Yellow Jessamine (Gelsimium sempervirons)
Yellow jessamine is a perennial evergreen vine found in moist woodlands and thickets from Virginia to Texas and in Mexico and Central America. It is also cultivated elsewhere as an ornamental
vine. The slender, woody stems twine about trees and other objects, sometimes reaching a length of 20 feet and climbing from one tree to another. The opposite, lanceolate to ovate leaves are dark green above and pale beneath. The fragrant yellow, funnelform flowers are borne in axillary or terminal cymes from March to May. The fruit is an elliptical capsule containing many seeds.

It is an unrivalled febrifuge, possessing relaxing and antispasmodic properties. It is very effective in migraine and nervous headaches. It equalizes circulation, promotes perspiration and rectifies various secretions without causing nausea or vomiting. It has been used with great success in neuralgia, toothache, and insomnia.
