Spanish Fly: Does It Work As Male Enhancement?
For centuries, people have turned to aphrodisiacs in an attempt to boost their sex drive and enhance their sex appeal. Our ancestors ate oysters or chewed special plants — some found even weirder things they believed would give them a bedroom boost.
Spanish fly is one such aphrodisiac. Made famous by Bill Cosby in a (now obviously super controversial) stand-up routine from the 1960s, Spanish fly refers to all sorts of tonics, potions and other “love supplements” made from one type of insect: blister beetles.
Spanish’s fly’s reputation isn’t the best — and not just because beetles aren’t actually flies. This buggy “treatment” is linked to a long list of potential side effects, some of which can be deadly. Meanwhile, there’s only limited scientific evidence that it has much of an effect on sexual performance.
Despite this, Spanish fly is still somewhat infamous several decades later — though most people know little about it. We assume that’s why you’re here.
Below, we’ll explain:
What Spanish fly is
The risks of using Spanish fly and its potential sexual effects
Whether Spanish fly is worth using or should be avoided
Finally, we’ll share a few alternatives you may want to consider if you’re aiming to boost your sexual desire and performance.
What Is Spanish Fly?
Spanish fly technically refers to two things: a type of green blister beetle (Lytta vesicatoria from the family Meloidae) and a toxic blistering agent the beetles produce called cantharidin.
Historically, the green blister beetle was used to treat warts and a skin condition called molluscum.
Cantharidin — the product isolated from these beetles for medicinal formulation — has long been used as a natural aphrodisiac. Several millennia ago, it was used by ancient Egyptians and Romans as a stimulant for orgies, improving sexual relationships and as a tool for committing sexual blackmail.
If sexual blackmail is what you’re here for and you’re wondering where to buy Spanish fly today, hold up a second. First, that’s wrong, and second, you’re in for a disappointment.
In modern times, supplements marketed as “Spanish fly” may not even contain cantharidin. Instead, they might contain various herbal ingredients that — manufacturers claim — are capable of boosting sexual performance, stamina and attractiveness.
Does Spanish Fly Work?
When it comes to non-prescription aphrodisiacs and male enhancement pills, manufacturers are often big on promises but small on actual results. The evidence that Spanish fly works is, likewise, very slim and disappointing.
Purportedly its core ingredient, cantharidin, increases blood flow to the urogenital tract. But the fact is that most reliable research quickly dismisses cantharidin as dangerous for human consumption.
Put simply, authentic Spanish fly isn’t something you or your partner want to consume, no matter what potential you’ve read about. It’s a hazardous substance and cases of poisoning can happen in rare circumstances — which could have serious consequences.

Risks and Side Effects of Spanish Fly
When it comes to products containing cantharidin (and not some other random ingredients), there are serious safety risks you should be aware of if you’re considering taking these types of herbal supplements.
The first very real risk, it turns out, is a little thing called dying.
Cantharidin is listed in the Hazardous Substances Data Bank of the National Library of Medicine.
People have died from using products containing cantharidin. In England, two women were killed by a man who gave them coconut ice laced with cantharidin, hoping it would lead to them having sex with him.
And people in the United States have been rushed to the emergency room after taking cantharidin in the hope of stimulating sexual activity.
Assuming you don’t die, side effects associated with cantharidin you might experience include:
Blistering. Cantharidin is known to cause skin blisters. You may notice skin blisters, a burning sensation, itching and changes in pigmentation after you use products containing cantharidin.
Blood in saliva, vomit or urine. Cantharidin is known to cause hematemesis (vomiting of blood) and gross hematuria (blood visible in urine). It can also cause dysuria (pain while urinating).
Priapism. Cantharidin can cause priapism — a type of painful, long-lasting erection that can damage your penis when left untreated. Priapism is a serious medical emergency that requires urgent attention from a healthcare provider.
Cantharidin poisoning can also cause:
Seizures
Burning of the mouth
Renal dysfunction
Cardiac abnormalities
Nausea and dysphagia (difficulty swallowing)
There’s one final risk of Spanish fly to consider: the mystery ingredient trap. Products labeled “Spanish fly” aren’t regulated by the FDA (U.S. Food and Drug Administration) in the same way that prescription medications are, so there’s no real way to know what’s in them. The FDA maintains a long list of other sexual performance booster supplements that have been found to contain unlabeled, potentially dangerous ingredients.
In other words, you can’t always be sure you’re getting the right amount of cantharidin — or what else you’re getting along with it — from non-prescription sexual enhancement products. And regardless of whether you get any cantharidin, you could potentially die.

