People for whom Gelsemium is most suited fear losing control. They dislike being disturbed, especially while feverish, when they feel dull, drowsy, and dizzy, but want to be held. Their faces are flushed dark red, with a dull, besotted expression. A general state of mental and physical paralysis, with weakness and an inability to perform, are key symptoms linked to this remedy. At times the remedy has been given to strengthen courage on the battlefield, and it is often used for phobias, exam nerves, stage fright, and other anticipatory terrors, which cause trembling, weakness, diarrhea, and frequent urination. In the long term, these symptoms may lead to more complicated, serious neurological disorders and possibly even paralysis, which the remedy may help. Gelsemium is also used to treat acute influenza or sore throats, with weakness, limp limbs, chills, fever, headaches with double vision, and heavy, drooping eyelids. There may be a lack of thirst, even during fever. In addition, the remedy can be given for hay fever if accompanied by these symptoms. Yellow jessamine came into regular use from the middle of the 19th century; chiefly as a treatment for nervous disorders such as sciatica and neuralgia. In its homeopathic form, Gelsemium is prepared from the fresh root, which is chopped, soaked in alcohol, strained, and diluted to the desired, highly dilute potencies. Homeopathic physicians prescribe dilute solutions of gelsemium for ailments that are accompanied by symptoms like those of gelsemium poisoning. Gelsemium mainly affects the brain and spinal cord, the motor nerves, muscles, eyelids, and mucous membranes. Gelsemium alleviates the following: headaches that intensify with movement or bright light and feel as if there is a tight band around the head; a sore scalp due to nerve inflammation; muscle pain associated with fever nervous disorders, such as multiple sclerosis; uterine pain and painful menstruation; achy right-eye pain; a sore throat with red tonsils, difficulty swallowing and earache; and summer colds. It is given for feverish symptoms, such as a sweaty, flushed face, an unpleasant taste in the mouth, a furred, trembling tongue, twitching muscles that feel cold and tingly, chills with waves of heat along the spine. Gelsemium is also used for fears, such as surgery or going to the dentist, and fear after a shock. All are accompanied by trembling. Overexcitement that causes the heart to miss a beat, drowsiness, and insomnia are also helped by Gelsemium.
