The Cordyceps Fungus Behind the Games and Shows: What Is It Really?

In recent years, the mysterious Cordyceps fungus has gained mainstream attention, thanks in part to the wildly popular video game The Last of Us and its acclaimed HBO TV adaptation. In these fictional worlds, Cordyceps mutates to infect humans, turning them into zombie-like creatures in a chilling post-apocalyptic setting.

But is there any truth behind the fiction? Could a fungus really control the human brain? And beyond its dramatic portrayal in entertainment, what role does Cordyceps play in science, medicine, and nature?

Let’s dive into the real story behind Cordyceps, its fascinating biology, potential health benefits, and how it inspired one of the most compelling apocalyptic narratives in modern pop culture.

🧬 What Is Cordyceps?

Cordyceps is a genus of parasitic fungi that includes over 600 species. The most well-known species include:

• Cordyceps sinensis – Traditionally found in the Tibetan Plateau, parasitizing caterpillars.
• Cordyceps militaris – Often cultivated commercially for medicinal use.

What makes Cordyceps unique is its ability to infect insects and arthropods, using them as hosts to complete its reproductive cycle. Once infected, the fungus consumes the host from the inside, then sprouts a fruiting body — often emerging from the insect's head or body — to release spores and infect others.

This gruesome yet fascinating biological strategy has led to Cordyceps being nicknamed the "zombie fungus."

🧟 Cordyceps in The Last of Us: Science Meets Imagination

In The Last of Us, the Cordyceps fungus evolves to infect humans due to climate change. Once infected, individuals lose autonomy and become violent, aggressive “infected”, driven by the fungus to spread itself.

The show’s creators based the idea on Ophiocordyceps unilateralis, a real fungus that targets carpenter ants. In the wild, this fungus manipulates an ant’s central nervous system, forcing it to climb vegetation before killing it — placing the ant in the perfect spot for the fungus to release spores.

While the concept is exaggerated for fiction, it’s rooted in actual biology, making it one of the most realistically terrifying fictional pathogens ever depicted.

Could this happen to humans?
Not likely — at least not now. Cordyceps species are highly specific to their hosts. The real fungus cannot survive in or manipulate human hosts. However, the mutation scenario imagined in the game is a chilling “what if?” that sparks genuine scientific curiosity.

🌿 Traditional and Modern Uses of Cordyceps

While fictional Cordyceps is the stuff of nightmares, the real fungus is considered valuable in traditional medicine, particularly in Traditional Chinese Medicine (TCM) and Tibetan medicine, where it has been used for centuries.

Medicinal Benefits of Cordyceps (Backed by Research):

1. Improved Energy and Stamina
   Cordyceps is believed to enhance the production of ATP, the primary molecule responsible for energy in our cells. This is why it’s often used as a natural supplement for athletes.
2. Anti-inflammatory and Antioxidant Properties
   Cordycepin, a compound found in Cordyceps, has shown potential in reducing inflammation and acting as a natural antioxidant.
3. Immune System Support
   Cordyceps may stimulate immune cell activity, helping the body better resist infections.
4. Blood Sugar Regulation
   Some studies suggest Cordyceps helps in managing blood glucose levels, potentially benefiting people with type 2 diabetes.
5. Anti-aging Effects
   Thanks to its antioxidant compounds, Cordyceps may reduce oxidative stress, one of the key contributors to aging.

🍄 Cordyceps Militaris vs. Cordyceps Sinensis

In today’s supplement market, most Cordyceps products use Cordyceps militaris, which is easier to grow and has been shown to contain higher levels of cordycepin. On the other hand, Cordyceps sinensis, traditionally harvested from the wild, is extremely rare and expensive — sometimes called "Himalayan gold."

You can find Cordyceps in various forms:

• Capsules or powders (for supplements)
• Teas and tinctures
• Functional foods (added to coffee, energy bars, or smoothies)

When choosing a Cordyceps product, always look for lab-tested and high-quality sources to ensure purity and potency.

🎮 Why Cordyceps Captivates the Imagination

There’s something deeply unsettling yet fascinating about a fungus that can control the behavior of its host. This idea taps into primal fears of losing control over one’s own body and mind. That’s what made Cordyceps the perfect inspiration for a post-apocalyptic world in The Last of Us.

But beyond the horror lies real science — showcasing how nature often holds secrets that are stranger (and scarier) than fiction.

Cordyceps is one of nature’s most fascinating organisms — a killer in the insect world, a healer in traditional medicine, and an icon of modern horror fiction. Its unique life cycle and health properties have placed it at the intersection of biology, culture, and entertainment.

Thanks to The Last of Us, people around the world are asking: “Is Cordyceps real?” The answer is yes — but not (yet) in the way it appears in the game.

So, the next time you enjoy a Cordyceps-infused smoothie or watch an infected character sprint across the screen, remember: behind the fiction lies a very real and remarkable fungus.
