HelloPharmacist Scorecard of Hou Tou Gu 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: Hou Tou Gu, a dried mushroom liquid extract of Hericium erinaceus, commonly known as lion's mane mushroom. The only other ingredient listed is menstruum, which is the liquid used to extract the mushroom's active compounds.

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 Lion's Mane Mushroom product and its label doesn't state a use — see Lion's Mane 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 on lion's mane mushroom isn't established in our data. We don't have reliable evidence to rate it for Alzheimer disease, anxiety, athletic performance, cancer, cognitive function, or cognitive impairment.

That doesn't mean it doesn't work — it means we don't yet have strong enough research to say either way. If you're considering it for a specific purpose, that's a good question to bring to your doctor or pharmacist.

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 0 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.

Lion's mane mushroom is generally well tolerated when used as a food, but long-term safety as a supplement hasn't been well studied. The most commonly reported side effects are gastrointestinal discomfort, nausea, and skin rash.

There isn't enough safety data to use this product during pregnancy or while breastfeeding. If you're pregnant, planning to become pregnant, or nursing, talk with your doctor or pharmacist about whether this product is right for you.

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 — Lion's Mane Mushroom.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 327 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 this product, double-check your medications if you're on blood thinners or antiplatelet drugs (like warfarin or aspirin) — lion's mane may increase bleeding risk. Also flag it with your doctor if you take diabetes medications or immunosuppressants, since the mushroom may add to their effects or interfere with their work.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

Lion's mane mushroom is generally well tolerated, but it can interact with blood thinners, diabetes medications, and immunosuppressants — all Moderate-severity concerns. If you take any of those medication types, check your specific drugs with the tool on this page before starting.

Anyone pregnant, breastfeeding, or on long-term medications should talk it over with their own pharmacist or doctor first.

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.
What is Hou Tou Gu?
Hou Tou Gu is the Chinese name for lion's mane mushroom (Hericium erinaceus). This product is a liquid extract of the dried mushroom, made without alcohol.
Can I take this if I'm on a blood thinner?

Does lion's mane really help with memory or brain function?
The evidence isn't established in our data. We don't have reliable research yet to say whether it works for Alzheimer disease, cognitive function, or cognitive impairment. That's something to discuss with your doctor if it's important to you.
Can I take this long-term?
Long-term safety as a supplement hasn't been well studied. While it's generally well tolerated as a food, we don't have enough data on long-term use. Check with your pharmacist or doctor about how long you're planning to take it.
