樟脑丸的味道刺鼻。

The smell of mothballs is very pungent.

我外公的衣服总是有樟脑丸的味道。

My grandfather's clothes always have the smell of mothballs.

问题是，我有一个开放式书柜，我把樟脑丸没有任何效果？

Problem is that I have an open bookcase, I put mothballs have no effect?

现在大家家里都有的樟脑丸就是香樟树根、茎、枝、叶蒸馏而成的。

Now everyone at home is to have a camphor ball camphor roots, stems, branches, leaves made of distillation.
