HelloPharmacist Scorecard of Holy Basil 1600 mg by tnvitamins

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 6, 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: holy basil leaf extract at 1,600 mg per capsule. Holy basil (also called tulsi) is a plant traditionally used in Ayurvedic medicine.

The capsules also contain inactive ingredients — cellulose and rice flour — that help form and fill the capsule.

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 is limited. We have insufficient reliable evidence to rate it for generalized anxiety disorder, asthma, headache, respiratory tract infections, dental plaque, or diabetes — meaning the studies so far are too small or not rigorous enough to say whether it actually works for these uses.

If you're considering it for a specific condition, that's a good conversation to have with your doctor or pharmacist.

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 in adults, but high-quality long-term safety data are limited. In one clinical study, a small number of participants taking holy basil capsules reported nausea or loose stools — the most common side effects reported.

The safety data advises against holy basil during pregnancy and while breastfeeding. Animal data raise concerns, and human safety is not established in these situations, so talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or nursing.

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 holy basil, double-check with your doctor or pharmacist if you're on blood thinners (anticoagulants or antiplatelets), diabetes medications, or pentobarbital or other sedatives. These are Moderate-severity interactions.

If you're on any of these, the supplement may increase bleeding risk, low blood sugar, or sedation — and you'll want personalized advice on whether to take it.

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.

Holy Basil 1600 mg may appeal to people looking for a traditional plant supplement, but the evidence for specific health claims is not yet established in our data. The main caution is its interactions with blood thinners, diabetes drugs, and certain sedatives — all of which can affect how these medications work.

If you take any prescription medication, check with your doctor or pharmacist before starting this product. Avoid it during pregnancy and while breastfeeding.

Small clinical studies show that taking holy basil can decrease fasting blood glucose and other measures of glycemic control in patients with type 2 diabetes.

Likelihood Possible Evidence B
Pentobarbital (Nembutal)

Theoretically, holy basil seed oil might increase the sedative effects of pentobarbital.
Animal research shows that holy basil seed oil increases pentobarbitone-induced sleeping time. However, it is not known if this occurs in humans or if this applies to other barbiturates or sedatives.

Holy Basil 1600 mg by tnvitamins: Common Questions

Does Holy Basil 1600 mg by tnvitamins interact with any medications?
Yes. Based on its ingredients, Holy Basil 1600 mg 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?
Holy Basil 1600 mg 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.
Can I take this if I'm on a blood thinner like warfarin or aspirin?
Not without checking first with your doctor or pharmacist. Animal research suggests holy basil seed oil might increase bleeding risk when combined with blood thinners, though we don't yet know if this happens in people. That's a Moderate-severity interaction worth a conversation with your healthcare provider.
What if I take a diabetes medication?
Talk to your doctor or pharmacist before you start. Holy basil may lower blood sugar, and small studies show it can decrease fasting glucose in people with type 2 diabetes — so together with a diabetes drug, it could raise the risk of low blood sugar (hypoglycemia).
Is it safe to take while pregnant or breastfeeding?
The safety data advises against it in both situations. Animal data raise concerns and human safety is not established, so if you're pregnant, planning to become pregnant, or nursing, talk with your doctor or pharmacist before taking this product.
What side effects might I experience?
Holy basil is generally well tolerated in the short term. In one clinical study, a small number of participants reported nausea or loose stools. Long-term safety data are limited, so if you're taking it for months, that's worth bringing up with your healthcare provider.
Does holy basil actually work for anxiety or other conditions?
We don't have enough reliable evidence yet. The data shows insufficient evidence to rate it for anxiety, asthma, headache, respiratory infections, dental plaque, or diabetes — so we can't say whether it works for these uses based on the studies we hold.
