HelloPharmacist Scorecard of Lobelia by Herb Stop

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 1 active ingredient.

Herb Stop Lobelia contains one active ingredient: Lobelia Herb Extract, a liquid preparation of the lobelia plant. The other ingredients are grape alcohol and water, which serve as the liquid base and preservative.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: supports healthy respiratory function.
  • We looked for evidence on: asthma, bronchitis, cough.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence we hold rates lobelia as possibly ineffective for smoking cessation. If you're considering this product to quit smoking, talk with your pharmacist or doctor about approaches with stronger evidence behind them.

The evidence, ingredient by ingredient Lobelia

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Lobelia can be toxic, especially at higher doses, so caution is strongly advised. Common side effects from oral use include nausea, vomiting, diarrhea, coughing, dizziness, tremors, and throat irritation—these have been reported at doses as low as 50 mg.

At doses of 600 mg or higher, lobelia leaf can cause serious toxicity: sweating, rapid heartbeat (tachycardia), seizures, low body temperature, dangerously low blood pressure (hypotension), coma, and death. The safety data advises against use during pregnancy and while breastfeeding due to toxicity concerns and lack of safety data.

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?
  • 1 of the 1 matched ingredient can interact with medications — Lobelia.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 1 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.

If you take lithium, check with your pharmacist before starting this product—lobelia's diuretic effects may raise your lithium level and require a dose adjustment.

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.

If you take lithium, you'll want to check with your pharmacist before starting Herb Stop Lobelia—your dose may need adjustment. Because of lobelia's toxicity risk at higher doses and its limited evidence for smoking cessation, discuss this product with your pharmacist or doctor before using it.

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.
