Abstract

This paper compares the flavonoid biomarker content (baicalin, baicalein and wogonin) of eleven commercial tinctures derived from Scutellaria lateriflora aerial parts
(n=7) and Scutellaria baicalensis root (n=4). S. lateriflora tinctures are used by Western herbal practitioners to treat anxiety whereas S. baicalensis tinctures are used to treat inflammatory disease. It’s findings indicate that the wide variability in biomarker concentrations between commercial tinctures has important implications for the manufacturers of commercial tinctures, for herbal practitioners in the choice of tinctures and not least for pharmacology and clinical researchers.
