Below is general information about the safety of the known ingredients contained in the product Mushroom Master Blend. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
POSSIBLY SAFE ...when used orally and appropriately. Agaricus mushroom extract has been safely used in doses up to 1500 mg daily for up to 12 months (15404,15421,94715,94716,94719,94721). A specific agaricus lyophilized powder product (Sen-Sei-Ro Powder Gold, Kyowa Wellness Co., Ltd.) has been safely used in doses up to 5.4 grams daily for 6 months (17185).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately. Doses of astragalus up to 60 grams daily for up to 4 months have been used without reported adverse effects (32920,33038,95909,114804). ...when used intravenously. Infusion of doses up to 80 grams daily for up to 4 months under the supervision of a medical professional have been used with apparent safety (32811,32812,32828,95909,114688,114804). There is insufficient reliable information available about the safety of astragalus when used topically.
PREGNANCY AND LACTATION:
There is insufficient reliable information in humans.
However, astragaloside, a constituent of astragalus, has maternal and fetal toxic effects in animals (32881). Avoid using.
There is insufficient reliable information available about the safety of chaga.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally and appropriately. Standardized ginkgo leaf extracts have been used safely in trials lasting for several weeks up to 6 years (1514,1515,3461,5717,5718,6211,6212,6213,6214,6215)(6216,6222,6223,6224,6225,6490,14383,14499,16634,16635)(16636,16637,17402,17716,17718,87794,87819,87826,87848,87864)(87888,87897,87901,87904,89701,89707,107359,107360). There have been some reports of arrhythmias associated with ginkgo leaf extract. However, it is not yet clear if ginkgo might cause arrhythmia (105253,105254). There is some concern about toxic and carcinogenic effects seen in animals exposed to a ginkgo leaf extract containing 31.2% flavonoids, 15.4% terpenoids, and 10.45 ppm ginkgolic acid, in doses of 100 to 2000 mg/kg five times per week for 2 years (18272). However, the clinical relevance of this data for humans, using typical doses, is unclear. The content of the extract used is not identical to that commonly used in supplement products, and the doses studied are much higher than those typically used by humans. A single dose of 50 mg/kg in rats is estimated to be equivalent to a single dose of about 240 mg in humans (18272).
POSSIBLY SAFE ...when used intravenously, short-term. A standardized ginkgo leaf extract called EGb 761 ONC has been safely administered intravenously for up to 14 days (9871,9872,107360,107452). A Chinese preparation containing ginkgo leaf extract and dipyridamole has been safely administered intravenously for up to 30 days (102881,102882). ...when applied topically, short-term. There was no dermal irritation during a 24-hour patch test using the leaf extract, and no sensitization with repeat applications (112946). When used topically in cosmetics, extracts of ginkgo leaves are reported to be safe, but there is insufficient data to determine the safety of nut and root extracts, and isolated biflavones and terpenoids (112946).
POSSIBLY UNSAFE ...when the roasted seed or crude ginkgo plant is used orally. Consuming more than 10 roasted seeds per day can cause difficulty breathing, weak pulse, seizures, loss of consciousness, and shock (8231,8232). Crude ginkgo plant parts can exceed concentrations of 5 ppm of the toxic ginkgolic acid constituents and can cause severe allergic reactions (5714).
LIKELY UNSAFE ...when the fresh ginkgo seed is used orally. Fresh seeds are toxic and potentially deadly (11296).
PREGNANCY: POSSIBLY UNSAFE
when used orally.
There is concern that ginkgo might have labor-inducing and hormonal effects. There is also concern that the antiplatelet effects of ginkgo could prolong bleeding time if taken around the time of labor and delivery (15052). Theoretically, ginkgo might adversely affect pregnancy outcome; avoid using during pregnancy.
LACTATION:
Insufficient reliable information available; avoid using.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately, short-term (87790,89708).
A specific ginkgo dried extract (Ginko T.D., Tolidaru Pharmaceuticals), has been safely used in doses of 80-120 mg daily for 6 weeks in children aged 6-14 years (17112,95669). Another specific combination product containing ginkgo leaf extract and American ginseng extract (AD-FX, CV Technologies, Canada) has also been safely used in children aged 3-17 years for up to 4 weeks (8235).
CHILDREN: LIKELY UNSAFE
when ginkgo seed is used orally.
The fresh seeds have caused seizures and death in children (8231,11296).
POSSIBLY SAFE ...when used orally, short-term. Holy basil leaf extract has been used with apparent safety at a dose of 500 mg daily for 60-90 days (12242,18107,19575,91571,96944). ...when used topically in the mouth, short-term. Holy basil has been used with apparent safety as a 4% mouthwash solution for up to 30 days (91570,103621).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used in high doses during pregnancy or when trying to conceive.
Animal research suggests that relatively high doses of holy basil extract (200 mg/kg) may reduce implantation rate when used for one week, while long-term use of higher doses (2-4 grams/kg) may decrease the number of full-term pregnancies (55040,91569). There is insufficient reliable information available regarding the safety of holy basil during lactation; avoid using.
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.
POSSIBLY SAFE ...when an extract of reishi mushroom is used orally and appropriately for up to one year (12,5485,70767,70774,70786,70799,70800,70801,70802). ...when whole powdered reishi mushroom is used orally and appropriately for up to 16 weeks (70776,70799,70800,70801,91433,91435,91436,91437,108309).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using
LIKELY SAFE ...when consumed in typical food amounts (6).
POSSIBLY SAFE .... ..when the shiitake mushroom extract AHCC is used orally and appropriately. AHCC 4.5-6 grams daily has been used with apparent safety in clinical trials lasting up to 6 months (22926,30419). Population research identified no safety concerns with the use of AHCC 3 grams daily for up to 9 years (30353,94830).
