_Take rhubarb_ (O) _one scruple; ipecacuanha, ten grains;
stomach powder_ (M) _fifteen grains; calomel_ (N) _three grains;
mix them and make it into a draught or bolus, with sugar and
water._
This probably will vomit a few times, and then occasion a few stools;
but as the rhubarb has an astringency as well as cathartic quality, it
will in general, after the purging has gently carried off the acrimony,
act as an astringent; particularly if after the above draught, the
following paragoric is taken.
