Red ginseng is Panax ginseng root steamed until reddish-brown. Steaming changes the ginsenoside profile, so the steamed root has its own monographs and marker pattern.
Ginsenosides are the characteristic saponins of Panax ginseng. Measuring them individually shows marker content and helps confirm the species, since American ginseng (Panax quinquefolius) has a different pattern, with little or no ginsenoside Rf.
Yes. Powders, capsules, dry extracts and liquid extracts can be tested, and extracts are usually compared against their labeled ginsenoside content.
