The overall growth habit is that of a perennial herb or small subshrub suited for temperate forest understories.
What is the geographical distribution of this plant?
This plant is endemic to specific mountainous regions within central and southern China. It is most frequently documented growing in the provinces of Hubei, Hunan, and Guizhou. These populations typically inhabit temperate forest environments located at moderate elevations. The species thrives in the moist, shaded conditions found along rocky slopes and near mountain streams. Such localized distribution patterns suggest that the plant is highly adapted to the unique microclimates of these subtropical highlands.
How is this plant cultivated?
This plant Scutellaria rehderiana requires well-draining, slightly acidic soil and a location that provides partial shade to full sun to thrive.
It is best cultivated in temperate climates where the soil remains moist but never waterlogged. Regular watering is essential during the growing season to prevent the root system from drying out completely. Mulching the base of the plant helps retain moisture and regulates soil temperature during seasonal shifts.
Once established, this species is relatively hardy and can be propagated through stem cuttings or seed sowing.
What parts of this plant are used medicinally?

According to a study published by "Journal of pharmaceuctical and biomedical analysis", Scutelariia rehderiana Diels (SD) contains a variety of chemical components including baicalein, wogonin, chrysin, oroxylin A 7-O-β-D-glucuronoside, pinocembrin, and baicalin. A total of 113 compounds were tentatively identified in SD through the use of UHPLC-Q/TOF-MS/MS. The concentration of baicalein, wogonin, chrysin, pinocembrin, and oroxylin A 7-O-β-D-glucuronoside was found to be higher in SD. Regarding bioactivity, SD exhibited prominent anti-inflammarotary activity by measuring the inhibitory effect on the release of NO from lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. However, the study noted that SD was less effective in this anti-inflammarotary activity compared to SG.
