The New Craze in English Soccer: Horse Placenta!

The skeptical movement in America has grown substantially in the last few years. I shouldn’t even say that it’s grown but rather that it’s exploded onto the scene. Europe, on the other hand, is having a slow start.


Last fall, news broke in the English Premiere [Soccer] League (EPL) of a radical new treatment involving several high-profile players. At least 12 players had seen an alternative medicine proponent, Marianna Kovacevic, to undergo a procedure to cure a variety of injuries in her homeland of Serbia by using a special gel created from horse placenta. That’s right… repeat after me… HORSE PLACENTA!

Before going into the technicalities, it should be noted that this was a complete media fail. Coverage was hardly skeptical and I was especially disappointed by the UK’s reporting on this matter since so many of their citizens are die-hard fans of the teams these players are on, as well as the players themselves.

Robin van Persie, for example, was named Barclay’s Premiere League Player of the Month last October and plays for Arsenal Football Club, the third richest soccer club in the world. One would think that with so much money on the line, all reliant on the performance  of a few players, the care and advice given to these players would be the best in the world. Think again.

It’s no secret that EPL soccer players can seek unusual treatments to cure their rather typical sports-related injuries. Wayne Rooney, currently the top goal scorer, used a hyperbaric oxygen (HBO) chamber to heal a fractured metatarsal in 2006. This alternative modality of treatment is not established to be effective by the scientific community. Such alternatives are not only supported by the players themselves, but also by the teams they work for.


Rumor has it that Manchester City Football Club had contemplated hiring Kovacevic to formally treat their own players. Rafael Benitez, manager of Liverpool Football Club, also fell for the act hook line and sinker. He sent 6 of his own players to Serbia for the controversial treatment. Is this why his top-four team has dropped in ranking so much this year? Ouch! Obviously not, but such management of his players’ health causes me to question his common sense.

Marianna Kovacevic claims that her horse placenta treatment speeds up the recovery of injuries by using stem cells present inside of it to increase the healing process. This sort of scam is not new. Quacks like Dr. Huang from China have been selling bogus stem cell treatments for years. Stem cells are a very sexy topic in medicine because of the immense potential they have for curing disease. The key word there being potential, as there are yet very few applications for stem cells in medicine and absolutely none in the sports medicine department.

How does Kovacevic use these stem cells to cure torn ligaments and broken bones, you might ask? Don’t expect to get an answer. Kovacevic has clouded her methods in mystery and refuses to explain her technique. This sort of ambiguity is a red flag and is common in the alternative medicine world. That’s OK, because Liverpool’s own Yossi Benayoun leaked a vague description of the treatment and explained that,

“Nothing went into the muscle itself. It was just a case of massaging the liquid on to the skin around the affected area.”

Well that’s a relief. At least she isn’t injecting foreign material into the tissue. This could lead to infection and more inflammation as the body’s natural response to foreign material is to attack it with an immune reaction. So how could stem cells on the surface of the skin affect the damaged tissue deep beneath? They can’t!

Assuming somehow the cells could travel across the skin and subcutaneous tissues to reach the ligaments or bones, which if they could would mean we would have a constant bombardment of microbial pathogens seeping into our blood, there still is no explanation for how these cells would help us heal. For one, horse placenta is completely foreign to our bodies. Cells from another species contain too many ‘unusual’ markers on their surfaces to be accepted by our immune systems.

Even if they weren’t destroyed immediately by the host’s immune cells, the stem cells wouldn’t just start multiplying and transforming into whatever tissue surrounds them. That would require a special environment and exact cell signaling molecules, one of the many hurdles for stem cell researchers.

Dusan Petrovic, a Serbian player and former patient of Kovacevic, explained that her treatment involved,

“a combination of electricity and the miracle gel that is her exclusive product. The electric current goes through a stick holding the gel, which is applied to the injured spot.”

Kovacevic adds electricity to the lure! If electricity could heal sports injuries, wouldn’t every famous player be attached to an electric current after breaking a leg or spraining an ankle? This additional electricity only adds to the placebo effect that these players are experiencing because it is a well known fact that the more invasive and technical a treatment seems, the more inclined the patient is to feeling an improvement in their symptoms.

