HelloPharmacist Scorecard of Usnea Lichen Moss Strawberry Flavor by TerraVita

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: Usnea Lichen Moss Glycerite Liquid Extract. Usnea is a lichen, and this extract is prepared in glycerin, which acts as both a preservative and a delivery form.

The product also has glycerin and strawberry flavor as inactive ingredients to make it palatable.

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 Usnea product and its label doesn't state a use — see Usnea'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 for usnea isn't established in the data we hold. For cough, obesity, acute pain, wound healing, and tinea pedis (athlete's foot), we have insufficient reliable evidence to rate how well it works.

If you're considering this for one of those uses, that's a conversation worth having with your pharmacist or doctor about what the science actually supports.

The evidence, ingredient by ingredient Usnea

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.

Here's where you need to pay attention: oral usnea may be unsafe. The active compound in usnea — usnic acid — has been linked to liver damage when taken by mouth.

Topically (on the skin) usnea is generally well tolerated, but it can still cause contact dermatitis, conjunctivitis (eye irritation), and allergic reactions with respiratory symptoms in some people. The safety data advises against use during pregnancy and while breastfeeding.

There simply isn't enough information to know it's safe in those situations.

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented for the ingredient we could check.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.

This is a product where the interaction picture is clear — no documented drug interactions — but the safety concern is about the ingredient itself when taken orally. If you're thinking about using it, have a conversation with your pharmacist first about whether oral use is right for you, especially given the liver safety signal with usnic acid.

Usnea Lichen Moss Strawberry Flavor by TerraVita: Common Questions

Does Usnea Lichen Moss Strawberry Flavor by TerraVita interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Usnea Lichen Moss Strawberry Flavor. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Usnea Lichen Moss Strawberry Flavor contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
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.
Is this safe to take by mouth?
Oral usnea may be unsafe; usnic acid, its active compound, has been linked to liver damage. Usnea is generally better tolerated when applied to the skin. Talk to your pharmacist before taking this by mouth.
Can I use this while pregnant or breastfeeding?
The safety data advises against it. There isn't enough information to know it's safe during pregnancy or while breastfeeding. Talk with your doctor or pharmacist for personalized advice.
Does this really work for cough, pain, or wound healing?
We don't have reliable evidence that it does. For cough, pain, wound healing, obesity, and athlete's foot, the evidence is insufficient to rate how well usnea works.
What if I use it on my skin instead of swallowing it?
Topically, usnea is generally well tolerated. However, it can still cause contact dermatitis, eye irritation, and allergic reactions in some people, so a patch test first is smart.
Does this interact with any of my medications?
No interactions are documented in our data for usnea. That said, if you take any prescription or over-the-counter drugs, it's worth a quick check with your pharmacist just to be sure.