POSSIBLY UNSAFE ...when shiitake mushroom powder is used orally in medicinal amounts. Ingestion of shiitake mushroom powder 4 grams daily for 10 weeks can cause eosinophilia (1149). ...when uncooked shiitake mushroom is ingested. The lentinan component, which is broken down by heat, can cause toxic reactions, including shiitake dermatitis (94354).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid consuming greater than food amounts.
LIKELY SAFE ...when turkey tail mushroom is used orally and appropriately (5477). ...when polysaccharide krestin (PSK) and polysaccharide peptide (PSP) isolates of turkey tail mushroom are used orally and appropriately (1635,1636,1640,1641,1648,1649,1650,1651,1652,1653,1654) (1655,1656,1657,1658,1659,1660,1661,1662,70167,70168,70171,70188,70200,94076). There is insufficient reliable information available about the safety of turkey tail mushroom when used topically or intravaginally.

Below is general information about the interactions of the known ingredients contained in the product Mushroom Master Blend. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, taking agaricus mushroom with antidiabetes drugs might increase the risk of hypoglycemia.
 Details
In one clinical study in patients with type 2 diabetes who are stabilized on conventional oral hypoglycemic agents, 3 of 29 patients taking an agaricus mushroom extract 500 mg three times daily for 12 weeks reported hypoglycemia, compared to one of 29 patients in the placebo group (15421).
|
Theoretically, taking astragalus with antidiabetes drugs might increase the risk of hypoglycemia.
Details
|
Theoretically, astragalus might interfere with cyclophosphamide therapy.
Details
|
Theoretically, astragalus might interfere with immunosuppressive therapy.
Details
|
Theoretically, astragalus might increase levels and adverse effects of lithium.
Details
Animal research suggests that astragalus has diuretic properties (15103). Theoretically, due to this diuretic effect, astragalus might reduce excretion and increase levels of lithium.
|
Theoretically, chaga may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
In vitro and animal research suggests that chaga extract can inhibit platelet aggregation (26260). This effect has not been reported in humans.
|
Theoretically, taking chaga with antidiabetes drugs might increase the risk of hypoglycemia.
Details
|
Theoretically, chaga might interfere with immunosuppressive therapy.
Details
In vitro research suggests that certain constituents of chaga stimulate immune function (26263). This has not been reported in humans.
|
Theoretically, cordyceps may increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
Details
|
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.
|
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.
|
Theoretically, ginkgo might decrease the levels and clinical effects of alprazolam.
Details
In clinical research, ginkgo extract (Ginkgold) 120 mg twice daily seems to decrease alprazolam levels by about 17%. However, ginkgo does not appear to decrease the elimination half-life of alprazolam. This suggests that ginkgo is more likely to decrease absorption of alprazolam rather than induce hepatic metabolism of alprazolam (11029).
|
Ginkgo has been shown to increase the risk of bleeding in some people when taken with warfarin. Theoretically, ginkgo might increase the risk of bleeding if used with other anticoagulant or antiplatelet drugs.
Details
Several pharmacodynamic studies suggest that ginkgo inhibits platelet aggregation. It is thought that the ginkgo constituent, ginkgolide B, displaces platelet-activating factor (PAF) from its binding sites, decreasing blood coagulation (6048,9760). Several case reports have documented serious bleeding events in patients taking ginkgo (244,578,579,8581,13002,13135,13179,13194,14456,87868). However, population and clinical studies have produced mixed results. Some evidence shows that short-term use of ginkgo leaf does not significantly reduce platelet aggregation and blood clotting (87732). A study in healthy males who took a specific ginkgo leaf extract (EGb 761) 160 mg twice daily for 7 days found no change in prothrombin time (12114). An analysis of a large medical record database suggests that ginkgo increases the risk of a bleeding adverse event by 38% when taken concurrently with warfarin (91326). It has been suggested that ginkgo has to be taken for at least 2-3 weeks to have a significant effect on platelet aggregation (14811). However, a meta-analysis of 18 studies using standardized ginkgo extracts, 80-480 mg daily for up to 32 weeks, did not find a significant effect on platelet aggregation, fibrinogen concentration, or PT/aPTT (17179). In addition, a single dose of ginkgo plus clopidogrel (14811) or ticlopidine does not seem to significantly increase bleeding time or platelet aggregation (17111,87846). Also, taking ginkgo leaf extract daily for 8 days in conjunction with rivaroxaban does not affect anti-factor Xa activity; however, this study did not evaluate bleeding time (109526).
|
Theoretically, ginkgo might reduce the effectiveness of anticonvulsants.
Details
Ginkgo seeds contain ginkgotoxin. Large amounts of ginkgotoxin can cause neurotoxicity and seizure. Ginkgotoxin is present in much larger amounts in ginkgo seeds than leaves (8232). Ginkgo leaf extract contains trace amounts of ginkgotoxin. The amount of ginkgotoxin in ginkgo leaf and leaf extract seems unlikely to cause toxicity (11296). However, there are anecdotal reports of seizure occurring after use of ginkgo leaf both in patients without a history of seizure disorder and in those with previously well-controlled epilepsy (7030,7090).
|
Theoretically, taking ginkgo with antidiabetes drugs might alter the response to antidiabetes drugs.
Details
Ginkgo leaf extract seems to alter insulin secretion and metabolism, and might affect blood glucose levels in people with type 2 diabetes (5719,14448,103574). The effect of ginkgo seems to differ depending on the insulin and treatment status of the patient. In diet-controlled diabetes patients with hyperinsulinemia, taking ginkgo does not seem to significantly affect insulin or blood glucose levels. In patients with hyperinsulinemia who are treated with oral hypoglycemic agents, taking ginkgo seems to decrease insulin levels and increase blood glucose following an oral glucose tolerance test. Researchers speculate that this could be due to ginkgo-enhanced hepatic metabolism of insulin. In patients with pancreatic exhaustion, taking ginkgo seems to stimulate pancreatic beta-cells, resulting in increased insulin and C-peptide levels, but with no significant change in blood glucose levels in response to an oral glucose tolerance test (14448).
|
Theoretically, ginkgo might decrease the levels and clinical effects of atorvastatin.
