HelloPharmacist Scorecard of Tulsi/Holy Basil by Global Healing Center

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 Sep 17, 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 liquid contains one active ingredient: organic tulsi (also called holy basil). The product also holds organic vegetable glycerin, triple distilled water, and energized trace minerals as inactive ingredients.

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: stress response and mental well-being support.
  • We looked for evidence on: Stress, Generalized anxiety disorder (GAD), Insomnia, Anxiety, Sleep quality, Emotional resilience.
  • 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 Insomnia, Stress.

The evidence we hold shows insufficient reliable data to rate tulsi for generalized anxiety disorder (GAD), asthma, headache, respiratory tract infections, dental plaque, or diabetes. This doesn't mean it doesn't work — it means high-quality human trials are limited or missing for these uses.

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.

Tulsi appears generally well tolerated short-term in adults, but long-term safety data are sparse. The most common side effects from oral use are loose stools and nausea — a small number of trial participants reported these.

For pregnancy and breastfeeding, the data advises caution. Animal data raise safety concerns and human evidence is not established, so the safety information advises against use during pregnancy and while breastfeeding.

Talk with your doctor or pharmacist for personalized guidance if you're pregnant, planning to become pregnant, or nursing.

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.

Tulsi/Holy Basil is generally well tolerated short-term and may be of interest if you're exploring herbal support for anxiety or other conditions — though evidence for its effectiveness is still limited. If you take blood thinners, diabetes medications, or sedatives, you'll want to confirm with your doctor or pharmacist before adding this.

Same goes if you're pregnant or breastfeeding.

Anticoagulant/Antiplatelet Drugs

Theoretically, holy basil seed oil might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, holy basil might increase the risk of hypoglycemia when taken with antidiabetes drugs.
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.

Tulsi/Holy Basil by Global Healing Center: Common Questions

Does Tulsi/Holy Basil by Global Healing Center interact with any medications?
Yes. Based on its ingredients, Tulsi/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?
Tulsi/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 are the most common side effects?
Loose stools and nausea are the most common when taken by mouth. If you apply it topically (like a mouthwash), a bitter taste is the main side effect reported in trials.
Is this safe to take long-term?
Tulsi is generally well tolerated short-term in adults, but we don't have enough high-quality long-term safety data to say how it performs over months or years. Talk with your pharmacist about your timeline and how to monitor yourself.
Can I take this if I'm pregnant or breastfeeding?
The safety data advises against both. Animal data raise concerns and human safety isn't established. Talk with your doctor or pharmacist before use if you're pregnant, planning to become pregnant, or nursing.
Does tulsi actually work for anxiety or diabetes?
The evidence we hold is insufficient to rate tulsi for either generalized anxiety disorder or diabetes. There's some early clinical work showing it may lower blood sugar in type 2 diabetes, but more rigorous trials are needed.
What's in this liquid besides tulsi?
Organic vegetable glycerin, triple distilled water, and energized trace minerals. These are inactive ingredients that help form and preserve the liquid.
