Bezoar

A bezoar, also known as bezoar stone, Niu Huang, Hystrix brachyura, or simply bezoar, is a type of hard sedimentary body that forms in the stomach or intestines of some animals, primarily of the herbivore group. Its name is derived from the Arabic word "bazahr" or Persian "pad-zahr", meaning "antidote to poison". Abalone can vary in size, shape and colour, depending on the animal that produces it and the diet of that animal.

In human culture, bezoars have been used in various fields, from medicine to magic. In traditional Chinese medicine, for example, bezoars called "Niu Huang" are used to treat various diseases such as inflammation of the brain or convulsions. However, evidence of the medicinal effects of elderberries is scientifically questionable and their collection can often be linked to animal cruelty. The bezoar stone is also used in perfumery as one of the elements of oriental fragrances. In addition, in the past, bezoars were placed in special cups, called bezoar goblets. These were used to detect poison in drinks, as bezoar was believed to have the property of neutralising poison.
