 The holy oil used at unction is not stored in the church like the "myron", but consecrated anew for each individual service.When an Orthodox Christian dies, if he has received the Mystery of Unction and some of the consecrated oil remains, it is poured over his body just before burial.It is also common to bless using oils which have been blessed either with a simple blessing by a priest (or even a venerated monastic), or by contact with some sacred object, such as relics of a saint, or which has been taken from an oil lamp burning in front of a wonderworking icon or some other shrine.
