Rhubarb, it should always be recollected, has an astringent as well as
purgative property, according to the extent of the dose in which it is
administered; the former of which never opposes or interferes with the
energy of the latter, since it only takes effect when the substance is
administered in small doses, or, if given in larger ones, not until it
has ceased to operate as a cathartic. This latter circumstance renders
it particularly eligible in cases of diarrhoea, as it evacuates the
offending matter before it operates as an astringent upon the bowels.
As a purgative it operates mildly, and may be given to the youngest
infant; if from two to twelve months old, from three to six grains; for
children above that age, the dose may range from ten grains to twenty.
Its operation, however, is much quickened by the addition of magnesia;
both of which are more effective when thus united than when given
separately. The following form, in a costive and flatulent state of the
bowels, will be found useful[FN#19]; a tea-spoonful or more may be given
every three or four hours until the desired effect is obtained:--
Powdered rhubarb, half a drachm;
Magnesia, two scruples;
Compound spirits of ammonia, twenty drops;
Dill water, two ounces;
Simple syrup, two drachms.
