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

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: certified organic Vana Holy Basil leaf extract in liquid form. The extract comes from dried holy basil leaves and is suspended in a menstruum—the liquid medium used to make the extract.

There are no other active ingredients.

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 Holy Basil product and its label doesn't state a use — see Holy 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 for holy basil doesn't support its use for any condition yet. The data shows insufficient reliable evidence for generalized anxiety disorder, asthma, headache, respiratory tract infections, dental plaque, and diabetes.

That doesn't mean it doesn't work—it means the clinical trials so far haven't been strong or numerous enough to confirm whether it does.

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, but we don't have enough long-term safety data to know how it performs over months or years. The most common side effects are loose stools and nausea when taken by mouth—a small number of trial participants experienced these.

Because animal data raise safety concerns, the facts advise against using it during pregnancy. While breastfeeding, there isn't enough reliable safety information, so it should be avoided as well.

Side effects, ingredient by ingredient Holy 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 — 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 taking this product, double-check your medications if you take blood thinners (anticoagulants or antiplatelet drugs)—holy basil theoretically raises bleeding risk. Also check if you use diabetes medications, since holy basil may lower blood sugar.

If you take pentobarbital or other sedatives, mention this product to your pharmacist. Use the medication checker on this page for your exact drugs.

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.

Vana Holy Basil is a single-ingredient liquid extract generally well tolerated short-term, but with documented interactions with blood thinners, diabetes medications, and pentobarbital. If you take any of those—or any other regular medication—check it against the tool on this page before you start.

Talk with your pharmacist or doctor about whether it's right for you, especially if you're pregnant or breastfeeding.

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.
What does holy basil actually do?
We don't have enough reliable evidence yet to confirm that holy basil works for any specific condition. The research so far hasn't been strong enough to rate its effectiveness for anxiety, asthma, headache, infections, dental plaque, or diabetes, even though people use it for those.
Is this safe to take long-term?
Holy basil extract is generally well tolerated in the short term, but we don't have good long-term safety data. If you're thinking about taking it regularly for months or longer, that's a good conversation to have with your pharmacist.
What are the side effects?
The most common ones are loose stools and nausea when you take it by mouth. A small number of people in clinical trials experienced these. Since this is a liquid form, you might also notice a bitter taste.
Can I take this while pregnant or breastfeeding?
The safety data advises against using holy basil during pregnancy. While breastfeeding, there isn't enough reliable safety information, so it should be avoided. Talk with your doctor or pharmacist about what's right for your situation.
Does it interact with my diabetes medication?
Yes—holy basil can lower blood sugar levels, so taking it with diabetes drugs theoretically increases the risk of low blood sugar. You'll want to check this with your pharmacist before starting.
