HelloPharmacist Scorecard of Lobelia by Red Moon Herbs

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 1 active ingredient.

This product contains one active ingredient: Lobelia Flowering Top and Seed Extract. The liquid is made with water and alcohol 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 rates lobelia as possibly ineffective for smoking cessation. That's the main use it's studied for, and the data doesn't support it working well for that goal.

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 carries real caution — it can be toxic, especially at higher doses. You may experience nausea, vomiting, diarrhea, coughing, dizziness, tremors, and throat irritation even at doses as low as 50 mg.

At 600 mg or higher, toxicity becomes a serious risk, with symptoms including rapid heart rate (tachycardia), dangerously low blood pressure (hypotension), seizures, low body temperature (hypothermia), and in severe cases, coma or death. Avoid lobelia during pregnancy and while breastfeeding — the safety data aren't there, and toxicity concerns make it inadvisable.

Side effects, ingredient by ingredient Lobelia

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 may cause lithium to build up in your body, and your dose might need to change.

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.

Lobelia is a high-risk supplement due to its narrow safety window and toxicity potential. If you take lithium, talk to your pharmacist or doctor before considering it — your lithium dose may be affected.

Given the limited evidence for its use and the adverse-effect profile, most people have safer options to explore.

Lobelia by Red Moon Herbs: Common Questions

Does Lobelia by Red Moon Herbs interact with any medications?
Yes. Based on its ingredients, Lobelia has a known interaction with 1 medication. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Lobelia contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 for smoking cessation?
The evidence rates lobelia as possibly ineffective for quitting smoking. Stronger options exist, and given lobelia's toxicity risk, there's no good reason to try it for that goal.
What are the side effects?
Even low doses can cause nausea, vomiting, diarrhea, coughing, dizziness, tremors, and throat irritation. At higher doses (600 mg or more), toxicity sets in — rapid heart rate, dangerously low blood pressure, seizures, low body temperature, and potentially fatal outcomes.
Is it safe during pregnancy or breastfeeding?
No. The safety data rate it as likely unsafe for both pregnancy and breastfeeding because of toxicity concerns and lack of safety evidence. Don't use it if you're pregnant or nursing.
What's in the liquid besides the active ingredient?
Water and alcohol. Those are the inactive ingredients that make up the liquid base.
Why does it interact with lithium?
Lobelia is thought to act as a diuretic (water pill), which may slow how your body clears lithium. That could cause lithium to accumulate to unsafe levels, so your doctor might need to lower your dose if you take both.
