HelloPharmacist Scorecard of Lung Expectorant by Herb Pharm

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

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 7 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (572 mg) without saying how much of each component you get.

Herb Pharm's Lung Expectorant is a liquid blend of 7 active herbal extracts. The main ingredient is a proprietary extract blend whose individual components are listed separately: ginger rhizome, elecampane root, yerba santa aerial parts, usnea lichen, thyme flowering aerial parts, and lobelia aerial parts and seed.

These are combined in a base of cane alcohol, distilled water, and vinegar (the inactive, structural ingredients).

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: Respiratory system support and mucus loosening.
  • We looked for evidence on: Asthma, Bronchitis, Chronic obstructive pulmonary disease (COPD), Common cold, Cough, Laryngitis — and 4 related terms.
  • The closest evidence on file: Elecampane is rated "Insufficient Reliable Evidence To Rate" for Cough (Natural Medicines).
  • Also on file: Usnea is rated "Insufficient Reliable Evidence To Rate" for Cough.
  • Also on file: Thyme is rated "Insufficient Reliable Evidence To Rate" for Bronchitis, Common cold, Cough, Tonsillitis, and more.

The effectiveness evidence for most of the herbs in this product is limited. For ginger, research suggests it may be possibly effective for pregnancy-induced nausea and vomiting and dysmenorrhea (period pain), and possibly effective for osteoarthritis, but possibly ineffective for exercise-related muscle soreness and chemotherapy-related nausea.

For the other herbs—elecampane, yerba santa, usnea, thyme, and lobelia—we hold insufficient reliable evidence to rate their effectiveness for the conditions they're traditionally used for, including cough, bronchitis, and smoking cessation. The evidence simply isn't established in our data.

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 5 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.

Ginger is generally well tolerated at typical food and supplement doses in most healthy adults, though higher doses of 5 grams per day or more increase the risk of side effects. Common mild effects from ginger include abdominal discomfort, heartburn, diarrhea, and a pepper-like irritation in the mouth and throat.

One case of mild arrhythmia (irregular heartbeat) was reported in a trial. Elecampane can cause allergic reactions and stomach upset, and is rated likely unsafe in pregnancy and lactation.

Usnea's main constituent, usnic acid, has been linked to liver damage when taken orally and can cause contact dermatitis and conjunctivitis when applied to skin; it's rated likely unsafe in pregnancy and lactation. Yerba santa and lobelia both lack sufficient safety data in pregnancy and lactation, so medicinal use is best avoided in those times.

Thyme is rated likely safe in pregnancy and lactation when used in food amounts, though medicinal doses have not been fully studied.

Ginger Rhizome Extract14 drug types · 1,007 drugs

Anticoagulant/Antiplatelet Drugs

Ginger may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs. However, research is conflicting.
Laboratory research suggests that ginger inhibits thromboxane synthetase and decreases platelet aggregation. However, this has not been demonstrated unequivocally in humans, with mixed results from clinical trials. Theoretically, excessive amounts of ginger might increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, taking ginger with antidiabetes drugs might increase the risk of hypoglycemia.
Animal and human research suggests that ginger might increase insulin levels and/or decrease blood glucose levels.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Ginger might increase or decrease the levels of CYP3A4 substrates.
In vitro research and some case reports suggest that ginger inhibits CYP3A4 activity. Three case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are CYP3A4 substrates (imatinib, dabrafenib, and crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.
Conversely, other in vitro research suggests that ginger induces CYP3A4 activity, leading to reduced levels of CYP3A4 substrates. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Losartan (Cozaar)

Theoretically, ginger might increase levels of losartan and the risk of hypotension.
In animal research, ginger increased the levels and hypotensive effects of a single dose of losartan. It is not clear if ginger alters the concentration or effects of losartan when taken continuously. Additionally, this interaction has not been shown in humans.

Likelihood Possible Evidence D
Nifedipine (Procardia)

Ginger may have antiplatelet effects and increase the risk of bleeding if used with nifedipine.
Clinical research shows that combined treatment with ginger 1 gram plus nifedipine 10 mg significantly inhibits platelet aggregation when compared to nifedipine or ginger alone.

Likelihood Possible Evidence B
P-Glycoprotein Substrates

Ginger might increase the absorption and blood levels of P-glycoprotein (P-gp) substrates.
In vitro research and case reports suggest that ginger inhibits drug efflux by P-gp, potentially increasing absorption and serum levels of P-gp substrates. Two case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are P-gp substrates (trametinib, crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.

Likelihood Possible Evidence D
Phenprocoumon (Marcoumar, Others)

Ginger might increase the risk of bleeding with phenprocoumon.
Phenprocoumon, a warfarin-related anticoagulant, might increase the international normalized ratio (INR) when taken with ginger. There is one case report of a 76-year-old woman with a stable INR on phenprocoumon that increased to greater than 10 when she began consuming dried ginger and ginger tea.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Ginger might increase the risk of bleeding with warfarin.
Laboratory research suggests that ginger might inhibit thromboxane synthetase and decrease platelet aggregation. In one case report, ginger increased the INR when taken with phenprocoumon, which has similar pharmacological effects as warfarin. In another case report, ginger increased the INR when taken with a combination of warfarin, hydrochlorothiazide, and acetaminophen. A longitudinal analysis suggests that taking ginger increases the risk of bleeding in patients taking warfarin for at least 4 months. However, research in healthy people suggests that ginger has no effect on INR, or the pharmacokinetics or pharmacodynamics of warfarin. Until more is known, monitor INRs closely in patients taking large amounts of ginger.

