Vrathev zh'Ethre was an Andorian zhen in the 23rd century. She was enrolled as a cadet at Starfleet Academy in 2261 when she contracted an illness related to her parafra (the Andorian analogue to the human adrenal gland). She was treated at Starfleet Medical, and cured by a treatment developed by Doctor David Derubbio. (TOS - The Brave and the Bold, Book One novella: The First Artifact)
