In q. 8, art. 3, the Common Doctor of the Church S. Thomas Aquinas, proves in De Malo that pride belongs to the irascible appetites. Love and sorrow, on the other hand, belongs to the concupiscible appetites.
“There are two kinds of passions, and they take their general names from the appetites they follow; thus we distinguish the concupiscible passions which follow the concupiscible appetites, and the irascible passions which follow the irascible appetites.” (Tour of the Summa, Paul J. Glenn catholictheology.info/summa-theologica/summa-part2A.php?q=221)
As abovementioned for the most part envy comes from pride. I would disagree that envy is rooted in the concupiscible passion of love. Rather, it has its roots in the irascible, which is a passion involving the overturning of obstacles by fortitude and temperance. The remedy cited from John Chrysostom pertains to battling the irascible. And humility is a virtue under the auspices of temperance.
