HelloPharmacist Scorecard of Pumpkin 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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 3, 2026

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: pumpkin seed extract in dry form. It comes in a liquid base made of alcohol, water, and glycerin.

Does it work?

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded Pumpkin's overall clinical evidence instead.

Moderate

Some clinical evidence supports Pumpkin for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Benign prostatic hyperplasia (BPH) — rated "Possibly Effective" (Natural Medicines).

The evidence is strongest for benign prostatic hyperplasia (BPH) — enlarged prostate — where pumpkin seed extract is rated possibly effective. For androgenic alopecia (male-pattern hair loss), interstitial cystitis (bladder pain), intestinal parasite infection, and urinary tract infections, the evidence we hold is insufficient to rate whether it works.

The evidence, ingredient by ingredient Pumpkin

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.

Pumpkin as a food is generally well tolerated. As a concentrated seed supplement like this one, it's generally safe for most adults, though the long-term safety data isn't as robust as we'd like.

The most common side effects in trials are abdominal discomfort, diarrhea, nausea, and vomiting. Rarely, anaphylaxis (a severe allergic reaction) has been reported.

There are also two case reports of substantial hair loss occurring 1–3 weeks after consuming bitter-tasting pumpkin or squash with high cucurbitacin levels — a compound found mainly in wild varieties, not typical supplement products. During pregnancy or breastfeeding, there isn't enough safety data on concentrated pumpkin seed supplements to know either way — talk with your doctor or pharmacist for personalized advice.

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 — Pumpkin.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 1 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.

If you take lithium, check with your doctor or pharmacist before starting this product — pumpkin seed extract may increase lithium levels and require a dose adjustment (Moderate interaction).

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Pumpkin seed extract may help with an enlarged prostate, though the evidence for other uses isn't established. If you take lithium, don't start this supplement without checking with your doctor or pharmacist first — it may raise your lithium level.

For most other people, it's generally well tolerated, but mild digestive upset can happen.

Pumpkin by Hawaii Pharm: Common Questions

Does Pumpkin by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Pumpkin has a known interaction with 1 medication. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Pumpkin 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.
Will this help my enlarged prostate?
Pumpkin seed extract is rated possibly effective for benign prostatic hyperplasia (BPH). That's a fair amount of evidence, though not ironclad — talk with your doctor about whether it makes sense for you alongside any other treatments you're on.
What side effects should I watch for?
Most people tolerate it well. The common ones in trials were mild — abdominal discomfort, diarrhea, nausea, and vomiting. Anaphylaxis (severe allergic reaction) is rare but has been reported. If you experience severe symptoms, stop and reach out to your doctor or pharmacist right away.
Can I take this if I'm pregnant or breastfeeding?
There isn't enough safety data on concentrated pumpkin seed supplements in pregnancy or breastfeeding to know either way. Talk with your doctor or pharmacist — they can weigh what you need against what we know.
Why does it contain alcohol?
Alcohol is one of the inactive ingredients in this liquid form — it helps extract and preserve the pumpkin seed extract. The amount per dose is typically small.
Will this help with hair loss?
The evidence we hold is insufficient to say whether pumpkin seed extract works for androgenic alopecia (male-pattern hair loss). There's not enough reliable data yet to rate it one way or the other.
