Ambergris.
Some sperm whales secrete ambergris to aid digestion, which is usually shed as they excrete, although it is often referred to as “whale vomit”.
Ambergris usually hardens when exposed to sunlight, air and sea water.
Ambrein is the main ingredient in ambergris or sperm whale droppings, which keeps the scent on the skin for hours and has been shown to stimulate libido in rats.
But the chance to find ambergris is very rare because there are only about 200,000 sperm whales left in the world. Because the sperm whale is an endangered species, ambergris is banned in the US, but it is still highly valued in many countries such as France.
