Washington: An ingredient of Oregano, the common pizza and pasta seasoning herb, could potentially be used to treat prostate cancer, researchers including one of an Indian have found. This super-spice, studied by researchers at Long Island University (LIU), has long been known to possess a variety of beneficial health effects.

Prostate cancer is a type of cancer that starts in the prostate gland and usually occurs in older men. Recent data shows that about 1 in 36 men will die of prostate cancer.

Current treatment options for patients include surgery, radiation therapy, hormone therapy, chemotherapy, and immune therapy. Unfortunately, these are associated with considerable complications and/or severe side effects.

Dr. Supriya Bavadekar, PhD, RPh, Assistant Professor of Pharmacology at LIU's Arnold and Marie Schwartz College of Pharmacy and Health Sciences, is currently testing carvacrol, a constituent of oregano, on prostate cancer cells.

The results of her study demonstrate that the compound induces apoptosis in these cells. Apoptosis, Dr. Bavadekar explained, is programmed cell death, or simply "cell suicide."

Dr. 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 Dr. 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," she said.

"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 Dr. Bavadekar.

"If the study continues to yield positive results, this super-spice may represent a very promising therapy for patients with prostate cancer," she added. The results of the study were presented at the Experimental Biology 2012 poster session on Tuesday, April 24.