Better Options for Boosting Sexual Performance
Spanish fly — any fly of any nationality, really — probably isn’t where you want to look for ED help.
Natural cures are great — in theory. But if we’re being honest, most aren’t practical because we don’t know all of the facts or understand safe and effective dosages.
If we were to tell you cat poop is a natural ED (erectile dysfunction) treatment but that it wasn’t clear how much of it you needed to consume, we hope that information would lead you to visit a doctor — not a pet store.
While Spanish fly is proven to be neither safe nor effective as an aphrodisiac, there are real options available for treating sexual dysfunction and improving your performance in bed.
Some of these require a prescription, while others are available online and over the counter, including:
ED medications
PE medications
Lifestyle changes
Let’s look at each group in more detail.
Erectile Dysfunction (ED) Medications
If you're thinking about using Spanish fly for ED, we get where you’re coming from, even if your plan is bad.
After all, erectile dysfunction is pretty common — it’s estimated to affect approximately 30 million men in the U.S. alone.
But there are safer, scientifically proven options to consider. Currently, the FDA has approved four pills for treating erectile dysfunction:
Sildenafil (the active ingredient in Viagra®)
Vardenafil (Levitra®)
Avanafil (Stendra®)
These all belong to a class of medications referred to as PDE5 inhibitors. They work by increasing blood flow to your penis, making it easier to get and maintain an erection when you feel sexually aroused.
The FDA has also approved an injectable medication, alprostadil, for ED, and it has authorized a topical gel for ED.
We offer several oral ED medications online, following a consultation with a healthcare provider who’ll determine if a prescription is appropriate.
Premature Ejaculation (PE) Medications
Like ED, premature ejaculation (PE) is a common sexual performance issue that can cause serious harm to your confidence and sexual pleasure.
Premature ejaculation is very treatable. If you’re prone to PE, you’ll get the best results by using medication to slow down orgasm and ejaculation. Your options include:
Antidepressants. Some antidepressants, including sertraline (Zoloft®) and paroxetine (Paxil®) are used off-label to treat PE. Research shows that these medications help slow down ejaculation and improve stamina for men with PE.
ED medications. Off-label usage of ED medications, such as sildenafil (Viagra®) can also be effective for PE.
Topical PE products. It’s also possible to treat premature ejaculation topically. Products like our Delay Spray for Men are designed to reduce sensitivity, allowing you to have sex for longer before reaching orgasm.
Lifestyle Changes for Better Sexual Function
While medication may provide the fastest effects, you’ll get the best results by combining it with a healthy lifestyle.
Try the following habits and lifestyle changes to improve your physical health and sexual function:
Stay physically active. Regular exercise can have a hugely positive impact on your physical health, sexual performance and erectile function. Try to get 150 minutes or more of moderate-intensity aerobic exercise per week, as well as a couple of strength workouts per week.
Maintain a healthy body weight. Research has found that having overweight or obesity is linked to a higher risk of experiencing ED. Try to maintain a BMI either within or as close to the healthy range as possible.
If you smoke, try to quit. Research shows that smoking is linked to an increased risk of developing sexual performance issues, including ED. It’s also a key risk factor for other medical conditions, including potentially fatal ones, such as cancer and heart disease. If you smoke, try your hardest to quit.
Live a healthy, balanced lifestyle. From sleep to diet, a variety of factors can affect your sexual performance. Our guide to naturally protecting your erections shares tactics you can use to live a life that prioritizes your sexual health and function.

Why Spanish Fly Pills Aren’t Worth It
Spanish fly isn’t just ineffective as an aphrodisiac — it’s also dangerous. We’ve said it a dozen times already, but we’ll keep saying it! Why? Because dying is bad.
So keep Spanish fly and other herbal aphrodisiacs at arm’s length. There’s just way too much at stake.
Here’s our take on Spanish fly:
By using it to increase your sex drive, you’re putting your health at risk.
Don’t give it to other people in an effort to make them feel more attracted to you.
Giving it to someone else without their permission is both unsafe and illegal.
Why would you do that?
Don’t be that guy.
If you need help with your sexual performance, you can view our range of ED treatments online and connect with a licensed healthcare provider to discuss your needs.
And here’s one final piece of free advice: instead of setting the mood with a European beetle roofie, do it by enjoying a romantic dinner or a glass of wine with your partner — not only is it more effective, but it’s also better for your health and theirs.