Details
In humans, intake of ginkgo extract appears to increase atorvastatin clearance, reducing the area under the curve of atorvastatin by 10% to 14% and the maximum concentration by 29%. However, this interaction does not appear to affect cholesterol synthesis and absorption (89706). Further, a model in rats with hyperlipidemia suggests that administering ginkgo extract does not impact blood levels of atorvastatin and leads to lower total cholesterol, low-density lipoprotein cholesterol, and triglycerides when compared with rats given atorvastatin alone (111331).
|
Theoretically, ginkgo might increase levels of drugs metabolized by CYP1A2.
Details
|
Theoretically, ginkgo might decrease levels of drugs metabolized by CYP2C19.
Details
Some clinical research shows that a specific ginkgo leaf extract (Remembrance, Herbs Product LTD) 140 mg twice daily can induce CYP2C19 enzymes and potentially decrease levels of drugs metabolized by these enzymes (13108). However, other clinical research shows that taking ginkgo 120 mg twice daily for 12 days has no effect on levels of drugs metabolized by CYP2C19 (87824).
|
Theoretically, ginkgo might increase levels of drugs metabolized by CYP2C9.
Details
In vitro, a specific standardized extract of ginkgo leaf (EGb 761) inhibits CYP2C9 activity (11026,12061,14337). The terpenoid (ginkgolides) and flavonoid (quercetin, kaempferol, etc.) constituents seem to be responsible for this effect. Most ginkgo extracts contain some amount of these constituents. Therefore, other ginkgo leaf extracts might also inhibit the CYP2C9 enzyme. However, clinical research suggests that ginkgo might not have a significant effect on CYP2C9 in humans. Ginkgo does not seem to significantly affect the pharmacokinetics of CYP2C9 substrates diclofenac or tolbutamide.
|
Theoretically, ginkgo might decrease levels of drugs metabolized by CYP3A4.
Details
There is conflicting evidence about whether ginkgo induces or inhibits CYP3A4 (1303,6423,6450,11026,87800,87805,111330). Ginkgo does not appear to affect hepatic CYP3A4 (11029). However, it is not known if ginkgo affects intestinal CYP3A4. Preliminary clinical research suggests that taking ginkgo does not significantly affect levels of donepezil, lopinavir, or ritonavir, which are all CYP3A4 substrates (11027,87800,93578). Other clinical research also suggests ginkgo does not significantly affect CYP3A4 activity (10847). However, there are two case reports of decreased efavirenz concentrations and increased viral load in patients taking ginkgo. It is suspected that terpenoids from the ginkgo extract reduced drug levels by inducing cytochrome P450 3A4 (CYP3A4) (16821,25464).
|
Theoretically, ginkgo might decrease the levels and clinical effects of efavirenz.
Details
There are two case reports of decreased efavirenz concentrations and increased viral load in patients taking ginkgo. In one case, an HIV-positive male experienced over a 50% decrease in efavirenz levels over the course of 14 months while taking ginkgo extract. HIV-1 RNA copies also increased substantially, from less than 50 to more than 1500. It is suspected that terpenoids from the ginkgo extract reduced drug levels by inducing cytochrome P450 3A4 (CYP3A4) (16821). In another case report, a patient stable on antiviral therapy including efavirenz for 10 years, had an increase in viral load from <50 copies/mL to 1350 copies/mL after 2 months of taking a combination of supplements including ginkgo. After stopping ginkgo, the viral load was again controlled with the same antiviral therapy regimen (25464).
|
Theoretically, ginkgo might increase the risk of bleeding when used with ibuprofen.
Details
Ginkgo might have antiplatelet effects and has been associated with several case reports of spontaneous bleeding. In one case, a 71-year-old male had taken a specific ginkgo extract (Gingium, Biocur) 40 mg twice daily for 2.5 years. About 4 weeks after starting ibuprofen 600 mg daily he experienced a fatal intracerebral hemorrhage (13179). However, the antiplatelet effects of ginkgo have been questioned. A meta-analysis and other studies have not found a significant antiplatelet effect with standardized ginkgo extracts, 80 mg to 480 mg taken daily for up to 32 weeks (17179).
|
Theoretically, taking ginkgo with oral, but not intravenous, nifedipine might increase levels and adverse effects of nifedipine.
Details
Animal research and some clinical evidence suggests that taking ginkgo leaf extract orally in combination with oral nifedipine might increase nifedipine levels and cause increased side effects, such as headaches, dizziness, and hot flushes (87764,87765). However, taking ginkgo orally does not seem to affect the pharmacokinetics of intravenous nifedipine (87765).
|
Theoretically, taking ginkgo with omeprazole might decrease the levels and clinical effects of omeprazole.
Details
Clinical research shows that a specific ginkgo leaf extract (Remembrance, Herbs Product LTD) 140 mg twice daily can induce cytochrome P450 (CYP) 2C19 enzymes and decrease levels of omeprazole by about 27% to 42% (13108).
|
Theoretically, taking ginkgo with P-glycoprotein substrates might increase the levels and adverse effects of these substrates.
Details
A small clinical study in healthy volunteers shows that using ginkgo leaf extract 120 mg orally three times daily for 14 days can increase levels of the P-glycoprotein substrate, talinolol, by 36% in healthy male individuals. However, single doses of ginkgo do not have the same effect (87830).
|
Theoretically, taking ginkgo with risperidone might increase the levels and adverse effects of risperidone.
