Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of Duckweed 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.
What’s inside
Full disclosure
Hawaii Pharm Duckweed is a single-ingredient liquid: duckweed extract. The product also contains vegetable palm glycerin and alcohol as inactive ingredients to preserve and carry the extract.
Does it work?
Couldn't assess
The evidence we hold rates duckweed extract as having insufficient reliable evidence to rate for respiratory tract infections, rheumatoid arthritis (RA), and gout. In plain terms: we don't have solid data yet on whether it actually works for these uses.
If you're thinking about using it for one of these conditions, talk it over with your doctor or pharmacist — they can help you weigh what limited evidence exists against other options.
How safe is it?
Some data gaps
Duckweed is considered a food in some cultures, but supplement quality and water contamination are real concerns with plant-based products. The safety data we hold advises against using this product — there isn't enough reliable information to know whether it's safe.
Safety during breastfeeding has not been established, so breastfeeding is not recommended while taking it. We hold no adverse-effect data for duckweed extract in our records.
Meds to double-check
No known interactions
No interactions are documented in our data for duckweed extract with the individual medications we could check. That doesn't mean none exist — it means we hold no interaction monograph for this ingredient.
Before you combine it with any prescription or over-the-counter drug, run your exact medications through the search tool on this page and confirm with your own pharmacist or doctor.
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.
Hawaii Pharm Duckweed extract has no documented medication interactions, but the safety evidence is weak enough that the data advises caution or avoidance. If you're pregnant or breastfeeding, it's not recommended.
Before you take this product — especially if you rely on it regularly — talk it over with your doctor or pharmacist to make sure it fits your individual health picture.
