Chap. 8. Of Nausea, and Vomiting.
NAusea and Vomiting differ only in degrees, and both are the motion of the Stomach by which it either expelleth or labors to expel things contained therein; therfore Nausea is a desire to Vomit with trouble, and only sending and pewking forth a thin waterish Humor by Salivation: whatsoever troubles the Stomach either in quantity or quality useth to stir that up, when it cannot be voided by reason of the weakness of the Stomach, or the strength of the upper Orifice, or thick∣ness of the Matter, or sliminess.
But Vomiting, which is called in Greek Emetos, or Emesia, is a Depraved motion of the Sto∣mach, which shaketh it, by which the Expulsive Faculty is stirred up by Contraction of the Fibres of the lower part and loosening those in the superior, doth sensibly with a violent Motion throw up∣ward the Matter contained therein, which is troublesom unto it▪ it is called a Depraved Motion both in respect of the Object troubling it, as also in respect of the Motion it self, which is from the bot∣tom of the Stomach to the Mouth of it, turning it, when the natural Motion of the Stomach is Com∣pulsive towards the Guts and the Pylorus.
The Differences of Vomitings are taken from their Causes, which are either External or Inter∣nal; therefore it is Divided first into Natural and Artificial; the Natural again, is either without a Disease, or in the Disease; from whence ariseth a Three-fold Difference, one is called Periodical, another Critical, and another Symptomatical.
Periodical is that which without a Disease, is used for preservation often, from whence we reade in Hippocrates, That the Ancients did Vomit Twice every Month, either at distance, or toge∣ther.
And there are many in our times, who use either every Month, or Week, or Day to Vomit Choller, or Flegm; by which they are Preserved from many Diseases: And this is not proper∣ly a Symptome, because there is no Disease present; but it is rather to be termed a Motion of Na∣ture.
Critical Vomiting often happens in Diseases, and by that the Matter of the Disease, if preparati∣on be first made, is wholsomly Evacuated; either al, by which it is Cured; or in part, by which it is Diminished.
Symptomatical Vomiting comes from Nature provoked and weakned and without ease to the Pa∣tient, because it is not enough, or it is nourished continually with the Matter that maketh the Disease.
Other Differences of Vomitings are taken from the things vomited, for they are either Nourishable or Excrementitious; the first is of Meat, Chylus, or pure or mixed blood: the latter is of Flegm, Chol∣ler, Melancholly, Water, Matter, Worms, and the like.
Artificial Vomiting, generally is whatsoever is from an External Cause: The External Causes, are chiefly Stroaks, Falls, Compression of the lower Belly, Southernly weather, or infectious Air, Poysonous Breath, Stinking Smels, Violent Exercise, Riding, Sayling at Sea, especially in a Southernly wind, beholding or conceiving of some filthy thing: And the like External Causes which provoke Nature, or move the Humors; but especially things taken in have great force, not only vo∣mits called Emetica, and Poysons which we distaste; but also Nourishment either hurtful in their Nature, or hated peculiarly of some; as in Hippocrates, who speaks of one who with eating of Mushromes or Toad-stooles, died Vomiting. The same happened to a Courtier of Antoninus the Emperor, who by eating much mouldy Cheese died Vomiting. The quality of Food wil do the same if it be Fat or Oyly, as also a proposterous order in eating, when moistning and loosning things
