Acts powerfully upon the cerebrospinal system, giving rise to two distinct and characteristic conditions, known as convulsive and gangrenous ergotism ; the former resulting directly from nerve poisoning, while the latter is due to secondary blood disorganization, or, as is well maintained, to the power Ergot possesses over the unstriped muscular fiber, producing persistent contraction of the arterial coats, diminishing their caliber, and so reducing their current of blood. This, too, might produce cerebral and spinal anaemia, and thus, also, cause the convulsive form of Ergot poisoning. A full description of these conditions may not be presented here, but sufficient may be gathered from the annexed list of symptoms. To the powerful action of Ergot on the unstriped muscular fiber, also, is due the important effects it displays upon the gravid uterus, exciting contractions thereof, and expelling its contents. To avert such a disaster Secale is often the true homoeopathic remedy, but to give it in parturition, to hasten delivery, as is the practice of the Old School, is simply inexcusable.
