产生这则故事的原因可能是有些蟾蜍有毒腺，会让人长出看起来像疣的疹子。

A possible source of this myth is that some toads have poison glands that make humans break out in a rash that looks like warts.

可是，如果你说一个生物，会从你的表皮往表皮以下的真皮层“注射”有毒物质的话，那么表达这样的情况所应该用的正确词是“有毒腺的”。

But if you talk about a creature that injects poison through your skin into the soft layers underneath, the correct word is "venomous".
