• Athletic performance. Taking cordyceps orally does not seem to improve athletic performance in adults. Details: One small clinical study in endurance-trained cyclists shows that taking a specific mycelial fermentation product of cordyceps (CordyMax Cs-4) 3.15 grams daily for 5 weeks does not improve endurance time trials or aerobic capacity when compared with placebo (12095). Another small study in healthy elderly adults shows that taking the same cordyceps preparation (CordyMax Cs-4) 3 grams daily for 12 weeks does not improve exercise performance when compared with placebo (46120). Research also shows that taking combination products containing cordyceps and other ingredients does not improve athletic performance when compared with control. These products have combined cordyceps (CordyMax Cs-4) 1000 mg with rhodiola 300 mg (46091) or cordyceps (CordyMax Cs-4) 2000 mg with roseroot 600 mg (Optygen, First Endurance) (15573); liquid and powdered cordyceps formulations with reishi mushroom, shiitake mushroom, bamboo, and honey (Fohow oral liquid and Fohow lingzhi capsules, FOHOW Technology Investment Group Co. Ltd.) (98686); and cordyceps (form unknown) 1.2 grams with a 930 mg mixture of extracts of ashwagandha root, green tea leaf, rhodiola root, and astragalus root (Shroom Tech Sport, Onnit Labs) (105079).

