Some popular ingredients currently being used in products to promote relaxation or reduce stress include botanicals such as chamomile, passionflower, and valerian.
Most people are familiar with chamomile in tea form as a mild sedative and muscle relaxant and another less well-known botanical, gotu kola, has been known to enhance cognitive function including memory and alertness and reduce mood disorders.
Passionflower is a sedative, and valerian is a muscle relaxant.
