Power Mushrooms by Health Concerns

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Cancer. Although there is interest in using oral poria mushroom for cancer, there is insufficient reliable information about the clinical effects of poria mushroom for this condition.
• Chronic fatigue syndrome (CFS). Although there is interest in using oral poria mushroom for CFS, there is insufficient reliable information about the clinical effects of poria mushroom for this condition.
• Chronic kidney disease (CKD). Although there is interest in using oral poria mushroom for CKD, there is insufficient reliable information about the clinical effects of poria mushroom for this condition.
• Coronavirus disease 2019 (COVID-19). Although there has been interest in using oral poria mushroom for COVID-19, there is insufficient reliable information about the clinical effects of poria mushroom for this purpose.
• Dementia. Although there is interest in using oral poria mushroom for dementia, there is insufficient reliable information about the clinical effects of poria mushroom for this condition.
• Diabetes. Oral poria mushroom has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of generally small clinical trials in patients with type 2 diabetes shows that taking Chinese herbal medicine combinations containing poria mushroom for 2-24 weeks along with hypoglycemic medications modestly reduces fasting blood glucose and glycated hemoglobin levels when compared with control groups taking hypoglycemic agents only. There were also modest improvements in levels of triglycerides and low-density lipoprotein (LDL) cholesterol and in insulin sensitivity (111920). Given the large number of other ingredients in the available formulations, it is unclear if any beneficial effects are related to poria mushroom, other ingredients in the formulation, or their combination.
• Diarrhea. Although there is interest in using oral poria mushroom for diarrhea, there is insufficient reliable information about the clinical effects of poria mushroom for this condition.
• Endometriosis. Although there is interest in using oral poria mushroom for endometriosis, there is insufficient reliable information about the clinical effects of poria mushroom for this condition.
• Influenza. Oral poria mushroom has only been evaluated for influenza vaccine enhancement in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in healthy adults shows that taking a product containing poria mushroom extract, rosemary extract, and aloe gel powder twice daily for 28 days prior to and following an influenza vaccination does not affect upper respiratory tract illness symptoms, severity, duration, or medication-related use when compared with taking placebo (111921). It is unclear if this study was large enough to detect differences between groups. Also, the effect of poria mushroom itself on influenza vaccine enhancement is unclear.
• Tinnitus. Although there is interest in using oral poria mushroom for tinnitus, there is insufficient reliable information about the clinical effects of poria mushroom for this condition.
• Urinary tract infections (UTIs). Although there is interest in using oral poria mushroom for UTIs, there is insufficient reliable information about the clinical effects of poria mushroom for this use. More evidence is needed to rate poria mushroom for these uses.

ANTICHOLINERGIC DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, poria mushroom might decrease the clinical effects of anticholinergic drugs.  Details In animal research, poria mushroom essential oil reduces acetylcholinesterase activity (111917). This interaction has not been shown in humans.

CHOLINERGIC DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, poria mushroom might have additive effects when used with cholinergic drugs.  Details In animal research, poria mushroom essential oil reduces acetylcholinesterase activity (111917). This interaction has not been shown in humans.

CNS DEPRESSANTS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, taking poria mushroom extract may enhance the therapeutic and adverse effects of sedatives.  Details Animal research shows that poria mushroom extract has sedative properties (111916). This interaction has not been shown in humans.
