Homeopathic Materia Medica by Farrington
The symptoms of Plumbum, or lead, may be studied from its main property, that is, its tendency to cause constriction of muscular fibre, both voluntary and involuntary. It will cause this contraction of muscles, and it will also cause contraction of the bloodvessels, because it affects the involuntary or non-striated muscular fibres. The first symptom that usually follows poisoning by lead, whether taken by the stomach in slow doses, as in case of drinking water impregnated with it, or whether by inhalation, as in the case of painters, is lead colic, and this consists of horrible griping cramp-pains, with retraction of the abdominal walls, making the abdomen concave rather than convex. There is understood to be spasm of the recti muscles; as these are contracted, of course they draw the abdominal walls in. Pain radiates in all directions, generally following the course of the nerves, sometimes causing delirium when extending to the brain, dyspnoea when involving the chest, retraction of the testicles when extending in that direction, and violent cramps in the legs when reaching the nerves there. With this colic there is obstinate constipation, and in some cases even stercoraceous vomiting.
This colic is antidoted by ALUMINA, ALUM, PLATINA, OPIUM, NUX VOMICA, or BELLADONNA, and is prevented by alcohol.
Next, the symptoms of Plumbum that are of a paralytic character. The first characteristic symptom here is wrist-drop from paralysis of the extensor muscles of the wrist. This Plumbum has cured when it has arisen from other causes than lead-poisoning. This paralysis extends to other parts of the body, always involving extensor muscles in preference to flexors. There appears on the border of the gums a blue line, known as the gingival line. It is caused by the sulphur that exists in the tartar on the teeth combining with the lead in the bloodvessels, and forming a deposit of insoluble sulphide of lead. As I have said, the paralysis extends and involves other parts of the body, and tl en you have this to characterize it: Paralysis, with atrophy of the aifected parts, hence due to true organic changes. Thus you find Plumbum indicated in paralysis of organic origin ; in paralysis from disease of the spinal cord when that nervous structure has undergone fatty degeneration or sclerosis.
Plumbum suits very nicely that disease known as multiple cerebrospinal sclerosis. It is indicated by this symptom: Tremor, followed by paralysis.
We often find Plumbum indicated in paralysis with contracture.
Progressive muscular atrophy may also call for Plumbum.
Lead tends to produce non-development of the uterus. We may therefore find it indicated in cases of tendency to abortion. The foetus in utero grows, but the muscular fibres of the uterus do not develop in proportion, hence the uterus is no longer able to accommodate the growing foetus and abortion ensues.
Sometimes we find Plumbum indicated in delirium, this delirium alternating with the colic. It is very much like that of BELLADONNA; the patient bites and strikes at those near him, but it differs from that of Belladonna in this: There is tremor of the head and hands, and yellow mucus collects about the mouth and teeth. The delirium, moreover, alternates with colic, which is not the case in Belladonna.
Other cerebral disturbances from lead-poisoning are not common, but still the following may be met with: Insomnia, severe headache, either occipital or frontal, with or without vertigo; noises in ears; disordered vision ; diplopia; amaurosis; contraction of pharynx, though liquids are swallowed in gulps and greedily; mind weak, morose, and sad ; preceded by albuminous urine.
Plumbum has frequently caused epilepsy. The characteristic symptoms which indicate it are these: Almost paralytic heaviness of the legs before the attack, and paralysis and prolonged snoring sleep afterwards. It is especially indicated in convulsions from cerebral sclerosis or tumor.
In constipation you may use Plumbum when there is present the retraction of the abdomen already mentioned, and when there is marked spasm or contraction of the sphincter ani. There is urging to stool, and the patient complains of a sensation as though a string were drawing the anus up into the rectum.
In its action on the kidneys Plumbum produces granular degeneration or cirrhosis of those organs. There is very little dropsy or albuminuria, but a marked tendency to uraemic convulsions.
