HelloPharmacist Scorecard of Tulsi Powder by Herbal Hills

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 1 active ingredient.

Herbal Hills Tulsi Powder is a single-ingredient product — just tulsi powder (also called holy basil). There are no inactive ingredients listed.

Tulsi is an herb traditionally used to support general wellness, particularly for stress and immune function, though the clinical evidence for most uses remains incomplete.

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: respiratory tract health and immune support.
  • We looked for evidence on: Asthma, Respiratory tract infections, Bronchitis, Cough, Airway inflammation.
  • The closest evidence on file: Holy Basil is rated "Insufficient Reliable Evidence To Rate" for Asthma (Natural Medicines).
  • Also on file: Holy Basil is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections.

The evidence we hold on tulsi is marked insufficient for a clear rating across the uses studied — generalized anxiety disorder, asthma, headache, respiratory tract infections, dental plaque, and diabetes. Small studies suggest it may help lower blood sugar in type 2 diabetes, but we don't have enough high-quality data to say it works reliably for any of these purposes.

Talk with your pharmacist or doctor about whether it fits your situation.

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 have limited long-term safety data in humans. The most common side effects reported orally are loose stools and nausea — a small number of trial participants experienced these.

The product facts advise against use during pregnancy and breastfeeding. The pregnancy rating is "possibly unsafe" based on animal data; human safety is not established.

There isn't enough reliable safety information for breastfeeding either. If you're pregnant, planning pregnancy, or nursing, talk with your pharmacist or doctor before taking this.

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 start Herbal Hills Tulsi Powder, double-check if you take anticoagulant or antiplatelet drugs (Moderate risk of increased bleeding), antidiabetes medications (Moderate risk of low blood sugar), or pentobarbital/Nembutal (Moderate risk of increased sedation). If you're on any of these, verify the specifics with your pharmacist or doctor.

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.

Tulsi powder is generally well tolerated short-term and may interest you if you're exploring herbal support for stress or general wellness. However, if you take blood thinners, diabetes medications, or barbiturates like pentobarbital, check your medications with the tool on this page first — the interactions are real enough to watch.

Pregnant and nursing individuals should avoid it. When in doubt, run it by your pharmacist.

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 Powder by Herbal Hills: Common Questions

Does Tulsi Powder by Herbal Hills interact with any medications?
Yes. Based on its ingredients, Tulsi Powder 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 Powder 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 pregnant or breastfeeding?
No — the safety data advises against it. Animal studies raise concerns during pregnancy, and there isn't enough reliable information about breastfeeding. Talk with your pharmacist or doctor for personalized advice.
What are the most common side effects?
Orally, the most common ones reported are loose stools and nausea — though only a small number of people in trials experienced them. Topically (as a mouthwash), it can leave a bitter taste.
Does it actually work for anxiety or diabetes?
The evidence we hold isn't strong enough yet. Small studies hint it may lower blood sugar in type 2 diabetes, but we don't have reliable data to confirm it works well for anxiety, asthma, headaches, or the other uses it's marketed for. Talk with your doctor if you're considering it as part of your treatment plan.
Is tulsi safe to take long-term?
It seems well tolerated in the short term, but we have limited high-quality long-term safety data. If you're thinking about using it regularly, check with your pharmacist or doctor.
What exactly is tulsi?
Tulsi is also called holy basil — an herb with a long history in traditional medicine. This product is the powder form of the whole herb.
