HelloPharmacist Scorecard of Tulsihills 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 Sep 17, 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 2 active ingredients.
  • “{Holy Basil} Blend” is a proprietary blend — the label gives one combined amount (400 mg) without saying how much of each component you get.

Tulsihills contains 2 active ingredients: holy basil leaves extract and holy basil leaves powder — both forms of the same plant. These provide the herb in concentrated and whole-plant formats.

The capsule also contains inactive ingredients: magnesium stearate, silica, and gelatin as the capsule shell.

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 data we hold shows insufficient reliable evidence to rate holy basil for generalized anxiety disorder, asthma, headache, respiratory tract infections, dental plaque, or diabetes. That doesn't mean it doesn't work — it means the quality or quantity of research we have isn't solid enough yet to make a clear claim.

If you're thinking about it for one of these reasons, that's a 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 short-term in adults, though long-term safety data are limited. The most common side effects from oral use are loose stools and nausea — a small number of trial participants experienced these.

The safety data advises against this product during pregnancy and breastfeeding, so if you're pregnant, planning to become pregnant, or nursing, talk with your doctor or pharmacist before taking it.

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 Tulsihills, check with your doctor or pharmacist if you take antidiabetes drugs (due to risk of low blood sugar), blood thinners or antiplatelet medications (due to bleeding risk), or pentobarbital or other sedatives (due to increased drowsiness). No interactions are documented for the inactive ingredients.

Tulsihills by Herbal Hills: Common Questions

Does Tulsihills by Herbal Hills interact with any medications?
Yes. Based on its ingredients, Tulsihills 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?
Tulsihills 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 Tulsihills if I'm on diabetes medication?
Not without checking first. Holy basil can lower blood glucose, so combined with diabetes medication there's a Moderate risk of low blood sugar (hypoglycemia). Talk with your doctor or pharmacist before adding this — they may want to adjust your diabetes drug or monitor you more closely.
What are the side effects?
The most common are loose stools and nausea from oral use — a small number of trial participants experienced these. Overall, holy basil extract seems well tolerated short-term. Long-term safety data are limited, though.
Is holy basil safe during pregnancy or breastfeeding?
No. The safety data advises against this product during pregnancy and while breastfeeding. If you're pregnant, planning pregnancy, or nursing, talk with your doctor or pharmacist before taking it.
Does Tulsihills actually work for anxiety or asthma?
The evidence we hold shows insufficient reliable data to rate holy basil for those uses. That means research hasn't yet built a strong enough case either way. Ask your doctor or pharmacist whether it makes sense for you.
If I'm on a blood thinner, can I use this?
That's a Moderate-severity interaction to sort out first. Holy basil seed oil may increase bleeding risk with anticoagulant or antiplatelet drugs. Check with your doctor or pharmacist before starting.
What's the difference between the extract and powder forms in this product?
Both are holy basil — the extract is concentrated, the powder is the whole dried leaf. This product contains both. They carry the same interaction risks and safety profile.
