Chap. 3. Of WEAKNESSE.
ALthough Weakness of Strength doth generally comprehend the hinderance of al Actions, Ani∣mal, Vital, and Natural; yet more particularly it comprehends the Vital which are known by a Weak Pulse: yet this Weakness useth to be found in al great Diseases, in which Nature doth yeild or resist the Cause.
Therefore as in Palpitation the Action of the Heart that is Pulsation is depraved, so in Weakness it is diminished.
Which is the same with a Syncope, but it differs in this, In a Syncope it is so little that it is hardly perceived; but in Weakness the Pulse is manifest and not so little.
In this also the Animal Faculty is alwaies offended: Hence comes weak motion without hurt of the Brain, Nerves, or Muscles, but from the defect of Vital Spirits which are not so sufficiently sent to the Head that they may be made Animal.
The immediate Cause of Weakness is Defect of the natural heat and spirits from which the life and strength of the parts do depend.
And this Defect is in every part from the Defect of Vital Spirits, and heat flowing from the heart.
Now the Vital Spirits are Defective, either because they are not bred many; or because they are dissipated after they are Bred, or Corrupted, or Suffocated, as we said in a Syncope, where there is this difference, That in a Syncope the Causes of Defect of Spirits, do suddenly produce their effect; but in Weakness they operate by degrees. And therefore in Syncopes and Leipothymia al the Vital Spirits almost, do suddenly fail, but in this there are fewer then ought to be communicated to every part.
Moreover, When the Natural heat wants not only adventitious heat, but also radical moisture to feed upon: if this moisture be wanting and diminished, the natural heat must be less, and the strength abated.
Now the Causes which hinder the spirits from being Generated, or maketh them disperse themselves, or Corrupt, or Suffocate them, are propounded in the Treatise of a Syn∣cope.
The Diagnosis of this Disease needs no Explication because it is manifest, and the Patients do complain of their Weakness. But the signs of the Causes were Propounded in the Syncope.
The Prognostick depends upon the various disposition of Causes, for as they are greater or less, there is more or less danger.
The Cure of this Disease is to be directed to two things, To the taking away of the Cause, and the Restauration of the Heart and vital spirits.
The Causes are, almost al great Diseases, in which either Nature yeilds to, or resisteth with diffi∣culty, therefore the taking away of the Cause belongs to the Cure of almost al Diseases: which you must take from their proper Chapters.
But the strengthning of the Heart, and restoring of the vital spirits are to be here declared; som∣times to be preferred before the Cure of the Cause, when death seems to be at hand: but we must alwayes take heed least when we encrease the strength we encrease the Cause of the Disease: and therefore in a hot Disease you must use more temperate Cordials, but in a Cold Disease those that are more hot.
First then mix Cordials in his nourishment, as Confectio Alkermes, or Confectio de Hyacyntho in Broths, or with pleasant Wine or Cinnamon Water, if there be great weakness.
Boyl also between two Dishes a piece of a Leg of Mutton, after the skin and fat is taken off, and after that let the Patient drink the Broth, being strained, at one daught. Or,
Take the Flesh of a Capon after the skin and fat is taken away, cut it in pieces, and put it in a glassed Pot well Luted, and set it in Balneo Martae to boyl for five hours, then let the Patient take two or three spoonfuls of the Liquor in all his Broths.
