Potion Ingredients act Like mini potions.
So when you eat a spider eye it gives you poison 1 for 5 seconds.
I would love if all potion ingredients worked like this. For example sugar would give you 5 seconds of Speed 1, or a Blaze Powder could give you strength 1 for 5 seconds.
Just seems weird that it works for one but not much else.
Additional: to make sure the 5 seconds if actually helpful potion ingredients should have a faster animation for eating, kinda like dried kelp.
(Phantom membranes would be pretty helpful in terms of falling and saving yourself)
