There are two items with "heart" in their name in base game. Dwarven heart (looks like a heart symbol) and orc heart (looks like an anatomically-correct heart).i think the same, but event in the base version, idk which race give "heart" items by dismantling ^^" maybe all slaves, like pheromons ?
It seems like "bodily fluids" is common among all races and diseased DNA comes from any diseased being, while the rest of the ingredients are each specific to one race of slaves or monsters. For example, pheromones are from humans.
