Previous studies have investigated the effects of an extract of ginkgo biloba on acquisition, performance and retention in rats. It has been suggested that ginkgo increases mental precision by increasing blood flow to the brain. To determine whether ginkgo is a memory enhancer two female Sprague Dawley rats were tested for maze performance during four stages. Stages included four days of maze performance and four days of no maze performance. Subjects were tested in each stage with or without ginkgo in their water supply. It was predicted that subjects would show improved maze performance as measured by a decrease in the number of wrong turns in reaching the goal box when ginkgo was mixed with their water supply. A one-way ANOVA was used to calculate the total number of wrong turns for all four stages. Results of the analysis were not statistically significant. The present data were not consistent with results of previous studies with rats. Continued research is encouraged to investigate the external validity of those studies that proved ginkgo's effects to be beneficial to enhancing memory.
