If taken as soon as the first blur before the eyes is noticed, or before any pain is felt in the head, _Nux Vomica_ will, in nearly all cases, arrest the disease at once. It may be necessary to take two or three doses at intervals of an hour. Later in the case, though _Nux_ may palliate, it will not cure. If headache with sickness comes on, _Macrotin_ and _Podoph._ should be given in alternation, every half hour, if the symptoms are very severe, and the nausea great; but in a mild case, give it once an hour, lengthening the interval as the symptoms abate. If the feet are cold, as is often the case, putting them into hot water will palliate the symptoms, and not interfere with the medicines. If the head feels hot, apply _hot_ water to it. Never apply cold to the head, when there are any symptoms of congestion, as of fullness of the blood vessels. For Common Headache, If the face is red, and the arteries of the neck and temples throb violently, give _Bell._ If there is paleness and faintness, _Pulsatilla_ is the remedy, especially if the forehead is principally affected. If the pain is mostly in the back of the head, _Nux_ is to be used; if in the front, and is sharp, affecting the eyes, _Aconite_; if at the angles of the forehead, with a sense of pinching, _Arnica_; if a sense of fullness and pressing outwards, or with an enlarged feeling, _Macrotin_; if intermitting or remitting, _Mercurius_; if there is ringing in the ears, _China_. Headache from fright should have _Aconite_. For that kind of _headache_ that often occurs during the prevalence of fevers, and is not unfrequently a premonitory symptom of an attack of fever, I have found _Baptisia_ and _Podophyllin_ to be specifics. I give them alternately, every two hours a dose, until the headache ceases. It often subsides in a few minutes after the first dose of either, though I have sometimes failed with one alone and succeeded in the same cases afterwards with both in alternation. _I have no doubt_ but that they act in many cases, as _Prophylactics_, entirely warding off and preventing fevers, or at least arresting them at the premonitory stage. _Podophyllin_ is a most valuable remedy for headache. Nose Bleed--Epistaxis. If it arises from fullness of the vessels of the head, with throbbing of the temples, redness of the face and eyes, _Belladonna_ is the remedy. If fever is present, _Aconite_ must be alternated with _Bell._ In females or children who have habitual nose-bleed, _Pulsatilla_ and _Podophyllin_ are to be used alternately, night and morning. During the paroxysm of bleeding, _Arnica_ should be used, one dose repeated in a half hour if it continues. If it is produced by over-exertion, _Rhus_ is the proper remedy. If it occurs in the _early stage_ of fever, _Aconite_ and _Bell._; in the latter stage, _Rhus_ and _Phos._ are to be used. _Hamamelis_ will frequently arrest nose-bleed _immediately_ after one or two doses.
