Understanding Castoreum
Castoreum is an oily and fragrant secretion produced by the castor sacs found in two species of beavers: the Eurasian beaver (Castor fiber) and the North American beaver (Castor canadensis). These sacs are located near the animals' genital tracts and serve essential biological functions. They help beavers identify one another, mark their territories, regulate their population, and facilitate reproduction through pheromonal activity.
Besides these functions, castoreum also waterproofs the beavers' fur. It has been utilized for various purposes since ancient times, with mentions in Byzantine-era medical texts. Castoreum has been used in perfumes since that period, and beavers were also hunted for their fur and meat. Trappers once utilized castoreum to lure carnivorous animals to their traps. Historically, it was believed to treat uterine diseases, fevers, headaches, epilepsy, and surgical wounds. However, castoreum is no longer considered a therapeutic agent and is primarily used in the perfume industry.
The Sensual Scent of Castoreum
In modern perfumery, there are six animal-derived raw materials: musk, ambergris, civet, beeswax, and castoreum. In its pure state, castoreum has an aggressive odor, but when diluted, it becomes softer and warmer, evoking leather and fur. This valuable substance is mainly used in amber, oriental, and masculine perfumes. However, the use of castoreum in perfumery is declining due to the need to kill the animal to extract it. As a result, perfumers often produce synthetic equivalents. Despite technological advances, synthetic castoreum lacks the original's finesse. In addition to perfumery, castoreum is used to flavor cigarettes and certain candies.
Due to its high cost, castoreum is typically found in prestigious perfumes, such as Antaeus by Chanel, Bel Ami by Hermès, or Dolce Vita by Dior.
