HelloPharmacist Scorecard of Tulsi Tea Original Caffeine-Free by Organic India

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 3 active ingredients.
  • “Proprietary Organic Blend” is a proprietary blend — the label gives one combined amount (1.80 Gram(s)) without saying how much of each component you get.

This tea contains 3 active ingredients: a proprietary organic blend, Vana Tulsi, and two varieties of holy basil — Rama Tulsi and Krishna Tulsi. Holy basil, also called tulsi, is an herb traditionally used in Ayurvedic medicine.

The product has no other inactive ingredients listed.

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 Holy Basil's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: calming and energizing tea with antioxidants.
  • We looked for evidence on: Stress, Generalized anxiety disorder (GAD), Insomnia, Respiratory tract infections, Relaxation, Immune support — and 2 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 what this tea does isn't established in our data. The holy basil it contains shows insufficient reliable evidence for generalized anxiety, asthma, headache, respiratory tract infections, dental plaque, and diabetes.

That doesn't mean it doesn't work — it means the clinical studies we have aren't strong enough yet to say one way or the other.

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 is generally well tolerated in the short term, but good long-term safety data are limited. The most common side effects from oral use are loose stools and nausea — a small number of people in clinical trials experienced these.

During pregnancy, the safety data advises against it; animal data raise concerns and human safety isn't established. While breastfeeding, there isn't enough reliable safety information either, so avoid it then too.

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 you take this tea, check your medications — especially blood thinners or antiplatelet drugs (moderate risk of increased bleeding), diabetes medications (moderate risk of low blood sugar), and pentobarbital (moderate risk of increased sedation). No interactions are documented for Vana Tulsi, but we couldn't check it.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

If you take blood thinners, diabetes medications, or pentobarbital, talk to your pharmacist before starting this tea. The holy basil in it is generally well tolerated short-term, but long-term safety data are sparse.

If you're pregnant or breastfeeding, skip it for now.

Pentobarbital (Nembutal)

Theoretically, holy basil seed oil might increase the sedative effects of pentobarbital.

How can one product interact with so many drugs?
Tulsi Tea Original Caffeine-Free contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 tea if I'm pregnant or breastfeeding?
No. The safety data advises against it during pregnancy because animal studies raise concerns and human safety hasn't been established. While breastfeeding, there isn't enough reliable safety information either. Talk to your doctor or pharmacist about what's safe for you.
What are the most common side effects?
Loose stools and nausea are the main ones reported with oral holy basil use. A small number of people in clinical trials experienced these. Most people tolerate it well in the short term.
How much of this tea should I drink?
That's not information we have from the product facts. Check the package directions or ask your pharmacist.
Does this tea actually work for anxiety or diabetes?
The evidence isn't there yet. Holy basil shows insufficient reliable evidence for generalized anxiety, diabetes, asthma, headaches, respiratory infections, and dental plaque in our data. That doesn't mean it won't help you — it means we need better studies.
Is this caffeine-free really caffeine-free?
Yes — the name says it right there. It's marketed as caffeine-free, so it shouldn't keep you up at night.
