Does it really reduce sex drive?
Saltpeter is the colloquial name for mineral potassium nitrate. The source of the word is vague, but seems to refer to “salt stone” because that’s what it looks like.
Potassium nitrate is used in fireworks, dynamite, fertilizer, gunpowder, and other industrial uses.
There is long folklore around the usage of saltpeter to reduce sex drive in men, especially men in confined, sex-deprived situations, like the military or prison. In the US Navy, for example, it is common legend that saltpeter is secretly added to the drinking water in ships.
However, there is no evidence that saltpeter can reduce sex drive, or has ever been used to reduce sex drive. There doesn’t seem to be any scientific basis – either practical or theoretical – that this would achieved the stated effect.
The source of the legend is unclear. One reason might be very adolescent: “saltpeter” sounds similar to “soft peter,” which might be a byproduct of lack of sex drive.
Why I Looked It Up
I had heard this rumor when I was in the Navy. There was also a Beavis and Butthead episode where they accidentally consumed saltpeter and lost all interest in sex.
The term came up in a book about oil exploration. It was discussed in its relation to the manufacture of dynamite, and I was embarrassed that I had never heard of it in this context. I had to look it up.
