HelloPharmacist Scorecard of Ajwain 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.

From our pharmacy team — supplement deep dive

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 liquid supplement contains one active ingredient: ajwain seed extract, dry (also called bishop's weed). The extract also includes 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 Bishop's Weed product and its label doesn't state a use — see Bishop's Weed'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.

We don't have effectiveness data on file for ajwain seed extract in our database, so we can't tell you what it's intended to do or how well it works for any particular use.

The evidence, ingredient by ingredient Bishop's Weed

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.

Ajwain seed extract contains light-sensitizing compounds and carries real safety concerns. Taken by mouth, it's been reported to cause nausea, vomiting, and headache.

Applied to skin, it can trigger photoreactive reactions, phototoxicity, and contact dermatitis — in one case, a person experienced allergic contact reactions after handling the plant. The safety data advises against using this product during pregnancy.

Safety while breastfeeding is unknown, so it's best avoided then too. Because the plant contains potentially harmful compounds, the safety notes emphasize use only under medical supervision.

Side effects, ingredient by ingredient Bishop's Weed

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 — Bishop's Weed.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 955 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.

Check with your pharmacist before using this if you take blood thinners or antiplatelet drugs (aspirin, warfarin, clopidogrel, enoxaparin, heparin, and others), medications processed by CYP3A4 (certain anxiety meds, heart drugs, statins, and immunosuppressants), or photosensitizing drugs (tetracyclines, quinolones like ciprofloxacin, sulfa antibiotics, or tricyclic antidepressants). Use the search tool on this page to check your specific medications.

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.

If you take any prescription medication — especially blood thinners, antibiotics, heart drugs, or psychiatric medications — talk to your pharmacist or doctor before starting this product. The photosensitivity risk means you'll need to protect your skin from sunlight carefully while taking it.

This isn't a product to use on your own without professional guidance.

Ajwain Seed Extract, Dry3 drug types · 954 drugs

Anticoagulant/Antiplatelet Drugs

Bergapten, a constituent of bishop's weed, has antiplatelet activity. Theoretically, bishop's weed might have additive effects with anticoagulant or antiplatelet drugs and possibly increase the risk of bleeding.
Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Bergapten, a constituent of bishop's weed, has been shown to inhibit cytochrome P450 3A4 (CYP3A4) in vitro. Theoretically, bishop's weed might inhibit elimination and increase blood levels of drugs metabolized by CYP3A4.
Some drugs metabolized by CYP3A4 include alprazolam (Xanax), amitriptyline (Elavil), amiodarone (Cordarone), buspirone (Buspar), cerivastatin (Baycol), citalopram (Celexa), felodipine (Plendil), fexofenadine (Allegra), itraconazole (Sporanox), ketoconazole (Nizoral), lansoprazole (Prevacid), losartan (Cozaar), lovastatin (Mevacor), ondansetron (Zofran), prednisone (Deltasone, Orasone), sertraline (Zoloft), sibutramine (Meridia), sildenafil (Viagra), simvastatin (Zocor), verapamil (Calan, Covera-HS, Isoptin), and many others.

Likelihood Possible Evidence B
Photosensitizing Drugs

Bishop's weed constituents seem to cause photosensitivity. Theoretically, concomitant use of bishop's weed with photosensitizing drugs might result in increased photosensitivity.
Some drugs that cause photosensitivity include amitriptyline (Elavil), quinolones (Ciprofloxacin, others), sulfa drugs (Septra, Bactrim, others), and tetracycline.

Ajwain by Herbal Terra: Common Questions

Does Ajwain by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Ajwain has a known interaction with 954 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Ajwain 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 use this while pregnant?
No. The safety data rates this product as likely unsafe during pregnancy, so it should be avoided. Talk with your doctor or midwife about whether this is right for you.
Is it safe to use while breastfeeding?
Safety while breastfeeding is unknown. Because there isn't enough data to know either way, it's best avoided. Chat with your pharmacist or doctor if you're considering it.
What side effects might I experience?
Taken by mouth, ajwain has been reported to cause nausea, vomiting, and headache. If applied to skin, it may cause photoreactive reactions, redness, burning, or contact dermatitis. Because it contains light-sensitizing compounds, you'll also need to be very careful about sun exposure.
Why does the label say to use this only under medical supervision?
Ajwain contains compounds that can be toxic and interact with many medications. It also makes your skin extra sensitive to sunlight. Those risks mean you shouldn't start it without a healthcare provider watching and guiding your use.
Does this product have any fillers?
Yes. The inactive ingredients are alcohol, water, and glycerin — these are used as the liquid base and preservative.
