Pastille

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 Bronte.

A pastille is also known as a "troche", or medicated lozenge, that can be dissolved like a candy.
