic side effects of high
drug dose," Roy said.

What? Why doesn't that other currently popular antioxidant and anti-cancer
agent, curcumin, stop this? I assumed that would be quite heavily consumed
in India in curries.

It's also heavily consumed in America in hot-dog mustard.
