HelloPharmacist Scorecard of Maidenhair Fern 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

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 Maidenhair Fern dried herb liquid extract, a concentrated form of the traditional plant. Maidenhair (Adiantum) has been used historically in foods and teas.

The only other ingredient listed is menstruum, which is the liquid used to extract and preserve 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 Maidenhair Fern product and its label doesn't state a use — see Maidenhair Fern'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 hold effectiveness ratings for Maidenhair Fern in our data, so we can't speak to how well it works for any particular condition. The product has been used traditionally, but the modern evidence base isn't established in the information we have.

The evidence, ingredient by ingredient Maidenhair Fern

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Modern safety data on Maidenhair Fern in humans are limited, so caution is warranted. The herb has been traditionally linked to effects on menstruation and the uterus, which is why the safety data advises against it during pregnancy.

There isn't enough safety information to recommend it while breastfeeding either — talk with your doctor or pharmacist about your individual situation.

No interactions are documented in our data for the ingredients we could check. Still, if you take any medications, run them through the checker below — it only takes a moment.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and some safety-information gaps remain.

Maidenhair Fern is a single-ingredient traditional herb with no documented medication interactions. Because modern human safety data are sparse and traditional use suggests effects on the uterus, pregnant and breastfeeding people should skip it or check with their pharmacist first.

If you're curious whether it fits your routine, we're here to help.
