HelloPharmacist Scorecard of Lung & Bronchial Formula by Christopher's Original Formulas

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 6 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

This liquid formula contains 6 active ingredients: marshmallow, mullein, lobelia, chickweed, pleurisy root, and lungwort, blended in proportions the maker doesn't disclose. These are traditional respiratory herbs — marshmallow and mullein are often used for throat comfort, lobelia for cough, pleurisy root (also called butterfly weed) for chest symptoms, and chickweed and lungwort as supporting botanicals.

The product also contains inactive ingredients listed as "a base of" — we don't have the full list of those excipients on file.

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: lung and bronchial health support.
  • We looked for evidence on: Asthma, Bronchitis, Cough, Influenza, Pneumonia, Respiratory tract infections — and 4 related terms.
  • The closest evidence on file: Lobelia is rated "Possibly Ineffective" for Smoking cessation (Natural Medicines).
  • Also on file: Mullein is rated "Insufficient Reliable Evidence To Rate" for Bronchitis, Asthma, Cough, Influenza, and more.
  • Also on file: Marshmallow is rated "Insufficient Reliable Evidence To Rate" for ACE inhibitor-induced cough.

The effectiveness evidence for the ingredients in this formula is not established in the data we hold. Marshmallow, mullein, lobelia, and chickweed all carry ratings of insufficient reliable evidence for their traditional uses — including respiratory tract infections, cough, bronchitis, and asthma.

Lobelia for smoking cessation is rated possibly ineffective. Pleurisy root and lungwort have no effectiveness data on file.

The evidence, ingredient by ingredient Marshmallow Mullein Lobelia Chickweed Pleurisy Root Lungwort

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 4 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.

Marshmallow and mullein are generally well tolerated for short-term use, but human safety data are limited for both. Lobelia is the ingredient with the most serious safety concern — it can be toxic at higher doses, causing nausea, vomiting, diarrhea, dizziness, tremors, and at 600 mg or above, serious effects like rapid heart rate, low blood pressure, seizures, and even death; use caution and stay within recommended doses.

Pleurisy root also contains potentially toxic compounds similar to digitalis and should be used cautiously. Mullein topically and pleurisy root topically can cause skin irritation in some people.

Chickweed is generally considered lower-risk for short-term use.

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 4 of the 6 matched ingredients can interact with medications — Lobelia, Pleurisy Root, Mullein, Marshmallow.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; heart-rhythm medications; lithium.
  • For scale: 2,045 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 taking this product, clear it with your doctor or pharmacist if you take digoxin (Lanoxin) — the pleurisy root in this formula carries a major interaction risk for heart toxicity. Also check if you take lithium, diuretics (water pills), estrogen-based hormone therapy, or blood thinners (anticoagulants or antiplatelet drugs), all of which have documented interactions with ingredients here.

The bottom line

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

This product is marketed for lung and bronchial support using traditional herbs, but we don't have evidence the formula works for that purpose. More importantly, if you take digoxin (a heart medication), any diuretic (water pill), lithium (for mood), estrogen therapy, or blood thinners, this product carries real interaction risks — check with your doctor or pharmacist before starting.

Even if you take other medications, run them through the tool on this page first.

Each ingredient & the kinds of drugs it affects

For each ingredient in Lung & Bronchial Formula 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.

Marshmallow3 drug types · 2,040 drugs

Lithium

Theoretically, due to potential diuretic effects, marshmallow might reduce excretion and increase levels of lithium.
Marshmallow is thought to have diuretic properties. To avoid lithium toxicity, the dose of lithium might need to be decreased when used with marshmallow.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, marshmallow flower might have antiplatelet effects.
Animal research suggests that marshmallow flower extract has antiplatelet effects. However, the root and leaf of marshmallow, not the flower, are the plant parts most commonly found in dietary supplements. Theoretically, use of marshmallow flower with anticoagulant/antiplatelet drugs can have additive effects, and might increase the risk for bleeding in some patients.

