來杯kava.kava茶
市麵上聲稱有各種療效的茶種類很多，看多了眼花繚亂有種疲勞感，幹脆那種都不信。平時基本遵守民間頗為流行的喝茶還要喝綠茶的說法，有時換點紅茶喝。前不久一次從文學城博客偶然看到kava茶的說法。以前從末留意過，這次好奇心驅使買回了一盒 Yogi Kava Stress Relief 茶。做了二周個體臨床實驗，有效果。在這裏和網友們分享一下。
Kava 是種產於南太平洋島嶼的植物（Piper methysticum), 拉丁文 'pepper' 希臘文意為 令人陶醉的('intoxicating')。Kava 茶由根部和地下莖磨成粉末製作而成。南太平洋諸島國人民己有上千年飲用kava 茶的曆史，是宗教儀式，各種儀式活動或聚會中不可或缺的。
感謝現代生活帶來的各項便利。不用萬裏超超飛到南洋小島國去，
維基”Kava” 一文中引用了二段頗有詩意的描述：
"A well prepared Kava potion drunk in small quantities produces only pleasant changes in behavior. It is therefore a slightly stimulating drink which helps relieve great fatigue. It relaxes the body after strenuous efforts, clarifies the mind and sharpens the mental faculties"
"When the mixture is not too strong, the subject attains a state of happy unconcern, well-being and contentment, free of physical or psychological excitement...Kava soothes temperaments. The drinker never becomes angry, unpleasant, quarrelsome or noisy, as happens with alcohol. Both natives and whites consider kava as a means of easing moral discomfort. The drinker remains master of his conscience and reason. "
kava 茶有十幾種有效成份，作用機理不完全清楚，但目前己知的基本科學道理如下: 作用並促進大腦神經遞質多巴胺係統(Dopaminergic system) 的活動,另外作用於大腦神經遞質五脛色胺係統(Serotoninergic system). 多巴胺作為神經遞質調控中樞神經係統的多種生理功能。
Kava即是茶又是藥，對精神意識有一定甚至明顯作用，
注意事項：質量和劑量是關鍵。質量上講Yogi 牌子的茶還是讓人比較放心的。劑量上完全可以自己把握, 一袋茶可以自己掌握分2-
