Boiled sweet

Boiled sweets were a type of confectionery from Earth used on at least two occasions by the Doctor.

Uses

 * To counteract the ill effects of time spillage on Jamie McCrimmon, the Second Doctor gave him one of his striped boiled sweets. When Jamie ate it he immediately felt better. (VD: Vortex of Fear)
 * After healing Amy Pond's wounds from a Saturnyn bite, the Eleventh Doctor popped what appeared to be a humbug into her mouth. (DW: The Vampires of Venice)
 * When Rose Tyler was searching through the Doctor's pockets during one adventure, a packet of boiled sweets was one of the items she found. (NSA: The Price of Paradise)
