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

L\u2019euphraise (Euphrasia officinalis<\/em>) est une petite plante annuelle des prairies et des p\u00e2turages de montagne, de la famille des Orobanchac\u00e9es. Elle est semi-parasite : ses racines se branchent sur celles des gramin\u00e9es voisines pour y puiser une partie de leur eau et de leurs sels min\u00e9raux. On en r\u00e9colte les parties fleuries. Son nom anglais, eyebright, rappelle son usage traditionnel pour les yeux.<\/p>\n

Cet usage passe surtout par le collyre. Dans une \u00e9tude men\u00e9e en Allemagne et en Suisse chez 65 patients atteints de conjonctivite<\/a>, un collyre d\u2019euphraise a \u00e9t\u00e9 suivi d\u2019une gu\u00e9rison compl\u00e8te chez 53 d\u2019entre eux et d\u2019une nette am\u00e9lioration chez 11. En laboratoire<\/a>, des extraits d\u2019euphraise ont r\u00e9duit la production de mol\u00e9cules de l\u2019inflammation par des cellules de corn\u00e9e humaine.<\/p>\n

Une dose de 10 ml d\u2019Optirenov apporte 300 mg d\u2019extrait sec d\u2019euphraise, avec du terminalia, de la myrtille, du ginkgo, du DHA d\u2019algue, de la lut\u00e9ine, de la z\u00e9axanthine, de la querc\u00e9tine, du zinc et des vitamines A, B2 et C.<\/p>\n","protected":false},"excerpt":{"rendered":"
