Borathium

Borathium is a drug.

In 2368, Toby Russell used borathium on a patient who had died. Beverly Crusher thought Toby Russell might have used morathial or leporazine, although Russell felt the newly created borathium was decades ahead. 

In 2371, Julian Bashir thought about using borathium to treat Bryth if a cycle of morathial and leporazine proved ineffective.
