This manner of administering medicine is of the greatest importance to the sick; it will frequently give relief when all other applications fail. It is supposed that the use of them is of great antiquity; whether this be true or not, the using them to relieve the sick was certainly a very valuable discovery, and no doubt thousands of lives have been saved by it. The doctors have long been in the practice of directing injections to be given to their patients, but they seem to have no other object in administering them than to cause a movement in the bowels; therefore it was immaterial what they were made of.
According to the plan which I have adopted, there are certain important objects aimed at in the administration of medicines to remove disease, viz: to raise the internal heat, promote perspiration, remove the canker, guard against mortification, and restore the digestion. To accomplish these objects, the medicine necessary to remove the complaint must be applied to that part where the disease is seated; if in the stomach only, by taking the medicine it may be removed; but if in the bowels, the same compound must be administered by injection. Whatever is good to cure disease when taken into the stomach, is likewise good for the same purpose if given by injection, as the grand object is to warm the bowels and remove the canker. In all cases of dysentery, colic, piles, and other complaints where the bowels are badly affected, injections should never be dispensed with. They are perfectly safe in all cases, and better that they be used ten times when not needed, than once neglected when they are. In many violent cases, particularly where there is danger of mortification, patients may be relieved by administering medicine in this way, when there would be no chance in any other. I do, therefore, most seriously advise that these considerations be always borne in mind, and that this important way of giving relief be never neglected where there is any chance for it to do good. In many complaints peculiar to females, they are of great importance in giving relief when properly attended to; for which purpose it is only necessary to repeat what has been before stated - let the remedy be applied with judgment and discretion to that part where the disease is seated.
The common preparation for an injection or clyster is to take a teacupful of strong tea made of No. 3, strain it off when hot, and add half a teaspoonful of No. 2, and a teaspoonful of No. 6, when cool enough to give, add half a teaspoonful of No. 1, and the same quantity of nerve powder. (I now use these in combination, using the tincture of each and have it always ready.) In this way you are up-to-date and the liquid compound that you put in the water is clear and there is but very little trouble in giving it. Get the tincture of Nos. 3, 2, 6, 1 and 7, take of each an amount equivalent in strength to that of the amount of powder directed in the foregoing. This would be about: Comp. Tinct. No 3, 2 drachms; Tinct. No. 2, or Capsicum, 3 grains; No. 6, 60 grains, or teaspoon-ful; No. 1, or Lobelia Tinct., I drachm; No. 7, or Tinct. Valerian, I drachm. Mix.
This mixture should be mixed with a quart of fairly warm water and injected, retained for a few minutes and then passed off. This may be repeated as often as required till relief is obtained.
Many other articles may be used to advantage in the injections; a tea of witch-hazel and red raspberry leaves, either or both together, are very good in many cases. For Canker, tea of either the articles described for this purpose will answer a good purpose and give the best of results. When the Canker is removed, the bowels will be left sore, in which case give injections of witch-hazel or red raspberry leaves tea, with slippery-elm bark. When injections are used to move the bowels only, No. I should be left out. It is always safe to add the nerve powder, and if there are nervous symptoms, it should never be omitted.
