Mirakuru

The Miracle is a serum tested on criminals by Sebastian Blood's organization. It seems that Blood wishes to use it to make criminals into something else, or possibly force them to obey him (hence his statement made to Xavier Reed if he was "ready to serve" before administering him with it).

Its exact properties and intended purpose are unclear, though when Xavier Reed was injected, the needle wound swelled immediately, and his eyes begun to bleed. It remains unclear if Reed survived his exposure.

It is possible that, as Sebastian Blood stated that to fix Starling City, he needed "an army of the strong"; the serum may be intended to give those injected with it a superhuman strength.