Likelihood Possible Evidence B
Calcium Channel Blockers

Theoretically, taking ginger with calcium channel blockers might increase the risk of hypotension.
Some animal and in vitro research suggests that ginger has hypotensive and calcium channel-blocking effects. Another animal study shows that concomitant administration of ginger and the calcium channel blocker amlodipine leads to greater reductions in blood pressure when compared with amlodipine alone.

Likelihood Unlikely Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, when taken prior to cyclosporine, ginger might decrease cyclosporine levels.
In an animal model, ginger juice taken 2 hours prior to cyclosporine administration reduced the maximum concentration and area under the curve of cyclosporine by 51% and 40%, respectively. This effect was not observed when ginger juice and cyclosporine were administered at the same time.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, ginger might increase the levels of CYP1A2 substrates.
In vitro research shows that ginger inhibits CYP1A2 activity. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2B6 (Cyp2B6) Substrates

Theoretically, ginger might increase the levels of CYP2B6 substrates.
In vitro research shows that ginger inhibits CYP2B6 activity. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, ginger might increase the levels of CYP2C9 substrates.
In vitro research shows that ginger inhibits CYP2C9 activity. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Metronidazole (Flagyl)

Theoretically, ginger might increase levels of metronidazole.
In an animal model, ginger increased the absorption and plasma half-life of metronidazole. In addition, the elimination rate and clearance of metronidazole was significantly reduced.

Likelihood Possible Evidence D
Ginger Rhizome Extract full monograph & interactions

Thyme Flowering Aerial Parts Extract4 drug types · 379 drugs

Anticholinergic Drugs

Theoretically, concurrent use of anticholinergic drugs and thyme essential oil might reduce the effects of anticholinergic drugs.
In vitro evidence suggests that thyme essential oil and specific essential oil constituents like thymohydroquinone and carvacrol can inhibit acetylcholinesterase (AChE). However, this effect has not been observed in humans.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, thyme leaf extract might have additive effects with anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that thyme leaf extract has antiplatelet effects. However, this effect has not been observed in humans.

Likelihood Possible Evidence D
Cholinergic Drugs

Theoretically, concurrent use of cholinergic drugs and thyme essential oil might cause additive cholinergic effects.
In vitro evidence suggests that thyme essential oil and specific essential oil constituents like thymohydroquinone and carvacrol can inhibit acetylcholinesterase (AChE). However, this effect has not been observed in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, thyme might competitively inhibit the effects of estrogen replacement therapy.
In vitro research shows that thyme has estrogen receptor-binding activity and phytoestrogen content. However, this effect has not been observed in humans.

Lung Expectorant by Herb Pharm: Common Questions

Does Lung Expectorant by Herb Pharm interact with any medications?
Yes. Based on its ingredients, Lung Expectorant has a known interaction with 1,211 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Lung Expectorant contains 7 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 while I'm pregnant?
The safety data here is mixed. Ginger is rated possibly to likely safe in pregnancy and is often used for morning sickness—but check with your doctor first and keep amounts moderate. Elecampane, usnea, yerba santa, and lobelia are all rated likely unsafe or have insufficient safety information in pregnancy, so medicinal use should be avoided unless your doctor approves. Thyme is likely safe in food amounts. Your doctor or pharmacist can help you weigh the risks for your situation.
Can I take this while breastfeeding?
Ginger is rated likely safe while nursing. Thyme is also likely safe in food amounts. Elecampane, usnea, lobelia, and yerba santa all lack adequate safety data or are rated likely unsafe while breastfeeding, so medicinal use is best avoided. Talk with your doctor or pharmacist before taking this product if you're nursing.
What side effects might I notice?
The most common ones come from ginger: abdominal discomfort, heartburn, diarrhea, and a peppery irritation in your mouth and throat, especially at doses above 5 grams a day. Elecampane may cause stomach upset and allergic reactions. Lobelia can cause nausea, vomiting, diarrhea, coughing, dizziness, and throat irritation—even at low doses. Thyme may cause allergic reactions, nausea, vomiting, dizziness, or headache. High doses of any of these can cause more serious effects.
Does this product actually work for cough or bronchitis?
The evidence isn't established in our data. While ginger has some research suggesting it may help with nausea and certain types of pain, the other herbs in this blend—elecampane, thyme, lobelia, usnea, and yerba santa—all lack sufficient reliable evidence for cough or bronchitis. These herbs are traditionally used for those purposes, but we can't say the science backs it up.
Is this safe if I'm on a blood thinner like warfarin?
No—do not take this without checking with your doctor first. Both ginger and thyme in this product carry Moderate-severity interactions with anticoagulants and antiplatelet drugs, and may increase your bleeding risk. Ginger specifically has research showing it can affect how warfarin works in your body. You need a conversation with your pharmacist or doctor before starting.
What does 'Herb Pharm' mean by 'proprietary extract blend'?
A proprietary blend is a mix of ingredients listed by weight but not broken down individually on the label—you don't know exactly how much of each herb is in there. In this product, the individual herb extracts are listed separately below the proprietary blend, so we do know what's in it, just not the exact dose of each one.
