10 Things You Didn’t Know About The Spanish Fly

With humans becoming busier as the years go by, this has taken a toll on our lives. We are always under stress and still find ways to deal with it.

One of the aspects of our lives most affected is our sexual health. Our hectic schedules and constant struggle with overcoming stress has lead to a decrease in libido and even made us go as far as to label sex “a routine”.

This true fact is a nagging problem in our society today. And this has lead to an increasing search for different methods — scientific, psychological, medical, and even spiritual in some cases — to boost our libido and revamp our sexual lives, so that we can enjoy maximum sexual pleasure regularly.

Obviously, the search for a solution to this problem is not a new thing, it has been going on since the ancient times.

Our forefathers did their research and developed numerous potions and medicine to enhance their sexual urge and achieve maximum pleasure. Of course, a lot of these “Love Potions” were created from magical spells but a small number of them were based on ancient medical and scientific research to make concoctions of potent aphrodisiacs.

The most special and highly regarded in the group of aphrodisiacs is the spanish fly.

The Spanish fly is one of the oldest and most potent aphrodisiacs. It is known by a lot of people, even in the present day. We’ll be taking a look at the principal source of the active ingredient in the Spanish fly aphrodisiac.

Spanish Fly. Or More Appropriately, Cantharidin.

If you have been left wondering about what the Spanish fly is, here’s some info to help you with that:


  • The Spanish fly aphrodisiac isn’t gotten from flies, as most people would assume. It’s gotten from a green colored insect called the Spanish fly — (“But you said it’s not gotten from a fly?” Relax I’ll explain)


  • The Spanish fly is not a fly, but rather a beetle (Lytta vesicatoria) which belongs to the family of blister beetles.


  • It’s a Southern European insect (you were thinking Spain?) also found in Siberia and some Southern Asian countries.


  • The family of blister beetles are known for producing Cantharidin, which is the active ingredient in the Spanish fly aphrodisiac.


  • The Cantharidin found in the Spanish fly (and other blister beetles) is an aggressive vesicant; that is, a substance that causes the formation of blisters on the skin surface, if brought in contact with the substance.


  • The blisters formed by Cantharidin, although severe, are painless and they usually disappear after a few days.


  • The Spanish fly primarily produces Cantharidin to protect itself from predators. The substance is exuded from its body as a whitish fluid which has a negative effect, on contact with skin.


  • Cantharidin is only produced by the male Spanish fly. The female only receives the substance during mating as a nuptial gift to make the male Spanish fly ‘capable’ and produce viable offspring.


  • Cantharidin, if ingested in large amounts, is highly toxic and usually leads to death in a short time.


  • Cantharidin is also used for removing warts on the skin and also as incense in Siberia (bah! not sure if I wanna smell that).

Due to the highly toxic nature of Cantharidin, it must be handled carefully and kept in a safe place to prevent accidental poisoning.

There are notable cases of effective Cantharidin use (and rather unfortunate happenings) in history, dating back to the early ages.

Personally, I think we shouldn’t be asking “does Spanish fly really work as an aphrodisiac, as people claim?”, but rather “how powerful is Spanish fly?” and “what are the risks of using it the wrong way?”