If anything, I propose that traveling to rural Serbia for a factitious cure by a non-professional would only aggravate a sports injury. Musculoskeletal injuries are meant to be stabilized to let the body use it’s well known and documented ability of healing itself without any disruptions. Otherwise, there will be more inflammation, which is supposed to be suppressed as much as possible to prevent the build up of scar tissue. Ice also helps prevent inflammation. Not electricity with animal placenta and amniotic fluids. For me, it’s repulsive to even think about.

But why is this placenta treatment so popular amongst these extremely valuable players? The answer lies in the susceptibility of our minds to unconsciously cherry pick positive results. For the same reason that people think vitamin C cures a cold, soccer players believe that placenta treatment could cure breaks and tears. Anecdotal evidence runs rampant in all societies. Misinformation spreads because people claim efficacy for treatments without considering their own bodies’ abilities to heal. A placebo effect leads to a belief that a false treatment works, which is then propagated through anecdotal evidence to other people, and they too start to believe in the nonsense.

I haven’t read much about Kovacevic recently. Last I heard, she has gone into hiding from allegations by the Serbian Health Commission of fraud and illegally treating patients without a license along with tax evasion for charging different amounts depending on the profile of the player. This will only add to her martyrdom for her believers. To them, she is another guardian of alternative healing from the evil conspirators of modern western medicine.

This whole story in general is not surprising to me at all. Like I said, it’s not uncommon for high profile players to search for miraculous cures to speed their recoveries. The thing that struck me the most, however, was the complete lack of skepticism to all of this. Effectively, the incompetent UK media reported of a Serbian housewife electrically shocking horse placenta fluid onto some of it’s most cherished athletes without mentioning a hint of wrong doing. Dropping the word ‘controversial’ into a long article does not suffice to create a balanced story.

Even now there are only a few skeptical posts about this on the internet, after a whole media-storm of coverage last fall. I think that the lack of skepticism on this subject should be brought to notice by the public at large so that reporters can do a better job of doing their homework when covering such stories in the future. Also, the medical staff of sports teams and doctors in general should be more outspoken about such pseudoscientific treatments and should not allow their patients to undergo these sorts of bogus therapies. This is especially true in Europe, where I personally believe skepticism is not abundant enough.

And come on! Horse placenta for sports injuries? Seriously???? Some people need more common sense!

    While the idea that horse placentas cure sports injuries does seem very silly to me, I’m not as skeptical as you are. Working at IAHP, I have heard some call all of our methods “pseudoscientific”, although neuroplasticity is now a pretty well established phenomena. I’m not saying we should all go running for horse placentas when we sprain our ankles, but I think its important that the scientific community keeps its mind open to new ideas. Once an “establishment” is created, it usually starts to stop listening to new ideas, and that is very dangerous.

    I really enjoy your writings. keep it up!

    Very interesting topic you chose there. Regarding scepticism in Europe and especially the UK latley. There is some interesting things going on there.
    First of since over a year there is the case of Simon Singh vs BCA.

    Also prominent was the 10^23 campaign.

    The only criticism i would have is that you should use more links linking to the original story and evtl. other sources. Besides of that i hope you will keep up regular posting^^

    Regarding scepticism in europe. There have been a few things going on in the UK.

    1st since a year or two there is the case Simon Singh vs BCA

    And just recently the 10^23 campaign and the evaluation of Homeopathy by a palimentary comitee.

    Besides of that i just have one minor criticism. It would be helpful if you included mor links linking to the original stories and other sources. Keep on posting^^

    P.S.: interesting link regardin Homeopathy:

    I have had horses treated with horse placenta and the cells did exactly what your article says they will not do. They adapted to the area they were attached to and formed a hard surface to protect a hole in my horses hoof wall. Instead of being laid off 6 -8 months for the hoof to grow out he was back in the show ring in three weeks. There are amazing uses for it and I would not hesitate to use it.
