HelloPharmacist Scorecard of Organic 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 Aug 27, 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, delivered as a liquid concentrate. Basil oil and basil extract make up the active portion.

The product also contains steam-distilled basil oil as an inactive ingredient. This is a concentrated form rather than whole basil as you'd use it in cooking — the extract and essential oil are more potent and less studied than basil in food amounts.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Basil's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: skin health and menstrual discomfort relief.
  • We looked for evidence on: Acne, Headache, menstrual cramps, skin aging.
  • The closest evidence on file: Basil is rated "Insufficient Reliable Evidence To Rate" for Acne (Natural Medicines).
  • Also on file: Basil is rated "Insufficient Reliable Evidence To Rate" for Headache.

The evidence we hold on basil doesn't support claims for acne, headache, common cold, constipation, diarrhea, or flatulence — we have insufficient reliable data to rate it for any of these uses. If you're considering basil for a specific health purpose, talk with your doctor or pharmacist about whether the current evidence supports it 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 eaten as food is generally well tolerated. However, this product is a concentrated extract and essential oil — safety data for these forms is not established.

The caution here is to avoid medicinal doses and essential oil due to that lack of safety data; food amounts are likely fine. One case of allergic contact dermatitis has been reported from occupational exposure.

Pregnancy and lactation data on file show conflicting ratings — one entry notes "Likely Safe" and another notes "Possibly Unsafe." Because the data is unclear, talk with your doctor or pharmacist before taking this product if you're pregnant or breastfeeding.

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 (such as warfarin, dabigatran, or aspirin) or blood pressure medications — basil may increase bleeding risk or lower your blood pressure further. These are Moderate-severity interactions.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Organic Basil is a concentrated liquid that may work with blood thinners and blood pressure medications in ways that need checking first — especially because safety data for this concentrated form is limited. If you take any of those medications or anything else by prescription, confirm the fit with your own doctor or pharmacist before you start.

Food amounts of basil are generally well tolerated, but this is a more potent product.

Organic Basil by Zongle Therapeutics: Common Questions

Does Organic Basil by Zongle Therapeutics interact with any medications?
Yes. Based on its ingredients, Organic 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?
Organic 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.
Does basil really work for colds, headaches, or digestive issues?
According to the data we hold, there isn't enough reliable evidence to say whether basil helps with any of those — acne, headache, common cold, constipation, diarrhea, or gas all fall into that "insufficient evidence" category. Your doctor or pharmacist can discuss whether there's other research outside our data or whether it makes sense to try it for your situation.
Is this safe if I eat basil normally in cooking?
Basil as food is generally well tolerated. This product is a concentrated extract and essential oil, though — a much more potent form with less safety data. The caution is to avoid medicinal doses and essential oil; food amounts are likely fine.
Can I take this if I'm pregnant or breastfeeding?
The data on file is conflicting — one entry says "Likely Safe" and another says "Possibly Unsafe." Because there's uncertainty, talk with your doctor or pharmacist before taking it if you're pregnant or breastfeeding. They can weigh the specifics of your situation.
What's actually in this liquid — is it just basil?
The active ingredient is basil oil and basil extract. The product also contains steam-distilled basil oil as an inactive ingredient. It's a concentrated form, not whole basil leaves.
What side effects might I see?
Allergic contact dermatitis has been reported in one case from occupational exposure to basil. Because this is a concentrated product with less safety data, any new rash or unusual reaction warrants a call to your pharmacist or doctor.
