HelloPharmacist Scorecard of Maitake Alcohol Free by Herbal Terra

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: maitake mushroom extract in dry form. Maitake is a medicinal mushroom traditionally used in herbal medicine.

The supplement also contains glycerin and water as inactive ingredients (the carrier and preservative).

Does it work?

Couldn't assess
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

This is a single-ingredient Maitake Mushroom product and its label doesn't state a use — see Maitake Mushroom's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for maitake mushroom isn't yet established for the conditions studied so far. The data we hold shows insufficient reliable evidence to rate its use for allergic rhinitis (hay fever), chemotherapy-induced anemia, laryngeal cancer, and chemotherapy-induced diarrhea.

That doesn't mean it won't work — it means we don't have enough solid clinical research yet to say either way.

The evidence, ingredient by ingredient Maitake Mushroom

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Maitake mushroom is generally well tolerated when taken as a supplement, though it hasn't been fully studied. The most common side effects are stomach-related: diarrhea and epigastric pain (upper belly discomfort).

In clinical trials, a small number of participants experienced nausea, and one person reported a rash and itching that went away on its own. Because there isn't enough safety data, concentrated maitake supplements are not advised during pregnancy or while breastfeeding.

If you're pregnant or nursing, talk with your doctor or pharmacist before using this product.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

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

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Maitake Mushroom.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 260 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.

Check with your pharmacist if you take warfarin (Coumadin) — there's evidence maitake may boost its blood-thinning effects. Also flag any blood pressure medications or diabetes drugs before starting, since maitake can lower both on its own.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Maitake mushroom is a reasonable choice if you're looking to explore traditional medicinal mushrooms, but it's not for everyone. If you take warfarin, blood pressure medications, or diabetes drugs, you'll need to check with your pharmacist first — the interactions are real.

Stick with your pharmacist if you're pregnant, nursing, or unsure whether it fits your health picture.

Maitake Mushroom Extract, Dry3 drug types · 260 drugs

Antidiabetes Drugs

Theoretically, combining maitake mushroom with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research shows that taking maitake mushroom polysaccharide (MMP) can lower blood glucose levels in patients with types 2 diabetes.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, combining maitake mushroom with antihypertensive drugs might increase the risk of hypotension.
Animal research shows that maitake mushroom can lower blood pressure.

Likelihood Possible Evidence D
Warfarin (Coumadin)

There is limited evidence that maitake mushroom may increase the anticoagulant effects of warfarin.
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.

Maitake Alcohol Free by Herbal Terra: Common Questions

Does Maitake Alcohol Free by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Maitake Alcohol Free has a known interaction with 260 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Maitake Alcohol Free contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 this if I'm on warfarin?
Not without checking with your pharmacist first. There's evidence that maitake can increase warfarin's blood-thinning effects, which could be risky. One person's blood-thinning level shot up after taking maitake. Your pharmacist can review your dose and monitor you if needed.
What are the side effects?
Most people tolerate it well, but stomach upset is the main concern — diarrhea and upper belly pain are the most common. A few trial participants also reported nausea. One person developed a rash and itching that cleared on its own.
Is it safe during pregnancy or breastfeeding?
There isn't enough safety data to know either way, so concentrated supplements like this one are not advised. Talk with your doctor or pharmacist about whether it's okay for your situation.
Does maitake actually work?
The evidence isn't settled yet. The studies we have don't give us enough reliable data to say whether it helps with hay fever, cancer-related side effects, or other conditions it's used for. You might benefit, but we can't promise it based on current research.
Will this lower my blood sugar or blood pressure?
Maitake can lower both on its own, which is why it can interact with diabetes and blood pressure medications. If you take either type of drug, your pharmacist needs to know before you start this.
What's actually in this bottle?
It's maitake mushroom extract (the active ingredient) mixed with glycerin and water. No alcohol, despite the name — the glycerin is the carrier. It's a liquid you can take by mouth.
