Professor Ellis says tea has a sanative effect – making you feel better – so I might try munching a few leaves later on.

艾利斯教授说茶叶有益健康，让你感觉更好，那我晚点要试着嚼一些茶叶。

On you and that effect could be thought of as medicinal or it could be thought of as just kind of sanative – making you feel a bit better than you used to feel.

这种作用可能是一种药用作用，或者就是简单的有益健康，总之就是让你感觉比以前更好。
