| In a non-randomized, open-label, clinical trial involving 44 smokers with 8 or more ACF (aberrant crypt foci) on screening colonoscopy, administration of a 4 g dose of curcumin was found to be associated with a significant 40% reduction in ACF number, which was associated with significant, five-fold increase in post-treatment plasma curcumin/conjugate levels. A 2 g dose of curcumin did not yield such benefits. The authors conclude, "Our data suggest that curcumin can decrease ACF number, and this is potentially mediated by curcumin conjugates delivered systemically." | Reference: | "Phase IIa Clinical Trial of Curcumin for the Prevention of Colorectal Neoplasia," Carroll RE, Benya RV, et al, Cancer Prev Res (Phila), 2011 March; 4(3): 354-64.
