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

Le th\u00e9 vert vient des feuilles du th\u00e9ier (Camellia sinensis<\/em>), un arbuste originaire de Chine et d\u2019Inde. \u00c0 la diff\u00e9rence du th\u00e9 noir, il est s\u00e9ch\u00e9 sans fermentation, ce qui emp\u00eache l\u2019oxydation de ses polyph\u00e9nols ; la plupart sont des cat\u00e9chines, dont l\u2019EGCG (\u00e9pigallocat\u00e9chine gallate)<\/a>. Il contient aussi de la caf\u00e9ine.<\/p>\n

L\u2019Agence europ\u00e9enne des m\u00e9dicaments<\/a> reconna\u00eet l\u2019usage traditionnel de la feuille de th\u00e9 vert pour soulager la fatigue et la sensation de faiblesse. Une m\u00e9ta-analyse de 14 essais randomis\u00e9s<\/a> a trouv\u00e9 une baisse du cholest\u00e9rol total et du LDL chez des adultes qui buvaient du th\u00e9 vert ou prenaient un extrait.<\/p>\n
