The "holy oil of sick" is an important part of the Catholic Church's sacrament of Anointing of the Sick. It is also known as the "oil of the infirm" or "oil of the sick". This sacred oil is used by priests to anoint the forehead and hands of those who are seriously ill or in danger of death, in order to bring comfort and spiritual strength. Other synonyms for the holy oil of sick include "chrism of the sick", "blessed oil of the sick", and "oil of the dying". Whatever the name, this oil serves as a powerful symbol of the Church's care and support for those who are struggling with illness or approaching the end of life.
