• Ginseng

"This is THE plant for stress adaptation," says Dr. Eric Lorrain, President of the European Plant Ingredients Institute (IESV). It has a proven calming action that helps to cope with pressure. Its root is full of ginsenosides, compounds that improve communication between brain cells. They thus boost intellectual performance (concentration, memory ...) which makes it easier to overcome periods of tension.

Studies have shown that griffonia for 15 days reduces mental agitation, anxiety, fatigue and insomnia due to overwork.