• Arrhythmia. Although there is interest in using oral cordyceps for arrhythmia, there is insufficient reliable information about the clinical effects of cordyceps for this condition.
• Asthma. Oral cordyceps has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in children with asthma shows that a 619 mg capsule containing equal weights of the dried aqueous extracts of cordyceps, astragalus, skullcap, Radix stemonae, and Bulbus fritillariae daily for 6 months does not reduce the need for medication or improve symptoms when compared with placebo (32935).
• Chronic kidney disease (CKD). Small clinical studies suggest that oral cordyceps may modestly improve biomarkers in some patients with CKD. Details: A meta-analysis of clinical research in patients in China with CKD shows that taking cordyceps 0.6-2 grams orally three times daily, along with standard treatment, seems to decrease serum creatinine levels by 0.6 mg/dL and increase creatinine clearance by 9.2 mL/min when compared with standard treatment alone (92829). Another meta-analysis of clinical studies in patients in China with diabetic kidney disease shows that taking cordyceps 0.5-2 grams orally three times daily along with angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) decreases blood urea nitrogen by 2 mg/dL and decreases serum creatinine levels by 0.1 mg/dL when compared with ACEI/ARB treatment alone (92830). Most individual studies in these analyses used Bailing (Cs-C-Q80) or Jinshuibao (Cs-4), fermented cordyceps mycelial products (92829,92830). Both of these analyses are limited by the low methodological quality and short duration (usually 1-6 months) of most of the included studies.
• Chronic obstructive pulmonary disease (COPD). Preliminary clinical studies suggest that oral cordyceps may modestly improve symptoms of COPD. Details: A meta-analysis of preliminary clinical research in patients with moderate or severe COPD shows that taking cordyceps alone or as part of a formulation containing other products for up to 12 months improves lung function and reduces the incidence of an acute exacerbation by a small amount. Also, the distance walked in 6 minutes is increased by about 45 meters, which was considered clinically meaningful. Most individual studies in this analysis used Bailing (Cs-C-Q80) or Jinshuibao (Cs-4), fermented cordyceps mycelial products, in combination with conventional treatments with conventional treatments alone (109705). This analysis is limited by the low methodological quality of the included studies.
• Contrast induced nephropathy. Small clinical studies suggest that oral cordyceps may modestly reduce contrast induced nephropathy. Details: A preliminary clinical study in patients with diabetic nephropathy shows that taking a specific cordyceps mycelial product (Corbrin; CS-C-Q80) 2-3 grams orally three times daily for 3 days before and after angiography reduces the risk of contrast induced nephropathy by about 48% to 66% when compared to standard treatment (92827). However, other preliminary clinical research in patients with stable angina pectoris shows that taking the same cordyceps product 3 grams orally three times daily for 3 days before and after angioplasty does not decrease the prevalence of contrast induced nephropathy when compared to standard therapy (92826). Reasons for these discrepancies are not clear but may relate to the small size and heterogenous populations in these studies.
• Diabetic nephropathy. Early research suggests that oral cordyceps may modestly improve kidney function in patients with diabetic kidney disease. Details: A meta-analysis of low to moderate quality clinical research in patients with diabetic kidney disease shows that taking cordyceps as adjunctive therapy to angiotensin-converting enzyme inhibitors or angiotensin receptor blockers for 2-24 weeks modestly improves kidney function when compared to these medications alone. Kidney function was based on markers such as blood creatinine and urea nitrogen, as well as urinary albumin and total protein. There were also modest improvements in systolic and diastolic blood pressure, triglycerides, and low-density lipoprotein (LDL) cholesterol. There was no effect on glycemic indices. The effect of cordyceps on disease progression or cardiovascular events is unclear (111903).
• Cough. Although there is interest in using oral cordyceps for cough, there is insufficient reliable information about the clinical effects of cordyceps for this purpose.
• Fatigue. Although there is interest in using oral cordyceps for fatigue, there is insufficient reliable information about the clinical effects of cordyceps for this purpose.
• Hepatitis B. Although there is interest in using oral cordyceps for hepatitis B, there is insufficient reliable information about the clinical effects of cordyceps for this condition.
• Hypercholesterolemia. Although there is interest in using oral cordyceps for hypercholesterolemia, there is insufficient reliable information about the clinical effects of cordyceps for this condition.
• Kidney failure. Small clinical studies suggest that oral cordyceps may improve inflammatory markers in patients on hemodialysis. Details: A meta-analysis of small clinical trials in patients in China on hemodialysis suggests that adding cordyceps to standard treatment does not seem to improve serum creatinine levels but may improve certain markers of inflammation, such as C-reactive protein, when compared with placebo. Most individual studies in this analysis used Bailing (Cs-C-Q80) or Jinshuibao (Cs-4), fermented cordyceps mycelial products (105076).
• Kidney transplant. Small clinical studies suggest that oral cordyceps is no better than standard treatment in patients with kidney transplant. Details: A meta-analysis of 4 heterogeneous clinical trials evaluating patients in China immediately post-kidney transplant or patients with complications post-kidney transplant suggests that adding cordyceps to standard therapy with cyclosporine and steroids is no better than adding azathioprine 50-150 mg for improving overall survival or graft survival or reducing rejection risk. However, there was a non-significant trend to reduced risk of graft rejection in the cordyceps group (95905). A higher quality systematic review, which determined the available studies were too heterogeneous to pool together in a meta-analysis, suggests that adding cordyceps 3-6 grams to standard therapy daily is no better than azathioprine or cyclosporine for improving organ rejection, kidney function, or survival in patients after kidney transplant (92828). All individual studies in these analyses used Bailing (Cs-C-Q80) fermented cordyceps mycelial product (95905,92828).
• Sexual dysfunction. It is unclear if oral cordyceps is beneficial in patients with sexual dysfunction. Details: Preliminary clinical research shows that taking a specific mycelial fermentation product of cordyceps (CordyMax Cs-4) approximately 3 grams daily for 40 days can improve symptoms of hyposexuality in 66% of patients, compared with 32% of patients taking natural cordyceps and 24% of patients taking placebo (46145).
• Tinnitus. Although there is interest in using oral cordyceps for tinnitus, there is insufficient reliable information about the clinical effects of cordyceps for this condition. More evidence is needed to rate cordyceps for these uses.

• Cancer. Most clinical research shows that oral shark cartilage is not beneficial in people with advanced cancer. Details: Most clinical research shows that taking shark cartilage orally offers no benefit in people with advanced, previously-treated cancer, including breast, colorectal, lung, prostate, and brain cancers, and non-Hodgkin's lymphoma (2015,6716,6717,13086,17102,74731). These studies used shark cartilage powder (Cartilade, Cartilage USA; Benefin, Lane Labs) at doses of 1-1.3 grams/kg daily or 96 grams daily (2015,6717,13086) and shark cartilage extract (AE-941, Neovastat) (17102). Studies of shark cartilage in less advanced cancer have not been published.

