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.
