A
pastille was originally a pill shaped lump of compressed
herbs, which was burnt to release its
medicinal properties. Pastilles were in widest use during the eighteenth century, and have never really made a comeback. Today, "pastille" can also refer to a medicinal
pill or flavored candy, or to any kind of
incense. References to the burning of medicinal pastilles include the short story "Birthmark" by
Nathaniel Hawthorne, the poem "The Laboratory" by
Robert Browning, and the novel
Jane Eyre by
Charlotte Brontë. They are also mentioned in the novel
McTeague by
Frank Norris, when the title character's wife burns them to mask an unpleasant odor in the couple's rooms.
A pastille is also known as a "troche", or medicated lozenge, that can be dissolved like a candy.
