HelloPharmacist Scorecard of Mucous Membranes Support Alcohol Free 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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 3 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (1,156 mg) without saying how much of each component you get.

This product has 3 active ingredients in a proprietary blend. Gentian root extract and sheep sorrel herb extract are the named actives; the third is elder berry extract, which we cannot verify for interactions.

The liquid is made with glycerin and water as inactive ingredients. All three are plant extracts in dried form, blended together to support mucous membrane health.

The product is alcohol-free, so it relies on glycerin as the base instead.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Mucous membranes support.
  • We looked for evidence on: Bronchitis, Rhinosinusitis, Respiratory congestion, Sinus congestion, Mucous membrane inflammation.
  • The closest evidence on file: Elderberry is rated "Insufficient Reliable Evidence To Rate" for Rhinosinusitis (Natural Medicines).
  • Also on file: Gentian is rated "Insufficient Reliable Evidence To Rate" for Rhinosinusitis.
  • Also on file: Sorrel is rated "Insufficient Reliable Evidence To Rate" for Bronchitis, Rhinosinusitis.

The evidence for these ingredients is limited. Gentian root has insufficient reliable evidence to rate it for wound healing, obesity, rhinosinusitis, or gastritis.

Sheep sorrel has insufficient reliable evidence for bronchitis, breast cancer, or rhinosinusitis. Elder berry extract effectiveness isn't established in the data we hold.

If you're considering this product for a specific condition, talk with your pharmacist about what evidence exists for your situation.

The evidence, ingredient by ingredient Gentian Sorrel Elderberry

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Gentian root is generally well tolerated in small amounts by healthy adults, but it can upset your stomach and isn't well studied at high doses. In one trial combining gentian with turmeric and ginger, some participants experienced nausea, vomiting, diarrhea, or bloating — six out of 17 discontinued the regimen because of these effects.

Sheep sorrel is generally safe as a food in normal amounts, but it's high in oxalates; concentrated medicinal doses haven't been proven safe and may pose a kidney risk with large intakes. A case of kidney inflammation was reported in a child who consumed wild sorrel.

It may also trigger allergic reactions in people sensitive to weed pollen. Gentian is best avoided during pregnancy, and sorrel should be avoided while breastfeeding in medicinal amounts.

There isn't enough safety data for either during pregnancy or breastfeeding — talk with your doctor or pharmacist for personalized advice.

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?
  • 3 of the 3 matched ingredients can interact with medications — Elderberry, Gentian, Sorrel.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs.
  • For scale: 452 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.

Double-check blood pressure medications (antihypertensives) with gentian — it can lower your BP further. Blood thinners and antiplatelet drugs interact moderately with sorrel.

Fexofenadine (Allegra) and other OATP substrate drugs may become less effective when combined with sorrel.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

If you take blood pressure medications or blood thinners, check with your pharmacist before starting this — both gentian and sorrel can affect how those drugs work. The same goes if you take fexofenadine or other medications absorbed by OATP transporters.

Generally, talk with us before adding any herbal blend to your routine, especially if you're pregnant, breastfeeding, or have kidney concerns.

Ingredients driving the most interactions

Each ingredient & the kinds of drugs it affects

For each ingredient in Mucous Membranes Support Alcohol Free with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Gentian Root Extract, Dry1 drug type · 172 drugs

Antihypertensive Drugs

Theoretically, taking gentian with antihypertensive drugs might increase the risk of hypotension.
In vitro research shows that gentian can cause vasodilation and lower blood pressure.

Likelihood Possible Evidence D

Sheep Sorrel Herb Extract, Dry3 drug types · 169 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, sorrel might cause additive effects and side effects when used with anticoagulant or antiplatelet drugs.
In vitro, sorrel has been shown to inhibit platelet aggregation. However, this effect has not been reported in humans.

Likelihood Possible Evidence D
Fexofenadine (Allegra)

Sorrel might reduce the effectiveness of fexofenadine by reducing its absorption from the gut.
In vitro research shows that an ethanol extract of sorrel inhibits organic anion-transporting polypeptide 1A2 (OATP1A2), which transports fexofenadine from the intestine into cells. In rats, concomitant administration of sorrel extract with fexofenadine reduces oral absorption of fexofenadine and the area under the plasma concentration-time curve (AUC).

Likelihood Likely Evidence D
Organic Anion-Transporting Polypeptide Substrates (Oatp)

Sorrel might reduce the effectiveness of OATP substrates by reducing their absorption from the gut.
In vitro research shows that sorrel inhibits OATP1A2. Theoretically it may inhibit other OATPs. The OATPs are expressed in the small intestine and liver and transport drugs into cells. Inhibition of OATP may reduce the bioavailability of oral drugs that are substrates of OATP.

Likelihood Possible Evidence D

Elder Berry Extract, Dry2 drug types · 121 drugs

Immunosuppressants

Theoretically, elderberry might interfere with immunosuppressant therapy due to its immunostimulant activity.
Elderberry has immunostimulant activity, increasing the production of cytokines, including interleukin and tumor necrosis factor.

Likelihood Possible Evidence B
Pazopanib (Votrient)

Theoretically, elderberry might interact with pazopanib, potentially increasing the risk of adverse effects.
In one case, a 65-year-old patient taking pazopanib for 4 weeks for soft-tissue sarcoma developed severe nausea, loose stools, and elevated alanine transaminase and aspartate transaminase levels and was diagnosed with grade 3 liver injury. The patient reported taking elderberry supplements for 2 years, dose unspecified, and was also taking a multivitamin and a calcium supplement. The patient's symptoms and liver enzyme levels improved upon discontinuation of pazopanib and all supplements. Pazopanib treatment was re-initiated, at a lower dose, with no further evidence of liver injury. It was unclear in this case report if the elderberry supplements were derived from the berry, the flower, or the combination.

Mucous Membranes Support Alcohol Free by Herbal Terra: Common Questions

Does Mucous Membranes Support Alcohol Free by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Mucous Membranes Support Alcohol Free has a known interaction with 452 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Mucous Membranes Support Alcohol Free contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Can I take this if I'm on blood pressure medication?
Not without checking first. Gentian root in this product can theoretically lower your blood pressure, which might make your medication work too well and cause dangerously low readings. Talk with your pharmacist before you start — they'll look at your specific drug and dose.
What stomach side effects might I see?
Gentian and sorrel can both upset your stomach. In one trial, some people taking gentian with other herbs experienced nausea, vomiting, diarrhea, or bloating — enough that they stopped. Sorrel may also cause an unpleasant aftertaste.
Is this safe during pregnancy?
Gentian root should be avoided during pregnancy — there isn't enough safety data. Sorrel may be possibly safe in food amounts, but medicinal doses haven't been proven safe either. Talk with your doctor or pharmacist to decide what's right for you.
What is gentian root supposed to do?
Gentian root is traditionally used to support digestive and mucous membrane health, but the evidence to support these uses is insufficient. We don't have reliable data showing it works for wound healing, obesity, rhinosinusitis, or gastritis.
Can I take this if I'm on a blood thinner like warfarin?
Sorrel in this product may theoretically add to the blood-thinning effects of warfarin or similar drugs, raising your bleeding risk. Check with your pharmacist before using this product — they'll know your specific medication and dose.
What is sheep sorrel supposed to do?
Sorrel is included to support mucous membranes, but the evidence to support this is insufficient for bronchitis, breast cancer, and rhinosinusitis. We don't have reliable data showing it works for those conditions.
