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

Le ginkgo (Ginkgo biloba<\/em>), ou arbre aux quarante \u00e9cus, est un arbre originaire de Chine, seul repr\u00e9sentant encore vivant d\u2019une famille apparue il y a plus de 200 millions d\u2019ann\u00e9es. On utilise ses feuilles en \u00e9ventail, qui contiennent des flavono\u00efdes et des terp\u00e8nes propres au ginkgo, les ginkgolides et le bilobalide.<\/p>\n

L\u2019Agence europ\u00e9enne des m\u00e9dicaments<\/a> reconna\u00eet un usage bien \u00e9tabli d\u2019un extrait sec purifi\u00e9 de feuille, \u00e0 240 mg par jour, pour am\u00e9liorer les troubles cognitifs li\u00e9s \u00e0 l\u2019\u00e2ge et la qualit\u00e9 de vie en cas de d\u00e9mence l\u00e9g\u00e8re, et un usage traditionnel de la feuille en poudre pour soulager les jambes lourdes et la sensation de mains et de pieds froids li\u00e9es \u00e0 de petits troubles circulatoires, une fois qu\u2019un m\u00e9decin a \u00e9cart\u00e9 une maladie s\u00e9rieuse. Chez les personnes atteintes de d\u00e9mence, une synth\u00e8se Cochrane<\/a> trouve des b\u00e9n\u00e9fices \u00e0 six mois sur la cognition et les gestes du quotidien.<\/p>\n

Une dose journali\u00e8re de 10 ml d\u2019Optirenov apporte 63 mg d\u2019extrait sec de feuille de ginkgo, avec de l\u2019euphraise, de la myrtille, du terminalia, de la lut\u00e9ine, de la z\u00e9axanthine, du DHA et de la querc\u00e9tine.<\/p>\n","protected":false},"excerpt":{"rendered":"
