Laxatives—the various salines, aperient spring waters, castor oil, cascara sagrada, aloes and other vegetable cathartics.
Digestives—pepsin, pancreatin, muriatic acid and the various bitter tonics.
Are there any remedies which have a specific influence?
No; although arsenic, in exceptional instances, seems to exert a special action. Cod-liver oil is also of great value in some cases.
Upon the whole the most important remedies are those which keep in view the maintenance of a proper and healthful condition of the gastro-intestinal tract, and especially with regular and rather free action of the bowels.
In what class of cases does arsenic often prove of service?
In the sluggish, dry, erythematous, scaly and papular types.
In what cases is arsenic usually contraindicated?
It should never be employed in acute cases; nor in any instance (unless its action is watched), in which the degree of inflammatory action is marked, as an aggravation of the disease usually results.
What should be the character of the external treatment?
