Gentiana scabra
Perennial of Chinese mountains; root used in TCM to clear heat and dampness from liver and gallbladder channels — one of the bitterest herbs in TCM.
Long Dan (Gentiana scabra) is a bitter perennial herb from Chinese mountains, traditionally used in TCM to clear heat and dampness from the liver and gallbladder channels. Modern research supports its hepatoprotective, anti-inflammatory, and antimicrobial activities, attributed primarily to secoiridoid glycosides such as gentiopicroside and swertiamarin. It is commonly employed for conditions like jaundice, hepatitis, and digestive disorders, though clinical evidence remains limited (Level C).
The bitter principles (gentiopicroside, swertiamarin) stimulate bitter taste receptors (TAS2Rs) on the tongue and in the gastrointestinal tract, triggering vagal reflexes that enhance gastric acid secretion, bile flow, and gallbladder contraction. Gentiopicroside exhibits hepatoprotection by upregulating Nrf2/ARE antioxidant pathways and inhibiting NF-κB-mediated inflammation. Xanthones and loganic acid contribute to antimicrobial effects against Gram-positive bacteria and fungi by disrupting cell membrane integrity. Additionally, sweroside modulates AMPK signaling, improving glucose metabolism and reducing hepatic steatosis.
