Analeptic radiation
Analeptic radiation was a form of radiation known to be harmful to "a rather pernicious mutagenic pathogen" that inhabited the planet Paan Mokar.

In order for Jonathan Archer to visit Paan Mokar in 2152, Phlox had to bombard his immune system with analeptic radiation in order to protect him from the pathogen while he was on the surface. ()
