HelloPharmacist Scorecard of Bay Leaf 450 mg by TerraVita Premium Collection

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 16, 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: bay leaf, a culinary herb supplied at 450 mg per capsule. The capsule itself is made from gelatin and water.

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 Bay Leaf product and its label doesn't state a use — see Bay Leaf'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 evidence we hold doesn't establish that bay leaf works for any of the conditions listed — dandruff, diarrhea, painful periods (dysmenorrhea), boils, or the common cold all show insufficient reliable evidence to rate its effectiveness. That doesn't mean it doesn't work; it means the research data we have isn't strong enough to say one way or the other.

The evidence, ingredient by ingredient Bay Leaf

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.

Bay leaf is generally well tolerated when you eat it as a food seasoning or use the powdered leaf as a supplement. The main caution: avoid whole, intact leaves, which can cause choking or, rarely, perforate the intestinal lining.

The safety data for medicinal or large doses is limited, so it's best to stick to food amounts or use powdered forms. Topically, bay leaf is usually well tolerated, though allergic reactions and contact dermatitis can occur — one person developed a rash after applying bay leaves under occlusion for two days.

Inhaling bay leaf dust may trigger occupational asthma in some people.

Side effects, ingredient by ingredient Bay Leaf

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 — Bay Leaf.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 335 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 this product, double-check with your doctor or pharmacist if you take sedatives (including sleep aids), antidiabetes drugs, or narcotic pain relievers — all carry Moderate interaction risks with bay leaf. No other medication types are documented to interact with the ingredients we could check.

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.

Bay Leaf 450 mg is generally well tolerated at food levels, but this product supplies a concentrated dose. If you take sedatives, diabetes medications, or narcotics, check with your doctor or pharmacist before starting — the interactions are real and may need dose adjustments or avoidance.

Talk it over with your own healthcare provider to see if it's right for you.

Bay Leaf 450 mg by TerraVita Premium Collection: Common Questions

Does Bay Leaf 450 mg by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Bay Leaf 450 mg has a known interaction with 335 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Bay Leaf 450 mg 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.
What exactly is bay leaf and why is it in a supplement?
Bay leaf is a culinary herb you might recognize from cooking. It's sold as a supplement because traditional medicine has used it for various purposes, though our data shows the evidence for those uses isn't yet strong enough to confirm it works.
I take a diabetes medication. Can I use this?
Not without talking to your doctor first. Preliminary research shows bay leaf can lower blood sugar on its own, so combining it with your diabetes drug could drop your blood sugar too far. Your doctor may be able to adjust your dose, or they may advise against it — it's their call based on your situation.
What are the side effects?
When used as food or as powdered leaf supplement, bay leaf is well tolerated and side effects are rare. The main risk is with whole, unground leaves, which can cause choking. Applied to skin, it may trigger allergic reactions or contact dermatitis in some people.
Is it safe if I'm pregnant or breastfeeding?
Our data doesn't include information on bay leaf safety during pregnancy or lactation. Talk with your doctor or pharmacist before taking this supplement if you're pregnant or nursing — they can advise you based on your individual situation.
What's in the capsule besides bay leaf?
Just gelatin and water — those are the inactive ingredients that make up the capsule shell. The active ingredient is the 450 mg of bay leaf powder inside.
