Clears Liver and Gallbladder Heat — jaundice, cholecystitis, hepatitis, and Damp-Heat accumulation in the Liver-Gallbladder axis
Clears Heat and resolves toxicity — febrile illness, high fever, and hot toxic swellings
Dispels Wind-Heat and releases the exterior — common cold with fever, headache, and throat pain
Moves Blood and stops pain — Liver-Qi stagnation with Blood stasis causing hypochondriac pain and gallbladder distension
Secondary Actions
Tibetan plateau folk use for respiratory conditions — cough and Lung heat patterns in highland alpine medicine traditions of Qinghai and Gansu
Antispasmodic — used in traditional northwest China folk medicine for smooth muscle spasm in the biliary and gastrointestinal tract
Classical References
Qinghai Zhong Cao Yao (青海中草药; Qinghai Medicinal Herbs): documents Gan Qing Qing Lan (甘青青兰, 'Gansu-Qinghai Dracocephalum') as a principal Liver-Gallbladder Heat-clearing herb of northwest China and Tibetan plateau folk medicine; used for jaundice, cholecystitis, hepatitis, and febrile illness; endemic to the high-altitude grasslands and rocky slopes of Qinghai, Gansu, and northwest Sichuan
Si Bu Yi Dian (Tibetan medical canon): Dracocephalum species are used in Sowa-Rigpa medicine for liver and gallbladder inflammatory conditions, fevers, and bile disorders; the 'tangut' designation refers to the Tangut ethnopolitical region encompassing the Xixia Kingdom territory (modern Qinghai-Gansu border highlands)
Modern Research
Active Compounds
Luteolin, apigenin, and acacetin (flavonoids; anti-inflammatory, antioxidant, antispasmodic)
Scutellarein and scutellarin (flavone glucuronides; anti-inflammatory, hepatoprotective — characteristic of Lamiaceae)
Rosmarinic acid (phenylpropanoid ester; anti-inflammatory, antioxidant — the principal phenolic acid of aromatic Lamiaceae)
Essential oil: caryophyllene, linalool, limonene, and monoterpene hydrocarbons (antimicrobial, spasmolytic)
Caffeic acid and chlorogenic acid (phenolic acids; antioxidant, anti-inflammatory)
Studied Effects
Anti-inflammatory: rosmarinic acid and scutellarein from Dracocephalum tanguticum inhibit NF-κB and COX-2 in LPS-stimulated macrophage assays and reduce carrageenan-induced paw edema in rodent models; hepatic anti-inflammatory activity was specifically demonstrated in Concanavalin A-induced liver injury models — validates the Liver-Gallbladder Heat-clearing and hepatoprotective folk applications
Antispasmodic and choleretic: flavonoid fraction from D. tanguticum relaxes isolated biliary smooth muscle and increases bile flow in perfused liver preparations; luteolin and apigenin have well-documented Ca2+-channel blocking spasmolytic activity in intestinal and biliary tissues — consistent with the traditional gallbladder pain and cholecystitis applications
Antimicrobial: essential oil from D. tanguticum shows inhibitory activity against common respiratory and gastrointestinal pathogens including Staphylococcus aureus, Streptococcus pneumoniae, and Helicobacter pylori in disc-diffusion assays — supports the fever and throat infection folk uses in Tibetan and northwest China medicine
Safety & Interactions
Contraindications
Spleen-Stomach Deficiency Cold — cool-bitter nature impairs digestive Yang; contraindicated with chronic loose stools and cold abdomen
Cold-pattern jaundice (cold body, pale stools, no thirst) — cool herb will worsen Yang deficiency jaundice
Cautions
Standard dose: 6–15 g dried herb in decoction
Limited formal pharmacokinetic and clinical safety data for this specific species; considered safe at traditional doses based on regional Tibetan and northwest China folk use
Pregnancy: cool-bitter Lamiaceae herbs traditionally used with caution in pregnancy
