Note that the effective amounts exhibiting biological activities for ar-turmerone are in the microgram/ml or mg/kg range. Since ar-turmerone is effective against snake bites and hemorrhage while also inhibiting inflammatory and pain prostaglandins, ar-turmerone shows unique promise in helping to treat a variety of diseases. The only source for this listed in the http://www.ars-grin.gov/duke database is turmeric. Any substance that slows tumor growth, such as the antiproliferant activity of ar-turmerone, gives the immune system a chance to catch and overcome the tumor. Although AntiNKC and antilymphocytic activities might be of some concern, diminished cell-mediated immunity would be expected if ar-turmerone dramatically improves humoral immunity.
