Traditional Food Puts Chemotherapy To Shame, New Study Reveals

A traditional food plant that has been used for thousands of years to improve health and well-being, is finally being validated by science. The results? It may be far superior to a chemotherapy agent with deadly side effects and dubious efficacy.


A powerful new study published in Molecular and Cellular Biochemistryprovides evidence that a traditional food consumed in the tropics as vegetables — Morinda citrifolia (Noni) leaves — may be the ideal complementary therapy or functional food in the prevention or management of lung cancer.

Amazingly, the study found that an extract of Noni leaf was more effective than the chemotherapy drug Erlotinib at suppressing metastasized lung cancer in an animal model.

According to the study, lung cancer is the most lethal of all cancers by number worldwide, taking 1.4 million lives annually. About 80% of these lung cancer cases are classified as non-small-cell lung cancer (NSCLC), and conventional chemotherapy and/or radiotherapy is notorious for failing to kill them due to the phenomena of chemoresistance and radioresistance. The survival statistics using these outdated approaches are dismal:

“Chemotherapy and/or irradiation usually fail because NSCLC cells are intrinsically resistant to them. Chemotherapy is quite ineffective for advanced NSCLC patients with only 20–35 % response rate and a 10- to 12-month median survival”

One of the most common interventions used for lung cancer today, on the chemotherapy side, is the drug Erlotinib, but the drug has never been proven safe or clinically effective in a true placebo-controlled trial. It was approved by the FDA based on its ability to improve survival a few months when added to conventional chemotherapy only relative the use of chemotherapy alone. We reported on this all too common practice of eschewing rigorous evidence-based standards with another chemotherapy drug recently: ipilimumab costs 4,000 times more than then gold by weight; at best, it only improves survival time in malignant melanoma patients by a few months; and it has deadly side effects.

Clearly, safer, more effective, and more affordable alternatives are needed, and this latest study could open a much needed discussion on the role of natural substances in cancer prevention and treatment.

Noni Leaf Extract Superior To Chemotherapy In Two Experimental Models


The new study, titled, “Metastasized lung cancer suppression by Morinda citrifolia (Noni) leaf compared to Erlotinib via anti-inflammatory, endogenous antioxidant responses and apoptotic gene activation,” evaluated the macro and micro effects of Noni leaves on metastatized lung cancer development in both a cell and animal model compared with the FDA-approved chemotherapy agent Erlotinib. They used two types of lung cancer cells: A549 human alveolar basal epithelial lung cancer cells and mouse Lewis lung carcinoma cells.

In the cell model, the extract “inhibited the proliferation and induced apoptosis [programmed cell death] in A549 cells (IC50 = 23.47 μg/mL) and mouse Lewis (LL2) lung carcinoma cells (IC50 = 5.50 μg/mL) in vitro, arrested cancer cell cycle at G0/G1 phases and significantly increased caspase-3/-8 without changing caspase-9 levels. “  In essence, the Noni leaf extract effected changes consistent with what would expect in an excellent chemotherapy agent. 

Perhaps most notably, the Noni leaf extract exhibited no toxicity in normal MRC5 lung cells — something that chemotherapy and radiation are notoriously incapable of producing. Said less euphemistically, chemotherapy and radiation not only drive cancer into a more invasive state, but can transform non-malignant cells into a highly malignant phenotype, even inducing stem-ness, a type of cellular immortality that can spell a death sentence to those in which it is induced.

The study next tested the difference between Noni leaf extract and the conventional chemotherapy agent Erlotinib in a non-small cell lung cancer (NSCLC) mouse model. The mice were fed with 150 and 300 mg/kg M. citrifolia leaf extract and compared with Erlotinib (50 mg/kg body weight) for 21 days.
