Myrrh (//; from Aramaic, but see § Etymology) is a natural gum or resin extracted from a number of small, thorny tree species of the genus Commiphora. Myrrh resin has been used throughout history as a perfume, incense, and medicine. Myrrh mixed with wine can also be ingested.
Extraction and production
When a tree wound penetrates through the bark and into the sapwood, the tree bleeds a resin. Myrrh gum, like frankincense, is such a resin. When people harvest myrrh, they wound the trees repeatedly to bleed them of the gum. Myrrh gum is waxy and coagulates quickly. After the harvest, the gum becomes hard and glossy. The gum is yellowish and may be either clear or opaque. It darkens deeply as it ages, and white streaks emerge.
Commiphora myrrha is native to parts of Saudi Arabia, Oman, Yemen, Somalia, Eritrea and eastern Ethiopia. Meetiga, the trade-name of Arabian Myrrh, is more brittle and gummy than the Somalian variety and does not have the latter's white markings.
The oleo gum resins of a number of other Commiphora species are also used as perfumes, medicines (such as aromatic wound dressings), and incense ingredients. These myrrh-like resins are known as opopanax, balsam, bdellium, guggul bisabol, and Indian myrrh.
Fragrant "myrrh beads" are made from the crushed seeds of Detarium microcarpum, an unrelated West African tree. These beads are traditionally worn by married women in Mali as multiple strands around the hips.
Liquid myrrh, or stacte, written about by Pliny, was an ingredient of Jewish holy incense, and was formerly greatly valued but cannot now be identified in today's markets.
The word "myrrh" derives from the Aramaic ܡܪܝܪܐ (murr), and Arabic مر (mur)، meaning "bitter". Its name entered the English language from the Hebrew Bible, where it is called mor, מור, and later as a Semitic loanword was used in the Greek myth of Myrrha, and later in the Septuagint; in the Greek language, the related word μύρον (mýron) became a general term for perfume.

In pharmacy, myrrh is used as an antiseptic in mouthwashes, gargles, and toothpastes. Myrrh is currently used in some liniments and healing salves that may be applied to abrasions and other minor skin ailments. Myrrh has also been recommended as an analgesic for toothaches and can be used in liniment for bruises, aches, and sprains.
Myrrh is a common ingredient of tooth powders. Myrrh and borax in tincture can be used as a mouth-wash. A compound tincture, or horse tincture, using myrrh is used in veterinary practice for healing wounds.
Myrrh gum is used for indigestion, ulcers, colds, cough, asthma, lung congestion, arthritis pain, and cancer.
As part of a larger search for anticancer compounds from plants, the researchers obtained extracts from a particular species of myrrh plant (Commiphora myrrha) and tested it against a human breast tumor cell line (MCF-7) known to be resistant to anticancer drugs. Research data indicated that the extract killed all of the cancer cells in laboratory dishes.
Traditional Chinese medicine
In traditional Chinese medicine, myrrh is classified as bitter and spicy, with a neutral temperature. It is said to have special efficacy on the heart, liver, and spleen meridians as well as "blood-moving" powers to purge stagnant blood from the uterus. It is therefore recommended for rheumatic, arthritic, and circulatory problems, and for amenorrhea, dysmenorrhea, menopause, and uterine tumors.
Myrrh's uses are similar to those of frankincense, with which it is often combined in decoctions, liniments and incense. When used in concert, myrrh is "blood-moving" while frankincense moves the Qi, making it more useful for arthritic conditions.
Myrrh is used in Ayurveda and Unani medicine, which ascribe tonic and rejuvenative properties to the resin. It (daindhava) is utilized in many specially processed rasayana formulas in Ayurveda. However, non-rasayana myrrh is contraindicated when kidney dysfunction or stomach pain is apparent or for women who are pregnant or have excessive uterine bleeding.
Mechanisms of action
In an attempt to determine the cause of its effectiveness, researchers examined the individual ingredients of a herbal formula used traditionally by Kuwaiti diabetics to lower blood glucose. Myrrh and aloe gums effectively improved glucose tolerance in both normal and diabetic rats.
