Cordyceps militaris continues to attract scientific attention for its unusual chemistry. In May 2025, researchers publishing in the Journal of Natural Products reported the discovery of three previously undescribed compounds from this fungus.
The compounds demonstrated activity in laboratory experiments involving inflammatory signaling. These results offer an interesting direction for future research, but they do not demonstrate that consuming Cordyceps supplements reduces inflammation or treats inflammatory diseases in humans.
At Purest Mushrooms, we believe the most compelling scientific story is an accurate one. Here is what researchers discovered, what the findings mean, and why the distinction between an isolated molecule and a finished mushroom supplement matters.
What Did the 2025 Cordyceps Study Discover?
Researchers led by Zhi-Ang Chen identified three unusual compounds from Cordyceps militaris, which they named cordycepsterols A, B, and C.
These compounds are C30 ergosterol derivatives possessing an uncommon five-ring structure, described as a 6/6/6/5/6-fused pentacyclic system.
This molecular architecture is significant from a natural-products chemistry perspective because it expands the catalog of compounds scientists have identified in Cordyceps militaris.
The research team established the structures using spectroscopic methods and computational chemistry.
What Happened During Laboratory Testing?
The investigators examined how the isolated compounds affected nitric oxide production in an experimental model.
They reported half-maximal inhibitory concentrations (IC50) of:
- Cordycepsterol A: 3.0 µM
- Cordycepsterol B: 0.9 µM
- Cordycepsterol C: 2.3 µM
At a tested concentration of 5 µM, the compounds also reduced secretion of two signaling proteins associated with inflammatory processes: tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6).
These findings suggest that the isolated molecules warrant further investigation for their biological activity.
However, these measurements describe laboratory concentrations, not human supplement doses. They cannot be translated into a recommended number of mushroom tablets or scoops of extract powder.
The study did not test Purest products, evaluate oral absorption in humans, or establish whether these compounds occur in Purest's finished extracts at measurable concentrations.

Does This Mean Cordyceps Reduces Inflammation?
Not necessarily.
Inflammation is a complex biological response involving immune cells, signaling molecules, and numerous regulatory pathways. Measurements of particular signaling markers can be useful in research, but they do not independently establish clinical outcomes.
In the 2025 study, researchers evaluated isolated compounds in laboratory experiments. They did not conduct a human clinical trial to determine whether consuming Cordyceps improves inflammatory symptoms or diseases.
Several important questions remain unanswered:
- How much of each compound occurs naturally in different Cordyceps materials?
- Do ordinary mushroom extraction processes recover these compounds?
- Are the compounds absorbed after oral consumption?
- What concentrations, if any, reach relevant human tissues?
- What are the safety characteristics of these isolated molecules?
- Would any laboratory activity translate into meaningful human clinical outcomes?
Until these questions are investigated, the findings should be interpreted as early-stage experimental research rather than evidence of an established anti-inflammatory benefit from commercial Cordyceps supplements.
Understanding the Difference Between Laboratory, Animal, and Human Research
Scientific studies can investigate mushrooms at several levels, from individual molecules to whole organisms.
Isolated-Compound Research
Scientists isolate specific molecules to understand their chemical structure and investigate their biological activity under controlled experimental conditions.
The cordycepsterol discovery study belongs in this category. Its findings cannot automatically be generalized to whole mushrooms or commercial extracts.
Animal Research
Animal studies allow researchers to investigate biological processes within a living organism. They can reveal information that laboratory cell experiments cannot, but results may not translate directly to humans.
A separate paper, published online in January 2025 in Frontiers in Immunology, investigated a Cordyceps militaris solid-medium extract in mice with experimentally induced acute lung injury.
The researchers examined inflammatory markers, lung tissue changes, gut microbiota, and metabolic pathways.
They reported several favorable changes in the experimental mice. However, this was an animal study involving a particular experimental preparation, not a human clinical trial or a test of Purest's products.
Read the separate animal study by Wang and colleagues.
Human Clinical Research
Human clinical studies are needed to determine whether a particular intervention has meaningful effects in people and to investigate relevant safety questions.
The two studies discussed here do not establish clinical effectiveness of Purest Cordyceps tablets, powders, or any other retail Cordyceps supplement for inflammatory conditions.
Why the Mushroom Material Matters
Researchers can investigate several different types of material derived from Cordyceps militaris:
- Isolated chemical compounds
- Cultivated fruiting bodies
- Fungal mycelium
- Myceliated substrates or solid-medium extracts
- Hot-water extracts
- Alcohol extracts and dual extracts
- Finished commercial supplements
These materials are related, but they are not chemically identical.
For example, a study of a solid-medium extract should not be presented as direct evidence for the effects of a fruiting-body supplement.
Similarly, the discovery of an isolated molecule does not establish that it is present at a meaningful concentration in every preparation derived from the same mushroom species.
Scientific accuracy requires identifying what was actually tested.
How Purest Approaches Cordyceps Quality
Purest's Cordyceps products are formulated using Cordyceps militaris fruiting-body extract.
Our formulation approach emphasizes clearly identified mushroom material, straightforward ingredient declarations, extraction transparency, and laboratory-supported quality evaluation.
Importantly, Purest offers two distinct Cordyceps preparations:
- Cordyceps Tablets: Made using hot-water and alcohol dual extraction.
- Cordyceps Powder: Made using hot-water extraction.
These processes can recover different groups of mushroom constituents. Neither method automatically establishes superior clinical outcomes.
We also avoid unnecessary fillers and binders in our individual mushroom tablet formulas.
Our Cordyceps tablets contain 500 mg of extract per tablet. Two tablets provide the standard labeled 1,000 mg serving, with 60 tablets per bottle.
These are product formulation and serving details. They should not be interpreted as evidence that our tablets contain the newly discovered cordycepsterols or reproduce the activity reported in the 2025 study.

