HelloPharmacist Scorecard of Duckweed Alcohol Free by Hawaii Pharm

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.

From our pharmacy team — supplement deep dive

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: duckweed herb extract (dry form). Duckweed is a small aquatic plant that's been used as food in some cultures and studied for potential health benefits.

The extract is suspended in a liquid base made of glycerin and water, with no added alcohol.

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 Duckweed product and its label doesn't state a use — see Duckweed'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 duckweed in treating respiratory tract infections, rheumatoid arthritis, and gout is insufficient to rate. In other words, we don't have enough reliable data right now to say whether it works for any of these uses.

If you're considering it for a specific health concern, it's worth asking your doctor what the research actually shows.

The evidence, ingredient by ingredient Duckweed

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 0 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.

Duckweed is eaten as a food in some cultures, but when it comes to supplement quality and potential water contamination, real concerns exist — the safety data isn't robust enough for a clear thumbs-up. There isn't enough reliable safety information to recommend it outright, and safety during breastfeeding hasn't been established.

If you're pregnant or nursing, talk with your doctor or pharmacist before taking this product. No adverse effects were reported in the data we hold, but that doesn't mean none can occur.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and some safety-information gaps remain.

Duckweed Alcohol Free may appeal to someone interested in traditional plant extracts, but the evidence for what it actually does is thin. If you're pregnant, breastfeeding, or have concerns about supplement purity and water quality, it's worth a conversation with your doctor or pharmacist first.

No medication interactions are documented, but that's one piece of a larger safety picture.

Duckweed Alcohol Free by Hawaii Pharm: Common Questions

Does Duckweed Alcohol Free by Hawaii Pharm interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Duckweed Alcohol Free. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Duckweed 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.
Is duckweed safe to take while breastfeeding?
Safety during breastfeeding hasn't been established, so it's not recommended. Talk with your doctor or pharmacist about whether this product is right for you.
Does this actually work for respiratory infections or arthritis?
The evidence we have is insufficient to say. We don't have enough reliable data to rate whether duckweed works for those uses.
What's the main concern with duckweed supplements?
Supplement quality and water contamination are real worries. Duckweed grows in water, and if that water isn't clean, the extract won't be either. That's why safety data matters.
Are there any side effects listed for this product?
No adverse effects were reported in the data we hold, but that doesn't guarantee none can happen. If you develop symptoms after starting it, talk with your doctor.
Can I take this with my medications?
No interactions are documented for duckweed, but check your specific medications using the tool on this page or with your pharmacist to be sure.
