What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 8 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1,920 mg) without saying how much of each component you get.

Mycozil contains 8 active ingredients in a proprietary blend. Licorice, anise, and pau d'arco are herbal extracts; fulvic acid is a compound derived from organic material.

Beta-Glucanase and Hemicellulase are enzymes meant to break down cell wall material. Brevibacillus laterosporus is a probiotic-type organism.

The product also contains inactive ingredients — organic gum acacia and a vegetable capsule — that serve as a binder and capsule material. The proprietary blend format means the exact amount of each active ingredient isn't listed separately on the label.

This makes it harder to know the dose of licorice, anise, fulvic acid, or pau d'arco you're actually taking — important when considering interactions or side effects.

Does it work?

Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: support systemic cleansing and candida levels.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence we hold shows that licorice is possibly effective for canker sores and atopic dermatitis (eczema). For anise, fulvic acid, and pau d'arco — the other active ingredients — we have insufficient evidence to rate their effectiveness for any condition.

Licorice has also been studied for Addison disease and asthma, but the evidence is too thin to say whether it helps. Because the ingredients are in a proprietary blend and we don't have their individual amounts, we can't tell you the product's strength for any of these uses.

The evidence, ingredient by ingredient Licorice Fulvic Acid Anise Pau D'arco

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Licorice is generally well tolerated in food amounts, but high doses or long-term use of its active component glycyrrhizin can cause serious problems — including electrolyte imbalances, high blood pressure, and low potassium. The most common side effects from licorice are headache, nausea, and vomiting.

Rare serious effects include pseudoaldosteronism (a condition mimicking hormonal disorders). Licorice is unsafe in pregnancy and should be avoided while breastfeeding due to insufficient safety data.

Fulvic acid appears well tolerated in the short term, though human safety data is limited. Common side effects are diarrhea, headache, and sore throat.

Avoid it in pregnancy and while breastfeeding due to lack of safety information. Anise is likely safe during pregnancy and breastfeeding, but medicinal amounts and essential oil should be avoided in pregnancy.

Anise may trigger allergic reactions including contact dermatitis, asthma, or in sensitive people, anaphylaxis. Pau d'arco may cause anemia and bleeding at higher doses (above 1.5 grams lapachol daily), and can trigger nausea, vomiting, or diarrhea.

It is possibly unsafe in pregnancy and should be avoided while breastfeeding.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 4 of the 4 matched ingredients can interact with medications — Anise, Pau D'arco, Licorice, Fulvic Acid.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; heart-rhythm medications.
  • For scale: 1,265 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking Mycozil, check with your doctor or pharmacist if you take heart medications (especially digoxin), blood thinners or antiplatelet drugs (warfarin, aspirin, others), diabetes medications, cancer chemotherapy (cisplatin, paclitaxel), thyroid hormone, antidepressants (fluoxetine, imipramine), sedatives (diazepam, midazolam), immunosuppressants, birth control or hormone therapy, loop diuretics (water pills), or caffeine. All are documented to interact with one or more of this product's ingredients.

organic Licorice18 drug types · 1,040 drugs

Antihypertensive Drugs

Theoretically, licorice might reduce the effects of antihypertensive drugs.
In human research, licorice increases blood pressure in a dose-dependent manner.

Likelihood Possible Evidence B
Cisplatin (Platinol-Aq)

Theoretically, licorice might reduce the effects of cisplatin.
In animal research, licorice diminished the therapeutic efficacy of cisplatin.

Likelihood Possible Evidence D
Corticosteroids

Theoretically, concomitant use of licorice and corticosteroids might increase the side effects of corticosteroids.
Case reports suggest that concomitant use of licorice and oral corticosteroids, such as hydrocortisone, can potentiate the duration of activity and increase blood levels of corticosteroids. Additionally, in one case report, a patient with neurogenic orthostatic hypertension stabilized on fludrocortisone 0.1 mg twice daily developed pseudohyperaldosteronism after recent consumption of large amounts of black licorice.

