Myrrh is a spice and was used in embalming. It was also sometimes mingled with wine to form an article of drink. Such a drink wss given to our Savior when He was about to be crucified, as a stupefying potion Mark 15:23. Mathew 27:34 refers to it as “gall.” Myrrh symbolizes bitterness, suffering, and affliction.
