Starch Clyster.
Take jelly of starch, four ounces; linseed oil, half an ounce. Liquify the jelly over a gentle fire, and then mix in the oil.
In the dysentery or bloody flux, this clyster may be administered after every loose stool, to heal the ulcerated intestines and blunt the sharpness of corroding humours. Forty or fifty drops of laudanum may be occasionally added; in which case, it will generally supply the place of the Astringent Clyster.
