Ambergris (/ˈæmbərɡrs/ or /ˈæmbərɡrɪs/, Latin: ambra grisea, Old French: ambre gris), ambergrease, or grey amber, is a solid, waxy, flammable substance of a dull grey or blackish colour produced in the digestive system of sperm whales.[1] Freshly produced ambergris has a marine, fecal odor. It acquires a sweet, earthy scent as it ages, commonly likened to the fragrance of rubbing alcohol without the vaporous chemical astringency.[2]

Ambergris from the North Sea

Ambergris has been highly valued by perfume makers as a fixative that allows the scent to endure much longer, although it has been mostly replaced by synthetic ambroxide.[3] Dogs are attracted to the smell of ambergris and are sometimes used by ambergris searchers.[4]


The word ambergris comes from the Old French "ambre gris" or "grey amber".[5][6] The word "amber" comes from the same source, but it has been applied almost exclusively to fossilized tree resins from the Baltic region since the late 13th century in Europe.

Furthermore, the word "amber" is derived from the Middle Persian (Pahlavi) word ambar (variants: ’mbl, 'nbl).


Ambergris is formed from a secretion of the bile duct in the intestines of the sperm whale, and can be found floating on the sea or washed up on coastlines. It is sometimes found in the abdomens of dead sperm whales.[5] Because the beaks of giant squids have been discovered within lumps of ambergris, scientists have theorized that the substance is produced by the whale's gastrointestinal tract to ease the passage of hard, sharp objects that it may have eaten.

Ambergris is passed like fecal matter. It is speculated that an ambergris mass too large to be passed through the intestines is expelled via the mouth, but this remains under debate.[7] Ambergris takes years to form. Christopher Kemp, the author of Floating Gold: A Natural (and Unnatural) History of Ambergris, says that it is only produced by sperm whales, and only by an estimated one percent of them. Ambergris is rare; once expelled by a whale, it often floats for years before making landfall.[8] The slim chances of finding ambergris and the legal ambiguity involved led perfume makers away from ambergris, and led chemists on a quest to find viable alternatives.[9]

Ambergris is found in primarily the Atlantic Ocean and on the coasts of South Africa; Brazil; Madagascar; the East Indies; The Maldives; China; Japan; India; Australia; New Zealand; and the Molucca Islands. Most commercially collected ambergris comes from the Bahamas in the Atlantic, particularly New Providence. In 2021, fishermen found a 280 pound piece of ambergris off the coast of Yemen, valued at $1.5 million dollars.[10] Fossilised ambergris from 1.75 million years ago has also been found.[11]

Physical propertiesEdit

Ambergris is found in lumps of various shapes and sizes, usually weighing from 15 grams (12 ounce) to 50 kilograms (110 pounds) or more.[5] When initially expelled by or removed from the whale, the fatty precursor of ambergris is pale white in color (sometimes streaked with black), soft, with a strong fecal smell. Following months to years of photodegradation and oxidation in the ocean, this precursor gradually hardens, developing a dark grey or black color, a crusty and waxy texture, and a peculiar odor that is at once sweet, earthy, marine, and animalic. Its scent has been generally described as a vastly richer and smoother version of isopropanol without its stinging harshness. In this developed condition, ambergris has a specific gravity ranging from 0.780 to 0.926. It melts at about 62 °C (144 °F) to a fatty, yellow resinous liquid; and at 100 °C (212 °F) it is volatilised into a white vapor. It is soluble in ether, and in volatile and fixed oils.[5]

Chemical propertiesEdit

Ambergris is relatively nonreactive to acid. White crystals of a terpene known as ambrein, discovered by Ružička and Fernand Lardon in 1946,[12][13][14] can be separated from ambergris by heating raw ambergris in alcohol, then allowing the resulting solution to cool. Breakdown of the relatively scentless ambrein through oxidation produces ambroxan and ambrinol, the main odor components of ambergris.

