The Ysalamiri Antidote was an antidote created from the Force-Sensitive creature known as Ysalamiri. When a clone is rapidly grown or accelerated too quickly in a short amount of time, the clone would usually experience Clone Madness, driving the clone insane and very unstable. Other species who experiment on Cloning, all know, that when a clone develops clone madness, they were to either terminate the clone or administer the antidote to the clone to overcome and counter the effects.
The antidote is derived from the Ysalamiri creature, who is known to have a strong Force-Ability, to repel the Force, by creating a stable force bubble and shielding itself from the Force. This was the only known antidote to overcome clone madness, which allowed the clones to be stable and sane enough to successfully be trained within a short amount of time.
When a Ysalamiri antidote is created, it takes on a green liquid, which seems to glow brightly, and tremble tremendously strongly, near the presence of clones who experience the symptoms of Clone madness. A clone experiencing clone madness, would only need one injection of the antidote, and would have to wait a certain period of time (depending on the condition of the clone), until the clone's immune system developed a strong immunity over clone madness, making the clone stable and sane.
