Myrrh

Myrrh is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Myrrh rather than just read about it. In short: Myrrh (, MUR; from an unidentified ancient Semitic language, مر; from Arabic, מוֹר /mor/; from Hebrew, see § Etymology) is a gum-resin extracted from a few small, thorny tree species of the Commiphora genus, belonging to the Burseraceae family. Myrrh resin was traded in the ancient world, and has been used throughout history in medicine, in ritual, and to make perfume and incense.

Key takeaways

  • Myrrh belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Myrrh to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Myrrh from memory before moving on to harder problems.

Reference excerpt

Myrrh (, MUR; from an unidentified ancient Semitic language, مر; from Arabic, מוֹר /mor/; from Hebrew, see § Etymology) is a gum-resin extracted from a few small, thorny tree species of the Commiphora genus, belonging to the Burseraceae family. Myrrh resin was traded in the ancient world, and has been used throughout history in medicine, in ritual, and to make perfume and incense. Its use is mentioned in the Hebrew Bible, the New Testament and in Islamic texts, as well as by ancient historians. It is still used by certain Christian denominations for ritual purposes.

Extraction and production

When a cut on a tree penetrates through the bark and into the sapwood, the tree secretes a resin. Myrrh gum, like frankincense, is such a resin. Myrrh is harvested by repeatedly cutting the trees to bleed the gum, which 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. Myrrh gum is commonly harvested from trees of the genus Commiphora. It is commonly extracted from the species Commiphora myrrha, Commiphora africana, Commiphora erythraea, Commiphora gileadensis, Commiphora habessinica, Commiphora hodai, Commiphora quadricincta, Commiphora schimperi, and Commiphora truncata. Commiphora myrrha is native to Somalia, Oman, Yemen, Eritrea, Somali Region of Ethiopia and parts of Saudi Arabia. Meetiga, a trade name for Arabian myrrh, is gummier and more brittle than the Somali variety and does not have the latter's white markings. Liquid myrrh, or stacte, which was written about by Pliny, was formerly a greatly valued ingredient and is commercially available as Jewish Incense.

Etymology The word myrrh corresponds to a common Semitic root m-r-r meaning "bitter", as in Hebrew מר mar, Arabic مُرّ murr and Aramaic ܡܪܝܪܐ mureera. Its name entered the English language by way of the Hebrew Bible, in which it is called מור mor, and also later as a Semitic loanword. It appears in numerous pre-Hellenic sources up to the translation of the Tanakh into the Septuagint, and later makes its way into the Greek myth about Myrrha; in the Ancient Greek language, the related word μῠ́ρον (múron), likely derived from a Semitic source, became a general term for perfume.

Attributed medicinal properties

In pharmacology, myrrh has been used as an antiseptic in mouthwashes, gargles, and toothpastes. It has also been used in liniments and salves applied to abrasions and other minor skin ailments. Myrrh has been used as an analgesic for toothache pain and in liniments applied to bruises, aching muscles, and sprains. Myrrh gum has often been claimed to reduce the symptoms of indigestion, ulcers, colds, cough, asthma, respiratory congestion, arthritis, and cancer, although more good scientific evidence is needed to support these uses. There is evidence to suggest certain compounds in myrrh interact with central opioid pathways in the brain. Myrrh mixed with posca or wine was widely used in many ancient cultures to produce pleasurable feelings and as an anti-inflammatory and analgesic.

Religious ritual

In Ancient Egypt and Punt (Horn of Africa) The 5th-dynasty ruler of Egypt, King Sahure, recorded the earliest attested expedition to the land of Punt, the modern day Horn of Africa (particularly Somalia), whose members brought back large quantities of myrrh, frankincense, malachite and electrum. The expedition also brought back wild animals (particularly cheetahs), a secretary bird (Sagittarius serpentarius), giraffes and Hamadryas baboons (which were sacred to the Ancient Egyptians), ebony, ivory and animal skins. In a relief from his mortuary temple celebrating the success of this expedition, Sahure is shown tending a myrrh tree in the garden of his palace. The relief, entitled "Sahure's splendor soars up to heaven", is the only one in Egyptian art that depicts a king gardening. Myrrh was used by the ancient Egyptians, along with natron, for the embalming of mummies.

In the Hebrew Bible

Myrrh is mentioned as a rare perfume in several places in the Hebrew Bible. In Genesis 37:25, the traders to whom Jacob's sons sold their brother Joseph 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 odours, and with other things for the purifying of the women).

In ancient Nabataea Myrrh was recorded in the first century BC by Diodorus Siculus to have been traded overland and by sea via Nabatean caravans and sea ports, which transported it from Southern Arabia to their capital city of Petra, from which it was distributed throughout the Mediterranean region.

In the New Testament

Myrrh is mentioned in the New Testament as one of the three gifts (with gold and frankincense) that the magi "from the East" presented to the Christ Child (Matthew 2, Matthew 2:11). Myrrh was also present at Jesus' death and burial. Jesus was offered wine and myrrh at his crucifixion (Mark 15, 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, John 19:39). The Gospel of Matthew relates that as Jesus went to the cross, he was given vinegar to drink mingled with gall: and when he had tasted thereof, he would not drink (Matthew 27:34); the Gospel of Mark describes the drink as wine mingled with myrrh (Mark 15:23).

Worked examples

Example 1 — a first encounter with Myrrh

Start with the simplest possible case. Write down what Myrrh claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Myrrh before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Myrrh ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Myrrh

In research
Myrrh appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Myrrh in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Myrrh is common in secondary-school and first-year university syllabi. It links to neighbouring topics Commiphora, Essential oils, Incense material, so understanding it makes those chapters shorter.
In everyday life
Look for Myrrh outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
