HelloPharmacist Scorecard of Basil by Zongle Therapeutics

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: basil, supplied as a liquid. The inactive ingredients include basil oil that's been steam-distilled.

Basil is an herb used in cooking and traditional medicine, though most of the research on its effects comes from concentrated extracts and essential oils rather than the food form you'd use in the kitchen.

Does it work?

Insufficient 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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: promotes alertness and reduces anxiety.
  • We looked for evidence on: Mental alertness, anxiety, stress, cognitive function.
  • The closest evidence on file: Basil is rated "Insufficient Reliable Evidence To Rate" for Mental alertness (Natural Medicines).

The evidence for basil as a treatment isn't established in the data we hold. We have insufficient reliable evidence to rate it for acne, headache, common cold, constipation, diarrhea, or flatulence.

That doesn't mean it doesn't work — it means the research either isn't there yet or isn't solid enough to draw a conclusion.

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 used as a food in normal cooking amounts is generally well tolerated. The safety data for concentrated extracts and essential oils (which is what you're getting in a supplement) is much thinner.

The safety notes caution against medicinal doses and essential oils because we don't have enough data on them yet. One case of allergic contact dermatitis has been reported in someone with occupational exposure to basil, though this is uncommon.

For pregnancy and lactation, the data is mixed: basil is rated both likely safe and possibly unsafe depending on the context and dose. Because the evidence is unclear, talk with your doctor or pharmacist about whether it's right for you during pregnancy or while breastfeeding.

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.

If you take blood pressure medication (antihypertensives) or blood thinners and antiplatelet drugs, check with your doctor or pharmacist before starting this product. Both interactions are Moderate-severity risks.

The bottom line

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

Basil is an herb you probably know from cooking, but taking it as a supplement is different — the safety data for concentrated forms is limited. If you take blood pressure medication or blood thinners, you'll want to check with your doctor or pharmacist before adding this.

For everyone else, weigh the lack of established effectiveness against the gaps in safety data with your own healthcare provider.

Basil by Zongle Therapeutics: Common Questions

Does Basil by Zongle Therapeutics 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 eat as a food versus taking it as a supplement?
Basil in normal food amounts is generally well tolerated. The concentrated extracts and essential oils used in supplements haven't been studied as thoroughly, so safety data for medicinal doses is limited.
Can I take this if I'm pregnant or breastfeeding?
The data is unclear — basil is rated both likely safe and possibly unsafe depending on context and dose. Talk with your doctor or pharmacist for personalized advice before starting it.
Does basil actually work for acne, colds, headaches, or digestive issues?
We don't have reliable evidence to say whether basil works for any of these. The research either isn't there yet or isn't strong enough to draw a solid conclusion.
What's in this product besides basil?
The inactive ingredient is basil oil that's been steam-distilled. These are excipients used to make the supplement, not active therapeutic ingredients.
Can I have an allergic reaction to basil?
Allergic contact dermatitis — a skin reaction — has been reported in one person with occupational exposure, though this is uncommon. If you have known allergies to basil or related plants, talk with your pharmacist.
