What You'll Learn
Cordyceps mushrooms are a genus of fungi
Cordyceps mushrooms, also known as "zombie fungus", are a genus of ascomycete fungi (sac fungi) that includes over 260 species worldwide, many of which are parasitic. They are non-poisonous mushrooms that parasitise insects for growth and development by manipulating the host system, causing it to behave like a "zombie". Cordyceps has been used in traditional Chinese medicine for over 1,500 years due to its health benefits, such as boosting stamina, appetite, immunity, longevity, libido, memory, and sleep. It is also believed to have neuroprotective properties and is being studied for its potential to treat neurodegenerative diseases.
In nature, Cordyceps spores infect insects, take over their bodies and minds, kill them, and eventually sprout mushrooms through their heads. This process is species-specific, and there is no evidence that Cordyceps can infect humans in the same way. The variety commonly used in wellness products and supplements is Cordyceps militaris, which is cultivated in controlled environments without the use of insects. It is known to support natural energy, help with endurance, and promote overall vitality when used as part of a balanced lifestyle.
Cordyceps is a rich source of over 200 bioactive compounds, including nucleotides, nucleosides, polysaccharides, proteins, sterols, vitamins, and trace elements. These bioactive compounds exhibit a range of pharmacological activities, including antimicrobial, anti-allergic, antidiabetic, analgesic, anti-inflammatory, antioxidant, anti-aging, and immunomodulatory effects. The nucleoside cordycepin, isolated from C. militaris, is of particular interest due to its potential therapeutic benefits.
While Cordyceps has a long history of use in Eastern and traditional medicine, it has gained popularity in modern times as a functional food and health supplement. It is often included in foods, energy drinks, and supplements to support energy, stamina, and overall health. However, it is important to note that Cordyceps is not a quick fix and should be used regularly as part of a balanced lifestyle. Side effects are rare, but caution should be exercised, especially for individuals with allergies to fungi, mould, or penicillin.

They are also known as 'zombie fungus'
Cordyceps mushrooms are a unique type of fungus that has some fascinating and somewhat sinister characteristics, earning them the nickname "zombie fungus". This moniker originates from the fungus' ability to manipulate and control the behaviour of its insect hosts, turning them into mindless, walking zombies. The Cordyceps fungus is an entomopathogenic fungus, which means it specifically infects and parasitizes insects, manipulating their behaviour in a way that ensures the fungus' survival and propagation.
The life cycle of Cordyceps begins when its spores come into contact with an insect host, typically a specific species of ant, beetle, or moth. Once infected, the fungus invades the insect's body and releases chemicals that alter its behaviour. The fungus takes control of the insect's nervous system, affecting its movement and decision-making abilities. One of the most well-known examples of this behaviour manipulation is observed in ants. Cordyceps can infect ants and cause them to leave their colonies and climb up plants, usually to a specific height or location that provides the optimal temperature and humidity for the fungus to thrive.
Once the infected ant has reached the desired spot, the fungus triggers the ant to bite down on the vein of a leaf or another part of the plant, securing itself in place. This behaviour ensures that the Cordyceps fungus has a stable platform to grow and develop. After the ant dies, the fungus continues to grow, often producing a long, slender stalk that protrudes from the insect's body. This stalk, known as a stroma, is the fungus' fruiting body, and it releases spores to infect other insects, continuing the cycle.
The process by which Cordyceps manipulates its insect hosts is a remarkable example of the intricate relationship between fungi and their environments. While the "zombie fungus" nickname may evoke images of horror and science fiction, it is a testament to the complex and adaptive strategies that fungi have evolved to ensure their survival and propagation in the natural world.

They are used in traditional medicine
Cordyceps mushrooms, also known as "zombie fungus", are a non-poisonous variety of mushrooms that parasitise insects for growth and development. They manipulate the host system, making the victim behave like a "zombie". While there are over 260 species in the Cordyceps genus, only 35 have been characterised. Of these, C. militaris and C. sinensis are the two most widely studied. C. sinensis is a rare species that is challenging to cultivate, while C. militaris is a commercially successful species grown in controlled environments without insects.
Cordyceps have been used in traditional medicine due to their numerous health benefits. They have been a part of Chinese medicine for over 1,500 years. The mushroom is rich in bioactive compounds, including nucleotides, nucleosides, polysaccharides, proteins, sterols, vitamins (Vit E, K, B1, B2, and B12), and trace elements. These compounds are associated with a range of pharmacological activities, including antimicrobial, anti-allergic, antidiabetic, analgesic, anti-apoptotic, anticancer, anti-inflammatory, antioxidant, anti-aging, and immunomodulatory effects.
In traditional Chinese medicine, Cordyceps is believed to treat various diseases, although there is limited scientific evidence to support these claims. However, basic studies have shown that Cordyceps can strengthen the immune response, making it valuable in preventive and support therapies for chronic diseases. It is also used to improve physical performance and reduce fatigue, especially for athletes. The fungus increases maximum oxygen uptake and promotes fat burning, improving endurance and accelerating post-workout recovery.
Cordyceps are available in various forms, including capsules, powders, and blends with chocolate or cacao. While generally safe, they may cause allergies, nausea, and stomach aches in some cases. It is recommended to consult a doctor before consuming Cordyceps, especially when taking certain medications, to avoid potential interactions.
