I'd recommend AutoLoot Herbs. I generally prefer to avoid mods when playing through a game for the first time, but that was a "quality of life" improvement I couldn't bear to be without. Manually confirming herb pickups got very old very quickly.
Edit: IIRC, the mod displays its own, unnecessary notification upon looting something, but you can disable it by opening AutoLootBase.ws in Wordpad and changing the values of NotificationShouldDisplay to false (if set to true).
