Cancer-fighting substances in Tea


tea fight cancerDrinking tea regularly had always been believed to have a positive impact on health. Some studies reveal that compounds in tea can prevent the development of cancer cells in the body. Especially if you regularly consume black tea.

Work mechanism of black tea in fighting against cancer cells is also proven in two recent studies by experts. In the first study, researchers from New Jersey evaluated the theaflavins-2 (TF-2), the unique compound in black tea, and showed that the compound can kill cancer cells. This process is called apoptosis.

“The study was conducted to determine the mechanisms done bt TF-2 to induce death of cancer cells including the effects of inflammation. It is known that inflammation can occur as a contributor mechanisms in the development of of cancer cells,” says Dr. Tim Bond of the Tea Advisory Panel, according to Female First.

TF-2 substance are known to trigger cancer cell death by stimulating cell shrinkage within 3 hours of treatment. The study also showed the ability of TF-2 to suppress the activity of genes that induce the cyclooxygenase 2 enzyme, while reducing the activity of the molecules that cause inflammation.

TF-2 substance also produce the pattern of gene regulation that are similar to those found in cancer cells. The results showed that TF-2 is a major component in black tea that can kill cancer cells through a mechanism of gene regulation and may reduce inflammation.

In the second study, researchers from India examined the effects of polyphenols from black tea and green tea related to breast cancer in female rats.

“Polyphenols from green and black tea are good to reduce the tumor as much as 77 percent and reduce growth risk as much as 92 percent,” Bond said.

Both black tea and green tea polyphenols can elaborate as much as 69 percent of reactive oxygen. Including inhibiting inflammation as much as 72 percent.

However, according to Bond, the finding still requires clinical trials. Namely to evaluate the effects of black tea and its components on cancer risk in humans.
