Well I haven't found a mod that makes the potion brewable at an alchemy table. But took a similar interested and looked for enchantments that might do the same. Here's what I came up with.
playerenchantobject (ObjectID) (Spectral Effect) (Howl of Fear)
playerenchantobject 000877B1 00103647 000CF797
000CF796 : Werewolf Fear Howl 1 (HowlWerewolfFearEffect1)
000CF797 : Werewolf Fear Howl 2 (HowlWerewolfFearEffect2)
000CF798 : Werewolf Fear Howl 3 (HowlWerewolfFearEffect3)
The object itself can be anything you wear in the game, or any ring for that matter. I went for a Silver Ruby one myself. But I admit to being a little stuck about spells that make people flee in terror when they simply see you. The Werewolf effect is the best I could find that isn't spit out as invalid in the console.
I'm open if anyone knows an enchantment ID for people going hostile and running level confidence.
