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.

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