Caterpillar Fungus (Cordyceps sinensis): Benefits, Dosage, Safety & Evidence

Questions fréquentes

How does Cordyceps sinensis work to improve energy?

Cordyceps sinensis improves energy by increasing the production of adenosine triphosphate (ATP), which is essential for delivering oxygen to muscles and supporting cellular energy. The active compound cordycepin is structurally similar to adenosine and appears to enhance mitochondrial function and oxygen utilization. This mechanism supports its traditional use for fatigue and stamina, though clinical evidence is currently limited (Evidence Level: C).

Does Cordyceps interact with immunosuppressant medications?

Yes, Cordyceps poses a significant interaction risk with immunosuppressants. Because the fungus stimulates immune activity through its polysaccharide content, it may counteract the effects of drugs prescribed to suppress the immune system, such as those used after organ transplants or for autoimmune diseases. Patients on immunosuppressive therapy should avoid Cordyceps to prevent potential treatment failure or disease flare-ups.

What is the recommended daily dosage for Cordyceps?

For the wild-harvested Cordyceps sinensis, the traditional dosage is 1 to 3 grams of the dried fungus daily. For standardized extracts, often derived from the cultivated Cordyceps militaris species, a common dosage is 400 mg taken twice daily. Users should verify whether they are consuming wild or cultivated forms, as potency varies, and adhere to specific product label instructions.

Is Cordyceps safe to take during pregnancy?

No, Cordyceps is considered unsafe during pregnancy and breastfeeding. There is insufficient safety data to support its use for expecting mothers, and its potential hormonal and immune-modulating effects pose theoretical risks to the fetus. Traditional medical texts also advise against its use in these populations. Women who are pregnant or nursing should avoid this supplement entirely.

What is Cordyceps used for in traditional medicine?

In Traditional Chinese Medicine (TCM) and Tibetan medicine, Cordyceps is primarily used as a tonic for kidney and lung deficiency. It is prescribed to strengthen the respiratory system, enhance sexual vitality, and aid recovery from chronic fatigue or long-term illness. Considered a precious adaptogen, it helps the body resist physical stress, though robust clinical trials are still needed to confirm these uses (Evidence Level: C).

Résumé

Cordyceps sinensis, also known as Ophiocordyceps sinensis or 'winter worm-summer grass', is a highly valued medicinal fungus used in traditional Tibetan and Chinese medicine [PMID:24716152, PMID:29371523].

Contexte

It is an entomogenous, endoparasitic fungus that parasitizes the larvae of moths (Lepidoptera) [PMID:29371523, PMID:32288794, PMID:25704018]. It is primarily found on the Tibetan Plateau and in the Himalayan region [PMID:30394122, PMID:39331691].

Usages traditionnels

Used in traditional Tibetan and Chinese medicine as a prestigious tonic and therapeutic herb [PMID:24716152, PMID:32362940]. It is traditionally used to tonify the lung and kidney [PMID:35645822, PMID:38375041] and as a tonic supplement for sexual and reproductive dysfunctions [PMID:28911537].

Composés actifs

Bioactive ingredients include polysaccharides (extracellular and intracellular), nucleosides (such as cordycepin, adenosine, guanine, guanosine, hypoxanthine, uridine, inosine, thymidine, and adenine), sterols, proteins, amino acids, polypeptides, and specific compounds like cordysinin (A-E) and epipolythiodioxopiperazines (gliocladicillins A and B) [PMID:24716152, PMID:39519748, PMID:32288794, PMID:25960753, PMID:27874103].

Mécanisme d'action

Mechanisms include immunomodulatory, anti-inflammatory, antioxidant, and anti-apoptotic activities [PMID:24716152, PMID:25960753]. Cordycepin specifically may exert anticancer effects via stimulation of the adenosine A3 receptor, leading to glycogen synthase kinase (GSK)-3β activation and cyclin D1 suppression [PMID:25704018]. It also demonstrates anti-proliferative and vasorelaxant properties in pulmonary artery smooth muscle cells [PMID:32188043].

Preuves cliniques

Preuve AChronic Obstructive Pulmonary Disease (COPD)

Bailing capsules (derived from C. sinensis) significantly improved forced expiratory volume in 1s (FEV1), FEV1/FVC ratio, and 6-min walk test (6MWT) results [PMID:39460586].

Preuve BChronic Bronchitis (CB)

Bailing capsule significantly reduced the frequency of acute exacerbation of CB compared with placebo [PMID:39193337].

Preuve AHemodialysis

Adjunctive use of cordyceps or fermented products significantly improved C-reactive protein levels [PMID:32186018].

Preuve AChronic Kidney Disease (CKD)

Used as a common ingredient for treatment, though a systematic review aimed to evaluate therapeutic and adverse effects [PMID:25519252].

Preuve AKidney Transplant

Evaluated as an adjuvant immunosuppressive agent to assess graft rejection and survival rates [PMID:28137532].

Sécurité et effets indésirables

C. sinensis is suggested to have minimal side effects [PMID:39331691]. One study on Bailing capsules for chronic bronchitis assessed safety alongside efficacy [PMID:39193337].

Synthèse des preuves

Evidence ranges from high-level meta-analyses for respiratory and renal adjunctive therapies to review-level data on biochemical constituents and animal/in-vitro models for inflammation and cancer.
