In the Nordic wilds, energy flows from nature’s pulse — crisp air, ancient forests, and the steady rhythm of enduring strength.
Cordyceps sinensis, a revered functional mushroom, channels this vitality into a modern ritual for stamina, focus, and balance.
At Medshrum, we’ve harnessed this tradition through our Soil Association certified, ultrasonic triple-extracted Cordyceps tincture — delivering clean, sustained energy without the jitters of caffeine.
Whether you’re powering through a workout or seeking calm focus, our tincture connects you to nature’s enduring energy.
What Is Cordyceps sinensis?
Cordyceps sinensis is a parasitic fungus long prized in Traditional Chinese Medicine for supporting oxygen use, recovery and steady energy. Wild Cordyceps from high-altitude regions is now rare and unsustainable; modern supplements use cultivated strains.
Medshrum’s Cordyceps is organically cultivated in controlled Nordic environments to ensure purity, sustainability and full traceability.
Note: wild C. sinensis is rare and unsustainable to harvest. Our tincture uses a cultivated, organic strain grown in clean, controlled facilities. This sustainable, lab-optimised form contains the key compounds associated with Cordyceps — including cordycepin, adenosine and beta-glucans — providing a consistent, ethical alternative.
Classic research and reviews outline Cordyceps’ bioactives and traditional use, alongside modern preparations (see Zhu et al., 1998; LBS, NCBI).

Active Compounds: Nature’s Energy Toolkit
- Cordycepin — linked with ATP (energy) dynamics and anti-fatigue effects (Cheng et al., 2025).
- Polysaccharides (beta-glucans) — studied for immune modulation and general resilience (LBS, NCBI).
- Adenosine — supports cellular energy and oxygen utilisation (Zhu et al., 1998).
- Sterols & peptides — contribute to antioxidant capacity and recovery (Zhu et al., 1998).
Extraction matters. That’s why Medshrum’s ultrasonic-assisted triple extraction (hot water + alcohol + ultrasound) is designed for high compound availability. Our process targets broad-spectrum extraction of water- and alcohol-soluble molecules for better practical uptake.
The Science Behind Cordyceps
Cordycepin supports cellular energy pathways (mitochondrial ATP). Beta-glucans modulate immune responses, while adenosine is involved in oxygen use and cellular signalling. Together, these mechanisms help explain Cordyceps’ steady-energy reputation in traditional use and modern studies (Zhu et al., 1998).
What the Research Suggests
Cordyceps is a functional food, not a medicine. Early human and preclinical studies suggest:
Energy & Endurance
Improved tolerance to high-intensity exercise has been reported with C. militaris supplementation in trained adults (Hirsch et al., 2017).
Performance & Recovery
Cordycepin with antioxidant support reduced exercise-induced fatigue in a controlled study (Cheng et al., 2025).
Stress Support
Hot-water mycelial fractions showed antifatigue and antistress effects in experimental models (Koh et al., Biological & Pharmaceutical Bulletin).
Immune Balance & Post-viral Support
Reviews describe immunomodulatory potential of Cordyceps (LBS, NCBI). A randomised, waitlist-controlled trial reported symptom support in individuals with long COVID using a CS-4 mycelium extract (Chen et al., 2025).

Frequently Asked Questions
What is Cordyceps?
A functional fungus traditionally used for stamina, resilience and recovery. Modern products use cultivated strains for sustainability. See overview: LBS, NCBI.
Can Cordyceps infect humans (like in The Last of Us)?
No. The “zombie fungus” storyline is fiction. Cordyceps species that affect insects do not infect humans. Medshrum uses cultivated, food-grade extracts.
What are the main benefits people seek?
Steady energy, exercise tolerance, recovery and immune balance — based on early human data and preclinical studies (Hirsch et al., 2017; Cheng et al., 2025; LBS, NCBI).
How do I take Medshrum’s Cordyceps tincture?
Take 2 ml daily under the tongue or in water/tea/coffee. Morning or 30–60 minutes pre-workout works well for many.
How long does it take to notice effects?
Some feel a lift around training; others notice more stable energy after 1–2 weeks. Adaptogenic effects tend to build over 4–8 weeks (individual results vary).
Is it safe to take daily?
Generally well-tolerated when used as directed. Speak to your GP if pregnant/breastfeeding, on medicines (e.g., anticoagulants, immunosuppressants, diabetes meds) or managing medical conditions.
Who should avoid Cordyceps?
People who are pregnant/breastfeeding, or with autoimmune/bleeding disorders, should consult a GP and may be advised to avoid use.
Are there side effects?
Occasionally mild digestive upset when starting; some feel more energised (avoid late-evening doses).
What’s different about Medshrum’s extraction?
Ultrasonic-assisted triple extraction targets broad-spectrum compounds (water- and alcohol-soluble) to support practical uptake.
Is Medshrum Cordyceps organic?
What about long COVID?
A randomised, waitlist-controlled study in Hong Kong investigated a CS-4 mycelium extract for persistent symptoms (Chen et al., 2025). This is exploratory and not a medical recommendation.
Sinensis vs. militaris — which is better?
Both are used in research. C. militaris has human exercise data (Hirsch et al., 2017), while C. sinensis (including CS-4) features in traditional use and modern preparations (Zhu et al., 1998; Chen et al., 2025).
Is it vegan?
Yes — our cultivated Cordyceps and extraction process are plant-based.
What should I look for in a quality product?
Organic certification, transparent sourcing, sensible extraction, and third-party testing.
Can I combine with other mushrooms?
Common pairings include Lion’s Mane (focus) and Reishi (rest). If you take medicines, check with your GP.
How should I store the tincture?
Keep sealed in a cool, dry place away from direct sunlight.
How does Medshrum verify quality?
We use certified organic supply, controlled cultivation, triple extraction, and third-party testing for quality and safety.
Where can I buy in the UK?
