Kurama does not respond, figuring that anything he has to say on the subject at this point will be read as a lecture. He didn't think that Hiei would risk making himself ill again with Yukina in the room, but clearly he has been proven wrong on that front or they wouldn't be in this current situation to begin with.

The redhead returns shortly with a hot cup of tea, watching Hiei pace for a moment before clearing his throat to announce himself once more. “This should help settle your stomach and let you sleep, though it… may benefit you to come inside to drink it.”

There's no sense in lying about just what the mix did, if Hiei does not want something to help him sleep after all, he was welcome to say as much. It wouldn't be the first time he's changed his mind about what he wanted, and at this stage the fox is not inclined to assume.

He hesitates before speaking up again cautiously, as if not expecting the rest to go over well. “Can I do anything else for you?”
