感冒药在英语中叫做 "cold medicine"。

来源："cold" 是指 "感冒"，"medicine" 是指 "药物"，所以将这两个词组合起来就是 "感冒药"。

例句：

I have a headache and a sore throat. I think I need to take some cold medicine.

我头痛和嗓子疼。我想我需要服用一些感冒药。

Do you have any cold medicine I can take?

你有什么感冒药我可以服用吗？

I always keep some cold medicine in my medicine cabinet just in case I get a cold.

我总是把一些感冒药放在药柜里，以防我感冒。
