HelloPharmacist Scorecard of Iceland Moss 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.
What’s inside
Full disclosure
This product contains one active ingredient: wildcrafted Iceland Moss (Cetraria islandica) as a dried whole plant liquid extract. Iceland Moss is a lichen — not a true moss — that's been used traditionally as a demulcent (a substance that soothes irritated tissues).
The product also contains menstruum, a liquid used to extract and preserve the active ingredient.
Does it work?
Couldn't assess
We don't hold effectiveness evidence in our data for Iceland Moss for any particular condition. The research on this lichen is limited, so we can't tell you what it's been shown to do or how well it works.
How safe is it?
Well-documented data
Iceland Moss is generally well tolerated for short-term use, though human safety data is sparse and quality varies between products. When taken by mouth, it can cause stomach and digestive tract irritation in some people.
Sensitization (allergic reaction) to Iceland Moss is rare. One important note: Iceland Moss can absorb lead from its growing environment — up to 30 mg/kg of dry weight — so long-term use as a primary food source carries a risk of lead buildup.
The safety information during pregnancy and breastfeeding is not adequate; the data rates it possibly unsafe for both, so it's best avoided unless your doctor has cleared it.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredient we could check. That doesn't mean interactions don't exist elsewhere — talk to your pharmacist about your specific medications before starting this product.
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.
Iceland Moss is generally well tolerated short-term and has no documented medication interactions, but evidence of what it actually does is thin, and pregnancy and breastfeeding safety are concerns. If you're pregnant, breastfeeding, or thinking about long-term use, check with your doctor or pharmacist first.
