Boiled sweet

Boiled sweets were a type of confectionery from Earth. As stated below the boiled sweet was used to help Jamie McCrimmon feel better, after the effects of time spillage, and was also given to Amelia Pond, shortly after recovering from the wounds of a Saturnynian bite, in both cases the sweets are striped, which suggests that these sweets are both the same kind and may have capabilities of making people feel better. The Doctor has owned sweets prior to this, the Second Doctor, Fourth Doctor, and Eighth Doctor all owned jelly babies. The Tenth Doctor owned an Easter egg.

Uses

 * To counteract the ill effects of time spillage on Jamie McCrimmon, the 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 Saturnynian bite, the Doctor popped what appeared to be a humbug into her mouth. (DW: The Vampires of Venice)