Details
A single case of priapism has been reported for a 26-year-old male with schizophrenia who used risperidone 3 mg daily along with ginkgo extract 160 mg daily (87796). Risperidone is metabolized by cytochrome P450 (CYP) 2D6 and CYP3A4. CYP3A4 activity might be affected by ginkgo. Theoretically, ginkgo may inhibit the metabolism of risperidone and increase the risk of adverse effects.
|
Theoretically, ginkgo might decrease the levels and clinical effects of rosiglitazone.
Details
Animal research shows that ginkgo leaf extract orally 100 or 200 mg/kg daily for 10 days alters the pharmacodynamics of rosiglitazone in a dose-dependent manner. The 100 mg/kg and 200 mg/kg doses reduce the area under the concentration time curve (AUC) of rosiglitazone by 39% and 52%, respectively, and the half-life by 28% and 39%, respectively. It is hypothesized that these changes may be due to induction of cytochrome P450 2C8 by ginkgo (109525).
|
Theoretically, taking ginkgo with drugs that lower the seizure threshold might increase the risk for convulsions.
Details
Ginkgo seeds contain ginkgotoxin. Large amounts of ginkgotoxin can cause neurotoxicity and seizure. Ginkgotoxin is present in much larger amounts in ginkgo seeds than leaves (8232). Ginkgo leaf extract contains trace amounts of ginkgotoxin. The amount of ginkgotoxin in ginkgo leaf and leaf extract seems unlikely to cause toxicity (11296). However, there are anecdotal reports of seizure occurring after use of ginkgo leaf both in patients without a history of seizure disorder and in those with previously well-controlled epilepsy (7030,7090,14281).
|
Theoretically, ginkgo might decrease the levels and clinical effects of simvastatin.
Details
Clinical research shows that taking ginkgo extract can reduce the area under the curve and maximum concentration of simvastatin by 32% to 39%. However, ginkgo extract does not seem to affect the cholesterol-lowering ability of simvastatin (89704).
|
Theoretically, ginkgo might increase the levels and clinical effects of sofosbuvir.
Details
Animal research in rats shows that giving a ginkgo extract 25 mg/kg orally daily for 14 days increases the area under the concentration time curve (AUC) after a single sofosbuvir dose of 40 mg/kg by 11%, increases the half-life by 60%, and increases the plasma concentration at 4 hours by 38%. This interaction appears to be related to the inhibition of intestinal P-glycoprotein by ginkgo (109524).
|
Theoretically, ginkgo might increase the blood levels of tacrolimus.
Details
In vitro evidence suggests that certain biflavonoids in ginkgo leaves (i.e. amentoflavone, ginkgetin, bilobetin) may inhibit the metabolism of tacrolimus by up to 50%. This interaction appears to be time-dependent and due to inhibition of cytochrome P450 (CYP) 3A4 by these bioflavonoids. In rats given tacrolimus 1 mg/kg orally, amentoflavone was shown to increase the area under the concentration time curve (AUC) of tacrolimus by 3.8-fold (111330).
|
Taking ginkgo with talinolol seems to increase blood levels of talinolol.
Details
There is some evidence that using ginkgo leaf extract 120 mg orally three times daily for 14 days can increase levels of talinolol by 36% in healthy male individuals. However, single doses of ginkgo do not seem to affect talinolol pharmacokinetics (87830).
|
Theoretically, ginkgo might increase the levels and clinical effects of trazodone.
Details
In a case report, an Alzheimer patient taking trazodone 20 mg twice daily and ginkgo leaf extract 80 mg twice daily for four doses became comatose. The coma was reversed by administration of flumazenil (Romazicon). Coma might have been induced by excessive GABA-ergic activity. Ginkgo flavonoids are thought to have GABA-ergic activity and act directly on benzodiazepine receptors. Ginkgo might also increase metabolism of trazodone to active GABA-ergic metabolites, possibly by inducing cytochrome P450 3A4 (CYP3A4) metabolism (6423).
|
Ginkgo has been shown to increase the risk of bleeding in some people when taken with warfarin.
Details
Several pharmacodynamic studies suggest that ginkgo inhibits platelet aggregation. It is thought that the ginkgo constituent, ginkgolide B, displaces platelet-activating factor (PAF) from its binding sites, decreasing blood coagulation (6048,9760). Several case reports have documented serious bleeding events in patients taking ginkgo (244,576,578,579,8581,13002,13135,13179,13194,14456,87868). Information from a medical database suggests that when taken concurrently with warfarin, ginkgo increases the risk of a bleeding adverse event by 38% (91326). There is also some evidence that ginkgo leaf extract can inhibit cytochrome P450 2C9, an enzyme that metabolizes warfarin. This could result in increased warfarin levels (12061). However, population and clinical research has produced mixed results. Clinical research in healthy people suggests that ginkgo has no effect on INR, or the pharmacokinetics or pharmacodynamics of warfarin (12881,15176,87727,87889). A meta-analysis of 18 studies using standardized ginkgo extracts, 80 mg to 480 mg daily for up to 32 weeks, did not find a significant effect on platelet aggregation, fibrinogen concentration, or PT/aPTT (17179). There is also some preliminary clinical research that suggests ginkgo might not significantly increase the effects of warfarin in patients that have a stable INR (11905).
|
Theoretically, holy basil seed oil might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Details
Animal research shows that holy basil seed oil can prolong bleeding time, possibly due to inhibition of platelet aggregation (13251). However, it is not known if this occurs in humans.
|
Theoretically, holy basil might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Details
|
Theoretically, holy basil seed oil might increase the sedative effects of pentobarbital.
Details
|
Theoretically, lion's mane mushroom may increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.
Details
In vitro research suggests that lion's mane mushroom extracts can inhibit platelet aggregation (92619).
|
Theoretically, lion's mane mushroom may have additive effects when used with antidiabetes drugs.
Details
Animal research suggests that an aqueous extract of lion's mane mushroom can reduce serum glucose and increase serum insulin (91996).

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).

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).

Theoretically, the polysaccharide peptide (PSP) component of turkey tail mushroom might increase exposure to cyclophosphamide.
