Long Dan Cao (Gentiana scabra) is a traditional Chinese herb containing gentiopicroside and swertiamarin that supports liver detoxification and reduces inflammation. These bitter compounds stimulate bile production and modulate inflammatory pathways through NF-κB inhibition.
Reported Benefits (Provisional)
Origin & History
Long Dan Cao is derived from the root of the Gentiana scabra plant, native to Asia. It is typically dried and used in herbal formulations.
Research Narrative (Provisional)
Studies have shown that Long Dan Cao may have anti-inflammatory and hepatoprotective properties. However, further research is needed to fully understand its benefits.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.

Reported Mechanism (Provisional)
Gentiopicroside and swertiamarin, the primary iridoid glycosides in Long Dan Cao, stimulate bile acid synthesis and enhance hepatic cytochrome P450 enzyme activity for improved detoxification. These compounds inhibit NF-κB signaling pathways, reducing pro-inflammatory cytokine production including TNF-α and IL-6. The bitter principles also activate taste receptors in the digestive tract, stimulating gastric acid and digestive enzyme secretion.
Clinical Narrative (Provisional)
Most research on Long Dan Cao consists of traditional use studies and in vitro investigations of its bioactive compounds. Animal studies with 50-200mg/kg doses showed hepatoprotective effects against chemical-induced liver damage within 2-4 weeks. Small human observational studies (20-40 participants) reported improved digestive symptoms and liver enzyme markers after 4-8 weeks of use. However, large-scale randomized controlled trials are lacking, limiting evidence strength for specific therapeutic claims.
