Introduction and Description

Gelsemium sempervirens belongs to the family Loganiaceae. It grows in the piedmont and coastal areas of the southeastern U.S. It is an early flowering climbing vine. The flowers are yellow, funnel shaped, and have a strong odor. The roots and rhizome of yellow jessamine were historically used to treat migraine headaches and types of neuralgia.

Toxicity

All parts of G. sempervirens are toxic, including the flower and nectar. The primary toxic compounds are gelsemine and gelseminine, which act as motor nerve depressants. Symptoms of toxicity in humans include difficulty in use of voluntary muscles, muscle rigidity and weaknes, diziness, loss of speech, dry mouth, visual disturbances, trembling of extremities, profuse sweating, respiratory depression, and convulsions. In Germany, human therapeutic use of the rhizome is not permitted, because it is not believed that efficacy has been adequately documented and serious risks are known. In some Australian states, the use of G. sempervirens is restricted and subject to poison control. The therapeutic dose in humans and the toxic dose are very close. No data could be found regarding livestock toxicity. However, many ergot alkaloids are known to be toxic to livestock.

Uses and Efficacy

It has been claimed that G. sempervirens can be used to treat several types of ailments. However, there is little substantial proof. There are some testimonials regarding its effectiveness in treating various ailments in cats (e.g., fever with shivering, muscle weakness, and vertigo). The doses used were: 30cc BID for 2 days and 3 doses of 30cc 12 hrs apart.
