Dolores Umbridge (possibly) 	1995 	Possibly used this spell non-verbally to force a kissing student couple away from each other, whilst patrolling the corridors of Hogwarts as High Inquisitor.
Mundungus Fletcher (possibly)	1996 	Possibly used this spell non-verbally in 1996 outside the Three Broomsticks, when Harry Potter, angered by Mundungus's plundering of Sirius Black's possessions from 12 Grimmauld Place, grabbed the former by the throat.
Hermione Granger 	2 September, 1997	Used it to force chains to withdraw into the arms of a chair in order to free Mary Cattermole from the Muggle-Born Registration Commission when she, Ron, and Harry infiltrated the Ministry of Magic.

== Behind the scenes ==
* Given its effects, it is possible that Relashio may also be able to act as a counter-spell for incarceration spells, Incarcerous and Incarcifors, similar to Emancipare. Relashio may release a victim from the binding ropes conjured via Incarcerous, while it may also free a victim from the prison transfigured from other items using Incarcifors.
* In the film version Harry Potter and the Deathly Hallows: Part 2, it was Hermione Granger who used this jinx to free the dragon guarding the high-security vaults in Gringotts Banks during the 1998 Break-in of Gringotts Wizarding Bank.
* It is possible that Relashio may be related to Emancipare and Liberare, which are also etymologically derived from Latin for "set free". It is however hypothetical in the case of Emancipare, not only due to its conjectural nature, but that it is also similar to The Disarming Charm. It forces the target to drop what the target is holding. Relashio releases a targets grip, thus may disarm them.
* In Fantastic Beasts: The Crimes of Grindelwald - The Original Screenplay, Newt is not explicitly said to have removed the Zouwu's harness with a spell, but the film adaptation shows this method to have been this spell.
* In Harry Potter: Hogwarts Mystery, the player can learn the Revulsion Jinx by reaching maximum friendship with Fred Weasley, from year six onwards.
== Etymology ==
Probably from the French verb relâcher meaning "to release, to set free", Spanish relajo meaning "to loosen up, to release", or Italian rilascio (pronounced the same way as the spell) meaning "I release".
