PREPARATIONS: Tincture Veratri Viridis, Tincture of Veratrum Viride. Dose: from two to ten minims. Specific Veratrum. Dose: from one-tenth to five minims.
Therapy: The characteristic indications for veratrum are found in the onset of pneumonitis in strong men previously healthy and vigorous. In these cases, given in doses of a drop of the tincture every half hour, it will slow the pulse and slowly reduce the temperature after four or five hours. This effect can be continued for a few doses longer, and then the doses should be smaller or given farther apart. The pulse should be slowed, in a case with violent premonitory symptoms, down to the normal beat and held there for awhile, and if the symptoms do not quickly abate, the influence may be continued until a pulse of sixty or fifty-five, or even, in a strong man, fifty beats is reached, if the stomach be not yet irritated.
In pleuritis, in bronchitis, in peritonitis, especially pelvic peritonitis from sepsis; in hepatitis and nephritis and cystitis always at the beginning of the acute stage before much structural change has occurred, it may be given, and will retard and often throw off the attack. It is of value in the earlier stages of meningitis and cerebritis, if given understandingly. If the violent heart action be controlled, the processes of disease and any tendency to convulsive action will be at once restrained. ...
