Green Tea and Alzheimer's
EGCG Can Save Brain Cells

A breakthrough green tea and Alzheimer's study discovered that it regenerates damaged brain cells, bringing hope to millions of Parkinson’s and Alzheimer’s disease sufferers.

Many scientific research studies have shown that green tea fights bacteria, inflammation and reduces stress. Perhaps it would be an excellent candidate for treating acne?

For a long time, scientists thought that damaged brain cells were irreparable.

Feeding green tea extract to mice with Parkinson's and Alzheimer's disease protects brain cells from dying and even reverses the damage. This was found in a study conducted by Dr. Silvia Mandel of Technion Institute of Science in Israel.

Tea consumption is inversely correlated with the incidence of dementia, Alzheimer's disease and Parkinson's disease. Tea drinking Asians are less likely to suffer from age-related neurological disorders compared to Europeans and Americans.

The Study

But until now, nobody knew how green tea antioxidant – EGCG – works when it gets into the brain.

The green tea and Alzheimer's study conducted by Mandel solved the puzzle.

Dr. Mandel fed green tea extract, equal to 2 to 4 cups a day, to mice induced with Parkinson's disease. She found that EGCG prevented brain cells from dying, and reduced compounds that lead to lesions in the brain.

She presented her findings in Washington DC to a rapt audience of colleagues at the Fourth International Scientific Symposium on Tea and Human Health.

"It was received really well, and I was told there was extreme interest in it," said Mandel.

"More recently, a PhD student of mine - Lydia Reznichenko - conducted a "neurorescue" study that closely resembles what happens in humans - first the disease is diagnosed and then the doctors prescribe medication," said Mandel.

"We induced Parkinson's in mice and waited until the damage was evident. Then we began to administer the EGCG to the animals. The results showed that the EGCG not only prevented further deterioration, but it helped to regenerate the already damaged neurons in the brain.”

“This phenomenon is called neurorescue or neurorestoration, and we're the first to show that green tea is effective in doing this.”

“The major question is whether these promising results are reproducible in humans."

Exciting Breakthrough

"Researchers have been actively searching for better ways to support brain cell repair for many years," said tea and health expert Dr. Carol Greenwood.

"This finding that tea, a natural product consumed by millions of people every day, can help repair them is especially exciting."

The years of green tea and Alzheimer's research are beginning to pay off.

The Michael J. Fox Foundation is conducting tests in China on early Parkinson's patients to check whether green tea extract is slowing down the progression of the disease.

Mandel is so impressed by the healthful properties in tea that she drinks 4 cups a day.

"I try to drink at least 2 cups of green tea a day. And I like regular dark tea too, so I drink another 2 cups of that."
