Ashwagandha also known as Withania somnifera or Winter Cherry is considered a very useful herb in promoting mental calm and relief from mental and physical exhaustion. Ashwagandha is also said to help improve memory functions in the brain.New research published in the Jan 2014 edition of the Pharmacognosy Research journal indicates that Ashwagandha may also be helpful in improving cognitive and psychomotor abilities. A double blind, placebo controlled study was conducted on 20 healthy adult males. They were given 2 capsules twice daily of 250mg of Ashwagandha root and leaves extract for 14 days. There were marked improvements in reaction times in tests of simple reaction, choice discrimination, digit symbol substitution, digit vigilance, and card sorting tests.
The results showed that cognitive and psychomotor capabilities were definitely improved and this proves promising for further research in treating impaired cognition. More information on Ashwagandha
