Soured milk

Soured milk is a cut content potion in .
This potion exists in the game files and can be obtained through console commands, but its purpose and originally intended effects are unknown, as it wasn't fully implemented. There is no formula for creating it present in the game files.
It is likely that it was meant to be used during a quest, but it appears in the regular "Potions" inventory tab. If consumed, it will trigger the same effect as Black Blood (literally pointing to the same effect definition) and has the same status icon in the HUD, though whether it applies to vampires or other types of enemies has not been tested.
