(from ἀ, neg. and ἐπίσια, to digest.) Indigestion.

Abstemiousness and excess are alike causes of indigestion. An over-dilution of the stomach may in some measure injure its proper tone; and long fasting, by inducing a bad quality in the juices fermented into the stomach, renders it feeble, and generates wind. Hard drinking, and any of the causes of anorexia, also injure digestion.

The columbo root is said to be particularly useful when the stomach is languid, the appetite defective, digestion with difficulty carried on, or when a nausea with flatulence attends. It is prescribed in substance with any grateful aromatic, or infused in Madeira wine, now and then interposing gentle doses of the tincture of rhubarb.

A mixture of mustard-seed with the columbo root is of admirable utility in complaints of this kind; particularly where acidity and flatulence prevail much in the prime via.
