HelloPharmacist Scorecard of Basil Alcohol Free 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 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 supplement contains one active ingredient: basil leaf extract (dried). Basil is an herb traditionally used in cooking and herbal medicine, though this product concentrates it in liquid form.

The inactive ingredients are glycerin and water, which serve as the carrier and preservative.

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 doesn't establish that basil leaf extract is effective for acne, headache, common cold, constipation, diarrhea, or flatulence. Each of these uses is rated as having insufficient reliable evidence to rate, meaning the research isn't there yet to confirm whether it works.

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—it's a common kitchen herb. However, concentrated extracts like this one are less studied for safety.

The safety notes advise sticking to food amounts rather than medicinal doses or essential oils because the data on concentrated supplements isn't solid enough yet. One case of allergic contact dermatitis (a skin rash from direct contact) has been reported, though it was tied to occupational exposure rather than taking basil as a supplement.

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, check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (like warfarin, aspirin for heart protection, or clopidogrel)—basil may increase bleeding risk. Also confirm it's safe if you're on blood pressure medication, since basil extract may lower BP further.

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 Alcohol Free is a single-ingredient extract that's generally well tolerated at food doses, but you'll want to check it against any blood pressure or blood-thinning medications you take before starting. The evidence doesn't yet support its use for common complaints like headache or digestive issues.

Talk it over with your doctor or pharmacist, especially if you're on medications or pregnant.

Basil Alcohol Free by Hawaii Pharm: Common Questions

Does Basil Alcohol Free by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Basil Alcohol Free 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 Alcohol Free 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.
Will this basil extract actually help my headache or cold?
The evidence we hold doesn't show that basil extract is effective for headache or common cold. Both uses are rated as having insufficient reliable evidence, so we can't say whether it works.
Is basil safe to take as a supplement, or just as food?
Basil as food is safe and well tolerated. Concentrated supplements and medicinal doses are less studied, so the safety data isn't as solid. If you're using it beyond food amounts, talk with your doctor or pharmacist about whether it's right for you.
Can I take this if I'm pregnant or breastfeeding?
The data is conflicting—basil is rated both Likely Safe and Possibly Unsafe during pregnancy and lactation. Talk with your doctor or pharmacist to figure out what's right for your situation before using this product.
What's the difference between this and basil essential oil?
This is a basil leaf extract in liquid form. The safety notes advise against basil essential oil because it's even less studied than concentrated extracts like this one. If you're choosing between them, that's a conversation to have with your pharmacist.
