【 かぜ薬・kazegusuri 】cold medicine (also written 風邪薬)
「かぜ」 (kaze) means “wind” and the kanji is written「風」. It is also the word for a cold, but the kanji is written「風邪」. Why? There’s no particular reason. It is 当て字 (ateji), a phonetic equivalent (as with many kanji in Japanese), but there is an etymological reason to why a cold is called かぜ.
