HelloPharmacist Scorecard of Lobelia by L.A. Naturals

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 20, 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: certified organic fresh lobelia in a liquid form. The product also includes grain alcohol and deionized 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.

L.A. Naturals Lobelia is rated possibly ineffective for smoking cessation based on the evidence we hold.

If you're considering it for that purpose, the data doesn't support its use.

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. You may experience nausea, vomiting, diarrhea, throat irritation, coughing, dizziness, or tremors even at doses as low as 50 mg.

At 600 mg or higher, toxicity becomes a serious risk — symptoms include sweating, rapid heartbeat, convulsions, dangerously low body temperature, low blood pressure, and potentially fatal outcomes. This product is not safe during pregnancy or while breastfeeding because of toxicity concerns and the lack of safety data.

Talk with your doctor or pharmacist before using it if you're pregnant, planning to become pregnant, or nursing.

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, double-check with your doctor or pharmacist before starting L.A. Naturals Lobelia — the product may increase lithium levels and require a dose adjustment.

For any other medications, no interactions are documented in our data for the ingredients we could check.

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 carries a real risk of serious toxicity, especially at higher doses, and the evidence doesn't support its use for smoking cessation. If you take lithium, you'll need to check with your doctor before using this product — your dose may need adjustment.

Avoid it entirely if you're pregnant or breastfeeding. Have a conversation with your doctor or pharmacist about whether this is right for you.

Lobelia by L.A. Naturals: Common Questions

Does Lobelia by L.A. Naturals 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 use this to quit smoking?
The evidence we have rates lobelia as possibly ineffective for smoking cessation, so this product is not supported for that use. Talk with your doctor or pharmacist about proven alternatives.
What side effects should I watch for?
At low doses you may get nausea, vomiting, diarrhea, throat irritation, coughing, dizziness, or tremors — even at 50 mg or less. At 600 mg or higher, toxicity symptoms include sweating, rapid heartbeat, convulsions, very low body temperature, low blood pressure, and potentially fatal effects.
Is it safe during pregnancy or breastfeeding?
No. Lobelia is rated likely unsafe for both pregnancy and breastfeeding because of toxicity concerns and lack of safety data. Do not use this product if you're pregnant, planning to become pregnant, or nursing.
Can I take this with lithium?
Maybe, but not without checking first. Lobelia may reduce how your body clears lithium and raise its levels in your blood. Your doctor may need to lower your lithium dose. Talk with your doctor or pharmacist before you start.
What is lobelia used for in this product?
Lobelia is included for smoking cessation, but the evidence doesn't support its use for that purpose. The data we hold rates it as possibly ineffective.
