Article: Spanish Sage Enhances Memory in Healthy Young Volunteers

 

Sage (Salvia) has a longstanding reputation in British herbal encyclopedias as

an agent that enhances memory, although there is little evidence regarding the

efficacy of sage from systematized trials. New research published in

Pharmacological Biochemical Behavior (June, 2003) confirms that sage is useful

for memory function, at least in the short term.

In a two-trial experiment, researchers Tildesley, Kennedy, et al. (Northumbria

University, Newcastle upon Tyne) set out to determine the efficacy of sage in

improving the memory of young adults.

Two experiments utilized a placebo-controlled, double-blind, balanced, crossover

methodology. In Trial 1, 20 participants received 50, 100 and 150 microl of a

standardized essential oil extract of Salvia lavandulaefolia and placebo. In

Trial 2, 24 participants received 25 and 50 microl of a standardized essential

oil extract of S. lavandulaefolia and placebo.

Assessment was undertaken using the Cognitive Drug Research computerized test

battery prior to treatment and 1, 2.5, 4 and 6 hours thereafter. The primary

outcome measures were immediate and delayed word recall.

A 50-microl dose of salvia essential oil significantly improved immediate word

recall in both studies.
