Studies
• Antibacterial / Anti-Urolithiasis: Study of 17 plant species screened for potential antibacterial activity against four selected urolithiasis-inducing flora (P mirabili E coli, Pseudomonas stutzeri and K pneumonia) showed six plants, including C. adnata to show promising roles in the prevention and cure of urolithiasis.
• Free Radical Scavenging Activity: Study yielded a triterpenoid, flavonoid and apigenin. Study comparing isolated compounds of C. adnata and Smilax lanceaefolia showed the compounds to have moderate to high free radical scavenging activities
