jimson

Jimson is a common name for jimsonweed, Datura stramonium, a poisonous flowering plant in the nightshade family (Solanaceae). It is also known as thorn apple, though that term often refers to the seed capsule. The plant is native to the Americas but has been introduced and naturalized in many temperate and subtropical regions worldwide.

Description: Datura stramonium is an annual or short‑lived perennial with large, irregularly lobed leaves and white to purple, trumpet‑shaped flowers that open at night. The fruits are spiny capsules (thorn apples) containing many hard seeds. Plants can reach up to about 1–2 meters tall and have a bushy, sprawling habit. All parts are toxic.

Chemistry and effects: The plant contains tropane alkaloids, including atropine, hyoscyamine, and scopolamine, which act as anticholinergic compounds. Ingestion or contact can cause dry mouth, blurred vision, rapid pulse, confusion, and hallucinations; high doses may lead to coma or death. Onset of symptoms is variable and can last many hours.

Uses and safety: Historically, jimsonweed has been used in some traditional medicines and, in some cultures, as a hallucinogen. Accidental poisonings occur, especially in children who mistake seeds or plant parts for edible material, or when ornamental plants are ingested. Modern handling emphasizes avoidance of ingestion and cautious handling.
