Alzheimer’s disease: Duke found more than 50 studies on turmeric’s effects in addressing Alzheimer’s disease. The reports indicate that extracts of turmeric contain a number of natural agents that block the formation of beta-amyloid, the substance responsible for the plaques that slowly obstruct cerebral function in Alzheimer’s disease.
Arthritis: Turmeric contains more than two dozen anti-inflammatory compounds, including sixdifferent COX-2-inhibitors (the COX-2 enzyme promotes pain, swelling and inflammation; inhibitors selectively block that enzyme). By itself, writes Duke, curcumin – the component in turmeric most often cited for its healthful effects – is a multifaceted anti-inflammatory agent, and studies of the efficacy of curcumin have demonstrated positive changes in arthritic symptoms.
Cancer: Duke found more than 200 citations for turmeric and cancer and more than 700 for curcumin and cancer. He noted that in the handbook Phytochemicals: Mechanisms of Action, curcumin and/or turmeric were effective in animal models in prevention and/or treatment of colon cancer, mammary cancer, prostate cancer, murine hepatocarcinogenesis (liver cancer in rats), esophageal cancer, and oral cancer. Duke said that the effectiveness of the herb against these cancers compared favorably with that reported for pharmaceuticals.
