HelloPharmacist Scorecard of Linden by Hawaii Pharm

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.

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: certified organic Linden extract in a liquid form. Linden is a plant traditionally used as a tea, and this extract is combined with vegetable palm glycerin, pharmaceutical-grade alcohol, and purified Hawaiian water as inactive ingredients.

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 hold no effectiveness data in our records for linden extract, so we cannot tell you whether it works for any particular condition based on the evidence we have on file.

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 extract is generally well tolerated as a tea, but human safety data are limited. The safety profile has not been well studied, so you should check with your doctor before use.

Adverse effects are uncommon—there is one reported case of an allergic reaction to linden pollen in tea and one case of contact irritation (urticaria) from a linden extract shampoo. For pregnancy and breastfeeding, there isn't enough safety information on file, so talk with your doctor or pharmacist for personalized advice.

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 may increase its effects and side effects because of its potential diuretic properties, and your dose may need adjusting.

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.

If you're looking at linden as a traditional herbal extract, you should know the safety data are limited and we have no evidence data on file for its effectiveness. The main caution is lithium—if you take it, your doctor or pharmacist needs to review this product with you first.

Talk it over with them before you start.

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.

There isn't enough safety data to know either way. Talk with your doctor or pharmacist about whether this product is right for you during pregnancy or while breastfeeding—they can give you personalized advice based on your situation.
