* Noxious: This word means harmful or poisonous, directly stemming from "nox" and implying an injury to health.
* Noxiousness: This is the state or quality of being noxious.
* Nocive: While less common, this word also means harmful or injurious.
It's important to note that "nox" isn't the most prevalent root for "injury" in English. Instead, words with "inj" are much more common, like injurious, injustice, injure, injury, injudicious, and injunction.
