Article, IV. Of Tremor, or Trem∣bling.
This Trembling is a depravation of the Voluntary motion, (by reason of the which the Member elevated and lift up cannot be kept in its own proper situation) arising from the debility and weakness of the faculty of motion.
There is no need of SIGNS: It Differeth from a Convulsion, because in this latter the part is contracted, and so kept; from a Palsie, because that in this the part is seldom or never lifted up, or at least very slowly; from a Palpitation, in regard that in this not the whol Member, but the flesh, and especially the Skin is moved; and the member unmoved, one while falleth down, and again another while is distended and stretched forth; and lastly, it differeth from the Rigor or stifness aforesaid, in regard that it is without any pain.
The CAUSE is a weakness of the moving faculty, which happeneth either by a default in the Animal spirits, or the Nerves.
CURE there is none, if it befal those per∣sons that are in yeers, by reason of the extream imbecillity and weakness of the spirits and the brain; if it happen in a vehement Phrensie, or Melancholy; for then it is caused, either by means of the exsiccation or overgreat drying of the Nerves by a Feaver, or else by reason of a corrupt and depraved quality: if it be here∣ditary, or that it proceed from some fault and disorder in point of diet, especially in such that have the Organs of the Animal faculty ex∣treamly weakened; if the sick person Shrink and Start when he is toucht; in acute Feavers, because that the Nerves are either exsiccated and over dried, or else are pulled and twinged by some depraved and vi∣tiated matter, upon which there followeth a Convulsion. The Cure is more facile and easie, if it proceed from Causes that are evi∣dent. It is doubtful and difficult, if it hap∣pen on the lest side, in regard that then the in∣nat heat of that part is the more easily impaired and made to decay; if it turn into a Convul∣sion, because then the peccant matter assumeth unto it self and worse and more offensive qua∣lity; if it happen to be in a burning Feaver, and that a doting follow thereupon; for then some great and grievous Disease succeedeth, and the strength, and powers of the body are wasted and consumed; if the sick party Shrink and Start when he ••s toucht, for then the Nerves are become over moysten∣ed by the peccant Humor. But when we set about the Cure, (and that there be any hopes of effecting it) it is then to be instituted and prosecuted according to the Nature and dispo∣sition of the several Causes and differences, tou∣ching which we purpose to speak further in the sequel.
The Differences are al of them taken from 〈◊〉〈◊〉 the Causes introducing the same.
I. One is from External Causes, especially such as are Malignant and Narcotick, as (to instance) Quick-Silver, Poysons, opiates, Henbane, the Retention of the Secundines or After-birth, and the suppression of the blood after delivery; al which are to be removed. Another is from Causes Internal, of which we shal speak more in the Second Differ∣ence.
II. Another is from the Scarcity and want of Spirits; which either are not generated and bred in a due and fitting sufficiency, by reason of a cold distemper of the brain, (and in this case, in the Cure thereof the Nature of the Disease it self ought heedfully to be regarded) or else after they are generated they come to be dissipated, wasted, and consumed, by an ex∣cessive, heat an over great Evacuation, and some long continued tedious Diseases: and here we are to deal and do our endeavour by prescribing a fit and convenient Diet.
Another there is from some faults and fay∣lings in the Nerves themselves; which may be, I. A Cold and moist Distemper of the brain; and there are some signs present of a misaffect∣ed brain. The Cure must turn towards, and Eye the Distemper. For those Remedies that are taken inwardly, these following are cheifly commended, VIZ. The Essence of Balm, and stoechas of Arabia. Among the Medicaments that are to be externally administred, these are highly approved of, to wit, the Oyl of the flowers of Trifoyl or the three leaved Grass, vulpinum, or the oyl of a fox, the oyl of pepper the Oyl of castor, &c. 2. A Plethory when some wonted Evacuation is suppressed; & then in this case let a Vein be opened. 3. An Obstruction of those same Nerves, such as we term partial ones, or a stoppage of them but in part, whe∣ther it proceed from thick and gross Humors, or else from Gluttony and sur-charging the sto∣mach, and other such like Causes. See fur∣ther hereof in the subsequent Cure of the Palsie.
