Beaver butt perfume, or castoreum, has been used for centuries in the perfume industry. It is a yellowish secretion from the castor sacs of beavers, located near the base of their tails. While it is often associated with anal secretions, the castoreum used in perfumes is typically extracted from the dried and crushed castor sacs of dead beavers. Beavers use castoreum to mark their territory, and it is known for its scent of dried leather. In perfumes, it is used as a base note, providing a deep and lingering scent. While castoreum has a long history of use, it is now rarely included in perfumes due to the expense and inconvenience of harvesting it from live beavers.

Beaver butt perfume is made from castoreum, a secretion from the beaver's castor sacs
The use of castoreum in perfumes dates back centuries, with the American beaver trade bringing it into the spotlight as a perfume ingredient. Its scent has been described as "kind of sexy, kind of dark," resembling Russian leather. In perfumery, castoreum is often compounded with other ingredients, including top, middle, and base notes, to create a deep and lingering aroma.
While the use of castoreum in perfumes has a long history, its utilisation has decreased due to the inconvenience and expense of harvesting it from live beavers. The process involves anesthetising the beavers and milking their castor glands, which is challenging and time-consuming. As a result, castoreum is now rarely used in perfumes, with the annual industry consumption being relatively low.
In addition to its use in perfumery, castoreum has also been utilised as a food additive and for medicinal purposes throughout history. However, due to its association with the anal region and the difficulty in obtaining it, castoreum is not commonly found in mass-marketed goods today.

It has been used as a perfume ingredient for centuries, often for its leather-like scent
Beaver castor sac secretions, or castoreum, have been used as a perfume ingredient for centuries. The substance is a yellowish exudate from the castor sacs of mature beavers, located near the base of their tails. Both male and female beavers possess a pair of these sacs, which are used to secrete castoreum in combination with urine to mark their territory.
Castoreum has been valued for its leather-like scent in perfumery. It is often used as a base note, providing a deep, lingering aroma. The compound is aged for two or more years to mellow and is then compounded with other ingredients, including top, middle, and base notes, to create a well-rounded fragrance. Some classic perfumes that are said to incorporate castoreum include Emeraude, Chanel Antaeus, Cuir de Russie, Magie Noire, and Shalimar.
The use of castoreum in perfumery dates back to ancient times. It was also used in soaps and creams, and even added to cigarettes to enhance their scent. The popularity of castoreum in the perfume industry is due in part to its chemical composition, which contains a diverse range of over 75 different chemical compounds, including several pheromones.
While the use of castoreum in modern perfumery is less common due to its inconvenience and expense, it continues to be valued for its unique scent and fixative properties, enhancing and prolonging the fragrance of other ingredients.

Castoreum is also used as a food additive, though this is now rare due to its expense
Castoreum, a secretion produced by beavers, has been used as a food additive and flavouring agent in various products, including alcoholic beverages, baked goods, frozen dairy, chewing gum, candy, meat products, pudding, gelatin, ice cream, and vanilla and raspberry flavourings. However, its usage in the food industry has become rare due to its expense.
The process of obtaining castoreum involves milking or extracting it from live beavers, which can be challenging and costly. In addition, the annual industry consumption of castoreum is very low, with alternative options like natural vanillin being preferred.
Castoreum has a strong and unique scent, often described as resembling dried or Russian leather. This has made it more popular in the fragrance industry, where it is used as a base note to enhance and prolong the scent of perfumes.
While castoreum has been used in traditional medicine and food flavouring for centuries, its demand has decreased significantly. Today, it is rarely used as a food additive due to its high cost and the availability of alternative options.
It's important to note that the use of castoreum in food products is not common, and it is not likely to be found in mass-marketed goods. The chances of encountering castoreum in today's "natural flavours" are slim, and it is mostly used in high-end fragrances.

It has been used as traditional medicine for centuries, treating everything from epilepsy to constipation
Beaver castoreum has been used as a traditional medicine for centuries, treating a wide range of ailments. Its use as a medicine dates back to antiquity, and it was particularly popular in the 19th century. Roman women, for instance, inhaled the fumes of burning castoreum as they believed it would induce abortions (though it didn't). Hildegard von Bingen, a 12th-century Benedictine abbess, wrote that powdered beaver "testicles" drunk in wine would reduce a fever. Castoreum was also used to treat headaches, earaches, toothaches, colic, gout, insomnia, and general brain strengthening. This was due, in part, to its salicylic acid content, the main ingredient in aspirin.
The demand for beaver pelts and castoreum in the 19th century almost led to the extinction of North American beavers. The Hudson Bay Company, a major trader in beaver pelts and castoreum, noted in 1894 that "the beaver's days are numbered. He cannot coexist with civilization."
While the use of castoreum as a medicine has declined, it is still occasionally used in traditional medicine. For example, Swedish trappers traditionally consume a castoreum-flavoured schnapps called Bäverhojt before a day of hunting.
Today, castoreum is more commonly used in the perfume industry, where it is valued for its deep, lingering scent of leather. It is also sometimes used as a food additive, though this is now rare due to its expense and the fact that it is not kosher.

Today, beaver butt perfume is considered an expensive, luxury ingredient
Beaver castoreum, commonly referred to as "beaver butt", is considered an expensive, luxury ingredient in perfumes today. While it has been used in perfumery for centuries, the process of extracting castoreum from beavers is challenging and costly.
Castoreum is a yellowish secretion produced by both male and female beavers from pouch-like sacs located near the base of their tails. To obtain castoreum, one must either milk the castoreum gland from a live beaver or remove the entire gland from a dead beaver and extract the castoreum with alcohol. The former method is considered more humane but is also more expensive and inconvenient. Due to the difficulty in obtaining castoreum, it is now rarely used in food products, with annual industry consumption being very low at around 300 pounds.
However, castoreum remains sought-after in the fragrance industry, where it is prized for its deep, leather-like scent. It is often used as a base note in perfumes, providing a lingering aroma that is "kind of sexy, kind of dark," according to perfumer-historian Mandy Aftel. The process of extracting and ageing castoreum contributes to its high cost, making it a luxury ingredient in perfumery.
The expense and rarity of castoreum are further exacerbated by the decline in beaver populations due to historical overhunting and trapping. Today, beavers are generally no longer hunted for their pelts or castoreum, and the substance is primarily obtained from live beavers through the milking process. This ethical sourcing method ensures the sustainability of beaver populations but further contributes to the high cost of castoreum.
While castoreum may be controversial due to its anal adjacency and association with "beaver butt," it has been deemed safe for human consumption by regulatory bodies. Its rarity and unique aroma have transformed it into a luxurious and exclusive ingredient in the perfume industry.
