Ambergris – New Zealand
One of the few things on this list that sounds less gross than it is, ambergris is is a solid, waxy substance originating in the intestine of sperm whales.
When the sperm whale releases its bowels, the ambergris is usually expelled through the rectum. The chunks float onto the surface where the sun sterilizes and cooks them.
Apparently someone thought this would make a good beauty treatment at some point and is usually powered and turned into an eye cream and is also used in many perfumes and oil.
