包装上没有列举这个“茶”的成分，或包含何种草药。
这东东原产于热带，乃是泊来品，不是传统中统中药。如番茄、番薯一般，为引进物种。
那个名字，起得很好，一看就知道哪来的，干嘛的，用的那部分。

番泻叶是一味中药，其性寒味苦，主治热结便秘。它虽治标但不治本，能解便秘的一时之急，但不能长久服用。如果服用剂量过大可引起肠道炎症性充血和蠕动，使肠道水分急剧下降，肠内干燥少液，反而加重便秘。另外，长期服用番泻叶可产生依赖性，诱发结肠黑变病，甚至肠癌，故坚决不宜长期服用含有番泻叶的药物治疗便秘。

番泻叶不可以减肥，副作用大
1. 首先可以非常明确的告知大家，番泻叶只是一种常用的泻药，并不是减肥药，也没有减肥的功效。如果长期服用番泻叶或者含有番泻叶成分的药物，不仅不会起到减肥的作用，甚至还会形成依耐性，对身体健康造成危害。
2. 部分人群服用番泻叶过量后可出现恶心、呕吐、腹痛。皮肤过敏甚至严重可出现过敏性休克等不良反应；如果长期服用，还会引起肠功能紊乱、便秘加重。 此外经常服用番泻叶会出现药物的依赖性，一旦中断服用，会出现脸部潮红、体温升高、焦虚不安、彻夜难眠、食欲不振及呼吸加快、血压升高、全身疼痛等不适反应。 因此番泻叶具有泻下作用，短时间内貌似是有一定的减肥作用，但是番泻叶的副作用不可小视，最多也就是便秘时偶尔喝上一点，用来缓解便秘。

两位啥都没搞明白，瞎叽个。
真有点为吃兄耽心，自己配药自己熬。不辨证知药，得多自信才敢喝。
