saltpeter
Potassium nitrate mineral
Saltpeter is potassium nitrate, a crystalline compound used historically in gunpowder, fertilizers, and food preservation.
The word comes from Latin for "salt of rock," describing the white mineral deposits found on cave walls and in certain soils.
Folk belief long held that saltpeter suppresses sexual desire, leading to rumors of its use in military and institutional food—a myth with no scientific basis.
