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

La pr\u00eale des champs (Equisetum arvense<\/em>) est une plante vivace sans fleurs ni graines, cousine des foug\u00e8res, qui pousse dans les lieux humides d\u2019Europe. Au printemps sortent des tiges fertiles brunes, puis des tiges vertes ramifi\u00e9es : ce sont ces parties a\u00e9riennes qu\u2019on r\u00e9colte. Elles sont riches en silice, et un litre de tisane de pr\u00eale a fait monter nettement le silicium dans le sang de volontaires<\/a>.<\/p>\n

L\u2019Agence europ\u00e9enne des m\u00e9dicaments<\/a> reconna\u00eet l\u2019usage traditionnel des parties a\u00e9riennes, chez l\u2019adulte et l\u2019adolescent de plus de 12 ans, pour augmenter le volume d\u2019urine et rincer les voies urinaires en cas de troubles urinaires mineurs, et pour les plaies superficielles. Chez 36 hommes en bonne sant\u00e9, 900 mg d\u2019extrait sec par jour ont eu un effet diur\u00e9tique comparable \u00e0 celui d\u2019un m\u00e9dicament diur\u00e9tique, l\u2019hydrochlorothiazide<\/a>.<\/p>\n

Arthrylax apporte 1 200 mg d\u2019extrait sec de pr\u00eale par dose de 20 ml, avec de l\u2019harpagophytum, du cassis, du bambou, de la glucosamine et de la chondro\u00eftine.<\/p>\n","protected":false},"excerpt":{"rendered":"