Likelihood Unlikely Evidence D
Oral Drugs

Theoretically, mucilage in marshmallow might impair absorption of oral drugs.
Marshmallow contains mucilage which can affect oral drug absorption. To avoid changes in absorption, take marshmallow 30-60 minutes after oral medications.

Likelihood Possible Evidence D

Mullein1 drug type · 122 drugs

Anticoagulant/Antiplatelet Drugs

Lab tests on extracts from different parts of common and dense-flowered mullein plants show that they do have some blood-thinning effects, as they increase the time it takes for blood to clot. This is likely due to at least one of the known constituents of muellein, triterpenoid saponins. However, the effects appear to be mild and results have been inconsistent. Extracts from different plant parts have been show to have varying anticoagulant strengths, with water-based ones being more potent than alcohol-based extracts.

Likelihood Unlikely Evidence A

Pleurisy Root3 drug types · 117 drugs

Digoxin (Lanoxin)

Pleurisy root contains digitalis-like cardenolide glycosides. Taking pleurisy root in combination with digoxin could increase the risk of adverse effects and toxicity.

Likelihood Probable Evidence D
Diuretic Drugs

Theoretically, concomitant use of potassium-depleting diuretics and pleurisy root can increase the risk of cardiac glycoside toxicity due to potassium depletion. Some diuretics that can deplete potassium include chlorothiazide (Diuril), chlorthalidone (Thalitone), furosemide (Lasix), hydrochlorothiazide (HCTZ, Hydrodiuril, Microzide), and others.

Likelihood Possible Evidence D
Estrogens

Theoretically, excessive amounts of pleurisy root might interfere with hormone drug therapy.

Likelihood Possible Evidence D

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.

Lung & Bronchial Formula by Christopher's Original Formulas: Common Questions

Does Lung & Bronchial Formula by Christopher's Original Formulas interact with any medications?
Yes. Based on its ingredients, Lung & Bronchial Formula has a known interaction with 2,044 medications, including 1 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Lung & Bronchial Formula 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 while pregnant?
No. Marshmallow, mullein, and pleurisy root are all advised against in pregnancy due to insufficient safety data; lobelia is rated likely unsafe due to toxicity concerns. Chickweed is rated likely safe, and lungwort lacks enough data. Overall, the safety data advise against use during pregnancy — talk with your doctor before considering it.
What about breastfeeding?
The safety data advise against it. Marshmallow, mullein, chickweed, and lungwort all lack enough reliable safety information for breastfeeding. Pleurisy root is rated possibly unsafe while breastfeeding, and lobelia is rated likely unsafe due to toxicity. Talk with your doctor or pharmacist for personalized guidance.
Can I take this at the same time as my other oral medications?
Marshmallow in this formula contains mucilage that might impair absorption of oral drugs. To be safe, take marshmallow at least 30 to 60 minutes after your other oral medications. But also check the tool on this page for interactions with your specific drugs — don't rely on timing alone.
Does this formula actually work for cough or bronchitis?
The evidence isn't established in our data. Mullein, marshmallow, lobelia, and chickweed are all rated as having insufficient reliable evidence for cough, bronchitis, and asthma. Lobelia for smoking cessation is rated possibly ineffective. Talk with your doctor about what the evidence supports for your situation.
What side effects might I notice from this product?
Lobelia can cause nausea, vomiting, diarrhea, dizziness, tremors, and throat irritation, especially at higher doses — these have been reported even at doses as low as 50 mg. Pleurisy root can cause nausea, vomiting, and gastrointestinal upset. Mullein and chickweed may cause skin irritation if you're sensitive to them topically.
Is this formula safe to use long-term?
The safety data emphasize short-term use only for marshmallow and mullein — human safety data for longer use are limited. Pleurisy root contains potentially toxic compounds and should be used cautiously and under guidance. This is not a product to take indefinitely without professional oversight.
