The inventory system how it currently is, is horrible.
The game incentivizes you to pick up ingredients, but you al basically always full.
Might be a better system to have like an internal storage for all ingredients, similar to how Diablo 4 does that currently. Just basically a “list” of all the stuff, and how much you have. You can even put a max cap on it.
Leave the inventory for just “normal” items you find, if that is implemented it should already feel a LOT better.
