Collinsonia Canadensis. (Stone Root.)
We employ an alcoholic fluid extract of the Collinsonia, representing the crude article ounce for ounce. As there are a great many imperfect preparations in the market, I would advise that it be procured from one of our own houses in this city.
Collinsonia is a specific in ministers' sore throat; administered in the proportion of: Rx Fluid Extract of Collinsonia, Simple Syrup, aa., half teaspoonful to a teaspoonful four times a day.
It proves beneficial in other cases of chronic laryngitis, in chronic bronchitis, and phthisis, allaying irritation, and checking cough.
It also exerts a favorable influence upon the digestive processes, improving the appetite, facilitating digestion, and acting as a general tonic.
It passes off through the kidneys, and exerts a tonic influence upon the entire extent of the urinary tract.
I have thought that its influence was specially exerted upon and through the pneumogastric, relieving irritation of, and giving strength to parts supplied from this source.
Collinsonia is a specific in the early stages of hemorrhoids, and will sometimes effect a cure in the advanced stages of the disease. In this case it is employed in small doses: Fluid Extract of Collinsonia, ʒj.; Water, ℥iv.; a teaspoonful four times a day.
I have given the therapeutics of Collinsonia thus briefly, that the points named might make the greater impression upon the reader. I regard it as one of the most direct and valuable agents of the Materia Medica, and one that will give satisfaction to whoever employs it.