Myrrh was shown to produce analgesic effects on mice which were subjected to pain. Researchers at the University of Florence showed that sesquiterpenes furanoeudesma-1,3-diene and curzarene in the myrrh affect opioid receptors in the mouse's brain which influence pain perception.
Myrrh has been shown to lower LDL cholesterol (bad cholesterol) levels as well as to increase the HDL cholesterol (good cholesterol) in various tests on humans done in the past few decades. A 2009 laboratory test showed this same effect on albino rats.
In studies done on mice, myrrh has been shown to have significant inhibiting effects on certain types of cancer. The active constituents of myrrh accredited with this property are sesquiterpenes. These tests were done using the myrrh species Commiphora molmol and were also found to inhibit tumor growth.
Myrrh is mentioned as a rare perfume with intoxicating qualities in several places in the Hebrew Bible. In Genesis 37:25 the Ishmaelite traders to whom Jacob's sons sold Joseph their brother had "camels ... loaded with spices, balm and myrrh" and Exodus 30:23-25 specifies that Moses was to use 500 shekels of liquid myrrh as a core ingredient of the sacred anointing oil.
Myrrh was an ingredient of Ketoret, the consecrated incense used in the First and Second Temples at Jerusalem, as described in the Hebrew Bible and Talmud. An offering was made of the Ketoret on a special incense altar and was an important component of the Temple service. Myrrh is also listed as an ingredient in the holy anointing oil used to anoint the Tabernacle, high priests and kings.
Oil of myrrh is used in Esther 2:12 in a purification ritual for the new queen to King Ahasuerus:
Now when every maid's turn was come to go in to king Ahasuerus, after that she had been twelve months, according to the manner of the women, (for so were the days of their purifications accomplished, to wit, six months with oil of myrrh, and six months with sweet odors, and with other things for the purifying of the women)
Myrrh was traded by camel caravans overland from areas of production in southern Arabia by the Nabataeans to their capital city of Petra, from which it was distributed throughout the Mediterranean region.
Myrrh is mentioned in the New Testament as one of the three gifts, along with gold, frankincense, which the magi "from the East" presented to the Christ Child (Matthew 2:11). Myrrh was also present at Jesus's death and burial. Jesus was offered wine and myrrh before the crucifixion (Mark 15:23). According to John's Gospel, Nicodemus and Joseph of Arimathea brought a 100-pound mixture of myrrh and aloes to wrap Jesus' body (John 19:39).
Matthew records that as Jesus went to the cross, they gave him vinegar to drink mingled with gall: and when he had tasted thereof, he would not drink (Matthew 27:34). Mark described the drink as wine mingled with myrrh (Mark 15:23).
Because of its mention in the New Testament, myrrh is an incense offered during Christian liturgical celebrations (see Thurible). Liquid myrrh is sometimes added to egg tempera in the making of icons.
Myrrh is also used to prepare the sacramental chrism used by many churches of both Eastern and Western rites. In the Middle East, the Eastern Orthodox Church traditionally uses oil scented with myrrh (and other fragrances) to perform the sacrament of chrismation, which is commonly referred to as "receiving the Chrism".
According to the Encyclopedia of Islamic Herbal Medicine, "The Messenger of Allah stated, 'Fumigate your houses with al-shih, murr, and sa'tar.'" The author claims that this use of the word "murr" refers specifically to Commiphora myrrha.
Modern myrrh has long been commented on as coming from a different source to that held in high regard by the ancients, having been superior in some way. Pedanius Dioscorides described the myrrh of the first century AD as most likely to refer to a "species of mimosa", describing it "like the Egyptian thorn". He describes its appearance and leaf structure as "pinnate-winged". The ancient type of myrrh conjectured was noted for possessing a far more delightful odor than the modern. It was noted in 1837 that "The time, perhaps, is not far distant, when, through the spirit of research, the true myrrh-tree will be found".
