induce some pain. The agent should not be used in this active form for its<br />

immediate effects during the pregnant term, as its irritating influence<br />

may be sufficient to produce miscarriage.<br />

Cascara in medium doses is an efficient agent in gastric or intestinal<br />

catarrh. It quickly restores the normal tone of the mucous membranes,<br />

suspending undue secretion <strong>and</strong> acting in perfect harmony with other<br />

measures adopted.<br />

It is a useful remedy in many cases of chronic indigestion <strong>and</strong> in chronic<br />

disease of the liver. It has been used in cirrhosis with the best of results.<br />

It is useful in jaundice with deficient excretion of bile, <strong>and</strong> corrects<br />

catarrh of the bile duct. It is useful in diarrhea, subacute or chronic,<br />

depending on deficient liver action, <strong>and</strong> upon catarrhal <strong>and</strong> atonic<br />

conditions of the intestinal tract.<br />

In 1886 quite an interest was excited by the assertion of Goodwin, of New<br />

York, that cascara was an excellent remedy for rheumatism. Many<br />

experimented with it <strong>and</strong> some reported excellent results, but its use for<br />

this purpose has not been continued. It is, however, of value in the<br />

treatment of those cases where gastric <strong>and</strong> intestinal disorders are<br />

present, given in conjunction with more specific agents.<br />
