HelloPharmacist Scorecard of Linden by Herbal Terra

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 Jul 11, 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 and leaf extract in dried form. Linden has been used traditionally as a tea, and this liquid form concentrates that botanical.

The product also contains alcohol, water, and glycerin as inactive ingredients that help preserve and deliver 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.

The evidence on whether linden actually works is not established in the data we hold. There are no effectiveness ratings on file for this ingredient, so we cannot tell you what science shows about its benefits.

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. We have one case report of an allergic reaction to linden pollen in a tea and one report of skin irritation (contact urticaria) from a linden extract shampoo — so allergic reactions are possible, especially if you're sensitive to pollen or botanicals.

Safety hasn't been well studied overall, so check with your doctor before use. There is not enough information on file about linden's safety in pregnancy and lactation to say whether it's okay.

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, check with your doctor or pharmacist before using this product. Linden's diuretic properties may increase lithium's effects and side effects, and your dose might need adjustment.

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 may be worth trying if you're interested in herbal teas and have no drug interactions to worry about. If you take lithium, do not start this without talking to your prescriber first — the interaction is real and your medication dose might need to change.

Talk to your pharmacist about your full medication list before you begin.
