Treated like cattle potion recipe not working?

[Gitfenion]

Hello,
so I just recently got this game and now i stumbled upon a problem. I met the two cows and found the potion and the book. I was able to read the book and get the recipe but when i try to combine the three ingredients it doesn`t work. Does anyone have some tips?

My only guess is that you aren't using specifically the witch eyes to make it. Those are the ONLY eyes that work.

If I have to use the witch eyes from the hut that are on the table than I should hve the right one?

Should be, yes. You're mixing all three ingredients at once right? You should be able to just do it in your inventory, I dont think you need to make it at a stove or anything