Likelihood Possible Evidence D
Cytochrome P450 2B6 (Cyp2B6) Substrates

Theoretically, licorice might increase levels of drugs metabolized by CYP2B6.
In vitro research shows that licorice extract and glabridin, a licorice constituent, inhibit CYP2B6 isoenzymes. Licorice extract from the species G. uralensis seems to inhibit CYP2B6 isoenzymes to a greater degree than G. glabra extract in vitro. Theoretically, these species of licorice might increase levels of drugs metabolized by CYP2B6; however, these interactions have not yet been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, licorice might increase levels of drugs metabolized by CYP2C19.
In vitro, licorice extracts from the species G. glabra and G. uralensis inhibit CYP2C19 isoenzymes in vitro. Theoretically, these species of licorice might increase levels of drugs metabolized by CYP2C19; however, this interaction has not yet been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C8 (Cyp2C8) Substrates

Theoretically, licorice might increase levels of drugs metabolized by CYP2C8.
In vitro, licorice extract from the species G. glabra and G. uralensis inhibits CYP2C8 isoenzymes. Theoretically, these species of licorice might increase levels of drugs metabolized by CYP2C8; however, this interaction has not yet been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, licorice might increase or decrease levels of drugs metabolized by CYP2C9.
There is conflicting evidence about the effect of licorice on CYP2C9 enzyme activity. In vitro research shows that extracts from the licorice species G. glabra and G. uralensis moderately inhibit CYP2C9 isoenzymes. However, evidence from an animal model shows that licorice extract from the species G. uralensis can induce hepatic CYP2C9 activity. Until more is known, licorice should be used cautiously in people taking CYP2C9 substrates.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, licorice might increase or decrease levels of drugs metabolized by CYP3A4.
Pharmacokinetic research shows that the licorice constituent glycyrrhizin, taken in a dosage of 150 mg orally twice daily for 14 days, modestly decreases the area under the concentration-time curve of midazolam by about 20%. Midazolam is a substrate of CYP3A4, suggesting that glycyrrhizin modestly induces CYP3A4 activity. Animal research also shows that licorice extract from the species G. uralensis induces CYP3A4 activity. However, licorice extract from G. glabra species appear to inhibit CYP3A4-induced metabolism of testosterone in vitro. It is thought that the G. glabra inhibits CYP3A4 due to its constituent glabridin, which is a moderate CYP3A4 inhibitor in vitro and not present in other licorice species. Until more is known, licorice should be used cautiously in people taking CYP3A4 substrates.

Likelihood Possible Evidence B
Digoxin (Lanoxin)

Theoretically, concomitant use of licorice with digoxin might increase the risk of cardiac toxicity.
Overuse or misuse of licorice with cardiac glycoside therapy might increase the risk of cardiac toxicity due to potassium loss.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, concomitant use of licorice with diuretic drugs might increase the risk of hypokalemia.
Overuse of licorice might compound diuretic-induced potassium loss. In one case report, a 72-year-old male with a past medical history of hypertension, type 2 diabetes, hyperlipidemia, arrhythmia, stroke, and hepatic dysfunction was hospitalized with severe hypokalemia and uncontrolled hypertension due to pseudohyperaldosteronism. This was thought to be provoked by concomitant daily consumption of a product containing 225 mg of glycyrrhizin, a constituent of licorice, and hydrochlorothiazide 12.5 mg for 1 month.

Likelihood Possible Evidence D
Estrogens

Theoretically, licorice might increase or decrease the effects of estrogen therapy.
Theoretically, licorice might interfere with estrogen therapy due to estrogenic and anti-estrogenic effects.

Likelihood Possible Evidence D
Loop Diuretics

Theoretically, loop diuretics might increase the mineralocorticoid effects of licorice.
Theoretically, loop diuretics might enhance the mineralocorticoid effects of licorice by inhibiting the enzyme that converts cortisol to cortisone; however, bumetanide (Bumex) does not appear to have this effect.

Likelihood Possible Evidence D
Midazolam (Versed)

Theoretically, licorice might decrease levels of midazolam.
In humans, the licorice constituent glycyrrhizin appears to moderately induce the metabolism of midazolam. This is likely due to induction of cytochrome P450 3A4 by licorice. Until more is known, licorice should be used cautiously in people taking midazolam.

