Origin

Tibetan Plateau, high altitudes of China, Nepal, Tibet; cultivated worldwide (C. militaris)

Safety Level

Safe

Overview

Cordyceps is a unique fungus that grows on caterpillars in the high Himalayan mountains. Wild Cordyceps sinensis is one of the most expensive and prized medicinal substances in Chinese medicine, costing more per gram than gold. Fortunately, cultivated Cordyceps militaris and mycelium (Cs-4) provide similar benefits at a much lower cost. Cordyceps is renowned for its energy-enhancing, athletic performance, immune-supporting, and anti-aging properties.

Health Benefits

Improves energy and reduces fatigue (ATP production, mitochondrial function)
Enhances athletic performance and endurance (VO2 max, oxygen utilization - moderate evidence)
Immune-modulating (stimulates immune cells - natural killer cells, macrophages)
Respiratory support: may improve lung function, asthma, bronchitis (traditional use for lungs)
Sexual health: may improve libido, erectile function, and fertility (male and female)
Anti-aging and longevity (telomere research, SIRT1 activation - preliminary)
Anti-inflammatory and antioxidant

Active Constituents

The key compounds responsible for this herb's therapeutic effects:

Cordycepin (3'-deoxyadenosine) - most famous active compound (higher in C. militaris)Polysaccharides (beta-glucans - immune-active)AdenosineCordycepic acid (D-mannitol)Ergosterol (precursor to vitamin D)Amino acids (all essential amino acids)Vitamins: B complex, E, KMinerals: selenium, zinc, iron, potassium, magnesiumSterols: beta-sitosterolNucleosides

Usage & Dosage

How to Use

Capsule, tablet, powder, tincture, tea, dual-extraction tincture, added to soups and broths, coffee alternative blends.

Suggested Dosage

Standardized extract (polysaccharides 20–40%): 1–3 g daily; capsules: 500–1000 mg 2–3x/day; powder: 2–5 g daily; tincture: 2–4 mL 2–3x/day. For athletic performance: take 1–2 hours before exercise. Best taken long-term. Cs-4 mycelium is the most researched form.

Quality & Storage

Harvest Season

Wild Cordyceps sinensis is harvested in summer (June–July) on the Tibetan Plateau at 3000–5000 m altitude. Cultivated Cordyceps militaris and mycelium are produced year-round in controlled environments. Wild-harvested C. sinensis is extremely expensive and often adulterated - cultivated products are more reliable and affordable.

Quality Indicators

Look for: cultivated C. militaris or Cs-4 mycelium (more reliable than wild C. sinensis), standardized polysaccharide content (20–40% is good), cordycepin content (higher is better), third-party testing for purity and heavy metals. Wild C. sinensis is frequently adulterated or fake - buy from extremely reputable sources if buying wild. Dual-extraction (hot water + alcohol) extracts provide the broadest range of active compounds.

Storage

Powder and capsules: airtight container in cool dry place, 1–2 years. Tinctures: cool dark place, 3–5 years. Protect from moisture, light, and heat. Cordyceps can absorb moisture from the air.

Safety Information

Contraindications

Pregnancy and breastfeeding (insufficient safety data - avoid)Bleeding disorders or upcoming surgery (may increase bleeding - mild)Autoimmune diseases (may stimulate immune system - use cautiously)Severe kidney or liver disease (high doses - consult practitioner)Children (insufficient data)Hormone-sensitive cancers (may have mild testosterone-like effects - controversial)Fever or acute infections (TCM concern: may "trap" pathogen - controversial)

Possible Side Effects

  • Generally well-tolerated and safe at recommended doses
  • Mild digestive upset (nausea, diarrhea, dry mouth) - especially when first starting
  • Insomnia or restlessness (when taken too late in day - energizing effect)
  • Headache (rare)
  • Allergic reaction (rare - more common with wild-harvested)
  • Increased libido or sexual energy (desirable for most, but note)
  • Very low toxicity; long history of safe use

Drug Interactions

  • Blood thinners (anticoagulants) - may increase bleeding risk (mild-moderate)
  • Diabetes medications (may lower blood sugar - monitor)
  • Immunosuppressants (may counteract effect)
  • Blood pressure medications (may lower blood pressure - mild)
  • Stimulants (additive energizing effect)
  • Moderate interaction potential