Details
Some animal research shows that the PSP component of turkey tail mushroom can increase the area under the concentration-time curve (AUC) of cyclophosphamide by 44% to 50% and the half-life by 34% to 43% (96569). This interaction could potentially increase the effects and adverse effects of cyclophosphamide. However, it is not known whether PSP affects the levels of the active metabolites of cyclophosphamide that are responsible for its clinical activity.
|
Theoretically, the polysaccharide peptide (PSP) component of turkey tail mushroom might inhibit CYP2C9.
Details
Laboratory research suggests that the PSP component of turkey tail mushroom dose-dependently inhibits CYP2C9 (94075). Theoretically, taking PSP with drugs metabolized by CYP2C9 might increase drug levels and the risk of adverse effects. However, this has not been reported in humans.
|
Theoretically, the polysaccharide peptide (PSP) component of turkey tail mushroom might interfere with the absorption of tamoxifen.
Details
Animal research suggests that PSP increases the time to reach maximum concentration of a single dose of tamoxifen by about 9.5 hours, or 228%. When repeated doses of tamoxifen were given, the time to reach maximum concentration was increased by about 5.6 hours, or 93%. However, PSP did not affect the maximum concentration or the area under the curve of tamoxifen (108308).

Below is general information about the adverse effects of the known ingredients contained in the product Mushroom Master Blend. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, agaricus mushroom is generally well tolerated.
Most Common Adverse Effects:
Orally: Abdominal discomfort, diarrhea, and nausea.
Serious Adverse Effects (Rare):
Orally: Allergic reactions, hepatotoxicity, interstitial lung disease (ILD).
Gastrointestinal ...In one clinical trial, mild gastrointestinal side effects such as nausea, diarrhea, and abdominal discomfort were reported in 6 of 78 patients taking a specific agaricus powder product , Ltd.) 1.8-5.4 grams orally daily for 60 days. The causal relationship between this agaricus mushroom product and the associated gastrointestinal adverse effect was determined to be possible or probable in each case (17185).
Hepatic ...Three cases of severe hepatotoxicity have been reported in females with ovarian or breast cancer receiving chemotherapy who also took agaricus mushroom supplements. Two of the patients had increases in liver function tests a few days after starting agaricus mushroom, which then progressed rapidly to fatal, fulminant hepatitis. One of these patients was also an asymptomatic carrier of hepatitis B virus. In the third case, liver function improved when agaricus mushroom was stopped, worsened when it was restarted, and then recovered fully when the supplement was stopped permanently (16458).
Immunologic ...An allergic reaction has been reported in a female who took a specific agaricus powder product , Ltd.) 1.8 grams daily by mouth for 2 months. The patient developed an urticarial papular rash which resolved when the product was discontinued (17185). Allergic contact cheilitis was also reported in a patient taking a homemade agaricus mushroom extract orally. The reaction resolved upon discontinuation of agaricus mushroom (94720).
Pulmonary/Respiratory ...There is one case report of interstitial lung disease associated with the use of agaricus mushroom for approximately one month in a male with pancreatic ductal adenocarcinoma being treated with gemcitabine. Drug-induced lymphocyte stimulation test (DLST) was positive for agaricus mushroom extract and not gemcitabine. Pneumonitis improved upon discontinuation of agaricus mushroom (108313).
General
...Orally and intravenously, astragalus root seems to be well tolerated.
Topically, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: A case report raises concerns about liver and kidney cysts with astragalus use.
Cardiovascular ...Orally, astragalus has reportedly been associated with lacunar angina in one clinical trial. However, this may not have been caused by astragalus (17355). In addition, rapid intravenous administration of astragalus has resulted in temporary palpitations (32812).
Dermatologic ...Intravenously, astragalus may cause rash, eczema, and pruritus (33034).
Gastrointestinal ...Orally, astragalus has reportedly been associated with enterocolitis and nausea in one clinical trial. However, these effects may not have been caused by astragalus (17355).
Genitourinary ...Orally, astragalus has reportedly been associated with vulvitis in one clinical trial. However, this effect may not have been caused by astragalus (17355).
Hepatic ...A case of high serum CA19-9 levels and small liver and kidney cysts has been reported for a 38-year-old woman who drank astragalus tea daily for one month. Levels returned to normal after one month, and cysts disappeared after ten months. Both symptoms returned following a resumption of astragalus use. The authors state that astragalus was the likely cause given the temporal relationship (90658).
Musculoskeletal ...Orally, astragalus has been associated with reports of musculoskeletal pain in one clinical trial. However, these effects may not have been caused by astragalus (114803).
Neurologic/CNS ...Intravenously, administration of astragalus has been associated with temporary dizziness in patients with heart failure in clinical research (32812,114804). Orally, astragalus has also been associated with dizziness in one clinical study. However, these effects may not have been caused by astragalus (114803).
Pulmonary/Respiratory ...Orally, astragalus has reportedly been associated with rhinosinusitis and pharyngitis in one clinical trial. However, these effects may not have been caused by astragalus (17355).
Renal ...A case of high serum CA19-9 levels and small liver and kidney cysts has been reported for a 38-year-old woman who drank astragalus tea daily for one month. Levels returned to normal after one month, and cysts disappeared after ten months. Both symptoms returned following a resumption of astragalus use. The authors state that astragalus was the likely cause given the temporal relationship (90658).
General ...There is limited reliable information available regarding the adverse effects of chaga.
Renal ...Orally, there have been two cases of kidney failure and one case of acute nephropathy related to excessive chaga consumption, which contains high concentrations of oxalate (96566,105246,108756).
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).
General
...Orally, ginkgo leaf extract is generally well tolerated when used for up to 6 years.
However, the seed and crude plant contain toxic constituents and should be avoided.
Intravenously, ginkgo leaf extract seems to be well tolerated when used for up to 30 days.