Likelihood Possible Evidence B
P-Glycoprotein Substrates

Theoretically, licorice might decrease the absorption of P-glycoprotein substrates.
In vitro research shows that licorice can increase P-glycoprotein activity.

Likelihood Possible Evidence D
Paclitaxel (Abraxane, Onxol)

Theoretically, licorice might decrease plasma levels and clinical effects of paclitaxel.
Multiple doses of licorice taken concomitantly with paclitaxel might reduce the effectiveness of paclitaxel. Animal research shows that licorice 3 grams/kg given orally for 14 days before intravenous administration of paclitaxel decreases the exposure to paclitaxel and increases its clearance. Theoretically, this occurs because licorice induces cytochrome P450 3A4 enzymes, which metabolize paclitaxel. Notably, a single dose of licorice did not affect exposure or clearance of paclitaxel.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, licorice might decrease plasma levels and clinical effects of warfarin.
Licorice seems to increase metabolism and decrease levels of warfarin in animal models. This is likely due to induction of cytochrome P450 2C9 (CYP2C9) metabolism by licorice. Advise patients taking warfarin to avoid taking licorice.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, licorice might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that licorice induces CYP1A2 enzymes.

Likelihood Possible Evidence D
Methotrexate (Trexall, Others)

Theoretically, licorice might increase levels of methotrexate.
Animal research suggests that intravenous administration of glycyrrhizin, a licorice constituent, and high-dose methotrexate may delay methotrexate excretion and increase systemic exposure, leading to transient elevations in liver enzymes and total bilirubin. This interaction has not yet been reported in humans.

Likelihood Unlikely Evidence D

Fulvic Acid3 drug types · 257 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, taking fulvic acid may decrease the effectiveness of anticoagulant and antiplatelet drugs.
In vitro evidence shows that fulvic acid, formed from the oxidation and polymerization of protocatechuic acid, can shorten prothrombin time in human plasma, increasing the risk of clot formation.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, taking fulvic acid might decrease the effects of immunosuppressive therapy.
Animal research shows that fulvic acid stimulates immune function.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, taking fulvic acid with thyroid hormone therapy might interfere with the ability to normalize thyroid function.
Animal research shows that fulvic acid increases the plasma level of thyroid-stimulating hormone (TSH) and decreases the thyroxine (T4):triiodothyronine (T3) ratio.

Likelihood Possible Evidence D
Fulvic Acid full monograph & interactions

organic Anise11 drug types · 245 drugs

Antidiabetes Drugs

Theoretically, anise seed might increase the risk of hypoglycemia when taken with antidiabetes drugs.
A small clinical study shows that anise seed powder decreases fasting blood glucose levels by 36% when compared to baseline.

Likelihood Possible Evidence B
Caffeine

Theoretically, anise oil might decrease the efficacy of caffeine.
Animal research shows that taking anise oil with caffeine decreases the bioavailability of caffeine. Whether this interaction will occur in humans is unclear.

Likelihood Possible Evidence D
Codeine

Theoretically, anise oil might increase the effects and adverse effects of codeine.
Animal research shows that anise oil increases the analgesic effects of codeine, possibly by inducing its phase I metabolism and increasing conversion to morphine. Whether this interaction occurs in humans is unclear.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, anise might interfere with contraceptive drug therapy.
Some in vitro research suggests that anise has estrogenic effects, while other in vitro research suggests that anise has antiestrogenic effects.

Likelihood Possible Evidence D
Diazepam (Valium)

Theoretically, anise oil might increase the effects and adverse effects of diazepam.
Animal research shows that taking anise oil with diazepam increases the motor impairment associated with diazepam, possibly by inhibiting its breakdown by cytochrome P450 3A4. Whether this interaction occurs in humans is unclear.

Likelihood Possible Evidence D
Estrogens

Theoretically, anise might interfere with estrogen-based hormone replacement therapy.
Some in vitro research suggests that anise has estrogenic effects, while other in vitro research suggests that anise has antiestrogenic effects.

