But where the conical explosive bullets of the twentieth century were of no avail, the poisoned arrows of the natives, dipped in the juice of strophanthus and steeped afterwards in decayed carrion, could succeed.
While strophanthus has been shown not to be a real cardiac tonic like digitalis, still there seems to be a nervous sedative action when it is given by the mouth, and it often does good in these cases. The dose is 5 drops of the tincture, in water, three times a day, after meals.
If the heart shows real disturbance from this reflex cause, the treatment aimed toward it depends on whether the heart action is weak or strong and the circulation poor or good. If the circulation is poor, digitalis in small doses may be needed, either 5 drops of an active tincture twice a day, or 8 or 10 drops once a day. If digitalis is not indicated, strophanthus sometimes is valuable.
There are many, however, who believe that they obtain considerable value from the tincture of strophanthus, and there seems to be no doubt that although strophanthus, given in the form of the tincture and by the mouth, may not increase the muscle power of the heart, it many times acts as a satisfactory cardiac sedative.
Under its action the patient becomes less nervous, the heart often acts more regularly, and the low blood pressure may improve. We should not be quite ready to discard the internal use of the tincture of strophanthus. The tincture of strophanthus readily deteriorates, and the preparation ordered should be known to be a good one.
The leading symptom is tetanic spasm. 5. =Poisons Affecting the Heart.= These kill by sudden shock, syncope, or collapse. They comprise prussic acid, dilute solution of oxalic acid and oxalates, aconite, digitalis, strophanthus, convallaria, and tobacco. 6. =Poisons Acting on the Lungs.= These have for their type carbonic acid gas and coal gas.
Cardiac Tonics: Digiralis, strophanthus, caffein, strychnin. 2. Cardiac Stimulants: Camphor, alcohol, ammonia. 3. Vasodilators: Nitrites, iodids, thyroid extract. 4. Cardiac Nutritives: Iron, calcium. 5. Cardiac Emergency Drugs: Ergot, suprarenal active principle, pituitary active principle, atropin, morphin, and also some of the drugs already mentioned.
Ponting, solemnly, "in your father's body that it hasn't gone for." "How d'you know?" "Why, by the medicines he takes. He's giving himself strophanthus now, for his heart." "I say d'you think my mother knows that?" "It's impossible to say what your mother knows. More than she lets on, I shouldn't be surprised." Mr. Ponting pondered. "It's wonderful how he keeps it up. His dignity, I mean."
Strophanthus is given either in the form of the tincture, or as strophanthin. It has been shown that in neither of these forms, when the drug is administered by the stomach, is the muscle of the heart or the blood vessels much acted on. Compensation could not be restored by strophanthus. In emergencies of serious cardiac failure, strophanthin intravenously has been shown apparently to save life.
Various drugs administered internally, such as quinine, salol, salicylate of iron, and others, have a reputation, more or less deserved, as internal antiseptics. Weakness of the heart, as indicated by the condition of the pulse, is treated by the use of such drugs as digitalis, strophanthus, or strychnin, according to circumstances.
