(From gravis, heavy). A Cold. Gravedo imports a load in the head, or the running from the nose, experienced in catarrhus or coryza. Celsus translates Gravedo 3969 by the word gravedo; and Coelius Aurelianus by the words catarrhus adnares. Pliny applies this term to the disease called caros; but it is, properly, that weight or listlessness which accompanies a diminished perspiration, and, as Dr. Cullen observes, is generally a symptom of catarrh.

By a cold is usually understood a sudden check of perspiration, from an improper exposure to cold; the consequences of which are the lesser degrees of a catarrh: in its farther advances it is productive of fever, consumption, and similar disorder.

Persons who easily take cold should use frequently moderate exercise, and such medicines as strengthen the general system; as cold bathing, etc. The disposition to take cold may be lessened, by gradually acquiring the habit of being exposed to sudden changes of heat and cold; but this attempt should be conducted with caution, lest the remedy might prove the source of the disease.

Disorders of this kind, in their early period, are speedily relieved by immersing the feet in cold water, just before going to sleep.