• Age-related macular degeneration (AMD). Although there is interest in using oral shark cartilage for AMD, there is insufficient reliable information about the clinical effects of shark cartilage for this condition.
• Diabetic retinopathy. Although there is interest in using oral shark cartilage for diabetic retinopathy, there is insufficient reliable information about the clinical effects of shark cartilage for this condition.
• Kaposi sarcoma. It is unclear if oral shark cartilage is beneficial in patients with Kaposi sarcoma. Details: There is anecdotal evidence that taking shark cartilage orally, 3.75-4.5 grams daily divided into 3 doses, might decrease cutaneous Kaposi sarcoma lesions and increase histological regression (4938). Prospective clinical research is needed to confirm this finding.
• Osteoarthritis. Topical shark cartilage has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that applying a topical preparation of shark cartilage 140 mg, chondroitin sulfate 50 mg, glucosamine sulfate 30 mg, and camphor 32 mg per gram, as needed for up to 8 weeks, reduces osteoarthritis symptoms. However, any symptom relief is most likely due to the counterirritant effect of camphor and not the other ingredients (10327).
• Psoriasis. It is unclear if topical shark cartilage is beneficial in patients with psoriasis. Details: Preliminary clinical research in adults with plaque psoriasis shows that applying a specific solution of a shark cartilage extract (AE-941, Neovastat) topically, 30-240 mL to affected areas daily for up to 12 weeks, can improve the appearance of plaques and reduce itching when compared with baseline (4893,10399).
• Renal cell carcinoma. It is unclear if oral shark cartilage is beneficial in patients with renal cell carcinoma. Details: Preliminary clinical research shows that taking a specific solution of shark cartilage extract (AE-941, Neovastat), 60-240 mL daily orally, seems to increase survival in patients with advanced renal cell carcinoma (4894,10900). However, no further clinical evidence has been published, and this specific extract is no longer being evaluated for the treatment of renal cell carcinoma.
• Rheumatoid arthritis (RA). Although there is interest in using oral shark cartilage for RA, there is insufficient reliable information about the clinical effects of shark cartilage for this condition. More evidence is needed to rate shark cartilage for these uses.

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, cordyceps may increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.  Details In vitro and animal research suggests that cordyceps extract inhibits platelet aggregation and function (3429,46112). However, this interaction has not been reported in humans.

IMMUNOSUPPRESSANTS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Theoretically, concurrent use of cordyceps might interfere with immunosuppressive therapy.  Details Animal and in vitro research suggests that cordyceps stimulates the immune system (3403,3404,3414,3431,3432). However, limited clinical research suggests that taking cordyceps may lower the necessary therapeutic dose of the immunosuppressant cyclosporine (92828), which suggests that cordyceps may have an immunosuppressive effect.

TESTOSTERONE Interaction Rating = Minor Be watchful with this combination. Severity = Mild •  Occurrence = Possible •  Level of Evidence = D Theoretically, concurrent use of cordyceps and testosterone might have additive effects.  Details Animal research suggests that cordyceps can increase testosterone levels (46087). The clinical significance of this finding is unclear.

General ...Orally, cordyceps seems to be generally well tolerated when used for up to 1 year.
Most Common Adverse Effects:
Orally: Abdominal discomfort, constipation, diarrhea.

Gastrointestinal ...Orally, cordyceps has been associated with diarrhea, constipation, abdominal discomfort, dry mouth, and throat discomfort in clinical research. However, these events were uncommon, and in some cases symptoms could be reduced by taking cordyceps after eating (92829,105076,109705).

Hematologic ...Two cases of lead poisoning, characterized by loss of appetite and other symptoms, have been reported for patients taking cordyceps powder. After discontinuing cordyceps supplementation, both patients were treated with chelating agents (46135).

Hepatic ...There is a case report of acute cholestatic hepatitis probably associated with the use of a product containing cordyceps. The 64-year-old male was asymptomatic except for jaundice and laboratory markers and recovered once the supplement was stopped. However, it is unclear whether the hepatitis is associated with the cordyceps or with an unknown contaminant (109704).

Renal ...One case of a mild increase in serum creatinine level (< 30%) has been reported (95905).
