Selenine

Selenine is both a cure and preventative for almost all cancers. The drug derives from a fossil lichen found by the first rocket-expedition to Earth’s Moon in 1975, and has been an unparalleled boon to humanity, defeating one of the most stubbornly cure resistant of maladies as a medicine, and preventing its occurrence as a vaccine.

Unsurprisingly, Selenine is incredibly valuable and extremely popular.
