A natural extract derived from India’s neem tree could potentially be used to treat pancreatic cancer, according to a new study.

Scientists tested nimbolide, a compound found in neem leaves, against pancreatic cancer in cell lines and mice. The results revealed that nimbolide can stop pancreatic cancer’s growth and metastasis without harming normal, healthy cells.

“The promise nimbolide has shown is amazing, and the specificity of the treatment towards cancer cells over normal cells is very intriguing,” says Rajkumar Lakshmanaswamy, Ph.D., an associate professor in Texas Tech University Health Sciences Center El Paso (TTUHSC El Paso) Centre of Emphasis in Cancer.

In the study, Lakshmanaswamy and his lab observed that nimbolide was able to reduce the migration and invasion capabilities of pancreatic cancer cells by 70%; meaning the cancerous cells did not become aggressive and spread. And that’s promising, the researchers say. In humans, metastasis of pancreatic cancer to other regions of the body is the chief cause of mortality.

Nimbolide induced cancer cell death

Nimbolide treatments also induced cancer cell death, causing the size and number of pancreatic cancer cell colonies to drop by 80%. “Nimbolide seems to attack pancreatic cancer from all angles,” Lakshmanaswamy says.

The researchers stress that one of the most important findings is that nimbolide did not harm healthy cells in both the in vitro and in vivo experiments.

Postdoctoral researcher Ramadevi Subramani, Ph.D., explains: “Many people in India actually eat neem and it doesn’t have harmful side effects, which suggests that using nimbolide for pancreatic cancer will not cause adverse effects like chemotherapy and radiation typically do.”

While the results are promising, Lakshmanaswamy says there’s still a long way to go before nimbolide can be used to treat pancreatic cancer in humans.

The TTUHSC El Paso team plans to continue researching the anticancer mechanisms behind the plant extract. They’ll also study various ways to administer nimbolide to maintain its potency against pancreatic cancer.

    Where is it possible to buy the leaves extract containing nimbolide ?
    My father has a pancreatic cancer, he lives in France.
    Are some treatments (chimiotherapy) already ready to treat patients ?

    Thank you very much for your responses.
