A plethora of medicinal plants have been shown to improve memory, cognition, and intelligence. Zingiber officinale (Ginger) and Cannabis sativa (Marijuana) have been shown to affect memory, cognition, and intelligence too. This study aimed at comparing the effects of Zingiber officinale and Cannabis sativa on learning and memory was carried out in Swiss mice. The mice were randomly divided into 3 groups of 15 animals each. Group 1 (control) were fed mice feed. Group 2 (ginger group) were fed with a ginger-laced diet containing ginger and mice feed at a percentage ratio of 5:95. Group 3 (marijuana group) were fed with a marijuana-laced diet containing marijuana and mice feed at the percentage ratio of 5:95. All mice were fed for 14 days and given water to drink daily. Daily food and water intake were recorded. The mice were evaluated for learning and spatial memory using novel object recognition tests and data obtained were subjected to ANOVA and T test respectively. The result showed that the Zingiber officinale group showed significantly better memory as seen by an increase in the recognition index when compared to the other groups. This shows that Zingiber officinale shows positive effects on cognition than Cannabis sativa at the same dose.
