Spanish Fly

Spanish Fly. The green beetle and the world-known aphrodisiac. Wikipedia is teaching us that everybody who is looking for Spanish Fly wants to read about the green beetle. The fact is, nobody cares about the beetle. Spanish Fly is a powerful aphrodisiac. And that is all that matters.

But ok, I will write down some things about the beetle as well. If you want to read it, it’s below the post.

What is the best Spanish Fly?

Yes, there is not only ONE Spanish Fly product. There was. The original one. The dangerous and toxic one. You can’t buy it anymore. And it is for good.

The better news is that there are much stronger and better alternatives. Let’s talk about a few of them.




Today, Helen Scales puts cantharidin – a popular heritage of French cuisine and an active constituent of the much-acclaimed Spanish Fly aphrodisiac – under the microscope so as to uncover its secrets. Read on to find out more.

Have you ever toyed with the idea that frog legs could be a sumptuous treat? If so, then get ready to change your mind. Our tale starts somewhere at a military base in Nigeria in 1869 when resident physician Dr J. Meynier tended to a group of French soldiers plagued by a strange illness characterized by synonymous symptoms. The troop exhibited dry mouths and stomach aches while they all attested to feeling nauseous and weak. Meynier would have had trouble figuring out what the problem was but for the resolute erections they had which led him to believe a certain insect was responsible.

The Spanish Fly was the perpetrator in question with this blend of insect parts renowned as a first-rate aphrodisiac since time immemorial. It might be called so, but it is neither a Fly nor does it hail from Spain rather it is an emerald blister beetle that can be found across the globe. While the French soldiers said they hadn’t come into contact with any Spanish Fly, they did acknowledge sprucing up their diet with frogs they got from a nearby stream. Curiously peaked by the subject, the knowledgeable doctor went to the source where he came across an assembly of frogs that were feasting on vibrant green-colored beetles. He consequently concluded that by eating the frogs, the troop had also, by extension, ingested the toxins from the beetle which was the reason for their current predicament.

Cantharidin is the particular constituent of the Spanish Fly thought to hold its potency and this colorless, odorless solid has been experimented with for thousands of years. In ancient China, this extract from the blister beetle was sought as a remedy for rabies, ulcers and piles while Greek physician Hippocrates recommended the insect as a cure for dropsy countless centuries ago. While it still remains a grey area whether all these are true, what is certain is that Spanish Fly is potent stuff. So the next time a blister beetle talks a walk on your hand, you better pray he is out to play because if not, he’ll leave you an undesirable gift of cantharidin that comes with blisters.

The blister/lesions come about when the aforementioned terpenoid severs cell structure by interfering with transmembrane proteins; a trait that has proved useful in the treatment of molluscum contagiosum and other skin conditions such as warts. That doesn’t mean that you should set out for these beetles as the above was only attained in the eye of the most experienced medical experts.

On the flipside, ingested blister beetles will trigger swelling of the gastrointestinal tract and could even erode the stomach lining in its entirety if the dose is really high. The kidneys, as a result, will go into overdrive to get rid of the accumulation of toxins which manifests in the urinary tract as a swelling wrongly perceived as an erection. Cantharidin is mentioned in the same breath as lethal strychnine and cyanide and the worst bit is that it’s incurable. Long ago, hardboiled French aristocrat Marquis de Sade faced judicial execution for attempted murder when he gave a group of prostitutes Spanish Fly accented chocolates. This goes to show just how dangerous the compound was perceived.

Conversely, beetles use the terpenoid as a love potion. In a bid to get the green light to coitus, the male blister beetle will offer the female a limpid orb of the substance which he secretes via the knees and fashions it into a sphere. The damsel will give it a good sniff and if she approves of it, the male gets his wish. The fire-colored beetles, on the other hand, also adopt a similar approach to mating, however, the male doesn’t secrete the cantharidin himself rather he has to scour the forest canvas to lick it off a dying or dead counterpart. The compound serves other purposes beyond mating as it also doubles up as a protective barrier for newly-hatched eggs that keeps predators at bay.

Aside from beetles and humans, birds have also been known to use cantharidin. Like holy water to vampires, nuthatches rub blister beetles on the entrance of tree holes with their beaks in an effort to ward off squirrels and stay ahead of the intense competition for spaces. It is unconventional but nonetheless commendably ingenious.

Today, Cantharidin is categorized alongside illegal substances by various governments around the world though there are secluded corners of the interwebs where it can be found. Moreover, every once in a while there are isolated cases of poisoning due to accidental contact with the blister beetle itself.

On the market exists new products, which are safe, approved by FDA and have the same effects and resuls as the original Spanish Fly. An important difference is, that the newly developed products like Spanish Fly Pro or Spanish Fly Love are completely without any sides effects!
