Two years ago, a University of California, Los Angeles, team generated other data suggesting that curcumin may be able to treat and prevent Alzheimer's disease. And three years ago, pediatricians at the Yale University School of Medicine showed in animal studies that curcumin can correct a defect associated with a chloride channel in cells that causes the most common form of cystic fibrosis.

"Even with existing free curcumin, we're seeing very encouraging results," says Bharat Bhushan Aggarwal, professor in the department of experimental therapeutics at the University of Texas MD Anderson Cancer Center and a cofounder of Curry Pharmaceuticals of Research Triangle Park, NC, which is developing curcumin-based drugs.

Over the past year, animal experiments at the Anderson center have demonstrated the efficacy of curcumin in its free form against tumors of the bladder, pancreas, ovaries, and brain.

Aggarwal and his colleagues have also tested curcumin in patients with lung cancer, pancreatic cancer, and multiple myeloma--a type of leukemia--with what he considers encouraging results. "We also know that even in high doses of up to 12 grams per day for several months, curcumin is very, very safe," Aggarwal says. In addition, his team demonstrated earlier this year that curcumin has the ability to enhance the antitumor effect of drugs used to treat pancreatic and bladder cancers.

Such promises notwithstanding, curcumin has yet to be more widely embraced by the medical community because its insoluble form demands high doses. "The single most important reason for the limited use of turmeric in human clinical trials is its poor solubility," Maitra says. Among other things, patients find the aftertaste of huge curcumin doses unbearable.

Now Maitra and his colleagues are about to begin new animal studies in which they will pit nanocurcumin against pancreatic cancer, cystic fibrosis, and Alzheimer's disease. "Nanocurcumin is expected to dramatically improve the clinical potential of this promising drug," says Maitra. And he says that someday, curcumin nanospheres could be decorated with special molecules that have an affinity for cancer cells, allowing the curcumin to home in on specific tumors.

    Isn't it possible to solubilize curucmin?  Doesn't look too hard.  Or does it lose it's effectiveness?

  • curcumin helps cancers
    I have been suffering from an acute skin cancer for years now and I have been trying to find something that would help it. I was watching “Know the Cause” one day and Doug Kaufman was talking about curcumin supplement and how it helps with people who has cancer and how it could also help prevent Alzheimer’s disease. So I decided to try it, I have been taking this product for almost 4 months now and it has help with my skin cancer. They have been clearing up on my skin. I definitely think this is a good product that actually works. I highly recommend it.

           Curcumin is hydrophobic, not disolveable in the water and not absorbeable in the blood stream. How can it cure? How quantity and quality can be used ?

        • Dose/Solubilizing curcumin and 2007 ASCO abstract with curucumin fights pancreatic cancers
          Curcumin can be solubilized by taking with fish oil or preferably enriched with fatty acids like DHA or omega 3 fatty acids (See Sally Frautschy at UCLA).

          Interesting abstract:

          Abstract: Background: Pancreatic cancer is virtually always lethal, and the only FDA-approved therapies- gemcitabine and erlotinib- produce objective responses in less than 10% of patients. Curcumin (diferuloyl methane) is a plant-derived dietary ingredient that suppresses NF-?B and numerous other pathways relevant to pancreatic cancer and has potent preclinical anti-tumor activity. Herein, we evaluated the safety and potential antitumor activity of curcumin against advanced pancreatic cancer, and its impact on biologic correlates. Methods: Patients received 8 grams of curcumin by mouth daily for two months and were then restaged. Maintenance therapy was continued at the same dose and schedule until disease progression. Results: Twenty-five patients were enrolled as of the date of analysis, with 21 evaluable for response. Circulating curcumin was detectable, albeit at low steady-state levels (about 31 ng/ml), suggesting poor oral bioavailability. To date, two patients have had prolonged stable disease (8 and 12+ months). Interestingly, one patient had a brief, but marked tumor regression (73%) (accompanied by significant increases (4-35-fold) in serum cytokine (interleukin-6 (IL-6), IL-8, IL-10, and IL-1 receptor antagonist (IL-1RA) levels). No toxicities have been observed. Curcumin down-regulated expression of NF-?B, COX-2 and phosphorylated STAT3 in peripheral blood mononuclear cells (PBMC) from patients (most of whom had baseline levels considerably higher than those found in healthy volunteers)although the decrease did not reach statistical significance for p65. Curcumin was determined in patient plasma samples after enzymatic digestion with glucuronidase enzyme. While there was considerable variation in plasma curcumin levels from patient to patient, drug levels peaked at 22-41 ng/ml and remained relatively constant over the entire 4 week experimental period. Conclusions: We conclude that oral curcumin is well tolerated and, despite its limited absorption, has biologic activity in patients with pancreatic cancer.

      • Re: curcumin helps cancers
        Hi,
        I ordered some curcumin 95% dry powder which I used for treating breast cancer. The powder could not be dissolved into water, so I just swallowed the dry powder with water. I was recommended by the manufacturer to take 8g of the dry powder  divided into two times daily. After viewing your information about the dry powder cannot go into the blood stream. Now what can I do for the dry powder ?  Is it less effective for curing cancer?
        Then where could I buy the nano-curcumin which can be easily absorbed by our body and can go to the blood stream, which obtain high potency of curing cancer?
        Thank you!