Topically, no adverse effects have been reported with ginkgo as a single ingredient. However, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Dizziness, gastrointestinal symptoms, headache.
Serious Adverse Effects (Rare):
Orally: Arrhythmia, bleeding, Stevens-Johnson syndrome.
Cardiovascular
...Cardiac arrhythmias suspected to be related to ginkgo have been reported.
Internationally, there are at least 162 reports from 18 countries, with 34% of cases considered serious, involving five deaths and four life-threatening events. Additionally, a report from Canada found that 10 out of 15 cases of arrhythmia were considered serious. Ginkgo was the only suspect ingredient in 57% of all international reports, with symptoms generally presenting within days of initiation. The most common symptoms included palpitations, tachycardia, bradycardia, syncope, and loss of consciousness. Most cases were reported to be related to oral use of ginkgo leaf products; however, some cases were associated with oral use of the seed, and others with intravenous or intramuscular use of the leaf. Documented discontinuation of ginkgo led to recovery in approximately 84% of cases where ginkgo was the sole suspect. Despite these findings, ginkgo cannot be confirmed as the causal agent. It is possible that these reports are confounded by underlying co-morbidities. Of the reported cases, the main reason for ginkgo use was tinnitus, a symptom commonly associated with pre-existing arrhythmias (105253,105254). Despite this large number of reports, only three cases of cardiac arrhythmia have been published in the literature (105253,105254). In one case, frequent nocturnal episodes of paroxysmal atrial fibrillation were reported for a 35-year-old female taking ginkgo extract 240 mg daily orally for 2 months. Arrythmias ceased following discontinuation of ginkgo (87884).
In one clinical trial, the rate of ischemic stroke and transient ischemic attacks was significantly higher in patients taking ginkgo extract orally when compared with placebo (16635). It is unclear if these events were due to ginkgo, other factors, or a combination.
Dermatologic ...Topically, ginkgo fruit pulp can cause contact dermatitis, with intense itching, edema, papules, and pustules which take 7-10 days to resolve after stopping contact (112946).
Gastrointestinal
...Orally, ginkgo extract may cause mild gastrointestinal discomfort or pain (3965,8543,17112,87818,87858), nausea and vomiting (8543,17112,87728,87844,87858), diarrhea (87844), dry mouth (17112), and constipation (5719,87787).
However, post-market surveillance suggests that the incidence of these events is relatively low, occurring in less than 2% of patients (88007).
Fresh ginkgo seeds can cause stomach ache, nausea, vomiting, or diarrhea. Ingesting roasted seeds in amounts larger than the normal food amounts of 8-10 seeds per day, or long-term, can also cause these same adverse reactions (8231,8232).
Genitourinary ...Orally, ginkgo extract has been reported to cause blood in the urine in one patient (87858).
Hematologic
...Spontaneous bleeding is one of the most concerning potential side effects associated with ginkgo.
There are several published case reports linking ginkgo to episodes of minor to severe bleeding; however, not all case reports clearly establish ginkgo as the cause of bleeding. In most cases, other bleeding risk factors were also present including taking other medications or natural medicines, old age, liver cirrhosis, recent surgery, and other conditions. In most cases, bleeding occurred after several weeks or months of taking ginkgo (13135). Large-scale clinical trials and a meta-analysis evaluating standardized ginkgo leaf extracts show that the incidence of bleeding in patients taking ginkgo is not significantly higher than in those taking placebo (16634,16635,17179,17402).
There are several case reports of intracerebral bleeding. Some of these cases resulted in permanent neurological damage and one case resulted in death (244,578,8581,13135,13179,14456,87868,87977).
There are at least 4 cases of ocular bleeding including spontaneous hyphema (bleeding from the iris into the anterior part of the eye) and retrobulbar hemorrhage associated with ginkgo use (579,10450,13135).
There are also cases of surgical and post-surgical complications in patients using ginkgo. Retrobulbar hemorrhage (bleeding behind the eye) during cataract surgery has been associated with ginkgo use (10450). Excessive postoperative bleeding requiring transfusion has also occurred following laparoscopic surgery in a patient who had been taking ginkgo leaf extract (887). There have also been two cases of excessive bleeding during surgery and post-surgical hematoma in patients undergoing rhytidoplasty and blepharoplasty (13002). In another case, an elderly patient taking ginkgo experienced excessive postoperative bleeding following total hip arthroplasty (13194). In another case, use of ginkgo following liver transplantation surgery was associated with subphrenic hematoma requiring evacuation by laparotomy. The patient also subsequently experienced vitreous hemorrhage (14315). In another case, an elderly patient who had taken ginkgo chronically experienced excessive post-operative bleeding following an ambulatory surgical procedure (14453).
In another case, an elderly man experienced nose bleeds and ecchymosis following use of ginkgo. One case of diffuse alveolar hemorrhage in a female taking ginkgo and ginseng for over one year has been reported (95670). These instances of bleeding stopped when ginkgo was discontinued, and recurred when the patient started taking ginkgo again (13135).
Persistent bleeding has also occurred following dental surgery (87862) and laparoscopic cholecystectomy (88000). Nosebleed has also been reported as an adverse effect in a clinical trial (87813).
Immunologic ...Orally, ginkgo leaf extract can cause allergic skin reactions in some patients (14449,15578,112946). In one case, a patient developed acute generalized exanthematous pustulosis 48 hours after taking a single-ingredient ginkgo product. The rash resolved within 10 days after discontinuing ginkgo (14449). In another case, progressive erythema of the face, neck, trunk, and extremities occurred after two 60 mg oral doses of ginkgo extract (112946). There is also a case of Stevens-Johnson syndrome following a second administration of a preparation containing ginkgo leaf extract, choline, vitamin B6, and vitamin B12 (208). In another case, systemic edema and severe arthralgia was reported after contact with a ginkgo tree nut and manifested as multifocal lymphadenopathy associated with an allergic reaction on PET/CT scan imaging (95672).
