Please consider augmenting the definition of the word "aperient." In the Loeb Classical Library edition of Aristotle's "Nicomachean Ethics," on page xxiii of the Introduction we find the following footnote: "It is an aperient book, if I may use the phrase. I have never forgotten the effect it produced on me when I was an undergraduate."
In this case the context would suggest "revelatory" as the meaning, not just "laxative," which would seem to be in keeping with the Latin aperient-, present participle of aperire "to open."
Since I am not an expert in this field, I readily defer to the judgment of those who are.
