Known Hazards
Many, if not all, species in the genus Lobelia contain a range of piperidine alkaloids, particularly lobeline and lobelanine. If ingested, these can cause a range of symptoms including nausea, vomiting, diarrhoea, salivation, exhaustion and weakness, dilation of pupils, convulsions, and coma. Generally, the degree of toxicity is only moderate and plants are only harmful in larger quantities - indeed several species have medicinal uses and a few are even eaten as wild foods[
