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: Phragmites communis Root Extract (also called Reed Herb). The liquid formulation also includes glycerin and water as inactive ingredients.

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 Reed Herb product and its label doesn't state a use — see Reed Herb'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 effectiveness data we hold for Phragmites communis Root Extract shows insufficient reliable evidence to rate it for breast cancer, diabetes, leukemia, or insect bites. In other words, there isn't enough solid research to say whether it works for these purposes.

If you're considering it for any of these uses, talk with your doctor about what the current evidence supports.

How safe is it?

Limited data
Safety Information · database check
Limited information

Little studied safety information is available for these ingredients — that is not the same as being safe.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Phragmites communis Root Extract is traditionally used and generally well tolerated, but human safety data are limited. The safety data advises against using it during pregnancy or while breastfeeding because there isn't enough information to know it's safe in those situations.

If you're pregnant, breastfeeding, or planning to become pregnant, talk with your doctor or pharmacist before starting this product.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and safety information is limited.

Lu Gen Alcohol Free is a traditionally used herbal liquid with limited modern safety and effectiveness data. No interactions with medications are documented for its ingredient, but that doesn't mean none exist.

If you're pregnant, breastfeeding, or taking any medications, check with your own doctor or pharmacist before you start.

Lu Gen Alcohol Free by Hawaii Pharm: Common Questions

Does Lu Gen Alcohol Free by Hawaii Pharm interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Lu Gen Alcohol Free. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Lu Gen 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 Lu Gen Alcohol Free if I'm pregnant?
The safety data advises against it — there isn't enough information to know it's safe during pregnancy. Talk with your doctor or pharmacist before you use it if you're pregnant or planning to become pregnant.
Is it safe to use while breastfeeding?
No, the safety data says to avoid it while breastfeeding because there's no reliable safety information available. Check with your doctor or pharmacist about whether it's right for you if you're nursing.
Does this product actually work?
The evidence we hold shows insufficient reliable data to rate it for breast cancer, diabetes, leukemia, or insect bites. There isn't enough solid research to say whether it works for these purposes, so talk with your doctor about what science currently supports.
What is Phragmites communis Root Extract used for?
It's traditionally used for several purposes, including support for breast cancer, diabetes, leukemia, and insect bites. However, the research backing these uses is limited, so the evidence is insufficient to confirm whether it works.
Are there any side effects I should know about?
The adverse effects data we hold are empty — we don't have documented side effects from trials. That said, human safety data for this ingredient are limited, so if you experience any unusual symptoms after starting it, talk with your pharmacist or doctor.