Musculoskeletal ...Edema has been reported for three patients treated with ginkgo extract 40 mg orally three times daily (87818).
Neurologic/CNS ...Orally, ginkgo extract may cause headache (6220,8543,87818), dizziness (5719,87818), increased desire to sleep (87839), and sedation (10893) in some patients. In addition, although ginkgo leaf and ginkgo leaf extract contain only small amounts of ginkgotoxin, there are anecdotal reports of seizure occurring after use of ginkgo leaf preparations both in patients without a history of seizure disorder and in those with previously well-controlled epilepsy (7030,7090,11296,14281).
Ocular/Otic
...Orally, ginkgo extract may cause tinnitus is some patients, although the incidence is rare (8543).
Topically, eye drops containing ginkgo extract and hyaluronic acid may cause stinging sensations in some people (87829).
Psychiatric ...Orally, ginkgo has been associated with a single case of mood dysregulation. A 50-year-old female with schizophrenia developed irritability, difficulty controlling anger, and agitation after one week of taking ginkgo 80 mg twice daily. The mood changes resolved within 2-3 days of discontinuation. When ginkgo was re-trialed at a later date, the same symptoms reappeared, and again dissipated after discontinuation of the ginkgo product. The relationship between ginkgo and mood dysregulation was considered to be "probable" based on the Naranjo adverse drug reaction probability scale (96763); however, the exact mechanism by which ginkgo may have affected mood regulation is unknown.
General
...Orally and topically, holy basil extract seems to be well tolerated.
Most Common Adverse Effects:
Orally: Loose stools and nausea.
Topically: Bitter taste with oral application.
Gastrointestinal
...Orally, two out of 24 participants taking capsules containing holy basil extract in one clinical study experienced nausea or loose stools (55037).
Topically, holy basil mouthwash has been reported to cause a bitter taste in clinical trials (55038).
General
...Orally, lion's mane mushroom is generally well tolerated.
Most Common Adverse Effects:
Orally: Gastrointestinal discomfort, nausea, skin rash.
Dermatologic ...Orally, lion's mane mushroom may cause skin rash (105546).
Gastrointestinal ...Orally, lion's mane mushroom may cause gastrointestinal discomfort and nausea (91999,105546).
General
...Orally, maitake mushroom is generally well tolerated.
Most Common Adverse Effects:
Orally: Gastrointestinal effects, including diarrhea and epigastric pain.
Dermatologic ...In a clinical trial, one patient experienced rash and pruritus after two doses of maitake mushroom polysaccharide extract. The allergic reaction cleared without intervention (61239).
Gastrointestinal ...In clinical research of a polysaccharide extract from maitake mushroom, one patient reported nausea (61239) and 2 out of 26 reported epigastric pain (17131). In a clinical trial of a liquid extract from maitake mushroom, 2 out of 21 patients experienced diarrhea, and one experienced nausea. One patient withdrew from the study due to diarrhea (92843).
Immunologic ...In a clinical trial of a liquid extract from maitake mushroom, 4 out of 21 patients experienced eosinophilia (92843).
Musculoskeletal ...In a clinical trial of a polysaccharide extract from maitake mushroom, one patient reported joint swelling (61239).
Pulmonary/Respiratory ...There is one case of occupational hypersensitivity pneumonitis (HP) caused by maitake mushroom spores (61228).
General
...Orally, reishi mushroom is generally well tolerated.
Most Common Adverse Effects:
Orally: Dizziness, dry mouth, itching, nausea, rash, and stomach upset.
Dermatologic ...Orally, reishi mushroom can cause itching, rash, and other skin reactions (12,5479).
Gastrointestinal ...Orally, reishi mushroom can cause dryness of the mouth, throat, or nasal cavity, nausea, stomach upset, and, more rarely, diarrhea (12,70779,91438,108309).
Hematologic ...Orally, reishi mushroom can cause nosebleed and bloody stools (12,91438).
Hepatic ...One case of hepatotoxicity and one case of fatal fulminant hepatitis have been reported in patients who had used reishi mushroom powder for 1-2 months (70766). There is a case report of a 61-year-old male with hypereosinophilia associated with hepatic nodules following the use of reishi mushroom powder for about 2 months. Symptoms resolved after discontinuation of the product. Although these side effects were thought to be associated with the use of reishi mushroom powder, it is unclear if other factors played a role. The patient had been taking tegafur, gimeracil, and oteracil potassium for about 4 months following anterior resection for rectal adenocarcinoma but discontinued these agents and initiated reishi mushroom due to liver injury (108312).
Neurologic/CNS ...Orally, reishi mushroom can cause dizziness (91438). Other rare symptoms include insomnia and headache (70776,70779).
Pulmonary/Respiratory ...Respiratory allergy to reishi spores can occur (12,5479). Sore throat and runny nose have also been reported (70776,91438).
General
...Orally, shiitake mushroom is generally well tolerated when cooked and consumed as a food.
Most Common Adverse Effects:
Orally: Abdominal discomfort, bloating, diarrhea, nausea, and vomiting.
Serious Adverse Effects (Rare):
Orally: Consumption of raw shiitake mushroom can cause shiitake dermatitis, a skin eruption resembling whiplash marks which can be accompanied by systemic symptoms. Large pieces that have been inadequately chewed can cause intestinal blockage, occasionally requiring surgery.
Dermatologic
...Orally, shiitake mushrooms can cause shiitake dermatitis, a skin eruption that resembles whiplash marks, usually found on the trunk and limbs.
