Coffee is used as a stimulant to antidote the effects of narcotic poisons. In opium poisoning its effects are prompt and immediate. A strong decoction is prepared and injected within the rectum, if impossible to administer it per orem.
The late Dr. Brodnax, beginning in 1876, used coffee as a stimulant in the debility of slow fevers, especially in protracted pneumonia with feebleness. He found it in every way superior to whiskey.
He observed that new born infants that kept up a whining cry for days always succumbed ultimately from some one cause or other. He took raw coffee beans, ground them and made a strong tea with which he succeeded in curing the condition in every case in which he used it."

Caffeine
"Caffeine is a direct heart stimulant. It is given to support the heart in extreme feebleness or threatened failure. It is given in conjunction with remedies that are apt to have a depressing effect upon the heart, to sustain it against such depression. In feeble heart from dilatation, valvular insufficiency or fatty degeneration, and in dropsy resulting from the above conditions, with deficient capillary tonus, this agent is an excellent remedy.
In exhaustion from prostrating disease, with weak heart, this agent will exercise a positive influence in the general restoration of the patient, through its strengthening action on the heart.
It is given in some cases of asthma, where there is exhaustion from feebleness of the respiratory nerves.
It is given to dispel the drowsiness common to some individuals after eating a hearty meal. It is a remedy for melancholia, hypochondriasis and despondency.
It is a valuable remedy in general lithemic conditions, as it assists in elimination of urea and uric acid.
The main objection to the use of the remedy in these conditions is its inclination to produce persistent wakefulness. In extreme doses it sometimes producer, a mild form of delirium, with palpitation, general tremor and tinnitus aurium.
It is important in uremic coma, which causes depression of the heart and respiratory functions. It should be given hypodermically, in doses of from one-eighth to one-half a grain. It may be used in conjunction with other active eliminants."
