The situation of the bladder renders it rather improbable that remedies applied externally directly affect it. It is nevertheless common practice to endeavour to influence it by application to the loins of poultices, blisters, and various other medicaments. Drugs internally administered have great effect upon the bladder, and should be given in bland fluids, as linseed tea, milk, barley-water, etc. Opium and belladonna are found to have the most soothing effect, whether administered in the form of draught or pessaries introduced into the canal.