This dermatitis is thought to be a toxic response to lentinan or other compounds found normally in uncooked or inadequately cooked shiitake mushroom. The rash can be made worse by scratching. Symptom onset is usually within hours to days and can persist for 3-4 weeks before resolving on its own. There is some evidence that treatment with steroids alone or with antihistamines might reduce the duration of the rash by a small amount in some people (1148,1152,74782,74806,94236,94237,94238,94240,94241,94243) (94244,94246,94247,94248,94249,94252,94253,94254,94255,94256)(94257,94259,94261,94262,108302,111909,111912,111913). The dermatitis may include small purple spots from broken capillaries, skin plaques, burning, blanching, and pustules (94256,108302). Rarely the rash may look like measles rather than whiplash (94256). Histologically, there may be evidence of dermal and epidermal edema, lymphocyte infiltration, and skin thickening (94256,94257). Other symptoms associated with the dermatitis include fever, aching, malaise, eosinophilia, diarrhea, prickling in the hands, trouble swallowing, conjunctivitis, and pustules with small ulcers in the mouth (94240,94246,94247,94249,94256,94257,108302). It is likely that the dermatitis and other symptoms are due to a delayed type hypersensitivity reaction (94244,94255). Cooking shiitake mushroom generally prevents shiitake dermatitis, although some cases have occurred in people who have consumed cooked sources (94242,94244). It appears that to inactivate lentinan, cooking temperatures of at least 130°C are needed (94243).
Less common is a photosensitivity reaction associated with oral ingestion, which involves rash and pruritus after sun exposure (1148,94241).
Orally, the shiitake mushroom extract AHCC has been reported to cause mild itching (30375).
Gastrointestinal
...Orally, shiitake mushrooms can cause abdominal discomfort, including bloating, nausea, pain, vomiting, and diarrhea (1149,30365,30375,30419,94241).
Gastrointestinal symptoms, such as diarrhea, problems swallowing, or mouth ulcers have been associated with shiitake dermatitis (94241,94256). Consumption of large pieces of shiitake mushroom with inadequate chewing can cause abdominal obstruction that has resulted in death in one case and surgical intervention in two others. In another case, parenteral nutrition was used exclusively until the shiitake mushroom pieces were passed (1147,94260,103160,108303,108304).
Topically, an oral rinse containing shiitake mushroom extract has been associated with teeth sensitivity, teeth staining, and burning in the mouth (94250).
Hematologic ...Ingestion of shiitake mushroom powder 4 grams daily for 10 weeks caused eosinophilia in 5 of 10 healthy humans (1149). Eosinophilia, and leukocytosis or leukopenia have been reported with shiitake dermatitis (94254,94256,94257).
Immunologic ...Allergic contact dermatitis can occur by contact with shiitake hyphae (filaments) (1153,74785,111913). It appears to be more common in growers or others that handle shiitake mushrooms extensively (94241,94259). Contact or inhalation also results in other symptoms of allergy, such as asthma, rhinitis, conjunctivitis, and pneumonia (94241,94249,94258,94259).
Musculoskeletal ...Orally, the shiitake mushroom extract AHCC has been reported to cause foot cramps and difficulty moving hand joints (30365,30416).
Neurologic/CNS
...In patients experiencing shiitake dermatitis, other symptoms may include prickling in the hands (94256).
Malaise has also been reported following oral intake or contact (1151,94240).
Orally, the shiitake mushroom extract AHCC has been reported to cause mild and transient headache (30365).
Ocular/Otic ...Conjunctivitis has been reported rarely in mushroom growers and handlers, or following oral intake in patients with shiitake dermatitis (94241,94256,94259).
Pulmonary/Respiratory ...In mushroom workers, hypersensitivity pneumonitis due to shiitake spore inhalation has occurred. Symptoms include difficulty breathing, chest pain, a dry cough, asthma, and rhinitis (1150,1151,74776,74813,94239,94241,94258,94259).
General ...Orally, turkey tail mushroom and its PSK component are generally well tolerated. There have been reports of gastrointestinal side effects, hematological abnormalities, liver dysfunction, and palpitations, but these are in patients who received PSK in addition to standard chemotherapy. It is not known if these are due to PSK, the chemotherapy, or both.
Cardiovascular ...Palpitations have occurred when PSK is taken with standard chemotherapy for cancer (1657). It is not clear if this is due to PSK, the chemotherapy, or both.
Dermatologic
...Pigmentation of the nails and erythema have occurred when PSK is taken with standard chemotherapy (1657,1660,70175,94076).
It is not clear if this is due to PSK, the chemotherapy, or both.
Intravaginally, a specific gel (Papilocare, Procare Health) containing turkey tail mushroom with neem, carboxymethyl-beta-glucan, hyaluronic acid, gotu kola, aloe, and alpha-glucan oligosaccharide has been reported to cause vulvovaginal stinging, burning, itching, and candidiasis (108305,111904). The specific role of turkey tail mushroom is unclear.
Gastrointestinal ...Nausea, vomiting, appetite loss, stomach discomfort, diarrhea, constipation, and gastric ulcer have occurred when PSK is taken with standard chemotherapy for cancer (1651,1657,70175,70201,94076). However, one study reported a decreased incidence of gastrointestinal side effects when PSK was taken with chemotherapy (70188,70197).
Hematologic ...Leukopenia, thrombocytopenia, and albuminuria have occurred when PSK is taken with standard chemotherapy (1651,1657,70175,70201,94076). It is not clear if this is due to PSK, the chemotherapy, or both.
Hepatic ...Elevated liver enzymes, liver function impairment, and hepatotoxicity have occurred when PSK is taken with standard chemotherapy (1651,1657,70175,70201,94076). It is not clear if this is due to PSK, the chemotherapy, or both.
Musculoskeletal ...Malaise and fatigue have occurred when PSK is taken with standard chemotherapy (1657,1660,70175,94076). It is not clear if this is due to PSK, the chemotherapy, or both.
Pulmonary/Respiratory ...Coughing has occurred when PSK is taken with standard chemotherapy (1657,1660,70175,94076). It is not clear if this is due to PSK, the chemotherapy, or both.
