Therapy. External. Arnica, in tincture or fomentation, has long been a popular but by no means safe discutient to prevent and discuss inflammatory swellings, and to relieve the soreness of myalgia and the effects of sprains, bruises, and contusions.
Therapy. Asafetida is carminative and antispasmodic, and is a very useful nervine for functional spasmodic affections. It is especially adapted to neurotic individuals subject to hysterical or emotional attacks, usually attended by flatulent distention of the abdomen.
Therapy. In small doses, arnica causes increased perspiration, increased secretion of urine, and an accelerated pulse. Its tonic influence upon the nervous system, and directly upon the heart and circulatory organs, make it a useful remedy indeed.
Action, Medical Uses, and Dosage. This tincture is principally used as a local application to sprains, bruises, wounds, etc., but it may also be used internally in all cases where arnica would be applicable. The dose is from 1 to 30 drops.
