(From bad, and to smell). An ill smell, fetid. Foesius thinks that in Hippocrates it means a.fetid disorder of the small intestines. It is also the name of a malagma for the pleurisy, and of an acopon, which Galen and Paulus describe. Sauvages, and some other nosologists, form a genus of disorder which they name dysodia, and define it to be disagreeable exhalation from the whole body, or from a particular part, the skin, the mouth, or the feet.

Dr. Percival takes notice of a kind of offensive breath, (dysodes pulmonica,) often found in persons with a narrow chest and scorbutic habit. He observes, that it seems to originate from a want of power to make a full expiration, by which too much perspirable matter is retained, and corrupted by stagnation in the vesicles of the lungs. In such cases he hath found the most salutary effects from the use of myrrh and fixed air, internally administered. These antiseptic substances are probably carried to the lungs, and correct the offensive vapour at the same time that they invigorate the smallest ramifications of the bronchiae.
