Why Ginger root/rhizome extract (unstandardized or ratio extract) is unrated

Extract mass on a label (a 4:1 extract, a supercritical CO2 extract, a dry aqueous extract) represents very different amounts of ginger, and no verified human study ranks extract types against each other or against powder.

Why Ginger root/rhizome powder (dried) is unrated

The 1.2-2 g/day diabetes meta-analysis cited on the compound used powder capsules, but no head-to-head human comparison of powder vs extract was found in this pass.
