A plant offering countless health benefits, sage is an herb as old as time. And while it’s commonly used in cooking, the herb has been heavily utilized in medicine and even spirituality as well. Some of the more recent studies on sage indicate that the herb can improve memory and even possibly prevent Alzheimer’s disease.The study, published in the June 2003 Pharmacology Biochemistry and Behavior, looked at the effects of sage on memory recall tests. The researchers used 45 individuals in two groups; one group received a placebo while others received sage essential oil at dosages between 50 and 150 microls. Following the administration, memory tests were given. Even those who were given the smallest amount of sage oil saw notable memory improvements.