Cordyceps Tablets vs. Powder: What Should You Compare?
The choice between tablets and powder can depend on convenience, preparation preferences, and the specific extract formulation.
| Consideration | Purest Cordyceps Tablets | Purest Cordyceps Powder |
|---|---|---|
| Species | Cordyceps militaris | Cordyceps militaris |
| Source | Fruiting body | Fruiting body |
| Extraction | Hot water and alcohol | Hot water |
| Serving | Pre-portioned tablets | Measured according to the powder label |
| Convenience | Portable and easy to use | Flexible for mixing into beverages and food |
| Evidence for Inflammation | Not established by the 2025 studies discussed here | Not established by the 2025 studies discussed here |
Neither physical format should be considered inherently more effective without appropriate comparative evidence.

What Extraction Methods Can and Cannot Tell Us
Extraction is a manufacturing process that helps recover selected constituents from mushroom material.
Hot-water extraction primarily targets water-soluble constituents, while alcohol extraction can recover compounds with different solubility characteristics.
Dual extraction incorporates both steps, but this does not automatically establish higher potency, better absorption, or superior health outcomes.
Most importantly, neither extraction method alone confirms whether a finished product contains cordycepsterols A, B, or C.
Identifying and measuring those compounds in a particular extract would require appropriate analytical testing.
Until such product-specific evidence is available, the 2025 cordycepsterol findings should remain separate from claims about Purest's finished products.
How to Choose a Cordyceps Supplement
When comparing Cordyceps supplements, consider the following:
- Confirm the species: Determine whether the product contains Cordyceps militaris, Ophiocordyceps sinensis, or another preparation.
- Identify the source material: Look for clear disclosure of fruiting body, mycelium, or other fungal material.
- Review extraction methods: Understand whether water, alcohol, or multiple extraction steps were used.
- Check the ingredients: Review the entire ingredient list, including any binders, grains, or other additions.
- Understand the serving: Compare the actual labeled quantity and preparation, not simply the largest milligram number.
- Look for laboratory documentation: Review which compounds or contaminants were measured and whether the test applies to the relevant product or batch.
- Evaluate scientific claims: Distinguish isolated-compound studies from human clinical research.

Safety and Practical Considerations
Cordyceps supplements may not be suitable for everyone. Human safety and interaction evidence varies by preparation and remains incomplete for many concentrated extracts.
People taking medications, managing medical conditions, preparing for surgery, or considering supplementation during pregnancy or nursing should consult a qualified healthcare professional.
Use Purest Cordyceps products according to their current Suggested Use instructions.
Do not increase a serving to attempt to reproduce an experimental laboratory concentration or to treat inflammation or an inflammatory flare-up.
Frequently Asked Questions
Does Cordyceps reduce inflammation?
Some laboratory and animal studies have reported activity involving inflammatory signaling pathways. However, the studies discussed in this article do not establish that commercial Cordyceps supplements reduce inflammation or treat inflammatory diseases in humans.
What are cordycepsterols A, B, and C?
They are three unusual ergosterol-derived compounds isolated from Cordyceps militaris and reported by researchers in 2025. Their distinctive chemical structures and laboratory activity make them subjects of scientific interest.
Are cordycepsterols the same as cordycepin?
No. Cordycepsterols are steroid-derived compounds with a distinctive ring structure. Cordycepin is a different molecule, also known as 3'-deoxyadenosine. Research findings involving one should not be attributed to the other.
Does Purest Cordyceps contain the newly discovered compounds?
The presence and quantity of cordycepsterols A–C have not been established for Purest's finished products in the evidence discussed here. The discovery of these compounds in Cordyceps militaris does not prove that a particular commercial extract contains measurable amounts.
Are Cordyceps tablets or powders better?
Neither format is automatically better. Purest's Cordyceps tablets use hot-water and alcohol dual extraction, while the powder uses hot-water extraction. Compare their labeled ingredients, preparation methods, serving information, and convenience.
Can the 2025 study tell me how much Cordyceps to take?
No. The reported micromolar concentrations are experimental laboratory measurements, not human doses. They cannot be used to calculate an appropriate supplement serving.
Conclusion: Scientific Curiosity Without Overstatement
The 2025 discovery of cordycepsterols A, B, and C adds an interesting chapter to the scientific understanding of Cordyceps militaris.
It demonstrates that researchers are continuing to identify previously undescribed fungal compounds and investigate their biological properties.
But the distinction between a laboratory experiment and a finished supplement remains essential.
At Purest Mushrooms, our approach centers on clear ingredient identity, thoughtful extraction, and transparent product information.
We believe customers should understand both the potential of emerging mushroom research and the limits of what the evidence actually demonstrates.
