In the "Youyang Miscellanies" of the Tang Dynasty; It is said that the saliva foam of A Xiang dragon was condensed. As a matter of fact, Long Xianxiang is a whale, mainly a sperm whale. It swallows some foreign bodies such as marine life, and wraps the secretions produced by stimulating the intestines to form solid substances, which have been floating in the sea for decades or even hundreds of years.
Most newcomers are black, gray and white.

What makes it so amazing?
Wang said that modern chemical analysis showed that it mainly contained ambergris alcohol (about 25%), Long Xianxiang aldehyde and other compounds, as well as feces such as sterols and cholesterol. In addition, there are metal elements such as calcium, magnesium, phosphorus, copper, gallium, zinc, aluminum, manganese and strontium.

How to identify Long Xianxiang?

He said that according to the above sources, we can know that the Long Xianxiang that has just been discharged has a foul smell, which is light black; Under the action of seawater, it will gradually turn gray, light gray and finally white with time.
Its dry product is fragrant, and the white one is the best. He said that it is not common because its origin and formation process are very complicated. Personally, in order to identify Long Xianxiang, it is necessary to have relevant knowledge of biology, ecology and chemistry, especially professionals who are familiar with marine life and marine ecology, so as to make an accurate identification.
