HelloPharmacist Scorecard of Caraway 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 Jul 11, 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: Caraway Fruit Extract, Dry. Caraway is a seed used traditionally to ease indigestion and related stomach symptoms.

The liquid form also contains alcohol, water, and glycerin as inactive ingredients to deliver the extract.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: digestive health and gas relief.
  • We looked for evidence on: Dyspepsia, Flatulence, Irritable bowel syndrome (IBS), Bloating, Indigestion.
  • The strongest evidence on file: Caraway is rated "Possibly Effective" for Dyspepsia (Natural Medicines).
  • Also on file: Caraway is rated "Insufficient Reliable Evidence To Rate" for Flatulence, Irritable bowel syndrome (IBS).

Caraway is rated Possibly Effective for dyspepsia—that's indigestion or upset stomach from eating. For other uses like amenorrhea (absence of periods), asthma, constipation, and flatulence, the evidence isn't established well enough for us to rate it.

If you're taking this for indigestion, there's some support; for other conditions, the data we hold doesn't confirm it works.

The evidence, ingredient by ingredient Caraway

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.

Caraway in food amounts is generally well tolerated. Concentrated oil and supplement doses are less studied, so there's more uncertainty there.

The product advises against medicinal or oil amounts during pregnancy, though food amounts are likely fine—data are limited either way. While breastfeeding, food amounts are probably okay, but safety of concentrated supplements isn't well studied.

A rare allergic reaction and digestive upset (substernal burning, belching, nausea, vomiting) have been reported in patients using caraway oil mixed with peppermint oil, though it's unclear which ingredient caused it.

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 — Caraway.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications; lithium.
  • For scale: 413 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 starting, double-check your blood sugar medications, water pills (especially those that lower potassium), lithium, sedating medications (CNS depressants), and tuberculosis drugs like isoniazid, rifampin, or pyrazinamide. The most serious concern is blood sugar control.

Caraway Fruit Extract, Dry7 drug types · 413 drugs

Antidiabetes Drugs

Theoretically, caraway might increase the risk of hypoglycemia when used with antidiabetes drugs.
Animal research suggests that caraway can reduce blood glucose levels. Monitor blood glucose levels closely. Medication dose adjustments may be necessary.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, caraway might increase the effects and adverse effects of CNS depressants.
Animal research suggests that (S)-(+)-carvone, a major constituent of caraway seed extract, has sedative effects.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, caraway might increase the risk of hypokalemia when used with diuretics that deplete potassium.
Animal research suggests that a single dose of caraway fruit extract can promote diuresis and increase the urinary excretion of sodium and potassium. However, sub-chronic use of caraway fruit extract does not seem to significantly increase potassium excretion, although urine output continues to be increased for up to 6 days.

Likelihood Possible Evidence D
Lithium

Theoretically, caraway might reduce excretion and increase levels of lithium due to diuretic effects.
Animal research suggests that caraway fruit extract has diuretic properties.

Likelihood Possible Evidence D
Isoniazid

Theoretically, caraway might increase the effects and adverse effects of isoniazid.
Animal research suggests that a specific fraction of caraway seed extract (CC-1a) can increase plasma levels of isoniazid when administered concomitantly. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Pyrazinamide

Theoretically, caraway might increase the effects and adverse effects of pyrazinamide.
Animal research suggests that a specific fraction of caraway seed extract (CC-1a) can increase plasma levels of pyrazinamide when administered concomitantly. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Rifampin (Rifadin)

Theoretically, caraway might increase the effects and adverse effects of rifampin.
Animal research suggests that a specific fraction of caraway seed extract (CC-1a) can increase plasma levels of rifampin when administered concomitantly. This interaction has not been reported in humans.
