The potential benefits of curcumin are not in question, says Sabinsa's Shaheen Majeed
MD Anderson Cancer Center is conducting an investigation into alleged research fraud by an influential natural products researcher, NutraIngredients-USA can confirm.

Bharat Aggarwal, PhD, from the Cytokine Research Laboratory at Department of Experimental Therapeutics at The University of Texas MD Anderson Cancer Center is alleged to have altered images in 65 published scientific papers.

The allegations relate to research published between 1999 and 2012 focusing on the potential anti-cancer effects of various natural products and ingredients, including curcumin, resveratrol, capsaicin, Lactobacillus reuteri​ and cardamonin.

Reproducible data

Dr Aggarwal is perhaps most well known for his work on curcumin, the natural pigment that gives the spice turmeric its yellow color.

The compound has increasingly come under the scientific spotlight in recent years, with research groups around the globe investigating its potential benefits for reducing cholesterol levels, improving cardiovascular health, reducing the risk of Alzheimer's, and potential protection against cancer.

Many of the potential anti-cancer benefits of the compound were elucidated by Dr Aggarwal and his group, which used Sabinsa’s Curcumin C3 Complex in many of the studies.

There are absolutely no allegations against Sabinsa, and Shaheen Majeed, the company’s marketing director, told NutraIngredients-USA that the potential benefits of curcumin should not be questioned by the recent allegations.

“Dr Aggarwal’s was not the only group within MD Anderson that did research on curcumin,”​ he said.

“Also, his findings were no different to any other findings about curcumin in other groups, universities and institutions around the world. He first reported the anti-inflammatory potential of curcumin and this has been reproduced elsewhere.”


An MD Anderson spokesperson confirmed to NutraIngredients-USA that a review is under way.

“MD Anderson takes an allegation of research impropriety seriously, and we use internal and regulatory processes to review any such matter that is reported. Until a review is complete, we are required to keep details confidential.”

According to the Houston Chronicle​, MD Anderson was notified of the fraud allegations by the Office of Research Integrity (ORI).

However, John Dahlberg, PhD, director of the Division of Investigative Oversight at ORI could not confirm to NutraIngredients-USA that ORI was also investigating possible research misconduct.

“The Privacy Act System of Records prohibits ORI from either confirming or denying that we are aware of or investigating any active case,”​ he said.

Resveratrol research scandal

The MD Anderson research scandal is the second of 2012 involving natural product researchers, following the accusation by the University of Connecticut​ that Dr Dipak Das, a longtime researcher of the red wine compound resveratrol, fabricated data on at least 145 occasions, in 26 research papers published in 11 journals over seven years.

The University had taken part in a three-year investigation before going public in January​ with its allegations that Dr Das enagaged in systematic alteration of a type of data called Western Blot images which plot data - usually by Photoshop manipulation on his computer.

The allegations were refuted on the grounds of a racist conspiracy by Dr Das, but aside from a statement from his lawyer, he has remained largely silent on the affair as he recovers from a heart complaint in India.

More than 100 papers under investigation

Posted by Virgil,

The link above to the blog alleging fraud only includes 65 articles. There are actually more than 100 under investigation, spanning multiple different co-authors and 10 years of research. Another blog ( has even more examples of alleged image fraud in his papers.

Aggarwal has been pressed on multiple occasions (e.g. by journalists and by the Retraction Watch blog) to defend himself against these claims, and has so far failed to explain anything, other than nefarious "its all a conspiracy against me" nonsense. If the claims are not real, he should give EVIDENCE to the contrary, that is how science works!

As for the human fall out, CLINICAL TRIALS have been performed based on Aggarwal's work (just see the MD Anderson website, or search for "curcumin and cancer"). Who knows how many poor cancer patients were given false hope or even died as a result of this fraud.

Aggarwal has also received millions of dollars of NIH research grant money to do this research. As a fellow scientist, it saddens me deeply to see research grants becoming increasingly difficult to obtain, and all the while there are people like Aggarwal and Das out there defrauding the system of millions.

As for Bill Sardi (see comment on this page), he has financial ties to Das, and runs a company that sells resveratrol, the compound that Das worked on. Can you say conflict of interest?

More false allegations against natural products researchers

The allegations against Dr. Das are false, and they are picking off natural products researchers one at a time. Dr. Aggarwal is award-winning researcher.
