Maitake by Host Defense Organic Mushrooms

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Allergic rhinitis (hay fever). Although there has been interest in using oral maitake mushroom for allergic rhinitis, there is insufficient reliable information about the clinical effects of maitake mushroom for this purpose.

• Chemotherapy-induced diarrhea. Although there has been interest in using oral maitake mushroom for preventing chemotherapy-induced diarrhea, there is insufficient reliable information about the clinical effects of maitake mushroom for this purpose.
• Chemotherapy-related fatigue. Although there has been interest in using oral maitake mushroom for preventing chemotherapy-related fatigue, there is insufficient reliable information about the clinical effects of maitake mushroom for this purpose.
• Chemotherapy-induced leukopenia. Although there has been interest in using oral maitake mushroom for preventing chemotherapy-induced leukemia, there is insufficient reliable information about the clinical effects of maitake mushroom for this purpose.

• Coronavirus disease 2019 (COVID-19). Although there has been interest in using oral maitake mushroom for COVID-19, there is insufficient reliable information about the clinical effects of maitake mushroom for this purpose.
• Diabetes. Although there has been interest in using oral maitake mushroom for diabetes, there is insufficient reliable information about the clinical effects of maitake mushroom for this purpose.
• HIV/AIDS. Although there has been interest in using oral maitake mushroom for HIV/AIDS, there is insufficient reliable information about the clinical effects of maitake mushroom for this purpose.
• Hyperlipidemia. Although there has been interest in using oral maitake mushroom for hyperlipidemia, there is insufficient reliable information about the clinical effects of maitake mushroom for this purpose.
• Hypertension. Although there has been interest in using oral maitake mushroom for hypertension, there is insufficient reliable information about the clinical effects of maitake mushroom for this purpose.
• Laryngeal cancer. It is unclear if maitake mushroom is beneficial for improving quality of life in patients with laryngeal cancer. Details: Clinical research in patients with laryngeal or pharyngeal cancer undergoing chemo-radiation treatment shows that taking maitake mushroom polysaccharides D-fraction 1 gram 3 times daily during treatment modestly improve survival over 5 years and prevents the decline in overall quality of life when compared with taking placebo (111935).
• Myelodysplastic syndromes. Although there has been interest in using oral maitake mushroom for myelodysplastic syndromes, there is insufficient reliable information about the clinical effects of maitake mushroom for this purpose.
• Obesity. Although there has been interest in using oral maitake mushroom for obesity, there is insufficient reliable information about the clinical effects of maitake mushroom for this purpose.
• Pharyngeal cancer. It is unclear if maitake mushroom is beneficial for improving quality of life in patients with pharyngeal cancer. Details: Clinical research in patients with laryngeal or pharyngeal cancer undergoing chemo-radiation treatment shows that taking maitake mushroom polysaccharides D-fraction 1 gram 3 times daily during treatment modestly improve survival over 5 years and prevents the decline in overall quality of life when compared with taking placebo (111935).
• Polycystic ovary syndrome (PCOS). Maitake mushroom may have some benefit in PCOS, but it does not appear to be as effective as clomiphene. Details: Preliminary clinical research in patients with PCOS shows that taking three tablets of a specific combination product (SX-Fraction, Maitake Products, Inc.), each containing maitake mushroom powder 250 mg plus maitake SX-fraction (a glycoprotein-rich extract) 18 mg, three times daily starting on the first day of menses for up to 28 weeks, can improve ovulation cycle rates, but does not appear to be as effective as clomiphene. After 12 weeks of treatment, patients taking the maitake mushroom product had an ovulatory cycle rate of about 42% compared with about 70% in those taking clomiphene 50 mg daily. However, 13 out of 15 patients who failed monotherapy with maitake mushroom or clomiphene alone ovulated when both maitake mushroom and clomiphene were used for 4 cycles (17131). More evidence is needed to rate the effectiveness of maitake mushroom for these uses.

POSSIBLY SAFE ...when used orally and appropriately as extracts. A maitake mushroom extract 3 mg/kg twice daily has been used safely for up to 12 weeks (92843). Doses up to 5 mg/kg twice daily of another maitake mushroom extract have been used safely for up to 3 weeks (61239). Maitake mushroom polysaccharides (MMP) 1-1.5 grams daily have also been used safely for up to 2 years (8188).

PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.

ANTIDIABETES DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Theoretically, combining maitake mushroom with antidiabetes drugs might increase the risk of hypoglycemia.  Details Clinical research shows that taking maitake mushroom polysaccharide (MMP) can lower blood glucose levels in patients with types 2 diabetes (8188).

ANTIHYPERTENSIVE DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, combining maitake mushroom with antihypertensive drugs might increase the risk of hypotension.  Details Animal research shows that maitake mushroom can lower blood pressure (1213,1214,61226).

WARFARIN (Coumadin) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D There is limited evidence that maitake mushroom may increase the anticoagulant effects of warfarin.  Details In a case report, a patient previously stabilized on warfarin developed an elevated international normalized ratio (INR) of 5.1 after taking maitake mushroom (Grifron-Pro Maitake D-Fraction) 1 drop/kg daily in three divided doses for one week. The elevated INR resolved after holding warfarin for two days, then reducing the dose by 11%. It is thought that the beta-glucan constituent of maitake mushroom might cause warfarin dissociation from proteins, resulting in increased free warfarin levels and increased warfarin effects (17209).
