American Ginseng Linked to Improved Memory

Tooth Bonding

Laboratory studies have long pointed to the benefits of American ginseng. The root is thought to have a number of benefits, and a study published in March of 2015 adds one more to the list: improved working memory in middle aged adults.

Study Reports American Ginseng Improves Memory in Adults

52 healthy individuals between the ages of 40 and 60 were selected for the study, in which subjects were required to take 200mg of American ginseng or a placebo daily. Cognitive performance was monitored after one, three and six hours of taking the supplement. Mood and blood sugar were measured, too.

The researchers found improved working memory after three hours in those who took the American ginseng. Spatial working memory was improved, too. Mood and blood sugar were not affected in a significant way.

“These data confirm that P. quinquefolius [American ginseng] can acutely benefit working memory and extend the age range of this effect to middle-aged individuals. These changes are unlikely to be underpinned by modulation of blood glucose in this population,” the researchers said in a statement.
