HelloPharmacist Scorecard of Basil 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

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: Basil Leaf Extract, Dry. The liquid formulation also includes alcohol, water, and glycerin as inactive ingredients to deliver the extract.

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 Basil product and its label doesn't state a use — see Basil'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 on basil doesn't establish that it works for acne, headache, common cold, constipation, diarrhea, or flatulence — all of these conditions show insufficient reliable evidence to rate. If you're considering basil for one of these reasons, talk with your pharmacist or doctor about whether the current research supports its use for your situation.

The evidence, ingredient by ingredient Basil

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.

Basil is generally well tolerated when you eat it as food. However, concentrated extracts like this one are less studied, and the safety data available advises caution with medicinal doses and essential oils.

One case of allergic contact dermatitis has been reported in someone with occupational basil exposure, though this is rare. Pregnancy and lactation data show mixed ratings in our files — some sources rate it likely safe and others possibly unsafe — so if you're pregnant or breastfeeding, talk with your doctor or pharmacist before starting.

Side effects, ingredient by ingredient Basil

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 — Basil.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 289 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 any blood thinners (anticoagulants or antiplatelet drugs) you may take — basil may increase bleeding risk (Moderate severity). Also check blood pressure medications (antihypertensives), as basil may lower your pressure further (Moderate severity).

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.

Basil Leaf Extract is worth considering if you're looking for a traditional herbal option and you don't take blood pressure or blood-thinning medications. If you're on either of those drug types, check your specific medications with our tool before starting.

Talk with your pharmacist about whether a concentrated extract is right for you, especially since food amounts are better studied than supplements.

Basil by Herbal Terra: Common Questions

Does Basil by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Basil has a known interaction with 289 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Basil 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.
Is basil safe to use while I'm pregnant or breastfeeding?
Our data shows mixed safety ratings for basil in pregnancy and lactation — some sources rate it likely safe and others possibly unsafe. There isn't enough clear evidence to say yes or no. Talk with your doctor or pharmacist about what's right for your situation.
Can this product cause allergic reactions?
Allergic contact dermatitis from basil has been reported, though it's rare and was documented in someone with heavy occupational exposure. If you've had allergies to basil or related plants before, be cautious and watch for skin reactions.
Is this extract safer than basil essential oil?
Basil as food is well studied and generally safe, but concentrated extracts and essential oils are less studied. Safety data isn't established for medicinal doses or essential oils, so they warrant extra caution — talk with your pharmacist about the safest form for what you need.
Does basil actually work for colds, headaches, or digestion?
We don't have reliable evidence in our data to show that basil works for common cold, headache, constipation, diarrhea, or flatulence. If you're considering it for one of these, ask your pharmacist what the broader research shows.
What's in this liquid besides the basil extract?
The formula includes alcohol, water, and glycerin to deliver the extract. If you need to avoid alcohol, check the label for the exact amount or ask us for an alternative form.
