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

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Tulsihills has 2 active ingredients: tulsi extract and tulsi powder, both derived from holy basil. This product contains no 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: respiratory tract health and antioxidant support.
  • We looked for evidence on: Respiratory tract infections, Stress, Generalized anxiety disorder (GAD), immune function, inflammation.
  • 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, Stress.

The evidence we hold doesn't establish that Tulsihills works for any of its common uses. Tulsi extract and powder are promoted for generalized anxiety, asthma, headache, respiratory infections, dental plaque, and diabetes—but all six areas have insufficient reliable evidence to rate how well they actually work.

That doesn't mean they don't; it means the studies so far aren't robust enough to say either way.

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 high-quality long-term safety data are limited. The most common side effects from oral use are loose stools and nausea; in one clinical trial, two out of 24 people taking capsules experienced one of these.

Avoid Tulsihills if you are pregnant or breastfeeding. Animal data raise safety concerns during pregnancy, and there isn't enough reliable information to know it's safe while breastfeeding.

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 taking Tulsihills, check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (like warfarin or aspirin)—holy basil may increase bleeding risk. Also flag diabetes medications and any sedatives, especially pentobarbital, since holy basil can lower blood sugar and enhance sedation.

Check your own medication Run your meds through the checker above

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.

Tulsihills might appeal to you if you're exploring herbal support for anxiety or blood sugar, but the evidence for its effectiveness isn't established yet. It's a real concern if you take blood thinners, diabetes drugs, or the sedative pentobarbital—talk with your doctor or pharmacist before starting it.

Also skip it if you're pregnant or breastfeeding.

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 2 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 Tulsihills if I'm on blood thinners?
Not without checking first. Holy basil may increase your bleeding risk when combined with blood thinners like warfarin or antiplatelet drugs. Talk to your doctor or pharmacist before adding this product.
Will Tulsihills help my anxiety?
The evidence we hold for generalized anxiety disorder is insufficient—we can't say whether it works based on current studies. You'd need to discuss whether it's worth trying with your doctor.
What are the side effects?
Most common are loose stools and nausea when taken by mouth. In one clinical study, a small number of participants taking holy basil capsules experienced one of these. Long-term safety data are limited.
Is it safe to take Tulsihills while pregnant?
No. Animal data raise safety concerns and human safety isn't established, so avoid it during pregnancy.
Can I take Tulsihills if I have diabetes and take medication for it?
Not without talking to your doctor first. Holy basil can lower blood sugar, and combining it with your diabetes drugs raises the risk of low blood sugar (hypoglycemia).
Is Tulsihills safe to use while breastfeeding?
No. There isn't enough reliable safety information, so avoid it while breastfeeding.
