St Joachim healing oil
Saints Joaquin (sometimes spelled “Joachim,” pronounced “wal-keem”) and Anne, are the parents of the Virgin Mary. There are no mentions of them in the Bible or Gospels, what we know comes from Catholic legend and the Gospel of James, which is an unsanctioned, apocryphal writing form the second century AD. We do know from scholarship that the Gospel of James was not written by James, the brother of Jesus, despite its claim to be so authored.
The witingst tell the same story, that Mary was promised to Joaquin and Anne by an angel, was consecrated to God, and she remained a virgin all her life.
Naturally, there is plenty of room for scholarly debate about these saints. We have no true primary sources that prove they even existed, but certainly we can agree that Mary had parents. Likewise, we can agree that.
Mary had good, faithful parents who raised her with a love and devotion to God like none other except Jesus Christ Himself.
Joaquin and Anne serve as role models for parents and both deserve to be honored and emulated for their devotion to God and Our Lady Mary, the Mother of God.
Tradition of oils
The tradition of anointing with sacred oil is very old indeed. It is used in sacraments and also as a devotional practice. The sick person is invited to apply oil on the part of their body they want healed but as they do so, they are asked to pray to whomever the oil is dedicated to. The Irish blessings oils do not have miraculous power. It is God who has the power to heal. Applying the oil while praying are important ways for us to express our faith in God’s power. By doing so we place our trust in God.
