HelloPharmacist Scorecard of Caraway by Herbal Terra

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.

Caraway by Herbal Terra contains one active ingredient: certified organic caraway (Carum carvi) dried fruit liquid extract. Caraway is a traditional herbal remedy used to support digestion; its dried fruit has been studied for relief of indigestion and gas.

The product also contains menstruum, a liquid used to extract the herb.

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 bloating relief.
  • We looked for evidence on: Dyspepsia, Flatulence, Irritable bowel syndrome (IBS), Gas, Indigestion, Digestive upset.
  • 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 possibly effective for indigestion (dyspepsia) — that's where the evidence is strongest. For other uses like absent menstrual periods (amenorrhea), asthma, constipation, and gas (flatulence), the evidence we hold is insufficient to rate it either way, so we can't tell you whether it works for those.

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 supplements and caraway oil are less studied, so we know less about their safety profile.

The data advises against medicinal or oil amounts during pregnancy; food amounts are likely fine, but the evidence is limited. While breastfeeding, food amounts appear safe, but concentrated supplements haven't been well studied — talk with your pharmacist or doctor if you're considering this while nursing.

In reported cases, caraway oil combined with peppermint oil has caused allergic reactions in someone with a history of asthma, and also substernal burning, belching, nausea, and vomiting — though it's unclear whether caraway, peppermint, or the combination caused these effects.

Side effects, ingredient by ingredient Caraway

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 you start, check with your pharmacist if you take any sedating drugs (CNS depressants), diabetes medications, diuretics (especially potassium-depleting ones), lithium, or the TB antibiotics isoniazid, rifampin, or pyrazinamide. These are the medication types where interactions are documented.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Caraway is possibly effective for indigestion and is generally well tolerated in food amounts. If you take diabetes drugs, sedating medications, diuretics, lithium, or certain TB antibiotics, you'll want to check with your pharmacist before starting — the interactions are theoretical but documented.

Pregnant people should avoid medicinal doses.

certified organic Caraway (Carum carvi) dried fruit liquid extract7 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.
