Datura

Datura stramonium

Solanaceae

Jimsonweed — a roadside nightshade whose tropane alkaloids cause blind, hot, mad, dry delirium. Not a medicine for home use.

Legal to grow as an ornamental in most places. Extremely poisonous. Using it as a hallucinogen is a well-known path to the ICU or the morgue. Some localities restrict sales of seeds.

Parts used: None for self-care. Hospital tropanes only.
Traditional notes: Historical anti-asthma smoke (obsolete, dangerous) · Ritual use in several cultures under specialist control

Harvest: Do not harvest for medicine.

If you grow the ornamental, label it and deadhead. Seeds travel.
Every part is tropane-toxic. This is not a moonflower tea.
Keep it out of children’s reach. The flowers advertise themselves.

Lore

Jimsonweed, named for Jamestown soldiers who ate it and lost a week. Tropane alkaloids: atropine, scopolamine. Witchcraft herbals and emergency rooms share the plant. Do not experiment.

The Herbarium — a teaching catalog, not a clinic. Traditional use is history, not a prescription. USDA 6b dates are a week either way, not a promise. Do not eat, drink, or harvest a plant you cannot name.
