 "Histologic lesions included mild diffuse neuronal degeneration and cerebellar Purkinje cell loss in all animals with mild multifocal vacuolation of brainstem and cerebral white matter in 1 goat, and myofiber atrophy with perimyseal fibrosis in the goose." \\

-Rhizomes and roots (Gelsemii rhizoma) or its extracted alakloids are formerly used to treat neuralgia, especially of the face and the mouth. "It has been used in cough syrups (to treat whooping cough and asthma) and externally to treat various pains resulting from pressure on a nerve, especially in the spinal cord. It is claimed to be of use against migraine and neurological disorders and bleeding (haemorrhoids and the uters)... The alkaloids  (especially gelsemine) inhibit acetylcholine receptors (especially muscarinic AChR), acetylcholine esterase and the synaptic re-uptake of dopamin, noradrenaline and serotonine. These properties explain the observed antispasmodic, analgesic, hypotonic and sedative activities." \\

 As several complex issues were raised, the use of Gelsemium in behavioral science should undergo some reappraisal. In this field, a possible main critical topic might be the placebo/nocebo response of animals, able to exert biases on anxiety models." \\
