Breakthrough Method to Get "Miracle" Anti-Inflammatory Spice to "Get Past Gut" Developed by Doctors

Scientific evidence suggests curcumin promotes health because it lowers inflammation, but it is not absorbed well by the body. Most curcumin in food or supplements stays in the gastrointestinal tract, [but this new] process allows the compound to dissolve and be more easily absorbed by the gut to enter the bloodstream and tissues.

Curcumin is a naturally occurring compound found in the spice turmeric that has been used for centuries as a... treatment for such ailments as allergies, diabetes and ulcers.

Anecdotal and scientific evidence suggests curcumin promotes health because it lowers inflammation, but it is not absorbed well by the body. Most curcumin in food or supplements stays in the gastrointestinal tract, and any portion that's absorbed is metabolized quickly.

Many research groups are testing the compound's effects on disorders ranging from colon cancer to osteoarthritis. Others, like these Ohio State University scientists, are investigating whether enabling widespread availability of curcumin's biological effects to the entire body could make it useful both therapeutically and as a daily supplement to combat disease.

"There's a reason why this compound has been used for hundreds of years in Eastern medicine. And this study suggests that we have identified a better and more effective way to deliver curcumin and know what diseases to use it for so that we can take advantage of its anti-inflammatory power," said Nicholas Young, a postdoctoral researcher in rheumatology and immunology at Ohio State and lead author of the study.

The research is published in the Nov. 4, 2014, issue of the journal PLOS ONE.

Curcumin powder was mixed with castor oil and polyethylene glycol in a process called nano-emulsion (think vinaigrette salad dressing), creating fluid teeming with microvesicles that contain curcumin. This process allows the compound to dissolve and be more easily absorbed by the gut to enter the bloodstream and tissues. (Photo via Wikipedia)

Feeding mice this curcumin-based drug shut down an acute inflammatory reaction by blocking activation of a key protein that triggers the immune response. The researchers were also the first to show that curcumin stops recruitment of specific immune cells that, when overactive, are linked to such problems as heart disease and obesity.

Young and his colleagues, including co-senior authors Lai-Chu Wu and Wael Jarjour of the Division of Rheumatology and Immunology at Ohio State's Wexner Medical Center, now want to know if curcumin in this form can counter the chronic inflammation that is linked to sickness and age-related frailty. They have started with animal studies testing nano-emulsified curcumin's ability to prevent or control inflammation in a lupus model.

"We envision that this nutraceutical could be used one day both as a daily supplement to help prevent certain diseases and as a therapeutic drug to help combat the bad inflammation observed in many diseases," Young said. "The distinction will then be in the amount given—perhaps a low dose for daily prevention and higher doses for disease suppression."
