Natural compounds found in herbs reduce cancer risk

thymeThe University of Missouri has released a new study specifying that natural compounds found in herbs and vegetables reduce the risk of breast associated with hormone replacement therapy.

The researchers examined the impact of luteolin, a natural compound found in herbs such as thyme and parlsey; and vegetables such as and broccoli.

Luteolin administered to human breast cells in the lab, reduced the number vessels “feeding” cells causing .

As human breast cells develop, they tend to take on stem cell-like properties, which can make them harder to kill. Luteolin was used to monitor stem cell-like characteristics of breast cells. Laboratory mice with breast also had reduced blood vessel formation and stem-like characteristics.

“In most circumstances, hormone replacement therapies improve the lives of menopausal women and achieve excellent results,” said Salman Hyder, the Zalk Endowed Professor in Tumor Angiogenesis and professor of biomedical sciences in the College of Veterinary Medicine and the Dalton Cardiovascular Research Center. “Nevertheless, research has proven that a higher incidence of breast tumors can occur in women receiving therapies that involve a combination of the natural component estrogen and the synthetic progestin”.

“Most older women normally have benign lesions in ,” Hyder said. “These lesions typically don’t form tumors until they receive the ‘trigger’– in this case, progestin–that attracts blood vessels to cells essentially feeding the lesions causing them to expand.”

“We feel that luteolin can be effective when injected directly into the , so IV supplements may still be a possibility,” Hyder said. “But, until the supplement is tested for safety and commercialized, which we hope will happen after further testing and clinical trials, women should continue a healthy diet with fresh .”
