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 1 active ingredient: Linden Flower with Bract Extract, a liquid herbal preparation. It also includes cane alcohol and distilled water as inactive ingredients to preserve and deliver the herb.

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 ratings on file for linden flower in our data, so we can't tell you what the evidence shows for its use.

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 as a tea, though human safety data are limited. One person reported an allergic reaction to linden pollen in a tea, and another had a skin reaction (contact urticaria) from a linden extract in shampoo.

Safety hasn't been well studied overall, so talk with your doctor before starting it. We don't have specific pregnancy or breastfeeding safety data on file for linden, so there isn't enough information to know either way.

If you're pregnant, planning to be, or breastfeeding, ask your doctor or pharmacist whether it's right for you.

Side effects, ingredient by ingredient Linden

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 — 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 with your doctor or pharmacist before taking this product if you're on lithium. Because linden may increase lithium's effects and side effects, your dose might need to be adjusted.

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.

Linden flower extract is generally well tolerated, but human safety data are thin and it can interact with lithium. If you take lithium or any other medication, check it against the tool on this page before starting, and talk it over with your doctor or pharmacist.
