Active compounds

Flavonoids flavone-C-glycosides (baicalin, baicalein, wogonin)

Baicalin (baicalein-7-O-glucuronide)

Flavone glucuronide · Anti-inflammatory, antiviral, neuroprotective, anxiolytic

COX-2, PLA2 inhibition; blocking viral replication; GABA-A modulation; NF-κB inhibition · 9-13% in root (Huang Qin / Scutellaria baicalensis)

Baicalein

Flavone (baicalin aglycone) · Anti-inflammatory, antitumor, anxiolytic

5-LOX inhibition, tumor kinase (EGFR) inhibition, GABA modulation · 1-5%

Wogonina

Methoxylated flavone · Anxiolytic, anti-inflammatory, antitumor

Positive modulation of GABA-A (benzodiazepine) receptors, selective apoptosis in tumor cells · 0.3-2%

Oroxylin A

Methoxylated flavone · Anti-inflammatory, neuroprotective, antitumor

NF-κB inhibition, STAT3; G1 cell cycle block · 0.5-1.5%

Harvesting and processing

Harvest
Spring (March-April) or autumn (October-November), 3-4 year old plants

Roots harvested in spring before sprouting or in autumn after the plant dries out. Plants from Shanxi and Gansu have higher baicalein content. The outer cortex and fine secondary roots are removed.

Raw (生黄芩 Shēng Huáng Qín)

Root cleaned, softened with water to cut without breaking, sliced and dried. Softening should be brief to avoid loss of soluble baicalein. Standard shape.

Fried with wine (酒黄芩 Jiǔ Huáng Qín)

Slices sprinkled with yellow wine (10 ml per 100 g) and fried over medium heat. The wine reduces the extreme coldness of the grass and directs it towards the upper Lung.

Charred (黄芩炭 Huáng Qín Tàn)

Slices fried over high heat until charred on the outside, keeping the interior brown. Enhances hemostatic action.
