Cordyceps
Also known as: Cordyceps militaris, Cordyceps sinensis, caterpillar fungus, Dong Chong Xia Cao, cordycepin
Effective Dosage
No established dose from provided studies
What the Science Says
Cordyceps is a parasitic fungus used for centuries in traditional Chinese medicine. Early clinical research suggests it may modestly boost immune cell activity (particularly NK cells) and help reduce flare-ups in people with COPD when used alongside standard treatment. Its key active compound, cordycepin, has shown anti-inflammatory effects in lab and animal studies, but robust human trials are still limited.
What It Doesn't Do
Not proven to boost athletic performance or endurance in humans based on these studies. No solid evidence it fights cancer in people — animal and lab findings don't translate directly. Won't replace standard COPD medications. Skin-lightening effects only tested when combined with other active ingredients, so Cordyceps alone gets no credit there. Claims about testosterone or libido enhancement are not supported by any provided data.
Evidence-Based Benefits
Cordyceps militaris beverage containing cordycepin showed modest NK cell activity increases and reductions in IL-1β and IL-6 in a small RCT (n=20, PMID: 38580687). Cordyceps-based capsules (YChCC) reduced acute exacerbation frequency and prolonged time to first exacerbation in COPD patients compared to an active comparator, though lung function parameters were unchanged (PMID: 41295088). Topical Cordyceps extract improved melasma severity comparably to hydroquinone cream with fewer adverse reactions (PMID: 40590148).

Absorption & Bioavailability
Unknown — no pharmacokinetic data provided in the reviewed studies. Cordycepin (the key active compound) is present in measurable amounts in fermented beverages, but absorption rates in humans are not characterized in these papers.
Red Flags to Watch For
- Most human trials are small (n=10–62 per group) and short-term — don't over-interpret results
- Many products combine Cordyceps with other herbs, making it impossible to isolate its effects
- Wild-harvested Cordyceps sinensis is extremely expensive and frequently adulterated — lab-grown Cordyceps militaris is the more reliable commercial source
- No standardized dose exists; products vary widely in cordycepin content and potency
- Cancer-related claims are based on mouse models and cell studies only — no human trial data supports anti-cancer use
