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 product contains one active ingredient: silver linden (Tilia tomentosa) bud extract. Linden buds have been used traditionally as a calming herbal preparation.

The formula also includes glycerin, ethanol, and purified water as inactive ingredients that help deliver and preserve the extract.

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 Linden product and its label doesn't state a use — see Linden'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.

We don't have effectiveness evidence on file for silver linden in the data we hold. That doesn't mean it doesn't work — it means clinical trial data establishing what it does isn't available in our monograph.

If you're considering it for a specific health goal, ask your pharmacist whether research supports its use for that purpose.

The evidence, ingredient by ingredient Linden

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.

Linden is generally well tolerated, but human safety data are limited. The safety information we have isn't thorough enough, so talk with your doctor before use.

Allergic reactions are rare: we have one case report of an allergic reaction to linden pollen in tea and one report of skin irritation from a linden extract shampoo. There isn't enough safety information on file to evaluate use during pregnancy or breastfeeding — discuss it with your doctor or pharmacist if you're pregnant, trying to conceive, or nursing.

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 — Linden.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 1 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.

Check your medications if you take lithium. Linden may increase its levels and side effects in your body.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Silver linden is a traditional herbal extract that's generally well tolerated, but the safety bar is low and evidence of effectiveness isn't established in our data. If you take lithium, this product isn't a straightforward choice — your prescriber needs to weigh the potential.

Talk with your pharmacist or doctor before starting.

Tilia Tomentosa by UNDA Gemmo: Common Questions

Does Tilia Tomentosa by UNDA Gemmo interact with any medications?
Yes. Based on its ingredients, Tilia Tomentosa has a known interaction with 1 medication. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Tilia Tomentosa 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.
Does linden actually do anything?
We don't have clinical evidence on file to say what linden does. That's not the same as proof it doesn't work — just that the trial data we hold doesn't establish its effectiveness. Ask your pharmacist if research supports what you're hoping it will help with.
Is linden safe to use every day?
Linden is generally well tolerated, but human safety data are limited. Because the research on long-term daily use isn't solid, check with your doctor before you start — especially if you're taking other medications or have any health conditions.
Can I take this while I'm pregnant?
There isn't enough safety information on file to know either way. Talk with your doctor or pharmacist about whether it's right for you during pregnancy — that's a personal medical decision that depends on your full picture.
What are the side effects?
Linden is generally well tolerated with no common side effects documented. We do have one case report of an allergic reaction to linden pollen in tea and one of skin irritation from a linden shampoo, but allergic reactions are rare.
Can I take this with my psychiatric medication?
That depends on what you take. If it's lithium, this product could be a problem — linden may increase how much lithium builds up in your body. Run your exact medication through the checker on this page before you start.
