* egg white
* powdered sugar
* lavender oil

These sweet lavender pastilles were once most fashionable among ladies
as a breath freshener after indulging in a little wine. A few drops of
essential oil of lavender were added to well sieved powdered sugar and
mixed thoroughly. It was then bound with sufficient lightly beaten egg
white to form a stiff paste, and small portions shaped into lozenge
shaped pastilles. These were then set aside to dry and harden in a warm
place.

While these pastilles were an emergency social measure, a mouth wash
made from an infusion of sage leaves was much favoured for everyday use,
as was sage toothpaste.
