HelloPharmacist Scorecard of Vana Holy 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 a single active ingredient: Vana Holy Basil Leaf Extract (in dry form). The other ingredients — alcohol, water, and glycerin — are inactive components that help deliver and preserve the extract in liquid form.

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: Stress and general wellness support.
  • We looked for evidence on: Stress, Generalized anxiety disorder (GAD), Insomnia, Respiratory tract infections, Anxiety, Immune support — and 1 related terms.
  • The closest evidence on file: Holy Basil is rated "Insufficient Reliable Evidence To Rate" for Generalized anxiety disorder (GAD) (Natural Medicines).
  • Also on file: Holy Basil is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections, Insomnia, Stress.

The evidence for holy basil in our data shows insufficient reliable evidence to rate its use for generalized anxiety disorder, asthma, headache, respiratory tract infections, dental plaque, or diabetes. That means the studies we have don't yet support or rule out benefit for these conditions.

If you're looking for a particular effect, talk with your pharmacist or doctor about what's been shown to help.

The evidence, ingredient by ingredient Holy 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.

Holy basil extract is generally well tolerated in the short term, though long-term safety data in humans are limited. The most common side effects from oral use are loose stools and nausea — a small number of trial participants reported these.

If used topically (like as a mouthwash), it may leave a bitter taste. Because animal safety data raise concerns and human safety in pregnancy isn't established, avoid this product if you're pregnant.

Similarly, there isn't enough reliable safety information for breastfeeding, so don't use it while nursing — talk with your doctor or pharmacist about what's safe for you.

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 — Holy Basil.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 212 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 starting Vana Holy Basil, check whether you take blood thinners or antiplatelet drugs (Moderate risk), diabetes medications (Moderate risk), or pentobarbital or other sedatives (Moderate risk). Even though human data are limited, animal research shows real potential for interactions in these categories.

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.

Holy basil may be worth considering if you're exploring herbal options for anxiety or other uses, but the evidence in our data doesn't yet support effectiveness for any condition. If you take blood thinners, diabetes medications, or sedatives, you need to check with your pharmacist or doctor first.

Pregnant or breastfeeding — skip it and ask your healthcare provider what's safe.

Vana Holy Basil by Herbal Terra: Common Questions

Does Vana Holy Basil by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Vana Holy Basil has a known interaction with 212 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Vana Holy 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.
Will holy basil lower my blood sugar if I take diabetes medication?
Holy basil may lower blood sugar based on small clinical studies, so if you're on diabetes drugs, combining them could theoretically increase the risk of low blood sugar. You'll need to talk with your doctor or pharmacist before adding this — they can advise whether it's right for you and whether you need to monitor your glucose differently.
What are the most common side effects?
When taken by mouth, loose stools and nausea are the most common side effects, though they were rare in the studies we reviewed — only a small number of participants reported them. If used as a mouthwash or topical product, it can leave a bitter taste.
Is it safe to take while pregnant or breastfeeding?
No — the safety data advise against use in pregnancy because animal data raise concerns and human safety isn't established. Similarly, there isn't enough reliable safety information for breastfeeding, so avoid it while nursing. Talk with your doctor or pharmacist about what's safe for you in either situation.
How long can I safely use this product?
Holy basil seems well tolerated in the short term in adults, but high-quality long-term safety data in humans are limited. If you're thinking of using it regularly over months, it's worth checking in with your pharmacist or doctor about what we know and don't know.
Does it actually work for anxiety or other conditions?
The evidence in our data shows insufficient reliable evidence to rate holy basil for generalized anxiety, asthma, headache, respiratory infections, dental plaque, or diabetes. That means we don't yet have strong proof it helps — talk with your doctor about whether it makes sense to try it alongside other approaches.
