HelloPharmacist Scorecard of Linden Flower 500 mg by Swanson Premium Brand

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 Aug 13, 2026

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: linden flower, at 500 mg per capsule. Linden has been used traditionally as a tea and is thought to have mild diuretic properties.

The capsule also contains inactive ingredients—gelatin, rice extract blend, stearic acid, and silica—which serve as the capsule shell and flow agents.

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. The evidence supporting its use isn't established in the data we hold.

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, but human safety data are limited, and safety is not well studied. We'd recommend checking with your doctor before use.

Allergic reactions are rare—there's one reported case of an allergic response to linden pollen in linden flower tea, and one case of skin irritation from a linden extract in shampoo. We don't have enough safety information for pregnancy or breastfeeding.

If you're pregnant, nursing, or planning to become pregnant, talk with your doctor or pharmacist before taking this product.

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.

If you take lithium, do not start this product without talking to your doctor or pharmacist first—linden's diuretic properties may increase lithium's effects and side effects, and your dose may need adjustment. No other interactions are documented for the ingredients we could check.

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 may appeal to you if you're interested in traditional herbal support, but human safety data are sparse and we lack solid evidence of effectiveness. If you take lithium, you'll need to check with your doctor before adding this product.

For any other medications or health concerns, run them through the tool on this page and talk it over with your own doctor or pharmacist.
