Contained certain substances that can kill cancer cells
Drinking tea regularly had always 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.
Mechanism of action of black tea in the fight against cancer cells is also evident in two recent studies experts. In the first study, researchers from New Jersey to evaluate the the aflavins-2 (TF-2), the unique compounds in black tea, and showed that the compound may kill cancer cells. This process is called apoptosis.
"The study was conducted to determine the mechanisms that made TF-2 to induce death of cancer cells including the effects of inflammation. It is known that inflammation can occur as a contributor in the development of mechanisms of cancer cells," says Dr. Tim Bond of the Tea Advisory Panel, quoted from Female First.
TF-2 substance 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 enzyme cyclooxygenase 2, while reducing the activity of the molecules that cause inflammation.
Substance TF-2 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 breast cancer in female mice.
"Polyphenols from green and black tea both to reduce the tumor as much as 77 percent and reduce risk as much as 92 percent growth," Bond said.
Both black tea and polyphenols in green tea can elaborate as much as 69 percent of reactive oxygen. Including inhibiting inflammation as much as 72 percent.
However, according to Bond, the invention still requires clinical trials. Namely to evaluate the effects of black tea and its components on cancer risk in humans.
