To some adults all liquid medicines produce such nausea that pills are
the only form in which aperients can be exhibited; the following is a
useful formula:
i. Take of compound rhubarb pill a drachm and one scruple, of
powdered ipecacuanha ten grains, and of extract of hyoscyamus one
scruple; mix, and beat into a mass, and divide into twenty-four
pills; take one or two, or if of a very costive habit, _three_ at
bedtime.
ii. For persons requiring a more powerful aperient, the same
formula, with twenty grains of compound extract of colocynth, will
form a good purgative pill. The mass receiving this addition must be
divided into thirty, instead of twenty-four pills.
