Abstract
Objective:
This 12-week open-label study evaluated a multi-herbal tablet containing Reynoutria japonica, Vitis vinifera, Silybum marianum, Ginkgo biloba, and Panax ginseng, for potential improvement of cognitive function in 25 healthy older adults (50–75 years).
Methods:
The primary outcome, cognition, was assessed using the Cambridge Neuropsychological Test Automated Battery.
Results:
Significant improvement in working memory was observed. Errors in the Paired Associate Learning (PAL) task and spatial working memory reduced by −7.9 (95%CI: −12.3, −3.5) and −3.3 (95%CI: −6.3, −0.3) respectively, while PAL memory score increased by 2.0 (95%CI: 0.9, 3.1).
Conclusion:
These preliminary results suggest memory improvement, but further rigorous testing is needed.
