CONSTITUTION:Leaves of Gymnema are roasted at 100-250 deg.C for 10-40min and then cooled to room temperature Foreign materials, such as stems, are removed to coarsely roll the leaves. The resultant dried Gymnema leaves are blended with green tea leaves, such as roasted green tea, to prepare a health green tea. In the process, the ratio of the blended dried Gymnema is preferably 10-60% based on the totals solid weight. Thereby the tastiness is remarkably improved and the tea can be used for drinking without impairing the essential taste of the green tea.
