Volume II — Special Therapeutics

Drs. W. Rutherford, M. Vignal, and W. J. Dodds, have published in the “British Medical Journal” an exhaustive paper on the action of certain cholagogues on the dog, showing by diagrams the increase or decrease of bile secretion, according to the quantity of the drug, etc., administered. They have also tried on the human body the effect of Euonymin and Iridin, and find that the action is the same as on the dog, namely, a notable increase of bile. They state : —

“ As yet we have four grains of Iridin, made into a pill with confection of roses, and taken at bedtime, a certain remedy for biliousness. It produces no disagreeable sensations, and on awaking in the morning the yellow tongue is found to be clean, and the headache and malaise gone. As Iridin, though a powerful hepatic, is not a powerful stimulant, it is well to give in the morning an ordinary mild saline aperient, such as Pullna water or some other. But Iridin, though an agreeable remedy at the time, leaves a somewhat depressing effect ; and it probably should not be taken oftener than once a week or so.” (In large doses. H.)
