Lobelia Powder
Also known as: Asthma weed, Bladderpod, Eyebright, Gagroot, Indian tobacco, Indian weed, Pukeweed, Vomitwort, *Lobelia inflata*
Overview
*Lobelia inflata* is a flowering plant native to North America, recognized for its historical use in herbal medicine, particularly for respiratory conditions like asthma and bronchitis. The herb contains lobeline, an alkaloid known to interact with nicotinic acetylcholine receptors, suggesting potential applications in smoking cessation. However, research maturity is low, with most evidence based on traditional use and animal studies, highlighting the need for more robust human clinical trials to ascertain its effectiveness and safety in common applications. Due to safety concerns, it is categorized as an herbal supplement generally requiring medical supervision for use.
Benefits
Lobelia may provide potential benefits in reducing respiratory symptoms and aiding in smoking cessation, although clinical evidence remains inconclusive. Some studies suggest it may assist in managing ADHD symptoms and mood disorders; however, these areas lack substantial human research. The variability in outcome and the absence of specific population benefits underscore the necessity for further investigation. The limited effect sizes and lack of clinical significance reported in existing literature reflect the current low quality of the evidence available on its benefits.
How it works
Lobeline, the key active component in lobelia, primarily acts on nicotinic acetylcholine receptors, mimicking nicotine but at a lower potency. This interaction may stimulate respiratory responses and influence central nervous system activity, potentially supporting smoking cessation. However, the specific molecular pathways and absorption characteristics of lobelia remain insufficiently explored, contributing to the need for more detailed pharmacological studies.
Side effects
Lobelia is generally considered unsafe when used without medical supervision due to notable potential adverse effects. Common side effects, occurring in over 5% of users, include nausea, vomiting, tremors, and dizziness. Less common adverse reactions (1-5%) may involve respiratory distress or sensations of choking. Rare but severe side effects (less than 1%) can lead to cardiotoxicity, evidenced by hypotension, tachycardia, or convulsions. There are no well-documented drug interactions, but contraindications exist for use during pregnancy and lactation. Due to the unpredictability of side effects, especially in vulnerable populations like children or the elderly, medical consultation is strongly recommended before use.
Dosage
The appropriate dosage of lobelia is not well established, partly due to the lack of clinical trials. Traditional applications suggest a dose of 100 mg of dry lobelia powder taken up to three times daily; however, toxicity can appear at higher doses, with severe effects beginning between 0.6 to 1 g of leaf, and doses over 4 g being potentially fatal. Due to the unclear absorption and bioavailability, recommendations may vary, and users are advised to seek medical guidance for tailored dosing.
FAQs