Ambroxan is now produced synthetically and used extensively in the perfume industry.[15]


Ambergris has been mostly known for its use in creating perfume and fragrance much like musk. Perfumes can still be found with ambergris.[16] Ambergris has historically been used in food and drink. A serving of eggs and ambergris was reportedly King Charles II of England's favorite dish.[17] A recipe for Rum Shrub liqueur from the mid 19th century called for a thread of ambergris to be added to rum, almonds, cloves, cassia, and the peel of oranges in making a cocktail from The English and Australian Cookery Book.[18] It has been used as a flavoring agent in Turkish coffee[19] and in hot chocolate in 18th century Europe.[20] The substance is considered an aphrodisiac in some cultures.[21]

Ancient Egyptians burned ambergris as incense, while in modern Egypt ambergris is used for scenting cigarettes.[22] The ancient Chinese called the substance "dragon's spittle fragrance".[23] During the Black Death in Europe, people believed that carrying a ball of ambergris could help prevent them from contracting plague. This was because the fragrance covered the smell of the air which was believed to be a cause of plague.

During the Middle Ages, Europeans used ambergris as a medication for headaches, colds, epilepsy, and other ailments.[23]


From the 18th to the mid-19th century, the whaling industry prospered. By some reports, nearly 50,000 whales, including sperm whales, were killed each year. Throughout the 1800s, "millions of whales were killed for their oil, whalebone, and ambergris" to fuel profits, and they soon became endangered as a species as a result.[24] Due to studies showing that the whale populations were being threatened, the International Whaling Commission instituted a moratorium on commercial whaling in 1982. Although ambergris is not harvested from whales, many countries also ban the trade of ambergris as part of the more general ban on the hunting and exploitation of whales.

Urine, faeces and ambergris (that has been naturally excreted by a sperm whale) are waste products not considered parts or derivatives of a CITES species and are therefore not covered by the provisions of the convention.[25]



In popular cultureEdit


The knowledge of ambergris and how it is produced may have been a kept secret. Ibn Battuta wrote about ambergris, "I sent along with them all the things that I valued and the gems and ambergris..."[29] Glaswegian apothecary John Spreul told the historian Robert Wodrow about the substance but said he had never told anyone else.[30]

In literatureEdit

In chapter 91 of Herman Melville's Moby-Dick (1851), Stubb, one of the mates of the Pequod, fools the captain of a French whaler (Rose-bud) into abandoning the corpse of a sperm whale found floating in the sea. His plan is to recover the corpse himself in hopes that it contains ambergris. His hope proves well founded, and the Pequod's crew recovers a valuable quantity of the substance.[31] Melville devotes the following chapter to a discussion of ambergris, with special attention to the irony that "fine ladies and gentlemen should regale themselves with an essence found in the inglorious bowels of a sick whale."[32]

In "A Romance of Perfume Lands or the Search for Capt. Jacob Cole", F. S. Clifford, October 1881, the last chapter concerns one of the novel's characters discovering an area of a remote island which contains large amounts of ambergris. He hopes to use this knowledge to help make his fortune in the manufacture of perfumes.[33]

In filmEdit

In Hannibal, the sequel to The Silence of the Lambs, FBI Special Agent Clarice Starling is entangled on the manhunt of cannibal serial killer Hannibal Lecter, who successfully escaped imprisonment in the first film after becoming somewhat friendly with her. After realizing that he was put back on FBI's Top 10 Most Wanted list, and assuming Agent Starling has been assigned the case, Lecter decides to provoke his hunter by outsmarting her and the Bureau institution once again. In one of his affronts, he sends Agent Starling a letter. Being acquainted with his flamboyant tricks, she has the envelope and letter analyzed for smell. A team of specialists find traces of a lavender and ambergris hand cream he was using while writing the letter. Since the substance is so highly regulated and rare to find, she is able to determine just a few stores which sell it, and through surveillance footage of a store in Florence, he is publicly sighted for the first time in a decade, which ultimately leads to their encounter.[citation needed]
