Weather: If you will observe the weather conditions in sharp climates, such as Minnesota, Massachusetts and Canada, you will find that the cold spells are very intense and that people when exposed, come down with complaints very rapidly and violently.
That is the way the Belladonna and Aconite cases come on, but Gelsemium complaints do not come from, such causes nor appear that way. Its complaints are more insidious and come on with a degree of slowness.
A Gelsemium cold develops as symptoms several days after the exposure, while the Aconite cold comes on a few hours after exposure. The Aconite child exposed during the day in dry, cold weather will have croup before midnight. But in the South diseases are very slow. Like the people themselves, their organs are very slow, and their reaction is slow.
Their colds are not taken from the violent cold, but from getting overheated. Hence, they take colds and fevers of a low malarial type; they have congestive headaches and congestive complaints that do not come on suddenly. When we think of the climate, and consider the people, and the pace of remedies, we see that Gelsemium is a remedy for warm climates, while Aconite is a remedy for colder climates.
Certain acute complaints in the North will be like Aconite, while similar complaints will have symptoms in the warmer climate like Gelsemium The colds and fevers of the mild winters will be more likely to run to this medicine, whereas the colds and fevers of a violent winter will be more likely to run to Belladonna and Aconite
It is true that Aconite has complaints in hot weather, fevers and dysentery of hot weather, but they are different from the complaints of winter.
Gelsemium has been used mostly in acute troubles. In lingering acute troubles and in those resembling the chronic it is very useful, but in chronic miasms it is not the remedy. It is only a short-acting remedy, though slow in its beginning. In this it is like Bryonia. Bryonia complaints come on slowly, and hence it is suitable for fevers coming on in the southern climate, but it also has sudden violent complaints, though not to the extent we find in Belladonna
Complaints: The complaints of Gelsemium are largely congestive. Cerebral hyperemia, determination of blood to the brain and to the spinal cord. The extremities become cold and the head and back become hot. The symptoms are manifested largely through the brain and spinal cord. In connection with brain affections there are convulsions of the extremities, crampings of the fingers and toes and of the muscles of the back.
Coldness of the fingers and toes; sometimes the extremities are icy cold to the knees, while the head is hot and the face purple. During the congestion the face is purple and mottled. The eyes are engorged, the pupils dilated (sometimes contracted), the eyes are in a state of marked congestion with lachrymation and twitching.
The patient feels dazed and talks as if he were delirious; incoherent, stupid, forgetful. It is like this in intermittent fever that gradually develops towards a congestive chill. Great coldness running up the back from the lower part of the spine to the back of the head. Shuddering, as if ice were rubbed up the back.
The pains also extend up the back. With the coldness of the extremities, the very dark red countenance, the dazed condition of the mind, the glassy eyes and dilated pupils, we have the neck drawn back and rigidity of the muscles of the back of the neck, so that the neck cannot be straightened, and there are violent pains up the back and coldness in the spine.
This state would remind one of cerebro-spinal meningitis. Pain in the base of the brain and in the back of the neck. With all states there is a very hot skin and a high temperature, with coldness of the extremities. Sometimes the troubles are ushered in with a violent chill.
