Warning The leaves, seeds, and roots of some plants of the Lobelia genus contain poisonous substances and have caused fatalities in humans and animals when ingested. All plants in the genus may contain toxins and should not be ingested. Sensitivity to a toxin varies with a personís age, weight, physical condition, and individual susceptibility. Children are most vulnerable because of their curiosity and small size. Toxicity can vary in a plant according to season, the plantís different parts, and its stage of growth; and plants can absorb toxic substances, such as herbicides, pesticides, and pollutants from the water, air, and soil.
