Oregano, an herb commonly used in pasta and pizza sauces, has long been known to possess a variety of antibacterial and anti-inflammatory effects, but a new study by researchers at Long Island University (LIU) indicates that an ingredient of this spice, carvacrol, could potentially be used to treat prostate cancer, the second leading cause of cancer death in American men.
Dr. Supriya Bavadekar, PhD, RPh, Assistant Professor of Pharmacology at Long Island University, is currently testing carvacrol on prostate cancer cells. The results of her study demonstrate that the compound induces apoptosis in these cells. Apoptosis is programmed cell death, or simply "cell suicide." Bavadekar and her group are presently trying to determine the signaling pathways that the compound employs to bring about cancer cell suicide.
"We know that oregano possesses anti-bacterial as well as anti-inflammatory properties, but its effects on cancer cells really elevate the spice to the level of a super-spice like turmeric," said Bavadekar. Though the study is at its preliminary stage, she believes that the initial data indicates a huge potential in terms of carvacrol's use as an anti-cancer agent. "A significant advantage is that oregano is commonly used in food and has a 'Generally Recognized As Safe' status in the US. We expect this to translate into a decreased risk of severe toxic effects."
"Some researchers have previously shown that eating pizza may cut down cancer risk. This effect has been mostly attributed to lycopene, a substance found in tomato sauce, but we now feel that even the oregano seasoning may play a role," stated Bavadekar. "If the study continues to yield positive results, this super-spice may represent a very promising therapy for patients with prostate cancer."
The results of the study were presented at the Experimental Biology 2012 poster session on Tuesday, April 24.
