Overview
Yellow Jessamine is a beautiful climbing vine native to the southeastern United States, producing fragrant yellow trumpet-shaped flowers. Despite its beauty, ALL parts of this plant are EXTREMELY TOXIC, containing potent alkaloids (gelsemine, gelseminine) that cause respiratory paralysis and death. It is included here SOLELY for educational and safety awareness. NEVER use this plant for any medicinal purpose.
Traditional Use
Yellow Jessamine was used in 19th-century medicine as a sedative and analgesic, primarily by Eclectic physicians who used highly diluted preparations for neuralgia, migraine, and fever. It was listed in the U.S. Pharmacopoeia from 1863 to 1926. However, the therapeutic dose was dangerously close to the lethal dose, making it extremely hazardous. Multiple fatalities occurred from accidental ingestion, including children who ate the flowers or sucked nectar. It is no longer used in conventional or herbal medicine due to its extreme toxicity.
