HelloPharmacist Scorecard of Butternut 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
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: butternut inner bark extract in a dry form. Butternut acts as a stimulant laxative, meaning it prompts your bowels to move by triggering muscle contractions.

The liquid is prepared with alcohol, water, and glycerin 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 Butternut product and its label doesn't state a use — see Butternut'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 facts we hold don't include effectiveness ratings for butternut, so we can't tell you whether the evidence supports its use for any particular purpose.

The evidence, ingredient by ingredient Butternut

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.

Butternut is generally well tolerated by mouth, though it commonly causes diarrhea and gastrointestinal irritation, including cramping and digestive upset. Because it works as a laxative and safety data are limited, the facts advise against using it during pregnancy.

There isn't enough safety information to use it while breastfeeding either — talk with your doctor or pharmacist about whether it's right for you in either situation.

Side effects, ingredient by ingredient Butternut

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 — Butternut.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; heart-rhythm medications.
  • For scale: 122 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 butternut, double-check with your doctor or pharmacist if you use blood thinners like warfarin, water pills (diuretics), steroid medications, digoxin (Lanoxin), or other laxative drugs. All of these carry moderate interaction risk with butternut's laxative effects.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Butternut is a laxative herb suited to people looking for bowel stimulation, but it's risky if you take blood thinners, water pills, steroids, heart medications like digoxin, or other laxatives. Pregnant and breastfeeding people should avoid it.

Check with your doctor or pharmacist before adding it to your routine, especially if you're on any regular medication.

Butternut Inner Bark Extract, Dry5 drug types · 122 drugs

Corticosteroids

Butternut has stimulant laxative effects. Theoretically, concomitant use of corticosteroids with butternut can increase the risk of potassium depletion.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Butternut has stimulant laxative effects. Theoretically, potassium depletion associated with butternut might increase the risk of digoxin toxicity.

Likelihood Possible Evidence D
Diuretic Drugs

Butternut has stimulant laxative effects. Theoretically, overuse of butternut might compound diuretic-induced potassium loss. There is some concern that people receiving butternut along with potassium-depleting diuretics might be at an increased risk for hypokalemia.
Some diuretics that can deplete potassium include chlorothiazide (Diuril), chlorthalidone (Thalitone), furosemide (Lasix), hydrochlorothiazide (HCTZ, Hydrodiuril, Microzide), and others.

Likelihood Possible Evidence D
Stimulant Laxatives

Butternut has stimulant laxative effects. Concomitant use with stimulant laxative medications might compound fluid and electrolyte loss.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Butternut has stimulant laxative effects. In some people butternut can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Advise patients who take warfarin not to take excessive amounts of butternut.

Butternut by Hawaii Pharm: Common Questions

Does Butternut by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Butternut has a known interaction with 122 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Butternut 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 butternut if I'm on warfarin?
Not without checking first. Butternut can trigger diarrhea, which increases how much warfarin your body absorbs and raises your bleeding risk. Talk to your doctor or pharmacist before using butternut if you take warfarin, and if you do use it, avoid large amounts.
What side effects should I expect?
Diarrhea and gastrointestinal irritation are the main ones — butternut is a laxative, so cramping and digestive upset are fairly common. Most people tolerate it okay, but these effects are typical.
Is butternut safe to use while pregnant or breastfeeding?
No — the safety data advise against it during both pregnancy and breastfeeding. Talk with your doctor or pharmacist about safer options during these times.
Can I use butternut with my water pill?
Probably not without talking to your doctor first. Both butternut and diuretics lower potassium, and using them together raises the risk of dangerously low potassium levels.
What is butternut inner bark extract?
It's an extract from the inner bark of the butternut tree, prepared as a dry form in this liquid. Butternut has been used as a stimulant laxative to encourage bowel movements.
