- Curcumin is promoted for anti‑inflammatory benefits against cancer, arthritis, hay fever, Alzheimer’s, menopause, and other ailments.
- Bharat Aggarwal published over 100 early‑2000s papers claiming curcumin kills tumor cells, sparking more than $275 million in U.S. health agency research funding and a surge in turmeric supplement use.
- Office of Research Integrity flagged at least 65 of Aggarwal’s papers for possible fraud in 2012; 30 of those papers have been retracted.
- Kathryn Nelson’s 2017 review concluded curcumin is unstable, reactive, and poorly bioavailable, making it an unlikely drug candidate.
Why it matters: Consumers and supplement makers lose credibility as $275 million of public research funding yields little therapeutic progress, while investors and health agencies face scrutiny for backing a poorly bioavailable compound.
