The aim of this study was to evaluate the antivenom properties of Schumanniophyton magnificum; a plant of the Rubiaceae family used in the treatment of snake bites in several rural localities of Cameroon. After harvesting and identification, hydro ethanolic solvent was used for the extraction of the plant by using 2.526 kg of powder of stem bark of the plant. In vitro activity tests were carried out to evaluate the effect of the plant on the activity of phospholipase A2 using egg yolk, and on hemolysis induced by Bitis gabonica venom on red blood cells of rats. In vivo, the effect of Schumanniophyton magnificum on the venom was assessed by evaluating the response on the fever induced by the venom. Hydro ethanolic extracts of the Schumanniophyton magnificum stem bark showed significant inhibition of phospholipase A2 with optimal activity. The plant also inhibited the hemolytic activity of viper venom on red blood cells. Schumanniophyton magnificum decreased the rectal temperature of animals. It appears from the present study that Schumanniophyton magnificum has antivenom properties against the bites of Bitis gabonica viper.
