The effects of Coffea cruda have to be considered separately from those of
Coffea tosta, since the roasting converts much of the Coffeine into Coffeone or Methylamine,
which gives to coffee its aroma. But the effects are scarcely distinguishable, and I have not
attempted to keep them strictly apart. The provings of Co/f: c. were made with the raw berries.
Coffea belongs to the same family as China, Ipecacuanha, and like these remedies has many
symptoms of intermittent fever. It has been noticed that coffee-drinkers who do get ague are
more difficult to cure than those who do not drink coffee. The great characteristic of Coffea is
exaltation of the senses and sensibility in general. Sight is improved, fine print can be read
easily; hearing is more acute, and noises are intolerable. The sense of smell is heightened. All
kinds of pains are intolerable; and are accompanied with fear of death. The mental activities are
exalted. Sudden emotions, especially joy, produce dangerous symptoms. Great sensitiveness to
touch or contact. These symptoms will recall Acon. Guernsey places it in the front rank of
remedies for irritability. He compares four others with it, all of which have irritability in high
degree, but have different concomitants: Acon., "fearful and anxious; dreads things"; Aur.,
"suicidal, will thrash around in bed (as females in confinement) as if wishing to injure or kill
- ▸themselves"; Cham.
- ▸, "spiteful, uncivil"; Coff.
- ▸, "wakeful, on the constant move"; Nux v.
- ▸, "sullen,
keeps the eyes shut; doesn't wish to speak or have anything to do with any one." Staph. and

- ▸This quasi-
isopathic action, as Teste truly remarks, is by no means confined to Coffea; dynamisations of
many other drugs being antidotal to secondary effects of the crude substances. Hahnemann
describes the migraine of coffee-drinkers thus: "It comes in the morning after waking, increasing
little by little. The pain becomes intolerable, and sometimes burning, integument of head very
sensitive and painful on slightest touch. Body and mind excessively sensitive. Patients look
exhausted, retire to dark places, close their eyes to avoid light of day; remain seated in an
armchair or stretched on a bed. The least noise or motion excites the pain. They avoid talking,
being talked to, or hearing others talk. The body is colder than usual though no chills are
experienced; the hands and feet are especially cold. They loathe everything, especially food and
drink, on account of a continual sickness at the stomach. If the attack is very violent a vomiting
of mucus takes place, which, however, does not relieve the headache. There are no alvine
discharges. This kind of megrim scarcely ever leaves before evening. If the paroxysm is less
violent, a little strong coffee which was the first cause of such a headache will produce a
temporary palliation of the pain, but the disposition to relapse becomes so much greater. The
attacks come irregularly, every fortnight, or every few weeks, without any apparent cause, and
quite suddenly, so much so that the patient often does not feel a single unpleasant symptom the
evening preceding the attack. Such a headache has never been seen by me except in real coffee-
drinkers." It is well to inquire carefully into the dietary of patients who come complaining of
