Star Trek: The Next Generation
Episode: TNG 123 - Symbiosis

Planet: Brekka. Basically humanoid, this race is known for a wrinkled nose bridge and a natural generation of a bio-electric charge, usable as a weapon-similar to that of the now-extinct Cheronians — making their overall phsysiology highly unique to Starfleet science upon firct contact in 2364. The culture kept its sister world of Ornara in virtual addiction to felicium, a native drug the Brekkians claimed was required to fight off ongoing effects of a plague that was long ago cured. A long-time economic stepchild to Ornara, growing felicium was its lone industry.
