In all cases of pruritus, except from parasites, much benefit can be derived from washing the parts two or three times daily in a weak solution of bicarbonate of sodium (half a tablespoonful in a quart of water, with a tablespoonful of eau de Cologne).
In pruritus from diabetes some relief may be afforded by the administration of alkaline mineral waters or salicylate of sodium. In pruritus associated with chronic cystitis the last-named remedy is very useful.
