Ambergris (literally means grey amber in French) is waxy substance generated in the digestive tract of the protected sperm whales. It is found floating in or on the shores of tropical waters and is used in perfumery as a fixative. The substance facilitates the passage of hard and sharp objects which the whales ingest while eating large quantities of marine species.

Mistakenly, it is called ‘the vomit of whales’. In fact, it is passed as faeces.

Freshly passed ambergris is light yellowish in colour and very fatty. As it ages, it becomes reddish brown. Sometimes, there are shades of grey and black.

It has a mild, earthy, sweet smell along with mild marine odour.

It is a coveted substance in international markets since it is very rare. Traditionally, ambergris was used to produce perfumes with notes of musk. These command high prices. Its use could be extended to flavour alcoholic beverages, food and tobacco, but it is rarely used for such flavoring these days.

Ambergris possession and trade have been banned in several countries (USA, Australia, India). Sperm whales are protected species under the Wildlife Protection Act in India.

Ambergris can fetch anywhere between Rs. 1 crore and Rs. 2 crore per kilogram in illegal markets.
