IN order to which, I may justly premise, that the _Proximous Cause_ is a _Collection_ of deprav’d _crude Humours_ in the Body: As the _Remote Cause_, is a _Suppression_, or _Irregularity_ in the Course of the _Menstruous Blood_. NOW this _Blood_ flowing to the WOMB, as soon as the _VIRGIN_ is _Mature_; if the _Passages_ are not capacious or patent enough, it _regorges_ to the _Major Veins_, and thence to the very BOWELS; extinguishing the _Heat_, and obstructing the _Vessels_ of the _LIVER_, _SPLEEN_, and _MESENTERY_: From whence proceeds a vicious _Concoction_ and _Sanguification_; and consequently a _Collection of crude Humours_, which excite various _Symptoms_ thro’ all Parts of the Body. And it commonly happens, that an irregular or improper _Way of Living_, especially about the Time of _Puberty_, or in the Time of the _natural Course_, engenders a pituitous and viscid _Blood_; which, together with the aforesaid _Humours_, totally obstructs the _Uterine Vessels_. THIS _Distemper_ is very dangerous, if not timely _cur’d_; because if the _Heart_ be very much affected, and the _Vital Faculty_ quite oppressed with it, the _Patient_ often dies suddenly: Or, otherways, it commonly turns to a _Dropsy_; and, when the _Humours_ fly into the HEAD, it causes a _Frenzy_. NOW as I come gradually to set forth the CURE of this _Distemper_, I shall _First_ observe; that, as various _Diseases_ and _Symptoms_ do concur towards its _Complication_, all _These_ are to be discreetly remov’d by proper _Means_ and _Methods_. But that I may be better understood, _SOME_ are more prudently (perhaps) to be remov’d _singly_; and _OTHERS_, _jointly_: As for Instance, if any one _Symptom_ be more troublesome and dangerous than the _Rest_, it ought to be chiefly regarded above All _others_; and, if not _remov’d_, at least _mitigated_ in the First Place. SECONDLY, That a proper _Regulation_ of DIET and _Regimen_ of BODY, is to be judiciously directed, as another initial necessary _Step_ towards the CURE; which we have hereafter more fully treated of. THIRDLY, That this _Distemper_ is more easily and sooner _cur’d_, in _Spring_ or _Summer_-Time, than in _Autumn_ or _Winter_; because when the proper _Constitution_ of _WEATHER_ and _AIR_ concurs with the _medicinal Means_, more may be done towards effecting its CURE in a _Week_, than otherways can be expected in a _Month_. Wherefore _These_ being premised, the CURE will most rationally depend upon the four following methodical _STEPS_; _viz._ I. THAT the vitious _Humours_ lodged in the _Body_, especially in the _Bowels_, be duly _prepar’d_ for Expurgation, and then effectually _evacuated_. II. THAT the _Intemperature_ and _Obstructions_ of the _VENTRICLE_, _LIVER_, _SPLEEN_, and _WOMB_, be All carefully and regularly removed. III. THAT the _Menstrua_ be duly rectify’d, and physically reduc’d to a _Natural Course_, by the best _Conduct_ of Art and Judgment.
