Anyone heard of this one? According to PMID 19336901, it appears to be an extract from Cornus officinalis (common Name Japanese cornel dogwood tree) that the study claims is as effective as aminoguanidine in "ameliorating glucose-mediated metabolic disorders".
I'm not familiar with dogwood tree extracts, but I see that there are extracts of Jamaican dogwood on iHerb used as a sleep aid and a pain reliever.
