HelloPharmacist Scorecard of Lobelia 50 mg by Solaray

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

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: lobelia, 50 mg per capsule. Lobelia is an herb traditionally used for smoking cessation, though the evidence for that use is limited.

The capsule also holds inactive ingredients — ginger, gelatin, and magnesium stearate — which are fillers and capsule material.

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.

Lobelia's effectiveness for smoking cessation is rated as possibly ineffective, meaning the evidence doesn't support its use for that purpose 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 carries real safety concerns. At doses as low as 50 mg — the very dose in this product — it can cause nausea, vomiting, diarrhea, coughing, dizziness, tremors, and throat irritation.

At higher doses (600 mg or more), toxicity can develop, causing sweating, rapid heart rate, convulsions, low body temperature, dangerously low blood pressure, coma, and death. Because of toxicity risks and lack of safety data, lobelia is not advised during pregnancy or while breastfeeding.

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 using this product — lobelia may affect how your body clears lithium and could require a dose change.

Lithium

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.
