In Volume 5 of The Canon of Medicine: Pharmacopia, Avicenna (980-1037 CE), the most famous physician of the Middle Ages, writes about a mysterious dodecapharmacum healing ointment called The Apostles’ Ointment. The ointment is based on the humoural theory of hot, cold, wet, and dry. According to tradition, each of the Apostles offers one ingredient. The resulting ointment has great medicinal value and according to the Four Gospels, was used by a woman to anoint Jesus at Bethany. Was this woman Mary Magdalene? From what Greek text did Avicenna obtain this formula? Discover these mysteries and the natural healing properties of each of the ingredients through the extraordinary work of Avicenna.
