A Chinese herbal formula has shown potential for improving working memory performance in healthy adults, an Australian pilot study has found. Sailuotong (SLT) is a standardised three-herb formula that combines specific doses of the key bioactive constituents from the concentrated extracts of Panax ginseng (ginsenosides), Ginkgo biloba (flavone-glycosides) and Crocus sativus (crocins), which has been developed to enhance cognitive and cardiovascular function. Using a randomised crossover design, the study assessed the effect of treatment for one week with SLT and placebo on neurocognitive and cardiovascular function in 16 healthy adults. Neuropsychological testing showed that treatment with SLT, but not placebo, resulted in small improvements in working memory.
