HelloPharmacist Scorecard of Fibro-Ease by Earth Friend Herb Co.

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

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 6 active ingredients.

Fibro-Ease contains 6 active ingredients: Elderberry, Lobelia, Couch Grass, White Pond Lily, Sheep Sorrel, and Condurango. The product is formulated as a liquid, which means the herbs are extracted and mixed with alcohol and glycerin as inactive ingredients.

Each herb is traditionally used for different purposes — elderberry is known for immune support, lobelia has been used historically for respiratory concerns, and the others have traditional uses in herbal medicine — though the evidence supporting many of these uses remains limited.

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

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The data we hold does not establish effectiveness for any of the conditions associated with these ingredients. Elderberry has insufficient reliable evidence for hay fever, heart disease, chronic fatigue, COPD, brain function, and respiratory infections.

Lobelia is rated possibly ineffective for smoking cessation. White Pond Lily, Sheep Sorrel, and Condurango are all rated insufficient reliable evidence for their traditional uses, including back pain, cough, wound healing, bronchitis, and cancer.

If you're considering this product for a specific health goal, talk to your pharmacist or doctor about what the evidence actually shows.

The evidence, ingredient by ingredient Elderberry Lobelia Couch Grass White Lily Sorrel Condurango

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 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Elderberry made from ripe, properly cooked fruit is generally well tolerated, though raw or unripe berries and seeds can cause nausea, vomiting, diarrhea, dizziness, and other symptoms due to naturally occurring toxins. A rare case of autoimmune hepatitis has been reported in someone taking elderberry long-term.

Lobelia can be toxic and cause nausea, vomiting, diarrhea, throat irritation, tremors, and dizziness at doses as low as 50 mg; higher doses (600 mg or more) may cause sweating, rapid heartbeat, seizures, low blood pressure, and serious harm. Sheep Sorrel contains oxalates; large or concentrated doses may pose a risk to kidney health.

Couch Grass and White Pond Lily have limited human safety data; White Pond Lily may occasionally cause skin reactions when used topically.

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 6 matched ingredients can interact with medications — Lobelia, Elderberry, Sorrel.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; lithium.
  • For scale: 289 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.

Before you take Fibro-Ease, double-check if you're on immunosuppressant medications, pazopanib (a cancer drug), lithium (a mood stabilizer), blood thinners or antiplatelet drugs like warfarin or aspirin, or fexofenadine (Allegra) for allergies. These are the medication types with documented interactions.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product combines multiple herbs with limited evidence of effectiveness and several significant interactions with common medications. If you take immunosuppressants, lithium, blood thinners, or allergy medications, check with your pharmacist before starting.

Because lobelia can be toxic at even modest doses, dosing accuracy is critical. Talk to your pharmacist about whether this product fits your health needs and medications.

Each ingredient & the kinds of drugs it affects

For each ingredient in Fibro-Ease 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.

Sheep Sorrel3 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
Sheep Sorrel full monograph & interactions

Elderberry2 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.

Likelihood Possible Evidence D
Elderberry full monograph & interactions

Lobelia1 drug type · 1 drug

Lithium

Lobelia is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, lobelia might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Fibro-Ease by Earth Friend Herb Co.: Common Questions

Does Fibro-Ease by Earth Friend Herb Co. interact with any medications?
Yes. Based on its ingredients, Fibro-Ease has a known interaction with 289 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Fibro-Ease contains 6 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.
Is this safe to take during pregnancy?
No — avoid it. Lobelia is rated likely unsafe in pregnancy due to toxicity concerns, and elderberry, couch grass, white pond lily, and condurango all lack enough safety data, so the safest choice is to skip this product and talk with your doctor about alternatives if you're pregnant or planning to be.
What about breastfeeding?
No — avoid it. Lobelia is rated likely unsafe while breastfeeding, and the other ingredients either lack reliable safety data or are advised against due to toxicity risks. Talk with your pharmacist or doctor about what's safe for you and your baby.
Can lobelia really be that toxic?
Yes. Even doses as low as 50 mg can cause nausea, vomiting, diarrhea, dizziness, and throat irritation. At 600 mg or higher, lobelia toxicity can cause sweating, rapid heartbeat, seizures, dangerously low blood pressure, and serious harm. Because dosing accuracy matters so much, you need to know exactly how much lobelia is in each dose of this product.
Does this product actually work for fibromyalgia?
The data we hold doesn't establish that any of its ingredients are effective for fibromyalgia or the conditions they're traditionally used for. Talk to your doctor about proven options for fibromyalgia management.
Why does it contain alcohol?
Alcohol is used as a preservative and solvent to extract the herbs into a liquid form. If you need to avoid alcohol, this product may not be right for you — ask your pharmacist about alcohol-free alternatives.
