Ce que c\u2019est<\/h2>\n

Le ginseng am\u00e9ricain (Panax quinquefolius<\/em>) est une petite plante vivace des for\u00eats de l\u2019est de l\u2019Am\u00e9rique du Nord, de la famille des araliac\u00e9es. C\u2019est un proche parent du ginseng asiatique (Panax ginseng<\/em>), mais une esp\u00e8ce diff\u00e9rente. On utilise sa racine, cultiv\u00e9e surtout au Canada, aux \u00c9tats-Unis et en Chine. Elle contient des gins\u00e9nosides et des polysaccharides.<\/p>\n

Dans un essai canadien chez 279 adultes<\/a>, un extrait de racine riche en polysaccharides pris pendant 4 mois a r\u00e9duit le nombre moyen de rhumes par rapport au placebo. D\u2019autres essais portent sur la m\u00e9moire de travail et sur la glyc\u00e9mie.<\/p>\n

Une dose de 10 ml de Vita\u00e9lix apporte 80 mg d\u2019extrait sec de racine de ginseng am\u00e9ricain, avec du ginseng asiatique, du ginseng sib\u00e9rien, de la maca, de la rhodiola, de la gel\u00e9e royale, du pollen et de la spiruline.<\/p>\n","protected":false},"excerpt":{"rendered":"
