The chemical that both wins wars and, legend says, kills your libido in them.

means A naturally occurring salt (potassium nitrate) used to make gunpowder, cure meat, and preserve food.

from From medieval Latin 'sal petrae' — literally 'salt of rock' or 'salt of stone' — because the crystals were found crusting on rocks, cave walls, and old masonry (often where nitrogen-rich organic waste had seeped into stone or soil). It traveled into English via French 'salpêtre' and kept that two-part shape: salt + stone.
