Antidote

The Antidote is the creation of Herbert Friedman and is seen in ObsCure. It's the only known way to fight off the Mortifilia based infection. Its next step is the Mortifilia Supression Pills seen in ObsCure II.

The Antidote
The Antidote was created by Herbert Friedman in an attempt to find a cure for the Mutagenic Stages of the Mortifilia's Infection to save his severely mutated brother, Leonard. Unfortunately, Herbert is killed by Denny Walden, and is never able to successfully finish the Cure, however the Antidote is still useful.

The Antidote can somewhat cure the very early stages of the Mortifilia's infection, but only works if the Infected subject hadn't already been exposed to excessive amounts of sunlight, or begun to mutate. It's similar to a vaccine, and is injected via an Injection gun.

Mortifillia Suppressant Pills
These pills are seen in ObsCure II. They seem to continue to suppress the Negative effects of the Mortifilia. However, Shannon Matthews, for unknown reasons, does not need them as her body has been able to somewhat adapt to the Mortifillia Spores, even allowing her to absorb the spores and maintain her humane appearance. Stan Jones and Kenny Matthews were taking these pills to keep themselves from mutating, but when Kenny ran out, and was unable to obtain anymore, he mutated much worse because of the build up of Spores in his body.

Trivia

 * A document written by Herbert explains that mutated subjects that were injected with the Antidote died due to stress, and that the stress had to be fixed before the cure could successfully work without killing a subject.
 * However, the Antidote works on infected subjects that have yet to mutate, however they have to take the green, and yellow pills that will suppress their infection from reoccurring.
 * A theory could be that the ΔΘГ brotherhood provided the pills to the Leafmore survivors, for they had studied the works of the Friedman and were the ones to cover up the entirity of the incident. They could have been disguised as goverment officials, since they are known to have conection to the goverment and even the local police.
