HelloPharmacist Scorecard of Lobelia Herb by Cedar Bear

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 Aug 13, 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 1 active ingredient.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (0.50 mL) without saying how much of each component you get.

This product contains one active ingredient: lobelia. Lobelia is an herb that's been traditionally used for respiratory and other purposes.

The liquid form also includes vegetable glycerin and purified water as inactive ingredients.

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

This is a single-ingredient Lobelia product and its label doesn't state a use — see Lobelia's own graded uses on its monograph.

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

The evidence we hold shows lobelia is possibly ineffective for smoking cessation. That's the only effectiveness rating available for this ingredient in our data.

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. The safety data advises against using it during pregnancy or while breastfeeding due to toxicity concerns and lack of safety information.

At doses as low as 50 mg, lobelia can cause nausea, vomiting, diarrhea, coughing, dizziness, tremors, and throat irritation. At 600 mg or higher, toxicity symptoms include sweating, rapid heart rate, convulsions, low body temperature, dangerously low blood pressure, coma, and death.

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 doctor or pharmacist before starting this product. Your lithium level may rise, and your dose might need to be adjusted.

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.

Because of toxicity concerns and the lack of safety data in pregnancy and breastfeeding, this product is not recommended during those times. If you take lithium, talk with your doctor or pharmacist before starting it—your lithium dose may need adjustment.

Given the narrow margin between an active dose and a toxic one, this is one to discuss with your own healthcare provider before use.

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.
