Plant Family
Apiaceae

Identification

Common names: Water Hemlock. Scientific name: Cicuta maculata. Family: Apiaceae.

Wetland Apiaceae with white umbels and highly toxic roots/stems. Always verify leaf, stem, flower, and growth habit together before forage, browsing, or harvest decisions.

Habitat and Range

Ditches, marshy margins, and wet stream edges. In TN/KY transition farms, localized moisture and disturbance shifts can change where this plant appears year to year.

Requires wet soils in sun to partial shade. Match these site preferences to paddock pressure and rotational timing for practical control or utilization.

Ecological Role

Native wetland species with severe toxic hazard around livestock. Ecological behavior directly impacts pollinator support, forage composition, and long-term weed management labor.

Agricultural and Homestead Value

No forage value; high-priority exclusion species. Practical value depends on livestock class, season, and total feed context rather than one plant in isolation.

Forage and management tags: emergency toxic plant.

Toxicity and Animal Interaction

Toxicity level: Severe toxicity concern. Cicutoxin-containing tissues can cause rapid severe neurologic poisoning. Chemistry context: Cicutoxin is the primary neurotoxic compound..

Animals affected or monitored: goats, cattle, sheep, horses, humans. Symptoms to watch: tremors, seizures, salivation, respiratory distress, collapse.

Veterinary Response Notes

Treat as immediate emergency and contact veterinarian/EMS without delay. If a herd event is active, preserve samples and timeline details for your veterinarian.

Historical and Cultural Uses (Archive Context)

Documented as one of the most dangerous North American toxic plants. Historical references are archival context, not modern treatment protocols.

Historical remedy tags: historical poison record.

Foraging and Cultivation Guidance

Never forage due fatal look-alike risk and severe toxicity.

Do not cultivate; restrict access and remove where feasible.