Likelihood Possible Evidence D
Fluoxetine (Prozac)

Theoretically, anise oil might decrease the efficacy of fluoxetine.
Animal research shows that taking anise oil with fluoxetine reduces the antidepressant effects of fluoxetine, possibly by promoting its breakdown by cytochrome P450 2D6. Whether this interaction occurs in humans is unclear.

Likelihood Possible Evidence D
Imipramine (Tofranil)

Theoretically, anise oil might decrease the efficacy of imipramine.
Animal research shows that taking anise oil with imipramine reduces the antidepressant effects of imipramine, possibly by promoting its breakdown by cytochrome P450 2D6. Whether this interaction occurs in humans is unclear.

Likelihood Possible Evidence D
Midazolam (Versed)

Theoretically, anise oil might increase the effects and adverse effects of midazolam.
Animal research shows that taking anise oil with midazolam increases the motor impairment associated with midazolam, possibly by inhibiting its breakdown by cytochrome P450 3A4. Whether this interaction occurs in humans is unclear.

Likelihood Possible Evidence D
Tamoxifen (Nolvadex)

Theoretically, anise might interfere with tamoxifen therapy.
Some in vitro research suggests that anise has estrogenic effects, while other in vitro research suggests that anise has antiestrogenic effects.

Likelihood Possible Evidence D
Acetaminophen (Tylenol, Others)

Theoretically, anise oil might decrease the levels and clinical effects of acetaminophen.
Animal research shows that taking anise oil with acetaminophen decreases peak plasma levels of acetaminophen but does not reduce overall bioavailability. Whether this interaction will occur in humans is unclear.

Likelihood Possible Evidence D

wildcrafted Pau d'Arco1 drug type · 122 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, pau d'arco might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro research shows that pau d'arco reduces platelet aggregation and may interfere with vitamin K. One clinical study shows that taking the lapachol constituent of pau d'arco in doses above 1.5 grams daily increases the risk of bleeding. The effects of whole pau d'arco or pau d'arco extract in humans are unclear.

Mycozil by Global Healing: Common Questions

Does Mycozil by Global Healing interact with any medications?
Yes. Based on its ingredients, Mycozil has a known interaction with 1,264 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Mycozil contains 8 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take Mycozil if I'm pregnant or breastfeeding?
Licorice is unsafe in pregnancy and should be avoided while breastfeeding. Fulvic acid and pau d'arco also lack safety data for pregnancy and breastfeeding, so they should be avoided during both. Anise is likely safe during pregnancy and lactation, but not medicinal amounts of it. Because this product contains ingredients rated unsafe or possibly unsafe in pregnancy and lactation, talk with your doctor or midwife before taking it if you're pregnant or nursing.
What are the most common side effects of Mycozil?
The most common side effects reported for licorice are headache, nausea, and vomiting. Fulvic acid may cause diarrhea, headache, and sore throat. Anise is generally well tolerated but can cause contact dermatitis if applied to skin. Pau d'arco at high doses may cause nausea, vomiting, and diarrhea.
Does Mycozil work for yeast or fungal infections?
We don't hold effectiveness data in our monographs for this product's use against yeast or fungal infections. The evidence we have covers licorice for canker sores and eczema only, and anise, fulvic acid, and pau d'arco for other conditions where evidence is too thin to rate. If you're considering it for a specific infection, ask your doctor or pharmacist whether the science supports its use.
Can I take Mycozil long-term?
Licorice can cause serious side effects with high doses or prolonged use, so long-term use needs careful medical supervision. Fulvic acid and pau d'arco have limited human safety data beyond short-term use. Talk with your doctor about how long it's safe to take this product.
What's in Mycozil?
It has 8 active ingredients: licorice, fulvic acid, anise, pau d'arco, two enzymes (Beta-Glucanase and Hemicellulase), Brevibacillus laterosporus, and Jatoba. The exact amounts of each are proprietary — not listed individually on the label — so you can't tell the strength of any single ingredient.
Why can't you check Beta-Glucanase, Hemicellulase, Jatoba, and Brevibacillus laterosporus for interactions?
We hold no data for these four ingredients in our monograph database, so we cannot say whether they interact with medications. If you're concerned about any of them, ask your pharmacist or doctor to research them for you.
