Gelsemine
Gelsemine (C20H22N2O2) is an indole alkaloid isolated from flowering plants of the genus ''Gelsemium sempervirens, Gelsemium'', a plant native to the subtropical and tropical Americas, and southeast Asia, and is a highly toxic compound that acts as a paralytic, exposure to which can result in death. It has generally potent activity as an agonist of the mammalian glycine receptor, the activation of which leads to an inhibitory postsynaptic potential in neurons following chloride ion influx, and systemically, to muscle relaxation of varying intensity and deleterious effect. Despite its danger and toxicity, recent pharmacological research has suggested that the biological activities of this compound may offer opportunities for developing treatments related to xenobiotic or diet-induced oxidative stress, and of anxiety and other conditions, with ongoing research including attempts to identify safer derivatives and analogs to make use of gelsemine's beneficial effects.

Gelsemiaceae
Gelsemiaceae is a family of flowering plants, belonging to the order Gentianales. The family contains only three genera: ''Gelsemium'', ''Mostuea'' and ''Pteleocarpa''. ''Gelsemium'' has three species, one native to Southeast Asia and southern China and two native to Central America, Mexico, and the southeastern United States. The eight species of ''Mostuea'' are native to tropical areas of South America, Africa, and Madagascar. The two genera were formerly classified in the family Loganiaceae.Peter F.

Jasmine
Jasmine ( taxonomic name: ''Jasminum''; , ) is a genus of shrubs and vines in the olive family (Oleaceae). It contains around 200 species native to tropical and warm temperate regions of Eurasia, Africa, and Oceania. Jasmines are widely cultivated for the characteristic fragrance of their flowers. A number of unrelated plants contain the word "jasmine" in their common names (see Other plants called "jasmine"). Description Jasmine can be either deciduous (leaves falling in autumn) or evergreen (green all year round), and can be erect, spreading, or climbing shrubs and vines. Their leaves are borne in opposing or alternating arrangement and can be of simple, trifoliate, or pinnate formation. The flowers are typically around in diameter.
