ART. III.

SECERNENTIA.

I. Those things which increase the irritative motions, which constitute
secretion, are termed secernentia; which are as various as the glands,
which they stimulate into action.

1. Diaphoretics, as aromatic vegetables, essential oils, ether, volatile
alcali, neutral salts, antimonial preparations, external heat, exercise,
friction, cold water for a time with subsequent warmth, blisters, electric
fluid.

2. Sialagogues, as mercury internally, and pyrethrum externally.

3. Expectorants, as squill, onions, gum ammoniac, seneka root, mucilage:
some of these increase the pulmonary perspiration, and perhaps the
pulmonary mucus.

4. Diuretics, as neutral salts, fixed alcali, balsams, resins, asparagus,
cantharides.

5. Cathartics of the mild kind, as sena, jalap, neutral salts, manna. They
increase the secretions of bile, pancreatic juice, and intestinal mucus.

6. The mucus of the bladder is increased by cantharides, and perhaps by oil
of turpentine.

7. The mucus of the rectum by aloe internally, by clysters and
suppositories externally.

8. The mucus of the cellular membrane is increased by blisters and
sinapisms.

9. The mucus of the nostrils is increased by errhines of the milder kind,
as marum, common snuff.

10. The secretion of tears is increased by volatile salts, the vapour of
onions, by grief, and joy.

11. All those medicines increase the heat of the body, and remove those
pains, which originate from a defect of motion in the vessels, which
perform secretion; as pepper produces a glow on the skin, and balsam of
Peru is said to relieve the flatulent cholic. But these medicines differ
from the preceding class, as they neither induce costiveness nor deep
coloured urine in their usual dose, nor intoxication in any dose.

12. Yet if any of these are used unnecessarily, it is obvious, like the
incitantia, that they must contribute to shorten our lives by sooner
rendering peculiar parts of the system
