Conclusão

            
            
Valerian root may help with falling asleep, but the evidence specific to sleep onset difficulty is limited by very small studies.

            
            
            
    
                
                
  • 
                    
                    Only 5 studies with 15 total participants — very small evidence base for this specific use
                
    • 
                
                
  • 
                    
                    60% of studies show positive effects on falling asleep

                    Includes 1 meta-analysis and 1 RCT, but sample sizes are very small

  • 
                    
                    Stronger evidence exists for valerian's general insomnia benefits
